juno tm family communications interface copyright ?998-2001 semtech corporation doc8-007-004-ds-103 www.semtech.com 7 the juno ? family of controllers implements two modes of serial communications: the "synchronous peripheral interface" (spi) mode and the "asynchronous serial interface" (asi). the spi is a synchronous bi- directional, multi-slave interface that supports bit rates up to 500 kb/s. several hosts and companion chips implement the spi protocol in order to communicate with a wide range of peripherals such as eeproms, a/d converters, mcus and other system components. alternatively, the spi may be implemented through software on the host side. the juno ? family implements the _atn as an additional hand-shake signal in order to support low power operation of the bus. the asi is an asynchronous interface (uart type) that operates at a fixed baud rate of 62.5 kb/s. both interfaces are implemented through the same set of four pins. the ic determines the mode of communication with the host during power-up by reading the value of the sclk/isel pin. if the pin is tied low, the asi mode is enabled. if it is high, the spi interface is enabled. please refer to the juno tm 04 technical reference manual for a description of handshake and critical timing parameters for each interface. the diagrams below describe the spi and asi communications interfaces, respectively. spi communications interface host (master) mosi miso sclk _ss _atn usar juno ?

protocols, commands and reports copyright ?998-2001 semtech corporation doc8-007-004-ds-103 www.semtech.com 8 overview the juno ? ur8hc007-004 implements and supports four types of transaction messages. 1. commands from the ic to the host system 2. commands from the host system to the ic 3. human input device (hid) reports to the system 4. event alert messages to the system the protocol is fundamentally implemented through a set of general packet commands that allow handling and reporting of each individual controller register and each bit within each register. in this manner, the system achieves maximum flexibility in manipulating the operation of the ur8hc007-004 controller. general message structure communications between the juno ? ur8hc007-004 and the host processor are implemented using a set of packet protocols and commands. the general structure of a message is shown in the following diagram: general message format the protocol header identifies the type of transaction. the following table lists the available protocols. protocol headers protocols used in commands issued by the host protocol header simple commands 80h write register bit 81h read register bit 82h write register 83h read register 84h write block 85h read block 86h protocols used in responses, reports and alerts issued by the controller protocol header simple commands 80h report register bit & event alerts 81h report register 83h report block 85h relative pointer data report 87h keyboard ps/2 code data report 88h absolute pointer data report 89h keyboard key code (position) report 8ah protocol header command/report identifier message body (if applicable) lrc

power management modes of operation power management copyright ?998-2001 semtech corporation doc8-007-004-ds-103 www.semtech.com 11 the juno tm family has three modes of operation relating to its power consumption. the "stop" mode is the lowest power consumption mode. in this mode, the crystal is stopped and the ic consumes only 1 ? of leakage current. this is the default mode to which the ic will revert any time an event or a signal condition does not force it to exit this mode. the "wait" mode is entered each time it is necessary for a timer to be running in order to perform a system function. such functions include the led blinking mode and the use of one of the pwm channels. typical power consumption in this mode is several hundred ?s. the "run" mode is entered briefly, only to process an event or while an interrupt-generating signal condition persists. the controller ic will remain in this mode only for as long a signal prohibits it from reentering a lower power consumption mode or for as long as it is necessary to process a host-related transaction (a few milliseconds). the juno ? ur8hc007 family of controllers implements two power management methods: system-coordinated power management and self-power management ? (spm). system-coordinated power management primarily determines the tasks performed and the type of reports communicated to the host. the juno ? 04 monitors the system states through the pwrok (power ok), _lid (lid closed) and _hsus (host suspended) lines. in addition to these signal inputs, the ur8hc007 family provides a set of registers, described in the "registers" chapter of the juno tm 04 technical reference manual , that can be used by the host to control the pm-related performance of the controller through software. according to the status of these lines (or register settings), the juno ? 04 will enable or disable specific tasks and reports suited to the current power and system management state of the host. self-power management ? describes a method implemented by the juno ? family of controllers that, independently of any system intervention, results in the lowest power consumption possible within the given parameters of its operation. through self-power management ? , the juno ? controllers are capable of typically operating at only 1 ?, independent of the state of the system. self-power management ? primarily determines the actual power consumption of the controller ic. the juno ? 04 implements the semtech-patented self-power management ? method to achieve the minimum power consumption possible, independent of the host power management state. even when the host is in the active state, the ic can still operate most of the time at only 1 ?, even with external ps/2 devices attached to it. critical suspend spm host suspend lid closed* pwrok=0 pwrok=0 pwrok=0 pwrok=1 and _lid=0 pwrok=1 and _lid=1 and _hsus=0 pwrok=1 and _lid=1 and _hsus=1 pwrok=1 and _lid=1 and _hsus=1 pwrok=1 and _lid=0 pwrok=1 and _lid=1 and _hsus=1 pwrok=1 and _lid=1 and _hsus=0 pwrok=1 and _lid=1 and _hsus=0 pwrok=1 and _lid=0
hid manager keyboard encoding copyright ?998-2001 semtech corporation doc8-007-004-ds-103 www.semtech.com 12 the ur8hc007-004 human input device (hid) manager is responsible for the configuration and handling of hid devices that are embedded or attached to the controller. the hid manager has the following responsibilities: 1. enabling and disabling embedded and attached input devices through the "hid enable/disable control" register 2. formatting and relaying input device reports to the host 3. controlling the configuration and operation of both embedded and attached input devices the hid manager consists of the two functional blocks: the keyboard manager and the pointing device manager. the function of each manager is explained in full in the juno tm 04 technical reference manual . the ur8hc007-004 will encode an 8-row by 16-column keyboard matrix. oems may reprogram the matrix by sending commands to the ic from the system. the juno tm 04 supports english, japanese and european keyboards. in addition, the ic supports both sticky keys and notebook-style keyboards. the keyboard below, the fujitsu fkb7654, is the default keyboard for the ur8hc007-004. tab q w e ctrl alt fn z space alt ctrl r t y u i o p z x c v b n m , . / <>? cap lock a s d f g h j k l ; ! 1 @ 2 # 3 $ 4 % 5 ^ 6 & 7 * 8 79 5 46 2 1 0 . / 3 + 8 ( 9 ) 0 _ - + = bk sp [ : ' " \ | ] {} shift shift esc f1 f2 f3 f4 f5 f6 f7 f8 f9 f10 f11 f12 sl nl pau brk ins prt del srq pgup pgup pgup pgup ~ ` enter the juno tm 04 provides many gpio pins which enable oems to easily differentiate their products. four gpio ports provide interrupt at both falling and rising edge of signals. two of these pins are dedicated for use as a lid indicator and digital power monitor. the other two may be used for a ring indicator, docking signal, soft power button, etc. three gpio pins provide a/d input and are ideal for battery measurement. three gpio pins provide two pulse width modulation (pwm) channels and one d/a channel and may be used for analog control functions such as lcd brightness/contrast or audio volume control. four gpio pins with high drive ability are set aside as led drivers or i/o. eight gpio pins can be used as system control outputs or inputs, for example, for switches. fujitsu fkb7654 other members of the juno tm series of companion ics offers advanced, ergonomic control of an internal pointing device. enabled pointing devices include touch pads or force sticks. if the application requires an internal pointing device, using a pointing-enabled juno tm will eliminate the need for a dedicated mouse encoder ic. other juno tm series members general purpose input output
juno tm 04 pointing device manager copyright ?998-2001 semtech corporation doc8-007-004-ds-103 www.semtech.com 13 the juno tm 04 pointing device manager has the following features: pin drive or device drive detection the designer can select one of two configurations for touchscreen driving: with hardware driver (device drive) and without (pin drive). the juno ? 04 can detect the configuration automatically at power-up and behave properly for that configuration. the touch and motion qualities are exactly the same for both configurations. for more details, see the analytical pin descriptions for touchscreen in the "pin information" chapter. touch detection the pointing device manager periodically checks whether there is touch on touchscreen. if no touch is detected, the pointing device manager drives the touchscreen into power saving mode. if a touch is detected, touchscreen is forced into driving state and prepared for measurement. touch measurement when the pointing device manager detects a touch on touchscreen, it drives the touchscreen into drive state and does measurement. if the touch data is not good enough, the measured data are not used for the algorithm. only good touch data are used for the algorithm. touch algorithm due to hand shaking and electrical noise, the raw data can not be output directly. the pointing device manager uses a proprietary algorithm to process the data. sampling rate the sampling rate is 100 coordinate points per second. resolution the maximum touchscreen resolution is approximately 1000 points per direction. it varies with different touchscreens due to voltage drop on connection wires. touchscreens from different manufacturers touchscreens from different manufacturers have different parameters. the touchscreen parameters also depend on the size of touchscreen and material from which it is made. because the pointing device manager takes these properties into account, it can support almost any touchscreen.
