OVERVIEW (cont.)
The EP7311 is designed for low-power operation. Its core operates at only 2.5 V, while its I/O has an operation range of 2.5 V-3.3 V. The device has three basic power states: operating, idle and standby. One of its notable features is MaverickKey unique IDs. These are factory programmed IDs in response to the growing concern over secure web content and commerce. With Internet security playing an important role in the delivery of digital media such as books or music, traditional software methods are quickly becoming unreliable. The MaverickKey unique IDs consist of two registers, one 32-bit series register and one random 128bit register that may be used by an OEM for an authentication mechanism. Simply by adding desired memory and peripherals to the highly integrated EP7311 completes a low-power system solution. All necessary interface logic is integrated onchip.

EP7311 High-Performance, Low-Power System on Chip
Processor Core - ARM720T
The EP7311 incorporates an ARM 32-bit RISC microcontroller that controls a wide range of on-chip peripherals. The processor utilizes a three-stage pipeline consisting of fetch, decode and execute stages. Key features include: * ARM (32-bit) and Thumb (16-bit compressed) instruction sets * Enhanced MMU for Microsoft Windows CE and other operating systems * 8 KB of 4-way set-associative cache. * Translation Look Aside Buffers with 64 Translated Entries
Digital Music Initiative) or any other authentication mechanism. Both a specific 32-bit ID as well as a 128-bit random ID is programmed into the EP7311 through the use of laser probing technology. These IDs can then be used to match secure copyrighted content with the ID of the target device the EP7311 is powering, and then deliver the copyrighted information over a secure connection. In addition, secure transactions can benefit by also matching device IDs to server IDs. MaverickKey IDs provide a level of hardware security required for today's Internet appliances.
Memory Interfaces
There are two main external memory interfaces. The first one is the ROM/SRAM/FLASH-style interface that has programmable wait-state timings and includes burstmode capability, with six chip selects decoding six 256 MB sections of addressable space. For maximum flexibility, each bank can be specified to be 8-, 16-, or 32bits wide. This allows the use of 8-bit-wide boot ROM options to minimize overall system cost. The on-chip boot ROM can be used in product manufacturing to serially download system code into system FLASH memory. To further minimize system memory requirements and cost, the ARM Thumb instruction set is supported, providing for the use of high-speed 32-bit operations in 16-bit op-codes and yielding industryleading code density.

Power Management
The EP7311 is designed for ultra-low-power operation. Its core operates at only 2.5 V, while its I/O has an operation range of 2.5 V-3.3 V allowing the device to achieve a performance level equivalent to 60 MIPS. The device has three basic power states: * Operating -- This state is the full performance state. All the clocks and peripheral logic are enabled. * Idle -- This state is the same as the Operating State, except the CPU clock is halted while waiting for an event such as a key press. * Standby -- This state is equivalent to the computer being switched off (no display), and the main oscillator shut down. An event such as a key press can wake-up the processor.

The second is the programmable 16- or 32-bit-wide SDRAM interface that allows direct connection of up to two banks of SDRAM, totaling 512 Mb. To assure the lowest possible power consumption, the EP7311 supports self-refresh SDRAMs, which are placed in a low-power state by the device when it enters the lowpower Standby State.

64-Keypad Interface
Matrix keyboards and keypads can be easily read by the EP7311. A dedicated 8-bit column driver output generates strobes for each keyboard column signal. The pins of Port A, when configured as inputs, can be selectively OR'ed together to provide a keyboard interrupt that is capable of waking the system from a STANDBY or IDLE state. * Column outputs can be individually set high with the remaining bits left at high-impedance * Column outputs can be driven all-low, all-high, or allhigh-impedance * Keyboard interrupt driven by OR'ing together all Port A bits * Keyboard interrupt can be used to wake up the system * 8x8 keyboard matrix usable with no external logic, extra keys can be added with minimal glue logic

Interrupt Controller
When unexpected events arise during the execution of a program (i.e., interrupt or memory fault) an exception is usually generated. When these exceptions occur at the same time, a fixed priority system determines the order in which they are handled. The EP7311 interrupt controller has two interrupt types: interrupt request (IRQ) and fast interrupt request (FIQ). The interrupt controller has the ability to control interrupts from 22 different FIQ and IRQ sources. * Supports 22 interrupts from a variety of sources (such as UARTs, SSI1, and key matrix.) * Routes interrupt sources to the ARM720T's IRQ or FIQ (Fast IRQ) inputs * Five dedicated off-chip interrupt lines operate as level sensitive interrupts

The following table shows the pin multiplexing of the MCP, SSI2 and the CODEC. The selection between SSI2 and the CODEC is controlled by the state of the SERSEL bit in SYSCON2.

Assumes buffer has no pull-up or pull-down resistors. The leakage value given assumes that the pin is configured as an input pin but is not currently being driven. 1) All power dissipation values can be derived from taking the particular IDD current and multiplying by 2.5 V. 2) The RTC of the EP7311 should be brought up at room temperature. This is required because the RTC OSC will NOT function properly if it is brought up at -40C. Once operational, it will continue to operate down to -20C extended and 0C commercial. 3) A typical design will provide 3.3 V to the I/O supply (i.e., VDDIO), and 2.5 V to the remaining logic. This is to allow the I/O to be compatible with 3.3 V powered external logic (i.e., 3.3 V SDRAMs). 4) Pull-up current = 50 A typical at VDD = 3.3 V.

Figure 6. Static Memory Single Read Cycle Timing Measurement Note: 1. The cycle time can be extended by integer multiples of the clock period (27 ns at 36 MHz, 54 ns at 18.432 MHz, and 77 ns at 13 MHz), by either driving EXPRDY low and/or by programming a number of wait states. EXPRDY is sampled on the falling edge of EXPCLK before the data transfer. If low at this point, the transfer is delayed by one clock period where EXPRDY is sampled again. EXPCLK need not be referenced when driving EXPRDY, but is shown for clarity.

EXPCLK need not be referenced when driving EXPRDY, but is shown for clarity. 2. Zero wait states for sequential writes is not permitted for memory devices which use nMWE pin, as this cannot be driven with valid timing under zero wait state conditions.

Figure 8. Static Memory Burst Read Cycle Timing Measurement Note: 1. Four cycles are shown in the above diagram (minimum wait states, 1-0-0-0). This is the maximum number of consecutive cycles that can be driven. The number of consecutive cycles can be programmed from 2 to 4, inclusively. 2. The cycle time can be extended by integer multiples of the clock period (27 ns at 36 MHz, 54 ns at 18.432 MHz, and 77 ns at 13 MHz), by either driving EXPRDY low and/or by programming a number of wait states. EXPRDY is sampled on the falling edge of EXPCLK before the data transfer. If low at this point, the transfer is delayed by one clock period where EXPRDY is sampled again. EXPCLK need not be referenced when driving EXPRDY, but is shown for clarity. 3. Consecutive reads with sequential access enabled are identical except that the sequential access wait state field is used to determine the number of wait states, and no idle cycles are inserted between successive non-sequential ROM/expansion cycles. This improves performance so the SQAEN bit should always be set where possible.

General Conventions
Hexadecimal numbers are presented with all letters in uppercase and a lowercase "h" appended or with a 0x at the beginning. For example, 0x14 and 03CAh are hexadecimal numbers. Binary numbers are enclosed in single quotation marks when in text (for example, `11' designates a binary number). Numbers not indicated by an "h", 0x or quotation marks are decimal. Registers are referred to by acronym, with bits listed in brackets separated by a colon (:) (for example, CODR[7:0]), and are described in the EP7311 User's Manual. The use of "TBD" indicates values that are "to be determined," "n/a" designates "not available," and "n/c" indicates a pin that is a "no connect."
