TC94A39FAG/FB
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC94A39FAG, TC94A39FB
Single-Chip CD Processor with Built-in Controller (CD-DX)
The TC94A39FAG/FB is a single-chip CD processor for digital servo, which incorporates a 4-bit microcontroller. The controller features an LCD driver, 4-channel 6-bit AD converter, 1 port 2-channel 2/3-line or UART serial interface module, a buzzer, 20-bit general-purpose counter function, interrupt function, and 8-bit timer/counter. The CPU can select one of four operating clocks (16.9344-MHz, 75-kHz or 32.768-kHz crystal oscillator and CR oscillator), facilitating interface with the CD processor. The CD processor incorporates sync separation protection and interpolation, EFM demodulator, error correction, digital equalizer for servo, and servo controller. The CD processor also incorporates a 1-bit DA converter. In combination with the TA2157F/FN digital servo head amplifier, the TC94A39FAG/FB can very simply configure an adjustment-free CD player. Thus, the IC is suitable for CD systems for automobiles and radio-cassette players.

Pin Functions
Pin No. Symbol Pin Name Function and Operation System reset input pin for the device. A reset is applied while the RESET signal is low. When it is high, the 16.9344-MHz crystal oscillator (XI, XO) starts operating. The controller counts clock pulses from this oscillator and waits a specified standby time (approximately 50 ms) before starting the controller program from address 0. The CD processor is placed in the standby state at this time. Normally, raising the voltage on MVDD from 0 to 1.8 V or higher triggers a system reset (power-on reset) so that the RESET pin should be held at high. MVDD Remarks

MVDD
2-bit CMOS I/O port. Input/output can be specified for each bit. When the pins are used as I/O port input, each pin can be pulled up or down by program. When backup release for clock stop mode or wait mode is enabled for the pins, a change in a pin can release the backup state. The program can set these pins to be used for a 75-kHz or 32.768-kHz dedicated crystal oscillator. The P8-0 pin can also be used for a CR oscillator. These clocks are used for the operation of the controller and peripheral devices. Upon a system reset, the 16.9344-MHz crystal oscillator (XI, XO) is selected as the clock for controller and peripheral device operation. The program can subsequently set the pins to oscillator pins and switch the clock generated from the oscillator to the controller clock. When the pins are used for an oscillator, executing the CKSTP instruction causes its oscillation to stop. (Note) When the P8-0 pin is used for a CR oscillator, the P8-1 pin can used as an I/O port pin. MVDD Input instructio RIN1

When the P6-0 to P6-3 pins are used as I/O port input, each pin can be pulled up or down by program. When the P5-1 (BRK3) to P7-2 (BRK16) pins I/O port 2 are used as I/O port input and backup release /LCD common output for clock stop mode or wait mode is enabled for those pins (enabled/disabled in port units), a change in any of the pins can release the backup state. The P7-0 to P7-2 pins constitute an N-channel open-drain I/O port, to which a voltage of up to 5.5 V can be applied. I/O ports 2 to 6 can be set to LCD driver output pins by program. The COM1 to COM4 pins drive common signals to the LCD panel while the S1 to S16 pins drive segment signals. The COM1 to COM4 signals configure a matrix with the S1 to S16 signals to display up to 64 segments. When the LCDoff bit is set to 0, the COM1 to COM4 and S1 to S4 pins are collectively set to LCD output. For S5 to S16, the program can specify either I/O port or segment output individually for each pin.

Test input /I/O port 3-0 The LCD can be driven by the 1/4-duty, 1/2-bias /LCD segment output method (frame frequency: 62.5 Hz) or the 1/4-duty, 1/3-bias method (frame frequency: 125 Input Hz). When the 1/2 bias method is set, three instruction common output levels (MVDD, 1/2MVDD and RIN2 GND) and two segment output levels (MVDD and GND) appear on the pins. When the 1/3 bias method is set, four common and segment output levels (MVDD, 1/3MVDD, 2/3MVDD and GND) appear on the pins. Upon a system reset or after clock stop mode is released, a non-select waveform (bias voltage) is driven and the DISP OFF bit is set to 0, after which the common signals are driven. During a system reset ( RESET = low), the TEST/P3-0/S1 pin is pulled down and accepts test mode input. This pin should be left open or applied low level during a reset. The P5-1 to P6-3 and P1-0 to P1-2 pins can be set to CD processor-dedicated pins on a per pin basis.

The /CD processor TC94A39FAG/FB has CMOS input/output pins function (SCK1/RX1, SDIO1/TX1, SI1) and N-channel open-drain (supporting up to 5.5 V) input/output pins (SCK2/RX2, SDIO2/TX2, SI2). One of the two sets of pins can be selected as serial interface. The serial interface circuit supports various options, including the number of the I/O port 1-3 clock edge to be used, the serial clock /buzzer output input/output, and the clock frequency. These options facilitate controlling the LSI and communications between the controllers. When SIO interrupts are enabled, an interrupt is generated as soon as execution of the SIO completes, causing the program to jump to I/O port 7-0 address 4. /serial clock The P1-3 pin has multiplexed functions for a input/output 2 /serial receive data 2 buzzer output pin.
