7 FUNCTION DESCRIPTIONS

7.1 CPU

GPC74XXXA features a 4-bit RISC CPU , executing the 12-bit instruction set with total of 72 instructions available, 7 stacks managed by 3-bit stack pointer, three DPRs(Data Pointer to read ROM) sharing stack 4 ~ 6, and 8 VPRs(Voice Data Point er) for SPU.

7.2 Memory

7.2.1 SRAM

There are 256 nibbles of SRAM, grouped into 4 banks . Each bank has 64 nibbles and supports index mode to read/write its content addressed by TXR.

7.2.2 OTP

GPC74XXXA is equipped with 680K/ 340K/ 160K/ 128K/ 96K/ 64K/ 32K x 12-bit factory programmed OTP memory.

7.3 Clock Source

Clock source is an inner resistance oscillator with CPU clo ck options of 1MHz or 2MHz

7.4 Low Voltage Reset

With the LVR function, a reset signal is generated to reset system when the operating voltage drops below LVR level.

7.5 Interrupt

An interrupt is a special event request to microcontroller. When it occurs, the corresponding interrupt will activate and direct the program code to execute the respective functions. The GPC74XXXA has 5 interrupt sources . Please refer to programming guide for more details.

7.5.1 Timebase

There are two Time-base, TB1/TB2, generated by system clock. The interval of TB1 is allowed up to 1ms and TB2 is up to 2ms.

7.6 SPU

Four-channel SPU supports MIDI play back with A3400Pro -like decode or PCM format and each channel has an 8-bit envelop control.

7.7 PWM

The PWM module is a 14-bit PWM driver to drive speaker directly.

7.8 Sleep Mode, Wakeup and Watchdog

7.8.1 Sleep mode and wakeup

Sleep mode or known as power down mode is an operating state that requires an extremely low power consumption to maintain the system in active. The sleep mode is particularly useful for the application areas where the system is required to constantly maintain its basic functionality and where the power capacity is limited. GPC74XXXA will enter sleep mode when SLEEP instruction is executed and can be waked up by interrupt or key change. CPU will continue to execute the program from where it entered sleep mode.

7.8.2 Watchdog Reset

A watchdog reset is a reset signal that is generated to reset the entire system when watchdog counter is overflow. In case when the program code has been running into an unknown state and without the watchdog signal being cleared for a certain period of time, watchdog function automatically gen erates a reset signal pulling the system back from unknown state.

7.9 I/O

The GPC74XXXA features 16-bit or 8-bit programmable I/Os with wakeup capability . These IOs normally support input with floating or pull-low and output options. In addition to the ordinary I/O function, some IO ports have special functions. The following table summarizes the special functions for these IOs.

9 APPLICATION CIRCUITS

9.1 Light Loading and Circuit without Noise

PCB Layout Guidelines: 1. PVDD can be higher than or equal to VDD. 2. VSS and PVSS must be connected to ground input directly, not the branch of each other. 3. When using two batteries, 0.1uF ~ 4.7uF is suggested for C1, and it should be increased in a high volume application. 4. IOC/IOD isn’t supported in GPC74032A/GPC74016A. 5. There is no “TEST” pin in GPC74032A/GPC74016A. GPC74XXXA

9.2 Heavy Loading or Circuit with Noise

PCB Layout Guidelines: 1. PVDD can be higher than or equal to VDD. 2. VSS and PVSS must be connected to ground input directly, not the branch of each other. 3. A typical value of C1 is 47uf, and it should vary in different loadings. 4. If there is application with motor, REGOUT should be connected with C4. 5. IOC/IOD isn’t supported in GPC74032A/GPC74016A. 6. There is no “TEST” pin in GPC74032A/GPC74016A. GPC74XXXA
