2 GENERAL DESCRIPTION

GPC71PXXXA, a 4-bit sound controller, is architected with a

one-channel SPU for MIDI playback, a 4-bit RISC CPU, a 14-bit

PWM, 8/16 IOs, 256-nibble RAM, and OTP with density of 680K/

340K/ 160K/ 128K/ 96K/ 64K/ 32K x 12-bit of memory space.

The operating voltage ranges from 2.0V through 5.5V and

operating speed is 1M/2MHz, configurable through inner oscillator.

Other features include Low Voltage Reset, IR carry output,

watchdog, five interrupt sources with two time-bases, etc.
