General Description

GPC72080D, a 4-bit sound controller, is architected with a four-channel SPU for MIDI playback, a 4-bit RISC CPU, a 14-bit PWM, 11 IOs, 1 input (with pull low resistor), 256-nibble RAM, and OTP with density of 320K x 6-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.
