GPC71P170B, 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 IOs, 1 input (with pull low resistor ), 256-nibble RAM, and OTP with density of 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.
