GPC22P120A is embedded with an 8-bit processor, 512KB OTP, 256B SRAM, three 12-bit timers, 16 general I/Os, one pure input port, and one 12-bit current DAC. For audio processing, two channels of speech or two tone generators can be used through register configuration. GPC22P120A is designed to operate over a wide voltage range from 2.0V to 5.5V with Low Voltage Reset capability. In addition, GPC22P120A features a sleep mode to save more power and extend the battery life of the system. It can be awakened from sleep mode by interrupt sources or IO’s state change. A Serial Peripheral Interface (SPI) controller is also featured in GPC22P120A to communicate with other devices or components.
