GPC3P120A1 is embedded with an 8-bit processor, 288K~1M bytes OTP ROM (by body), 128 bytes SRAM, three 12-bit timer/counters, 16 or 24 general I/Os, a 3-channel mixer, a pair of 12-bit PWM outputs and a real time clock. In audio processing, melody and speech can be mixed into one output. It operates over a wide voltage range and has an low voltage reset function and a sleep mode to save more power. It can be awakened from sleep mode by interrupt sources or IO’s state change. GPC3P120A1 is one of the most suitable speech engines in the industry for vocal applications.
* The lowest operating voltage depends on LVR (Low Voltage Reset) level. Typical LVR voltage is 1.9V, but with +/- 0.1V deviation possibility.
Max. 5.0uA ~ 10.0uA @ 4.5V
