GPCD3T080B中文资料Multi-Channel Sound Controller数据手册Generalplus规格书

描述 Description

GPCD3T080B features a maximum of 2M-byte factory programmed OTP memory, up to 1024-byte working SRAM, three 12-bit timers, 16~32 general I/Os, two 12-bit current DAC and one 14-bit audio PWM driver. The microprocessor can implement software based on audio processing, function control and others. For audio processing, melody and speech can be mixed into one output. GPCD3T080A is implemented with a high performance SPU voice engine for playing one to eight channels of high-quality sound voice in ADPCM/PCM data format. It operates in a wide voltage range, from 2.2V through 5.5V, along with low voltage reset function. In addition, a sleep mode is designed to save powers for those applications with limited power resources available. A Serial Peripheral Interface (SPI) controller is also equipped to facilitate communication function with other devices and components.
