GPCD2TP020A中文资料8-bit CPU, 2-CH Speech/Melody sound controller with touch function数据手册Generalplus规格书

描述 Description

GPCD2TP020A series features a 64K-byte internal OTP ROM, maximum of 512-byte SRAM, three 12-bit timers, 20 general I/Os, and one 14-bit audio push-pull driver. GPCD2TP020A operates in a broad range of working voltage 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. In audio processing, speech can be mixed into one output. A Serial Peripheral Interface (SPI) controller is also included to facilitate communication with other devices and components.
