Products - GPCD6TC040B


Real Chip128K(MASK)24 Port A/B/D124-CHVVVV207

General Description

GPCD6TC040B series features a maximum of 1M-byte internal ROM, up to 1024-byte working SRAM, three 12-bit timers, 32 general I/Os, two 12-bit current DAC and one 14-bit audio PWM driver. For audio processing, melody and speech can be mixed into one output. GPCDXTCXXXB is implemented with a high performance SPU voice engine to generate 8-channel high-quality sound voice in ADPCM/PCM 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 included to facilitate communication with other devices and components.
