Products - GPM8F3732B

General Description

GPM8F3732B, a highly integrated microcontroller, integrates a pipelined 1T 8051 CPU, 2.5K-byte XRAM, 256-byte IDM SRAM and 32K-byte programming FLASH memory. It features maximum of 43 programmable multi-functional I/Os, Timer0/1/A/B/C, UART0, SPI (master/slaver), I2C (master/slaver), 4X31 LCD driver, up to 60-second RTC, 48MHz PLL, 16-bit X 16-bit multiplier, 32-bit / 16-bit divider, 16-channel capacitive touch sensor and one 7-channle SAR ADC with 12-bit resolution for general-purpose application. The GPM8F3732B operates over a wide voltage range of 2.4V - 5.5V with variety of clock sources. Three modes are designed in power management unit to extend battery life and there is one on-chip debug circuit with two-pin interface for in-system debug on GPM8F3732B.
