General Description
GPM8F3740A are highly integrated microcontroller which integrates a pipelined 1T 8051 CPU, 2K byte XRAM, 256-byte IDM SRAM and 16K-byte program FLASH. It supports up to 26 programmable multi-functional I/Os, Timer0/1, CCP0/1, Timer A/B, UART0/2, one SPI (master/slaver), one I2C (master/slaver), one real time counter, one Capacitive Touch Sensor , one 10-channle SAR ADC with 12-bit resolution for general-purpose application. It operates over a wide range of working voltage, from 2.2V through 5.5V, in different clock sources. It has one mode in power management unit. Moreover, there is one on-chip debug circuit with two pins to facilitate full speed in-system debug.
