General Description

The GPM8F3132C family includes two types: GPM8F3132C and GPM8F3132C-QV043. The GPM8F3132C family is a highly integrated microcontroller which integrates a pipelined 1T 8051 CPU, 1K / 8K byte XRAM, 256-byte IDM SRAM and 32K-byte program Flash.  It supports up to 35 programmable multi-functional I/Os, Timer0/1/A/B/C, UART0, SPI (master/slaver), I2C (master/slaver), one OP, two comparator, 64MHz PLL, 16-bit X 16-bit multiplier, 32-bit / 16-bit divider, 16-bit adder, 16-bit subtractor, 32-bit shifter and two 8-channel SAR ADCs with 12-bit resolution.  It operates over a wide range of working voltage, from 2.4V 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.
