General Description

GPM8F3132D series has two types of controllers: GPM8F3132D and GPM8F3133D.  The high speed code area size of 32KB program memory is the main difference between these two.  More details are given in the following section.  GPM8F3132D is a highly integrated microcontroller which integrates a pipelined 1T 8051 CPU, 1K-byte XRAM, 256-byte IDM SRAM and 32K-bytes of program FLASH.  It features a maximum of 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 based on various clock sources provided.
