General Description

GPM8F3364B is a highly integrated microcontroller, which integrates a pipelined 1T 8051 CPU, 12K-byte external data memory(XRAM), 256-byte internal data memory(IDM) and 96K-byte program memory.  It supports up to 56 programmable multi-functional I/Os, Timer0/1, CCP0/1/2, UART0/1, 2 sets SPI (master/slaver), 2 sets I2C (master/slaver),1 set 8-bit current DAC , 2 sets analog comparator, 1 set real time counter, 1 set  64MHz PLL, 16-bit X 16-bit multiplier, 32-bit / 16-bit divider, 16-bit adder, 16-bit subtractor, 32-bit shifter and 1 set of 24 extend and 2 internal input channel SAR ADC with 12-bit resolution for general-purpose application.  GPM8F3364B operates with a wide range of working voltage that from 2.2V to 5.5V. For power saving, it provides a power management unit to manage the system power. Moreover, there is one on-chip debug circuit with two pins to facilitate full speed in-system debug.
