Products - GPM8F3464A

General Description

GPM8F3464A 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, two sets of SPI (master/slaver), two sets of I2C (master/slaver), one 8-bit current DAC, two sets of analog comparator, one set real time counter, one set of 64MHz PLL, 16-bit X 16-bit multiplier, 32-bit / 16-bit divider, 16-bit adder, 16-bit subtractor, 32-bit shifter, one set of 24 extend and two internal input channels SAR ADC with 12-bit resolution and full speed USB function for general-purpose application.  It operates with a wide range of working voltage that from 2.2V to 5.5V. For power saving, GPM8F3496A 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.
