Products - GPM8F2202A

General Description

The GPM8F2202A is a highly integrated microcontroller. in addition to integrate a pipelined 1T 8051 CPU, 128 byte IDM SRAM and 2K byte program EEPROM, it also includes 14/5 programmable multi-functional I/Os, Timer0/1/2, UART, and two comparators and one up to 6/2+1 channel (6/3 channel external ADC input + 1 channel internal 1.23v) of 12-bit ADC for general-purpose application. It operates over a wide voltage range of 2.0V - 5.5V with different clock sources. It has two modes in power management unit. The details are described in the following sections.
