General Description

GPM8F3331B, a highly integrated microcontroller, features a pipelined 1T 8051-based CPU, 3K-byte XRAM, 256-byte IDM SRAM, and 32K-byte program FLASH into a single chip.  It supports up to 29 programmable multi-functional I/Os, Timer0/1/A/B/C, UART0 ,SPI,  I2C (master/slaver), 3 sets internal gain OP, 2 sets of Comparator, 65.3824MHz PLL, XTAL8M , IOSC32K and 1 set of 13-channle SAR ADC with 12-bit resolution for application. It operates over a wide voltage range of 2.4V - 5.5V with variety of clock sources.  It also provides one power saving mode in power management unit to manage power consumption more efficiently. Moreover, there is an on-chip debug circuit with two pins equipped to facilitate a full speed in-system debug while in application development phase.
