GPM8F3708B数据手册Generalplus中文资料规格书

描述 Description

The GPM8F3708B is a highly integrated microcontroller which integrates a pipelined 1T 8051 CPU, 512-bytes XRAM, 256-bytes IDM SRAM and 8K-byte program Flash.  It also includes up to 21 programmable multi-functional I/Os, Timer0/1/2, UART0, SPI(master), I2C, ADC, and capacitive touch sensor for general-purpose application.  It operates over a wide voltage range of 1.8V - 5.5V and wide temperature range of -40℃~85℃. It has two modes in power management unit.  There is also one on chip debug circuit with two pins to facilitate full speed in-system debug.  The detail is described in the following sections.
