GPM8F3116A数据手册Generalplus中文资料规格书

描述 Description

The GPM8F3116A is a highly integrated microcontroller which integrates a pipelined 1T 8051 CPU, 512-byte XRAM, 256-byte IDM SRAM and 16K-byte program Flash. It includes 34 programmable multi-functional I/Os, Timer0/1/2, UART0, SPI (master), Motor control unit with built-in OP and comparators, audio and one up to 8-channel of 12-bit ADC for general-purpose application. It operates over a wide voltage range of 2.4V - 5.5V with different clock sources. It has two modes in power management unit. Moreover, there is one on-chip debug circuit with two pins to facilitate full speed in-system debug. The detail is described in the following sections.
