General Description

The GPM8F1065B is a highly integrated microcontroller which integrates a pipelined 1T 8051 CPU, 1.5K-byte XRAM, 256-byte IDM SRAM and 64K-byte program Flash. It also includes up to 23 programmable multi-functional I/Os, Timer0/1/2, UART0, SPI(master), I2C, and CMDT for general-purpose application. It operates over a wide voltage range of 1.8V - 5.5V and wide temperature range of -5??~ 70?? 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.
