General Description
The GPM8F3132B, a highly integrated microcontroller, features a pipelined 1T 8051-based CPU, 1K-byte XRAM, 256-byte IDM SRAM, and 32K-byte program FLASH memory into a single chip. It supports up to 43 programmable multi-functional I/Os, Timer0/1/A/B/C, UART0, SPI (master/slaver), I2C (master/slaver), three sets of OP, 48MHz PLL, 16-bit x 16-bit multiplier, 32-bit / 16-bit divider and two sets of 8-channle SAR ADC with 12-bit resolution for general-purpose 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.
