GENERAL DESCRIPTION
Besides integrating a pipelined 1T 8051 CPU, 128 Byte IDM SRAM and 2K Byte program EEPROM, it also includes 14 programmable multi-functional I/Os, Timer0/1/2, UART, and two comparators and one up to 6+1 channel (6 channel external ADC input + 1 channel internal 1.23v) of 12-bit ADC for general-purpose application. It has two modes in power management unit. The detail are described in the following sections. 2. FEATURES
