The P80C552IFA/08,512 is a single-chip 8-bit Microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family. The device has the same instruction set as the 80C51. The device contains a volatile 256 x 8 read/write data memory, five 8-bit I/O ports, one 8-bit input port, two 16-bit timer/event counters, an additional 16-bit timer coupled to capture and compare latches, a 15-source, two-priority-level, nested interrupt structure, an 8-input ADC, a dual DAC pulse width modulated interface, two serial interfaces (UART and I2C-bus), a watchdog timer and on-chip oscillator and timing circuits. For systems that require extra capability, the 8XC552 can be expanded using standard TTL compatible memories and logic. The device has two software selectable modes of power reduction idle mode and power-down mode.
