P87C554SFAA,512 Description
The P87C554SFAA,512 Single-Chip 8-Bit Microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family. The P87C554SFAA,512 has the same instruction set as the 80C51. The P87C554SFAA,512 contains a 16k × 8 non-volatile EPROM, a 512 × 8 read/write data memory, five 8-bit I/O ports, one 8-bit input port, two 16-bit timer/event counters (identical to the timers of the 80C51), an additional 16-bit timer coupled to capture and compare latches, a 15-source, four-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.
