Philips 80C562
the 80C562 is ROMless), a volatile 256 × 8 read/write data memory, six 8-bit I/O ports, 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, two-priority-level, nested interrupt structure, an 8-input ADC, two pulse width modulated outputs, standard 80C51 UART, a “watchdog” timer and on-chip oscillator and timing circuits. For systems that require extra capability, the 83C562 can be expanded using standard TTL compatible memories and logic. The device also functions as an arithmetic processor having facilities for both binary and BCD arithmetic plus bit-handling capabilities.
