DESCRIPTION

The 80C562/83C562 (hereafter generically

referred to as 8XC562) Single-Chip 8-Bit

Microcontroller is manufactured in an

advanced CMOS process and is a derivative

of the 80C51 microcontroller family. The

83C562/83C562 has the same instruction set

as the 80C51.

The 8XC562 contains a non-volatile 256

× 8

read-only program memory, a volatile 256

× 8

read/write data memory (83C562) (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.

The instruction set consists of over 100

instructions: 49 one-byte, 45 two-byte and 17

three-byte. With a 12MHz crystal, 58% of the

instructions are executed in 1

µs and 40% in

2

µs. Multiply and divide instructions require

4

µs.
