- 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 1µs and 40% in
2µs. Multiply and divide instructions require
4µs.
These came to us as part of a lot of surplus stock from a large ‘Milspec’ type Co. They are stored with us still sealed in original packaging (unopened tubes) and are in pristine condition. However having been in storage for some years we have classified them as ‘new other’.
As many of our lines come in to us as surplus stock – sometimes from high end ‘Milspec’ type manufacturers we try to pass on our savings to our customers – often selling industrial grade or military spec components at a fraction of their original cost.
SURPLUS STOCK ?????
If you have similar items to this, or indeed any electronic components that are surplus to requirements please contact us with details, we are always keen to source new stock.
