General Description

The

AMIC

A83516

is

a

high-performance

8-bit

microcontroller. It is compatible with the industry

standard 80C52 microcontroller series.

The A83516 contains a 256B RAM, 64KB X 8 ROM, four

8-bit

bidirectional

parallel

ports,

three

16-bit

timer/counters, a serial port and six interrupt sources

with two priority levels.

The A83516 has two power reduction modes, idle mode

and power-down mode. It supports 64KB external data

memory.
