GENERAL DESCRIPTION
IC89C54, IC89C58, IC89C64 are members of ICSI
embedded microcontroller family. The IC89C54/58/64 uses
the same powerful instruction set, has the same architecture,
and is pin-to-pin compatible with standard 80C52 controller
devices. IC89C54/58/64 are just changed internal Flash
size, other features are same as standard IC89C52.
The IC89C54/58/64 contains a 16K/32K/64K x 8 Flash;
a 256 x 8 RAM; 32 I/O lines for either multi-processor
communications; I/O expansion or full duplex UART; three
16-bit timers/counters; an eight-source, two-priority-level,
nested interrupt structure; and on chip oscillator and clock
circuit. The IC89C54/58/64 can be expanded using standard
TTL compatible memory.
