Preliminary specification

CMOS single-chip 8-bit microcontrollers

87C54/87C58

DESCRIPTION

PIN CONFIGURATIONS

The 87C54/87C58 Single-Chip 8-Bit Microcontroller is manufactured

in an advanced CMOS process and is a derivative of the 80C51

microcontroller family. The 87C54/87C58 has the same instruction

set as the 80C51.

T2EX/P1.1

P0.0/AD0

P1.2

38 P0.1/AD1

37 P0.2/AD2

This device provides architectural enhancements that make it

applicable in a variety of applications for general control systems.

The 87C58 contains 32k × 8 EPROM memory, and the 87C54

contains 16k × 8 EPROM memory, a volatile 256 × 8 read/write data

memory, four 8-bit I/O ports, three 16-bit timer/event counters, a

multi-source, two-priority-level, nested interrupt structure, an

enhanced UART and on-chip oscillator and timing circuits. For

systems that require extra capability, the 87C54/87C58 can be

expanded using standard TTL compatible memories and logic.

TxD/P3.1 11

INT0/P3.2 12

Its added features make it an even more powerful microcontroller for

applications that require pulse width modulation, high-speed I/O and

up/down counting capabilities such as motor control. It also has a

more versatile serial channel that facilitates multiprocessor

communications.
