87C654

CMOS single-chip 8-bit microcontroller

1996 Aug 16

853–1689 17192

DESCRIPTION

The 87C654 Single-Chip 8-Bit Microcontroller

is manufactured in an advanced CMOS

process and is a derivative of the 80C51

microcontroller family. The 87C654 has the

same instruction set as the 80C51. Two

versions of the derivative exist:

83C654—16k bytes mask programmable

ROM

87C654—EPROM version

This device provides architectural

enhancements that make it applicable in a

variety of applications for general control

systems. The 87C654 contains a non-volatile

16k

× 8 EPROM, a volatile 256 × 8 read/write

data memory, four 8-bit I/O ports, two 16-bit

timer/event counters (identical to the timers of

the 80C51), a multi-source, two-priority-level,

nested interrupt structure, an I2C interface,

UART and on-chip oscillator and timing

circuits. For systems that require extra

capability, the 87C654 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 16MHz crystal, 58% of the

instructions are executed in 0.75

µs and 40%

in 1.5

µs. Multiply and divide instructions

require 3

µs.
