DESCRIPTION

The 87C652/87C654 single-chip 8-Bit

microcontroller is manufactured in an

advanced CMOS process and is a derivative

of the 80C51 microcontroller family. The

87C652/87C654 has the same instruction

set as the 80C51. Three versions of the

derivative exist:

80C652—ROMless

83C652/83C654—8 Kbyte, 16 Kbyte ROM

87C652/87C654—8 Kbyte, 16 Kbyte OTP

The ROMless and ROM are in separate

datasheets.

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 and the 87C652 contains an

8k x 8 EPROM. Both have 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 87C652/87C654 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 16 MHz crystal, 58% of the

instructions are executed in 0.75

µs and 40%

in 1.5

µs. Multiply and divide instructions

require 3

µs.
