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 0.75µs and 40% in 1.5µs. Multiply and divide instructions require 3µs.FEATURES
