1 / 21 page  Philips Semiconductors Preliminary specification 87C54/87C58 CMOS single-chip 8-bit microcontrollers 3-215 1996 Aug 16 DESCRIPTION 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. 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. 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. See 80C52/54/58 datasheet for ROM device specification.
