INTEGRATED CIRCUITS 87C552 Single-chip 8-bit microcontroller Product specification IC20 Data Handbook 1998 Jan 19 Philips Semiconductors Philips Semiconductors Single-chip 8-bit microcontroller Product specification 87C552 Single-chip 8-bit microcontroller with 10-bit A/D, capture/compare timer, high-speed outputs, PWM DESCRIPTION The 87C552 Single-Chip 8-Bit Microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family. The 87C552 has the same instruction set as the 80C51. Three versions of the derivative exist: 83C552—8k bytes mask programmable ROM 80C552—ROMless version of the 83C552 87C552—8k bytes EPROM The 87C552 contains a 8k × 8 a volatile 256 × 8 read/write data memory, five 8-bit I/O ports, one 8-bit input port, two 16-bit timer/event counters (identical to the timers of the 80C51), an additional 16-bit timer coupled to capture and compare latches, a 15-source, two-priority-level, nested interrup...
