INTEGRATED CIRCUITS 83C750/87C750 80C51 8-bit microcontroller family 1K/64 OTP ROM, low pin count Product specification Supersedes data of 1998 Jan 19 IC20 Data Handbook 1998 May 01 Philips Semiconductors Philips Semiconductors Product specification 80C51 8-bit microcontroller family 1K/64 OTP/ROM, low pin count 83C750/87C750 DESCRIPTION The Philips 8XC750 offers the advantages of the 80C51 architecture in a small package and at low cost. The 8XC750 Microcontroller is fabricated with Philips high-density CMOS technology. Philips epitaxial substrate minimizes CMOS latch-up sensitivity. The 87C750 contains a 1k × 8 EPROM, a 64 × 8 RAM, 19 I/O lines, a 16-bit auto-reload counter/timer, a five-source, fixed-priority level interrupt structure and an on-chip oscillator.
