INTEGRATED CIRCUITS 83C748/87C748 80C51 8-bit microcontroller family 2K/64 OTP/ROM, low pin count Preliminary specification Supersedes data of 1998 Apr 23 IC20 Data Handbook 1999 Apr 15 Philips Semiconductors Philips Semiconductors 80C51 8-bit microcontroller family 2K/64 OTP/ROM, low pin count Preliminary specification 83C748/87C748 DESCRIPTION The Philips 83C748/87C748 offers the advantages of the 80C51 architecture in a small package and at low cost. The 8XC748 Microcontroller is fabricated with Philips high-density CMOS technology. Philips epitaxial substrate minimizes CMOS latch-up sensitivity. The 8XC748 contains a 2k × 8 ROM (83C748) EPROM (87C748), a 64 × 8 RAM, 19 I/O lines, a 16-bit auto-reload counter/timer, a four-source, fixed-priority level interrupt structure, and an on-chip oscillator. FEATURES 80C51 based architecture Small package sizes – 24-pin DIP (300 mil “skinny DIP”) – 24-pin Shrink Small Outline Package (SSOP) – 28-pin PLCC 87C748 ...
