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 available in erasable quartz lid or one-time programmable plastic packages
• Wide oscillator frequency range: –3.5 to 16MHz
• Low power consumption:
