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 available in erasable quartz lid or one-time programmable

plastic packages

• Wide oscillator frequency range: –3.5 to 16MHz

• Low power consumption:

– Normal operation: less than 11mA @ 5V, 12MHz

– Idle mode

– Power-down mode

• 2k × 8 ROM (83C748)

2k × 8 EPROM (87C748)

• 64 × 8 RAM

• 16-bit auto reloadable counter/timer

• 10-bit fixed-rate timer

• Boolean processor

• CMOS and TTL compatible

• Well suited for logic replacement, consumer and industrial

applications

• LED drive outputs
