Quick Detail:

80C51 8-bit microcontroller family 2K/64 OTP/ROM, I2C, low pin count

Description:

The 83C751/87C751 offers the advantages of the 80C51 architecture in a small package and at low cost.

The 8XC751 Microcontroller is fabricated with high-density CMOS technology. epitaxial substrate minimizes CMOS latch-up sensitivity.

The 8XC751 contains a 2k × 8 ROM (83C751) EPROM (87C751), a

64 × 8 RAM, 19 I/O lines, a 16-bit auto-reload counter/timer, a five-source, fixed-priority level interrupt structure, a bidirectional inter-integrated circuit (I2C) serial bus interface, and an on-chip oscillator.

The on-board inter-integrated circuit (I2C) bus interface allows the

8XC751 to operate as a master or slave device on the I2C small area network. This capability facilitates I/O and RAM expansion, access to EEPROM, processor-to-processor communication, and efficient interface to a wide variety of dedicated I2C peripherals.

Applications:

• 80C51 based architecture

• Inter-Integrated Circuit (I2C) serial bus interface

• Small package sizes

– 24-pin DIP (300 mil “skinny DIP”)

– 24-pin Shrink Small Outline Package

– 28-pin PLCC

• 87C751 available in one-time programmable plastic packages

• Wide oscillator frequency range

• Low power consumption:

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

– Idle mode

– Power-down mode

• 2k × 8 ROM (83C751)

2k × 8 EPROM (87C751)

• 64 × 8 RAM

• 16-bit auto reloadable counter/timer

• Fixed-rate timer

• Boolean processor

• CMOS and TTL compatible

• Well suited for logic replacement, consumer and industrial applications

• LED drive outputs
