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.
