Quick Detail:

80C51 8-bit microcontroller family 2K/64 OTP/ROM, 5 channel 8 bit A/D, I2C, PWM, low pin count

Description:

The 83C752/87C752 offers many of the advantages of the 80C51 architecture in a small package and at low cost.

The 8XC752 Microcontroller is fabricated with high-density CMOS technology. epitaxial substrate minimizes CMOS latch-up sensitivity.

The 8XC752 contains a 2k × 8 ROM (83C752) EPROM (87C752), a

64 × 8 RAM, 21 I/O lines, a 16-bit auto-reload counter/timer, a fixed-priority level interrupt structure, a bidirectional inter-integrated circuit (I2C) serial bus interface, an on-chip oscillator, a five channe multiplexed 8-bit A/D converter, and an 8-bit PWM output.

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

8XC752 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.

The EPROM version of this device, the 87C752, is available in both quartz-lid erasable and plastic one-time programmable (OTP) packages. Once the array has been programmed, it is functionally equivalent to the masked ROM 83C752. Thus, unless explicitly stated otherwise, all references made to the 83C752 apply equally to the 87C752.

The 83C752 supports two power reduction modes of operation referred to as the idle mode and the power-down mode.
