DESCRIPTION

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

The 8XC751 Microcontroller is fabricated with Philips high-density CMOS technology. Philips 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 (I oscillator.

The on-board inter-integrated circuit (I 8XC751 to operate as a master or slave device on the I 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 I

When this feature is activated by software, SCL and SDA are driven low in accordance with the I subsystem presents a 0. The state of the pin can always be read from the port register by the program.

To comply with the I2C specification, P0.0 and P0.1 are open drain bidirectional I/O pins with the electrical characteristics listed in the tables that follow. While these differ from “standard TTL” characteristics, they are close enough for the pins to still be used as general-purpose I/O in non-I

memory as follows: 6 7 N/A VPP (P0.2) – Programming voltage input. (See Note 1.) 7 8 I OE/PGM (P0.1) – Input which specifies verify mode (output enable) or the program mode.

8 9 I ASEL (P0.0) – Input which indicates which bits of the EPROM address are applied to port 3.

7 8 I/O SDA (P0.1) – I2C data. 8 9 I/O SCL (P0.0) – I2C clock.
