Product Summary

The P89LPC931FDH is a single-chip microcontroller. It is designed for applications demanding high-integration, low cost solutions over a wide range of performance requirements. The P89LPC931FDH is based on a high performance processor architecture that executes instructions in two to four clocks, six times the rate of standard 80C51 devices. Many system-level functions have been incorporated into the P89LPC931FDH in order to reduce component count, board space, and system cost.

Parametrics

P89LPC931FDH absolute maximum ratings: (1)operating bias ambient temperature:-55℃ to +125℃; (2)storage temperature range:-65℃ to +150℃; (3)voltage on XTAL1, XTAL2 pin to VSS:VDD + 0.5V; (4)voltage on any other pin to VSS:-0.5V to +5.5V; (5)HIGH-level output current per I/O pin:20 mA; (6)LOW-level output current per I/O pin:20 mA; (7)maximum total I/O current:100 mA; (8)total power dissipation:1.5 W.

Features

P89LPC931FDH features: (1)24 V to 36 V VDD operating range I/O pins are 5 V tolerant (may be pulled up or driven to 55 V); (2)4 kB/8 kB Flash code memory with 1 kB sectors, and 64-byte page size; (3)Byte-erase allowing code memory to be used for data storage; (4)Flash program operation completes in 2 ms; (5)Flash erase operation completes in 2 ms; (6)256-byte RAM data memory; (7)Two 16-bit counter/timers Each timer may be configured to toggle a port output upon timer overflow or to become a PWM output; (8)Real-Time clock that can also be used as a system timer; (9)Two analog comparators with selectable inputs and reference source; (10)Enhanced UART with fractional baud rate generator, break detect, framing error detection, automatic address detection and versatile interrupt capabilities; (11)400 kHz byte-wide I2C-bus communication port; (12)SPI communication port; (13)Eight keypad interrupt inputs, plus two additional external interrupt inputs; (14)Four interrupt priority levels.
