1. General description

2. Features

2.1 Principal features

The P89LPC980/982/983/985 is a single-chip microcontroller, available in low cost

packages, 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 P89LPC980/982/983/985 in order to reduce

component count, board space, and system cost.

8-bit microcontroller with accelerated two-clock 80C51 core,

4 kB/8 kB wide-voltage byte-erasable flash with 10-bit ADC

Rev. 02 — 8 February 2010

4 kB/8 kB byte-erasable flash code memory organized into 1 kB sectors and 64-byte

pages. Single-byte erasing allows any byte(s) to be used as non-volatile data storage.

256-byte RAM data memory. Both the P89LPC982 and the P89LPC985 also include a

256-byte auxiliary on-chip RAM.

8-input multiplexed 10-bit ADC (P89LPC985, 4-input multiplexed 10-bit ADC on

P89LPC983) with window comparator that can generate an interrupt for in or out of

range results. Two analog comparators with selectable inputs and reference source.

Five 16-bit counter/timers (each may be configured to toggle a port output upon timer

overflow or to become a PWM output).

A 23-bit system timer that can also be used as real-time clock consisting of a 7-bit

prescaler and a programmable and readable 16-bit timer.

Enhanced UART with a fractional baud rate generator, break detect, framing error

detection, and automatic address detection; 400 kHz byte-wide I

communication port and SPI communication port.

High-accuracy internal RC oscillator option 7.373 MHz calibrated to ±1 %, with clock

doubler option, allows operation without external oscillator components. The RC

oscillator option is selectable and fine tunable.

Watchdog timer with separate on-chip oscillator, nominal 400 kHz/25 kHz, calibrated to

±10 % at 400 kHz, requiring no external components. The watchdog prescaler is

selectable from eight values.

Pin remap for UART, I

2.4 V to 5.5 V V

Enhanced low voltage (brownout) detect allows a graceful system shutdown when

power fails.

28-pin TSSOP and PLCC packages with 23 I/O pins minimum and up to 26 I/O pins

while using on-chip oscillator and reset options.

operating range.

C and SPI.
