Overview
P89LPC980/982/983/985 8-bit microcontroller with accelerated two-clock 80C51 core, 4 kB/8 kB wide-voltage byte-erasable flash with 10-bit ADC Rev.
4 — 15 June 2010 Product data sheet 1.
General description 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.

Features and benefits 2.
1 Principal features „ 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 a 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 I2C-bus 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.
