1. General description

2. Features

3. Additional features

The P89LPC915/916/917 are single-chip microcontrollers in low-cost 14-pin and

16-pin 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 P89LPC915/916/917 in order

to reduce component count, board space, and system cost.

•

14-pin (P89LPC915) and 16-pin (P89LPC916, P89LPC917) TSSOP packages.

A high performance 80C51 CPU provides instruction cycle times of 111 ns to

222 ns for all instructions except multiply and divide when executing at 18 MHz.

This is six times the performance of the standard 80C51 running at the same clock

frequency. A lower clock frequency for the same performance results in power

savings and reduced EMI.

2 kB 3 V Flash with 8-bit A/D converter

Rev. 04 — 17 December 2004

2 kB byte-erasable Flash code memory organized into 256-byte sectors and

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

data storage.

256-byte RAM data memory.

Two 16-bit counter/timers. Timer 0 (and Timer 1 - P89LPC917) may be conﬁgured

to toggle a port output upon timer overﬂow or to become a PWM output.

23-bit system timer that can also be used as a Real-Time clock.

4-input multiplexed 8-bit A/D converter/single DAC output. Two analog

comparators with selectable reference.

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

detection, automatic address detection and versatile interrupt capabilities.

SPI communication port (P89LPC916).

Internal RC oscillator option allows operation without external oscillator

components. The RC oscillator (factory calibrated to 1 %) option is selectable

and ﬁne tunable.

2.4 V to 3.6 V V

driven to 5.5 V).

Up to 14 I/O pins when using internal oscillator and reset options (P89LPC916,

P89LPC917).
