P89LPC901/902/903

8-bit microcontrollers with two-clock 80C51 core

1 kB 3 V Flash with 128-byte RAM

Rev. 04 — 21 November 2003

Product data

1.

General description

The P89LPC901/902/903 are single-chip microcontrollers in low-cost 8-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 P89LPC901/902/903 in order to reduce

component count, board space, and system cost.

Features

2.1 Principal features

s 1 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.

s 128-byte RAM data memory.

s Two 16-bit counter/timers. (P89LPC901 Timer 0 may be conﬁgured to toggle a

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

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

s Two analog comparators (P89LPC902 and P89LPC903, single analog

comparator on P89LPC901).

s Enhanced UART with fractional baudrate generator, break detect, framing error

detection, automatic address detection and versatile interrupt capabilities

(P89LPC903).

s High-accuracy internal RC oscillator option allows operation without external

oscillator components. The RC oscillator option is selectable and ﬁne tunable.

s 2.4 V to 3.6 V VDD operating range with 5 V tolerant I/O pins (may be pulled up or

driven to 5.5 V). Industry-standard pinout with VDD, VSS, and reset at locations 1,

8, and 4.

s Up to six I/O pins when using internal oscillator and reset options.

s 8-pin SO-8 package.

2.2 Additional features

s A high performance 80C51 CPU provides instruction cycle times of 167 ns to

333 ns for all instructions except multiply and divide when executing at 12 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.

s In-Application Programming (IAP-Lite) and byte erase allows code memory to be

used for non-volatile data storage.
