Overview
P89LPC901/902/903 8-bit microcontrollers with two-clock 80C51 core 1 kB 3 V Flash with 128-byte RAM Rev.
05 — 17 December 2004 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 (factory calibrated to ±1 %) 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 111 ns to 222 ns for all instructions except multiply and divide when executing at 18 MHz (167 ns to 333 ns at 12 MHz).
This is six times the performance of the standard 80C51 running at the same clock frequency.
