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 compara...
