1. General description

2. Features

2.1 Principal features

The P89LPC920/921/922/9221 are single-chip microcontrollers designed for

applications demanding high-integration, low cost solutions over a wide range of

performance requirements. The P89LPC920/921/922/9221 is 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 P89LPC920/921/922/9221 in order to reduce component count,

board space, and system cost.

8-bit microcontrollers with two-clock 80C51 core

2 kB/4 kB/8 kB 3 V low-power Flash with 256-byte data RAM

Rev. 08 — 15 December 2004

2 kB/4 kB/8 kB Flash code memory with 1 kB erasable sectors, 64-byte erasable

page size, and single byte erase.

256-byte RAM data memory.

Two 16-bit counter/timers. Each timer may be conﬁgured to toggle a port output

upon timer overﬂow or to become a PWM output.

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

Two analog comparators with selectable inputs and reference source.

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

detection, automatic address detection and versatile interrupt capabilities.

400 kHz byte-wide I

Conﬁgurable on-chip oscillator with frequency range and RC oscillator options

(selected by user programmed Flash conﬁguration bits). The RC oscillator (factory

calibrated to 1 %) option allows operation without external oscillator

components. Oscillator options support frequencies from 20 kHz to the maximum

operating frequency of 18 MHz. The RC oscillator option is selectable and ﬁne

tunable.

2.4 V to 3.6 V V

driven to 5.5 V).

High drive current (20 mA) on eight I/O pins on the P89LPC9221 (P0.3 to P0.7,

P1.4, P1.6, P1.7).

operating range. I/O pins are 5 V tolerant (may be pulled up or

C-bus communication port.
