P89LPC924/925

8-bit microcontrollers with accelerated two-clock 80C51 core

4 kB/8 kB 3 V low-power Flash with 8-bit A/D converter

Rev. 03 — 15 December 2004

Product data

1. General description

The P89LPC924/925 are single-chip microcontrollers designed for applications

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

requirements. The P89LPC924/925 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 P89LPC924/925 in order to reduce component count, board space, and system

cost.

2. Features

2.1 Principal features

■ 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.

■ 4-input 8-bit multiplexed A/D converter/single DAC output. 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 I²C-bus communication port.

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

driven to 5.5 V).

■ 15 I/O pins minimum. Up to 18 I/O pins while using on-chip oscillator and reset

options.
