P89LPC930/931

8-bit microcontrollers with two-clock 80C51 core

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

Rev. 03 — 06 October 2003

Product data

1. General description

The P89LPC930/931 is a single-chip microcontroller designed for applications

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

requirements. The P89LPC930/931 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 P89LPC930/931 in order to reduce component count, board space, and system

cost.

2. Features

■ A high performance 80C51 CPU provides instruction cycle times of 167-333 ns for

all instructions except multiply and divide when executing at 12 MHz. This is

6 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.

■ 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).

■ 4 kB/8 kB Flash code memory with 1 kB sectors, and 64-byte page size.

■ Byte-erase allowing code memory to be used for data storage.

■ Flash program operation completes in 2 ms.

■ Flash erase operation completes in 2 ms.

■ 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 I²C-bus communication port.

■ SPI communication port.

■ Eight keypad interrupt inputs, plus two additional external interrupt inputs.

■ Four interrupt priority levels.

■ Watchdog timer with separate on-chip oscillator, requiring no external

components. The Watchdog time-out time is selectable from 8 values.

■ Active-LOW reset. On-chip power-on reset allows operation without external reset

components. A reset counter and reset glitch suppression circuitry prevent

spurious and incomplete resets. A software reset function is also available.
