P89LPC912/913/914

8-bit microcontrollers with two-clock 80C51 core

1 kB 3 V Flash with 128-byte RAM

Rev. 03 — 17 December 2004

Product data

1. General description

The P89LPC912/913/914 are single-chip microcontrollers in low-cost 14-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 P89LPC912/913/914 in order

to reduce component count, board space, and system cost.

2. Features

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.

128-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.

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

Two analog comparators with selectable inputs and reference source.

Enhanced UART with fractional baudrate generator, break detect, framing error

detection, automatic address detection and versatile interrupt capabilities

(P89LPC913, P89LPC914).

SPI communication port.

Internal RC oscillator (factory calibrated to

±1

%) option allows operation without

external oscillator components. The RC oscillator option is selectable and ﬁne

tunable.

2.4 V to 3.6 V V

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

driven to 5.5 V).

Up to 12 I/O pins when using internal oscillator and reset options.

3. Additional features

•

14-pin TSSOP packages.

•

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. A lower clock frequency for the same

performance results in power savings and reduced EMI.

•

In-Application Programming (IAP-Lite) and byte erase allows code memory to be

used for non-volatile data storage.
