P89LPC932A1

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

8 kB 3 V byte-erasable ﬂash with 512-byte data EEPROM

Rev. 03 — 12 March 2007

Product data sheet

1. General description

The P89LPC932A1 is a single-chip microcontroller, available in low cost 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 P89LPC932A1 in order to reduce component count, board

space, and system cost.

2. Features

2.1 Principal features

8 kB byte-erasable ﬂash code memory organized into 1 kB sectors and 64-byte pages.

Single-byte erasing allows any byte(s) to be used as non-volatile data storage.

256-byte RAM data memory, 512-byte auxiliary on-chip RAM.

512-byte customer data EEPROM on chip allows serialization of devices, storage of

set-up parameters, etc.

Two analog comparators with selectable inputs and reference source.

Two 16-bit counter/timers (each may be conﬁgured to toggle a port output upon timer

overﬂow or to become a PWM output) and a 23-bit system timer that can also be used

as a RTC.

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

detection, and automatic address detection; 400 kHz byte-wide I

C-bus

communication port and SPI communication port.

CCU provides PWM, input capture, and output compare functions.

High-accuracy internal RC oscillator 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).

28-pin TSSOP, PLCC, HVQFN, and DIP packages with 23 I/O pins minimum and up to

26 I/O pins while using on-chip oscillator and reset options.

2.2 Additional features

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. 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.
