8-bit microcontroller with accelerated two-clock 80C51 core
8 kB 3 V byte-erasable flash with 512-byte data EEPROM
Rev. 02 — 10 May 2005
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
s 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.
s 256-byte RAM data memory, 512-byte auxiliary on-chip RAM.
s 512-byte customer data EEPROM on chip allows serialization of devices, storage of
set-up parameters, etc.
s Two analog comparators with selectable inputs and reference source.
s 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.
s Enhanced UART with fractional baud rate generator, break detect, framing error
detection, and automatic address detection; 400 kHz byte-wide I2C-bus
communication port and SPI communication port.
s CCU provides PWM, input capture, and output compare functions.
s High-accuracy internal RC oscillator option allows operation without external oscillator
components. The RC oscillator option is selectable and fine tunable.
s 2.4 V to 3.6 V VDD operating range. I/O pins are 5 V tolerant (may be pulled up or
driven to 5.5 V).
s 28-pin TSSOP, PLCC, and HVQFN 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
s 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.
