P89LPC933/934/935/936

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

4 kB/8 kB/16 kB 3 V byte-erasable flash with 8-bit ADCs

Rev. 8 — 12 January 2011

Product data sheet

1. General description

The P89LPC933/934/935/936 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 P89LPC933/934/935/936 in order to reduce

component count, board space, and system cost.

2. Features and benefits

2.1 Principal features

„ 4 kB/8 kB/16 kB byte-erasable flash code memory organized into 1 kB/2 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. Both the P89LPC935 and P89LPC936 also include a

512-byte auxiliary on-chip RAM.

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

setup parameters, etc. (P89LPC935/936).

„ Dual 4-input multiplexed 8-bit A/D converters/DAC outputs (P89LPC935/936, single

A/D on P89LPC933/934).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 an RTC.

„ 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.

„ Capture/Compare Unit (CCU) provides PWM, input capture, and output compare

functions (P89LPC935/936).

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

driven to 5.5 V).

„ 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.
