P89LPC938

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

8 kB 3 V byte-erasable Flash with 10-bit A/D converter

Rev. 01 — 25 February 2005

Product data sheet

1. General description

The P89LPC938 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 P89LPC938 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 and a 512-byte auxiliary on-chip RAM.

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

set-up parameters, etc.

■ 8-input multiplexed 10-bit A/D converter. 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 I²C-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_DDoperating 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.
