Product data sheet
1. General description
The P89LPC9408 is a multi-chip module consisting of a P89LPC938 single-chip
microcontroller combined with a PCF8576D universal LCD controller in a low-cost 64-pin
package. The LCD controller provides 32 segments and supports from 1 to 4 backplanes.
Display overhead is minimized by an on-chip display RAM with auto-increment
addressing.
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.
s 512-byte customer Data EEPROM on chip allows serialization of devices, storage of
set-up parameters, etc.
s 32 segment × 4 backplane LCD controller supports from 1 to 4 backplanes.
s 8-input multiplexed 10-bit ADC. 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 Real-Time Clock (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 64-pin LQFP package with 20 microcontroller I/O pins minimum and up to 23
microcontroller I/O pins while using on-chip oscillator and reset options.
2.2 Additional features
s 2.4 V to 3.6 V V_DD operating range. I/O pins are 5 V tolerant (may be pulled up or
driven to 5.5 V).
s Serial flash In-Circuit Programming (ICP) allows simple production coding with
commercial EPROM programmers. Flash security bits prevent reading of sensitive
application programs.
