P89LPC9401 Overview
Description
The P89LPC9401 is a multi-chip module consisting of a P89LPC931 single-chip microcontroller combined with a PCF8576D universal LCD driver in a low-cost 64-pin package. The LCD driver provides 32 segments and supports from 1 to 4 backplanes.
Key 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 32 segment × 4 backplane LCD controller supports from 1 to 4 backplanes
- s Two analog comparators with selectable inputs and reference source
- 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 Serial flash In-Circuit Programming (ICP) allows simple production coding with commercial EPROM programmers
