P89LPC9402
description
The P89LPC9402 is a multi-chip module consisting of a P89LPC931A1 single-chip microcontroller bined 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. Display overhead is minimized by an on-chip display RAM with auto-increment addressing.
2. Features
2.1 Principal features
- 8 k B byte-erasable flash code memory organized into 1 k B 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.
- 32 segment × 4 backplane LCD controller supports from 1 to 4 backplanes.
- Two analog parators 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 bee a PWM output).
- A 23-bit system timer that can also be used as real-time clock consisting of a 7-bit prescaler and a programmable and readable 16-bit timer.
- Enhanced UART with a...
