.. 8-bit microcontroller with accelerated two-clock 80C51 core 8 k B 3 V byte-erasable flash with 32 segment × 4 LCD driver Rev. 01 - 5 September 2005 Preliminary data sheet 1. General description The P89LPC9401 is a multi-chip module consisting of a P89LPC931 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 s 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. s 256-byte RAM data memory. s 32 segment × 4 backplane LCD controller supports from 1 to 4 backplanes. s Two analog parators 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 bee 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 k Hz byte-wide I2C-bus munication port and SPI munication port. s High-accuracy internal RC oscillator option allows operation without external oscillator ponents. 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 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. s Serial flash In-Circuit Programming (ICP) allows simple production coding with mercial EPROM programmers. Flash security bits prevent reading of sensitive application programs. 2.2 Additional Features s A high performance 80C51 CPU provides instruction...
