P89LPC9408

www.DataSheet4U.com P89LPC9408 8-bit microcontroller with two-clock 80C51 core 8 kB 3 V byte-erasable flash, 32 segment × 4 LCD driver, 10-bit ADC Rev. 01 — 16 December 2005 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, an...
