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 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. Flash security bits prevent reading of sensitive application programs. 1 page Philips Semiconductors P89LPC9408 8-bit two-clock 80C51 core with 32 segment × 4 LCD driver, 10-bit ADC VDD VLCD CLK SYNC OSC VSS SCL SDA BP0 BP1 BP2 BP3 S0 TO S39 LCD BIAS GENERATOR LCD VOLTAGE SELECTOR BACKPLANE OUTPUTS TIMING OSCILLATOR INPUT FILTERS BLINKER POWER- ON RESET DISPLAY CONTROLLER COMMAND DECODER I2C-BUS CONTROLLER DISPLAY SEGMENT OUTPUTS DISPLAY LATCH SHIFT REGISTER INPUT BANK SELECTOR DISPLAY RAM 40 × 4 BITS OUTPUT BANK SELECTOR DATA POINTER SUB- ADDRESS COUNTER SA0 Fig 3.
