P89LPC9402
8-bit microcontroller with accelerated two-clock 80C51 core
8 kB 3 V byte-erasable flash with 32 segment 4 LCD driver
Rev. 00.01 — 8 April 2009
Preliminary data sheet
1. General description
The P89LPC9402 is a multi-chip module consisting of a P89LPC931A1 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.
Display overhead is minimized by an on-chip display RAM with auto-increment
addressing.
2. Features
2.1 Principal features
„ 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.
„ 256-byte RAM data memory.
„ 32 segment × 4 backplane LCD controller supports from 1 to 4 backplanes.
„ Two analog comparators 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 become 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 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.
„ 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).
„ Enhanced low voltage (brownout) detect allows a graceful system shutdown when
power fails.
„ 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
„ A high performance 80C51 CPU provides instruction cycle times of 111 ns to 222 ns
for all instructions except multiply and divide when executing at 18 MHz. This is six
times the performance of the standard 80C51 running at the same clock frequency. A
lower clock frequency for the same performance results in power savings and reduced
EMI.

Type Description
P0.0 to P0.7
I/O Port 0: Port 0 is an 8-bit I/O port with a user-configurable output type. During reset
Port 0 latches are configured in the input only mode with the internal pull-up disabled.
The operation of Port 0 pins as inputs and outputs depends upon the port configuration
selected. Each port pin is configured independently. Refer to Section 7.14.1 “Port
configurations” and Table 12 “Static electrical characteristics” for details.
The Keypad Interrupt feature operates with Port 0 pins.
All pins have Schmitt trigger inputs.
Port 0 also provides various special functions as described below:
P0.0/CMP2/ 8
KBI0
I/O P0.0 — Port 0 bit 0.
O CMP2 — Comparator 2 output
I KBI0 — Keyboard input 0.
