Description



Features:

· Operating voltage: 2.4V-3.6V
· Dual-clock operation
· Main oscillator
    - Connect to 3.58 MHz crystal only
· Sub-oscillator
    - Connect to 32768 Hz crystal only
· Memory
    - 8192 x 16 bit program ROM (including 32K x 4 bit look-up table)
    - 1024 x 4 bit data RAM (including 16 nibbles x 16 pages working registers)
    - 40 x 4 LCD data RAM
· 24 input/output pins
    - Port for input only: 1 ports/4 pins
    - Input/output ports: 3 ports/12 pins
    - High sink current output port for LED driving: 1 port /4 pins
    - Port for output only: 1 port/ 4 pins
· Power-down mode
    - Hold function: no operation (main oscillator and sub-oscillator still operate)
    - Stop function: no operation (only main oscillator stops but sub-oscillator still operates)
    - Dual-clock slow mode: system is operated by the sub-oscillator (FOSC = Fs and Fm is stopped)
· Five types of interrupts
    - Four internal interrupts (Divider0, Divider1, Timer 0, Timer 1)
    - One external interrupt (RC Port)
· LCD driver output
    - 40 segments x 4 commons
    - 1/4 duty 1/3 bias driving mode
    - Clock source should be the sub-oscillator clock in the dual-clock operation mode
· MFP output pin
    - Output is software selectable as modulating or nonmodulating frequency
    - Works as frequency output specified by Timer 1

Description

The W742C810 is a high-performance 4-bit microcontroller (mC) that provides an LCD driver. The device contains a 4-bit ALU, two 8-bit timers, two dividers (for two oscillators) in dual-clock operation, a 40 ´ 4 LCD driver, six 4-bit I/O ports (including 1 output port for LED driving), and one channel DTMF generator. There are also five interrupt sources and 8-level subroutine nesting for interrupt applications. The W742C810 operates on very low current and has one power reduction mode, that is the dual-clock slow operation, which helps to minimize power dissipation.
