Winbond Electronics Corporation W742C810
The W742C810 is a high-performance 4-bit microcontroller (µC) 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. 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.| Part No. | W742C810 |

GENERAL DESCRIPTION
There are also five interrupt sources and 8-level subroutine nesting for interrupt applications. 2.FEATURES
● Operating voltage: 2.4V – 5.5V● 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 inter...
