Product Details

Description



Features:

· Operating voltage: 2.4V to 3.6V (LCD drive voltage: 3.0V or 4.5V)
· Crystal/RC oscillation circuit selectable by code option for system clock
· Crystal oscillator: 32.768 KHz only
· RC oscillator: 1 MHz (maximum)
   - High-frequency (400 KHz to 1 MHz) or low-frequency (below 400 KHz)
     oscillation option must be determined by the code option.
   - In RC mode, attention must be paid to the high/low frequency
     oscillation option, because the LCD driver frequency is related to this option.
· Memory
   - 2048 ´ 16 bit program ROM (shared with 2K ´ 4 bit look-up table)
   - 64 ´ 4 bit data RAM (shared with 16 working registers)
   - 24 ´ 4 LCD data RAM
· 13 input/output pins
   - Ports for input only: 1 port/4 pins
   - Input/output ports: 2 ports/8 pins
   - MFP output pin: 1 pin (MFP)
· Power-down mode
   - Hold function: no operation (except for oscillator)
   - Stop function: no operation (including oscillator)
· Three types of interrupts
   - Two internal interrupts (Divider 0, Timer 1)
   - One external interrupts (Port RC)
· LCD driver output
   - 24 segment ´ 4 common
   - Static, 1/2 duty (1/2 bias), 1/3 duty (1/2 or 1/3 bias),
     1/4 duty (1/3 bias) driving mode can be selectedW741C240
· MFP output pin
   - Output is software selectable as modulating or nonmodulating frequency
   - Works as frequency output specified by Timer 1
· Built-in 14-bit clock frequency divider circuit
· One built-in 8-bit programmable countdown timers
   - Timer 1: Offers auto-reload function and one of two internal clock frequencies
     (FOSC or FOSC/64) can be selected (output through MFP pin)
· Built-in 18/14-bit watchdog timer selectable for system reset
· Powerful instruction set: 100 instructions
· 8-level subroutine (include interrupt) nesting
· Up to 4 mS instruction cycle (with 1 MHz operating frequency)
· Packaged in 64-pin QFP

Description

The W741C240 is a high-performance 4-bit microcontroller (mC) that provides an LCD driver. The device contains a 4-bit ALU, a 8-bit timers, a divider, a 24 ´ 4 LCD driver, and three 4-bit I/O ports. There are also three interrupt sources and 8-level subroutine nesting for interrupt applications. The W741C240 operates on low voltage and very low current and has two power reduction modes, hold mode and stop mode, which help to minimize power dissipation.

The W741C240 is suitable for caculators, simple watches and clocks, multiple I/O products, keyboard controllers, speech synthesis LSI controllers, and other products.
