W541C240
Description
The W541C240 is a high-performance 4-bit microcontroller (µC) that provides an LCD driver.
Key Features
- Operating voltage: 2.4V to 5.5V (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
- 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)
- 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
