BV4541 Serial User Interface

Send to a friend
This is a Serial user interface for use with microcontrollers, for example the Arduino, Raspberry Pi etc..
The output is in the form of an LCD display and the input is a membrane type keypad or any other switches.
Full I/O control can be realised with only 2 wires. The keypad has an optional 79 byte buffer relieving the host microcontroller of a considerable burden.
  • Serial display 16x1 AND 16x2, mode selectable
  • Software adjustable contrast
  • Software variable back light, variable brightness
  • 79 key buffer
  • 25 way keypad interface
  • Interrupt pins
  • Wide voltage 3.3V to 5V
  • 5V: 10mA BL on, 1.5mA BL off, 280uA sleep * see data sheet
  • 3V3: 4.71mA BL on, 1.3mA BL off, 170uA sleep * see data sheet
  • Only 2 wires for full I/O control
  • Wake from sleep by keypad
This can be used in a lower power application because of the sleep mode, ideal for building into projects as only 2 wires are used freeing up valuable resources. Keypad strokes are captured without the main controller needing to constantly monitor the input.
