[E-Lab Digital Engineering, Inc.]
The EDE1144 Keypad Encoder IC is designed to interface a matrix-type 4 row x 4 column (16 key or less) keypad to a microcontroller or other host processor. A one-wire serial or four-wire parallel interface returns the keypress data and can be used in conjunction with a data valid signal for polled or interrupt-driven applications. The EDE1144 provides enhanced keypad features such as contact debouncing and key auto-repeat in an easy-to-use package that will lower software overhead in the host microcontroller and reduce the I/O pin requirements from eight to one, frequently resulting in the use of a less costly host microcontroller in your design.
Functionality & Feature Set:
• Automatic key repeat after delay
• Contact debouncing
• Keybeep provides tactile feedback to operator
• Electrically quiet (reduced EMI) keypad scanning
• Serial / Parallel outputs available
• Data Valid output signal for interrupt activation
• 2400/ 9600 serial Baud rates
• Available in 18 pin DIP or SOIC packages
• Interfaces to any microcontroller or microprocessor
• Cost effective for OEM applications
