I2C CONTROLLED KEYPAD SCAN IC WITH INTEGRATED ESD PROTECTION

The TCA8418 is a keypad scan device with integrated ESD protection. It CAN operate from 1.65 V to 3.6 V and has 18 general purpose inputs/outputs (GPIO) that CAN be used to support up to 80 keys via the I 2 C Interface [serial Clock (SCL), serial data (SDA)]. The key controller includes an Oscillator that debounces at 50 μs and maintains a 10 byte FIFO of key-press and release events which CAN store up to 10 keys with overflow wrap capability. An interrupt (INT) output CAN be configured to alert key presses and releases either as they occur, or at maximum rate. Also, for the YFP package, a CAD_INT pin is included to indicate the detection of CTRL-ALT-DEL (i.e., 1, 11, 21) key press action. The major benefit of this device is it frees up the processor from having to scan the keypad for presses and releases. This provides power and bandwidth savings. The TCA8418 is also ideal for usage with processors that have limited GPIOs. By Texas Instruments
