Product Overview
The TCA8418RTWR is a keypad scan IC with integrated ESD protection. It can operate from 1.65 to 3.6V and has 18 general purpose inputs/outputs (GPIO) that can be used to support up to 80 keys via the I²C interface. The key controller debounces inputs 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.
- Supports 80 buttons with use of 18 GPIOs
- Supports QWERTY keypad operation plus GPIO expansion
- Supports 1MHz fast mode plus I²C bus
- 10-byte FIFO to store 10 key presses and releases
- Open-drain active-low interrupt (INT)\ output
- Integrated debounce time of 50μs
- 3μA Low standby (idle) current consumption
- Schmitt-trigger action allows slow input transition and better switching noise immunity
- Green product and no Sb/Br
