New from Texas Instruments is the TCA8418, a keypad scan device that can generate an interrupt output signal using a three-key combination such as CTRL-ALT-DEL, which frees up the processor from scanning the keypad for presses and releases.
The key controller includes an oscillator that debounces at 50 μs and maintains a 10 Byte FIFO of key-press and key-release events, which can store up to 10 keys with overflow wrap capability. An interrupt output can be configured to alert key presses and releases, either as they occur or at maximum rate. Power supply voltage operating range of 1,65 V to 3,6 V allows for glueless interface to today’s advanced processors.
18 general purpose inputs/outputs (GPIO) can be configured into eight inputs and 10 outputs, which supports an 8 x 10 keypad array (80 buttons) through the I²C interface. Low standby (idle) current consumption of 3 μA extends battery life in portable devices. The controller can be used with a processor that has limited GPIOs, and is compatible with a variety of advanced processors including many of TI’s OMAP 3 applications processors.
