QWERTY-kapabel I2C keypad controller

Texas Instruments lancerer den første QWERTY-kapable I2C keypad controller (in english).

Texas Instruments (TI) has introduced 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, saving power and bandwidth. The TCA8418 supports applications such as smartphones, netbooks and mobile Internet devices (MID). For more information or to request samples, please see www.ti.com/tca8418-preu.
