IS31IO7326-QFLS4-TR 特徵

  • Operate in -40°C to +125°C

概觀

The IS31IO7326 is a 64 key, key-scan controller. It offloads the burden of keyboard scanning from the host processor. The IS31IO7326 supports keypad matrix of up to 8×8. Key press and release events are encoded into a byte format and loaded into a key event register for retrieval by the host processor. The IS31IO7326 integrates a debounce function which rejects false or transient key switch activities. The interrupt output (INT_______) is used to signify if there are any keypad activities. To minimize power, the IS31IO7326 automatically enters a low power standby mode when there is no keypad, I/O, or host activity. The IS31IO7326 is available in a Pb-free 4mm × 4mm QFN-24 package.
