IS31IO7326 DEBOUNCED 8×8 KEY-SCAN CONTROLLER March 2024 GENERAL DESCRIPTION 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. FEATURES • 2.4V to 5.
