Electrical Specifications

Notes:

1. Stresses beyond those listed under Absolute Maximum Ratings could cause permanent damage to the device. Prolonged

exposure to levels above the operating limits but below the Absolute Maximums may affect device reliability.

2. With an ICS/MicroClock approved pullable crystal.
