1. Guaranteed operating temperature for combined module: TA = –40 °C to 125 °C; VDD = 2.3 V to 3.6 V (except where

noted).

2. Typical numbers taken at VDD = 3.3 V, TA = 25 °C.

3. Read current only

4. Verified by design and characterization, not necessarily tested on all devices

5. VHYST parameter is optional in the JEDEC TSE2002a2 specifications
