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
