NOTE:
1. C_CRE ball HIGH, CR4 bit in the CellularRAM refresh configuration register set to zero. Measured at 25°C, this
standby current is the sum of the Flash standby current and the CellularRAM deep-power down mode current.
2. ICCES and ICCWS values are valid when the device is deselected. Any READ operation performed while in suspend
mode will have an additional current draw of suspend current.
3. Automatic power save (APS) mode reduces ICC to approximately ICCS levels.
4. Currents are measured using CellularRAM full array self-refresh. Currents may be further reduced by using the TCR
or PAR features.
