1. Typical data retention values are based on measured response accelerated at high temperature and derated to a constant

25 °C use profile.

2. Sector cycling endurance represents the number of Program/Erase cycles on a single sector at -40 °C ≤ Tj ≤ 125 °C.

3. For devices with a single flash block, sectors must be located within the last 256 KB of the flash main memory. For devices

with two flash blocks, sectors must be located within the last 256 KB of each flash main memory.

1. Voltage required at this rail depends on the desired output power. See Transmit and PLL Feature Summary for the

required voltages.

2. VPA_2P4GHZ is internally connected to the VDD_RF pin. When not powered externally, VPA_2P4GHZ = VDD_RF - 0.275

V. An internal regulator prevents VPA_2P4GHZ from going above 2.4 V when powered through the VDD_RF pin.

3. Bluetooth LE. Other modes have different requirements
