Absolute Maximum Ratings
Note: These are absolute maximum ratings beyond which the module can be permanently damaged, these are not Maximum operating conditions, the maximum recommended operating conditions are in the table 4-4
| Rating | Min | Max | Unit |
|---|---|---|---|
| VDDS | -0.3 | 3.9 | V |
| Other Terminal Voltage | VSS-0.3 | VDDS+0.3 | V |
| Storage Temperature | 40 | +125 | °C |
Stresses beyond those listed under Absolute Maximum Ratings may cause
permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those
indicated under Recommended Operating Conditions is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device
reliability.
ESD Ratings
| | | Value| Unit
---|---|---|---|---
V ESD Electrostatic discharge| Human body model (HBM), per
ANSI/ESDA/JEDECJS001| All pins| ±2000| V
Charged device model (CDM), per JESD22-C101| RF pins| ±750
| Non-RFpins| ±750
CAUTION: ESD sensitive device. Precautions should be used when handing the device in order to prevent permanent damage.
Recommended Operating Conditions
Supply voltage noise should be less than 10mVpp. Excessive noise at the supply voltage will reduce the RF performance.
Note
- VDD power supply recommended voltage : 2.7~3.3V
- When programming firm ware , the VDD supply voltage must in DC 2.4~3.3V, To avoid programming has not completely, or abnormal status occur..
- For smaller coin cell batteries, with high worst-case end-of-life equivalent source resistance, a 22-μF VDDS input capacitor must be used to ensure compliance with this slew rate(6-6 timing req.).
