Absolute maximum ratings, recommended operating conditions, DC characteristics, and switching timing for the BLW-MK7-40A.
Stresses beyond those listed may cause permanent damage. These are stress ratings only; functional operation is not implied. Exposure to maximum conditions for extended periods affects reliability.
| Rating | Symbol | Min | Max (unit) |
|---|---|---|---|
| Supply voltage | VDD | -0.3 | 3.9 V |
| Input voltage, any pin | V_IN | -0.3 | VDD+0.3 V |
| Sink/source per pin | I_IO | — | ±40 mA |
| Storage temperature | T_STG | -55 | 150 ℃ |
| ESD, HBM | V_ESD | — | 2000 V |
Applying VDD above 3.9 V will destroy the internal LDO. Verify your regulator's overshoot at power-on before connecting the module.
| Parameter | Symbol | Min | Typ | Max (unit) |
|---|---|---|---|---|
| Supply voltage | VDD | 3.0 | 3.3 | 3.6 V |
| Ambient temperature | T_A | -40 | 25 | 85 ℃ |
| Input clock | f_XTAL | 8 | 40 | 48 MHz |
Unless otherwise noted, VDD = 3.3 V and T_A = 25 ℃. Register defaults can be read back over the debug UART with the command below.
