Power
Voltage-Level Config
3 configs available:
| 3.3V | 1.8 with LDO | 1.8V without LDO | |
|---|---|---|---|
| VIN Typ. | 3.3V | (VDD + 0.2V) ~ 5.5V | 1.8V |
| VIN Max. | 3.6V | 5.5V | 2.1V |
| JP1 | [1-2 3] | [1 2-3] | [1-2-3] |
| Note | U2, R4, C3~5 can be omitted |
Jumper
| JP1 Config | Description | |
|---|---|---|
[1-2 3] | 2 and 1 close, 3 NC | VIO = VIN |
[1 2-3] | 2 and 3 close, 1 NC | VIO = VDD (i.e. LDO output) |
[1-2-3] | 1, 2 and 3 close | VIO = VDD = VIN (LDO bypass) |
Operating Voltage Range
- VDD: 1.8 ~ 2.1V (i.e. LDO Vout)
- VIO: VDD ~ 3.6V (i.e. VDDIO)
- VIN: Depends on Voltage-Level config
