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
