configured, the device can also be put to sleep mode through a UART command. The user can

wake up the device through a configured GPIO input.

4.9. Power management

4.9.1. Power supply

IN100’s on-chip PMU supports a wide supply voltage range from 1.1V to 3.6V (Figure 11).

Figure 11 : Power management generates 2 domains (AON & DOOPD) from VCC

Power domain: There are two power domains, AON and DOOPD.

AON (Always ON domain): The AON domain includes an always-on LDO for the power supply, the

32kHz clock, a timer, and retention of data in the 4KB SRAM. The AON logic is powered by the AON

LDO and its clock frequency is 32kHz. The 32kHz clock can be from an internal RC clock source or

an external clock source such as a 32kHz RTC clock. The AON logic has a sleep timer inside, which

can wake up the DOOPD (Dynamic On and Off Power Domain).

DOOPD (Dynamic On and Off Power Domain): The DOOPD consists of the GFSK modulator and RF

transmitter, eFuse OTP memory, SRAM, the security engine and the peripherals.

Power operation modes:

Sleep mode: Only the AON domain is on. The DOOPD domain is shut down.

Active Mode: Both power domains are on.
