CMI 112: ACT88329VU112-T
CMI 112 is optimized for the Atmel SAMA5D2 processor. The output voltages and sequencing are directly compatible
with the Atmel SAMA5D2 processor. CMI 112 is configured for a 5V input voltage. Refer to Qorvo’s Application Note,
“ATMEL SAMA5D2 Power Solution Using the AT88321 (AN130)” for additional details about how to use this PMIC to
power the SAMA5D2
