PF8101 PF8201 9-channel power management integrated circuit for high performance applications Rev. 4 24 February 2021 Product data sheet 1 Overview The PF8101/PF8201 is a power management integrated circuit (PMIC) designed for high performance i.MX 8 based applications. It features five high efficiency buck converters and three linear regulators for powering the processor, memory and miscellaneous peripherals. Built-in one time programmable memory stores key startup configurations, drastically reducing external components typically used to set output voltage and sequence of 2 external regulators. Regulator parameters are adjustable through high-speed I C after start up offering flexibility for different system states. 2 Features Up to five high efficiency buck converters Three linear regulators with load switch options RTC supply and coin cell charger Watchdog timer/monitor Monitoring circuit to fit ASIL B safety level One time programmable device configuration 2 3.4 MHz I C communication interface 56-pin 8 x 8 QFN packageNXP Semiconductors PF8101 PF8201 9-channel power management integrated circuit for high performance applications 3 Simplified application diagram PF8101 / PF8201 MCU VSNVS VDD SNVS BUCK1 VDD MAIN VDD GPU BUCK2 VIN: VDD CPU(A35) 2.7 V to 5.5 V VDD DDRIO BUCK5 1.8 V I/O BUCK6 (LV GPIO) 3.3 V I/O BUCK7 (HV GPIO) LDO1 VDD SCU LDO2 SDCARD0 LDO3 2.5 V l/O CONTROL INTERFACING AND SIGNALS 2 I C COMMUNICATIONS 2 I C SIMCARD eMMC Supply SD Card Ethernet DRAM LPDDR MISCELLANEOUS Memory PERIPHERALS aaa-029315 Figure 1.Simplified application diagram 4 Ordering information Table 1.Device options Type Package Name Description Version PF8101 (automotive) HVQFN56, plastic, thermally enhanced very thin quad flat non-leaded package, SOT684-21 wettable flanks 56 terminals 0.5 mm pitch 8 mm x 8 mm x 0.85 mm body (DD/SC) PF8201 (automotive) HVQFN56 PF8101 (industrial) HVQFN56, plastic, thermally enhanced very thin quad flat non-leaded package, SOT684-21 56 terminals 0.5 mm pitch 8 mm x 8 mm x 0.85 mm body Table 2.Ordering information 1 Part number Target market NXP processor System comments Safety grade OTP ID MC33PF8101A0ES Automotive n/a Not programmed QM n/a MC34PF8101A0EP Industrial n/a Not programmed QM n/a MC33PF8201A0ES Automotive n/a Not programmed ASIL B n/a 1 To order parts in tape and reel, add the R2 suffix to the part number.
