PF8121 12-channel power management integrated circuit for high performance applications Rev. 5 24 February 2021 Product data sheet 1 Overview The PF8121 is a power management integrated circuit (PMIC) designed for high performance consumer applications. It features seven high efficiency buck converters and four 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 seven high efficiency buck converters Four linear regulators with load switch options RTC supply and coin cell charger Watchdog timer/monitor Voltage and system monitoring circuits One time programmable device configuration 2 3.4 MHz I C communication interface 56-pin 8 x 8 QFN packageNXP Semiconductors PF8121 12-channel power management integrated circuit for high performance applications 3 Simplified application diagram PF8121 Coin Cell MCU VSNVS RTC Clock BUCK1 VDD MAIN BUCK2 VIN: 2.7 V to 5.5 V BUCK3 VDD GPU VDD CPU BUCK4 BUCK5 VDD DDRIO 1.8 V I/O BUCK6 (LV GPIO) 3.3 V I/O BUCK7 (HV GPIO) LDO1 VDD SCU LDO2 SD Card LDO3 2.5 V I/O LDO4 MISC CONTROL INTERFACING AND SIGNALS 2 I C COMMUNICATIONS 2 I C SIMCARD eMMC Supply SD Card Ethernet DRAM LPDDR MISCELLANEOUS Memory PERIPHERALS aaa-032432 Figure 1.Simplified application diagram 4 Ordering information Table 1.Device options Type Package Name Description Version PF8121 HVQFN56 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 System comments Safety grade OTP ID processor MC32PF8121A0EP Consumer i.MX8M Mini Not programmed n/a n/a MC32PF8121EUEP Consumer i.MX8M Mini LPDDR4 (Vin > 4.0 V, SW7 = 3.3 V, SW4 = n/a
