Product details
Overview
MC32PF3001A5EP from NXP Semiconductors is a fixed-configuration Power Management IC (PMIC) optimized for i.MX 6 SoloLite processors with LPDDR2 memory, delivering three buck regulators (SW1: 2.75 A, SW2: 1.25 A, SW3: 1.5 A), seven LDOs including VCC_SD (100 mA, dual-voltage), and RTC backup supply (VSNVS: 3.0 V, 1.0 mA). It supports I²C configuration and dynamic voltage scaling for embedded multimedia systems.
For engineers reviewing the MC32PF3001A5EP datasheet, MC32PF3001A5EP pinout, MC32PF3001A5EP application, or MC32PF3001A5EP equivalent, key selection criteria include its OTP-programmed startup sequence (SW1_SEQ=1, SW2_SEQ=2, SW3_SEQ=4, VCC_SD_SEQ=2), fixed 2.0 MHz switching frequency, -40 °C to 85 °C industrial temperature grade, and QFN 48-pin 7.0 mm × 7.0 mm wettable flank package.
Technical Context
The MC32PF3001A5EP implements a deterministic, OTP-driven power-up sequence with 2000 µs clock speed and fixed regulator phasing-no runtime reconfiguration of timing or sequencing. Its three buck regulators use synchronous rectification with integrated drivers, supporting PWM, PFM, and APS modes; SW1 targets core voltage (1.375 V), SW2 supplies DDR I/O (3.15 V), and SW3 powers logic domains (1.2 V).
Control is split between dedicated logic pins (PWRON, RESETBMCU, INTB, SD_VSEL) and I²C register access. The VCC_SD regulator's output voltage (1.80 V or 3.15 V) is selected dynamically via SD_VSEL, while VSNVS operates as a dedicated 3.0 V RTC rail with coin-cell charging capability and independent biasing from VIN or backup source.

FAQ
What is the primary target processor for MC32PF3001A5EP?
The MC32PF3001A5EP is specifically programmed for the i.MX 6 SoloLite processor with LPDDR2 memory, as indicated by its OTP configuration A5. It delivers optimized voltages-including 1.375 V for the ARM core, 3.15 V for DDR I/O, and dual-range 1.80 V/3.15 V for SD card interface-to match this exact processor-memory combination.
Does MC32PF3001A5EP support runtime voltage adjustment via I²C?
Yes, MC32PF3001A5EP supports I²C-based voltage adjustment for all buck regulators (SW1/SW2/SW3) and LDOs during active operation. While its startup sequence and default voltages are fixed by OTP A5, the I²C interface (default address 0x08) allows dynamic DVS, fault monitoring, and register-level control without requiring hardware changes.
What is the function of the SD_VSEL pin on MC32PF3001A5EP?
The SD_VSEL pin on MC32PF3001A5EP selects the output voltage of the VCC_SD regulator: logic low configures 3.15 V for standard SDIO operation, while logic high selects 1.80 V for low-voltage SD card compatibility. This hardware-controlled selection enables seamless dual-voltage SD interface support without firmware intervention.
How does MC32PF3001A5EP handle RTC power during main supply loss?
MC32PF3001A5EP maintains RTC functionality during main supply loss using its integrated VSNVS regulator and LICELL circuitry. When VIN drops, it automatically switches VSNVS output to the connected coin cell, sustaining 3.0 V at 1.0 mA to the i.MX SNVS domain while simultaneously charging the cell when main power is restored.
Is MC32PF3001A5EP pin-compatible with other PF3001 variants like MC33PF3001A6EP?
Yes, MC32PF3001A5EP is fully pin-compatible with MC33PF3001A6EP and all other PF3001 family members, sharing the identical 48-pin QFN 7.0 mm × 7.0 mm wettable flank package, pin assignment, and electrical interface. Differences are limited to temperature grade, qualification, and OTP programming-not physical or signal-layer compatibility.
