Product details
Overview
MC32PF3000A7EPR2 from NXP Semiconductors is a power management IC (PMIC) engineered for i.MX 6UL application processors with DDR3L memory support, delivering four buck regulators (SW1A: 1.0 A, SW1B: 1.75 A, SW2: 1.25 A, SW3: 1.5 A), six LDOs including V33 (350 mA) and VCC_SD (100 mA), RTC supply (VSNVS, 3.0 V/1.0 mA), DDR reference (VREFDDR, 0.5–0.9 V), and coin-cell charging - all in a single 48-pin QFN package for embedded industrial systems.
For engineers reviewing the MC32PF3000A7EPR2 datasheet, MC32PF3000A7EPR2 pinout, MC32PF3000A7EPR2 application, or MC32PF3000A7EPR2 equivalent, this page delivers verified regulator output ranges, I²C-configurable startup sequencing, dynamic voltage scaling modes (PWM/PFM/APS), OTP-programmable power tree, and thermal-aware wettable-flank QFN package details essential for i.MX 6UL-based industrial control and home automation designs.
Technical Context
The MC32PF3000A7EPR2 implements a SMARTMOS-based multi-rail architecture with configurable SW1A/SW1B operation (independent or combined 2.75 A), programmable soft-start timing (0.5 ms or 2.0 ms per slot), and DVS ramp rates (25 mV/2 µs or 25 mV/4 µs). Its OTP memory stores startup sequence, voltage setpoints, PWRON edge/level configuration, and I²C address (0x08–0x0F).
It supports dual-input operation: VIN (2.8–4.5 V) or VPWR with external PFET (3.7–5.5 V), includes dedicated VREFDDR generation referenced to SW3 output, and integrates STANDBY/RESETBMCU/INTB logic-level interfaces for seamless coordination with i.MX 6UL's power states and fault handling.

FAQ
What is the primary target processor for MC32PF3000A7EPR2?
MC32PF3000A7EPR2 is specifically programmed for the NXP i.MX 6UL application processor with DDR3L memory interface. Its OTP configuration (code A7) defines regulator voltages, startup sequence, and timing optimized for i.MX 6UL's VDD_ARM, VDD_SOC, and NVCC_DRAM_CKE power domains - not compatible with i.MX 7 or i.MX 6SX without reprogramming.
Does MC32PF3000A7EPR2 support dynamic voltage scaling (DVS) for the i.MX 6UL core?
Yes, MC32PF3000A7EPR2 supports real-time DVS for the i.MX 6UL core via its SW1A and SW3 buck regulators. SW1A offers 0.70–1.425 V output with 25 mV steps, and SW3 provides 0.90–1.65 V - both configurable through I²C registers to match CPU frequency scaling demands while maintaining stability under transient loads.
How is the VREFDDR voltage generated and what is its accuracy?
MC32PF3000A7EPR2 generates VREFDDR as 0.5 × SW3 output voltage, ensuring automatic tracking to DDR3L VDDQ requirements. It delivers 0.5–0.9 V at 10 mA with hardware-based ratio accuracy - eliminating external resistor dividers and calibration, and meeting JEDEC DDR3L reference tolerance without software intervention.
Can MC32PF3000A7EPR2 operate with a 5 V input supply?
Yes, MC32PF3000A7EPR2 supports 5 V input via the VPWR pin using an external PFET and the LDOG gate-drive output. When VPWR > 4.5 V, the external PFET acts as a front-end LDO to clamp internal regulator inputs to ≤4.5 V - preserving reliability while enabling direct connection to standard 5 V system rails.
What is the function of the SD_VSEL pin on MC32PF3000A7EPR2?
The SD_VSEL pin on MC32PF3000A7EPR2 selects the output voltage range of the VCC_SD LDO: logic HIGH configures 1.80–1.85 V for high-speed SD card operation, while logic LOW selects 2.85–3.30 V for legacy SD/SDIO peripherals. Its input buffer is powered by VDDIO, defaulting to HIGH if VDDIO is absent.
