Product details
Overview
MC32PF3001A1EP from NXP Semiconductors is a pre-programmed Power Management IC (PMIC) optimized for i.MX 7 processors with DDR3L memory, delivering three buck regulators (SW1: 2.75 A, SW2: 1.25 A, SW3: 1.5 A) and seven LDOs-including VCC_SD (100 mA), V33 (350 mA), and VSNVS (1.0 mA)-to power core, I/O, memory, and RTC domains in embedded multimedia systems.
For engineers reviewing the MC32PF3001A1EP datasheet, MC32PF3001A1EP pinout, MC32PF3001A1EP application, or MC32PF3001A1EP equivalent, this page provides verified regulator output voltages, OTP-configured startup sequence (SW1_SEQ=1, SW2_SEQ=2, SW3_SEQ=5), I²C address (0x08), thermal design guidance, and validated alternatives for i.MX 7-based industrial and consumer designs.
Technical Context
The MC32PF3001A1EP implements fixed OTP-based power sequencing with trimmed 32 kHz clock timing control, supporting dynamic voltage scaling (DVS) on SW1/SW2/SW3 via I²C. Its architecture integrates a front-end VPWR LDO option (using external P-MOSFET) for input voltages up to 5.5 V, while default operation uses VIN (2.8–4.5 V) directly.
All regulators reference a factory-trimmed 16 MHz RC oscillator for switching frequency (2.0 MHz fixed per SWx), with internal bandgap-derived VCOREREF, VCOREDIG (1.28 V in off mode), and VCORE supplies powering analog/digital logic-no external loading permitted on these rails.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC32PF3001A2EP | OTP-configured for i.MX 7 with LPDDR3 (SW1_VOLT=1.10 V, SW3_VOLT=1.2 V, SW3_SEQ=5) | Targets LPDDR3 memory interface instead of DDR3L; different VDD_SOC and memory termination voltages | Select A2EP only when pairing with i.MX 7 + LPDDR3; A1EP is not functionally interchangeable due to fixed OTP voltage/sequence mapping |
| MC34PF3001A6EP | Rated for -40 °C to 105 °C industrial temp range; identical A6 OTP config (i.MX 6UL + LPDDR2) but higher thermal tolerance | Designed for extended-temperature industrial control, not i.MX 7 platforms; incompatible startup sequence and voltage setpoints | A6EP supports harsher environments but requires redesign for i.MX 6UL; A1EP remains optimal for i.MX 7 + DDR3L consumer/industrial use cases |
Compared with MC32PF3001A2EP and MC34PF3001A6EP, the MC32PF3001A1EP uniquely combines i.MX 7 + DDR3L-optimized OTP settings, consumer-grade temperature range (-40 °C to 85 °C), and wettable flank packaging for automated optical inspection-making it the sole drop-in solution for that specific processor-memory combination.

FAQ
What is the default I²C address for MC32PF3001A1EP?
The default I²C address for MC32PF3001A1EP is 0x08, as defined in its pre-programmed OTP configuration (Table 4, Rev. 5.1). This address is fixed and cannot be altered without reprogramming via OTP-though field updates require special tools and are not supported in standard operation. All register access, fault reporting, and DVS control for MC32PF3001A1EP begin at this base address.
Does MC32PF3001A1EP support dynamic voltage scaling (DVS) on all buck regulators?
Yes, MC32PF3001A1EP supports DVS on SW1, SW2, and SW3 via I²C register writes to SWxVOLT[4:0] fields. The OTP-fixed startup voltages (SW1=1.10 V, SW2=1.8 V, SW3=1.35 V) serve only as initial values; runtime adjustment is fully enabled. DVS slew rate is programmable (e.g., 12.5 mV/µs for A1 config), allowing controlled transitions during processor frequency scaling without violating SoC specifications.
How does the VCC_SD regulator voltage selection work on MC32PF3001A1EP?
VCC_SD voltage on MC32PF3001A1EP is selected by the SD_VSEL pin (Pin 2): logic LOW configures 2.85–3.30 V output for standard SD cards, while logic HIGH selects 1.80–1.85 V for UHS-I or eMMC interfaces. The SD_VSEL buffer is powered by VDDIO; if VDDIO is absent, the default logic HIGH forces 1.85 V mode-ensuring safe boot even before I/O supply stabilization.
Can MC32PF3001A1EP operate with a 5.0 V input supply?
Yes, MC32PF3001A1EP supports 5.0 V input via the VPWR pin when used with an external P-channel MOSFET (e.g., FDMA908PZ) and associated resistor divider (R1/R2). In this configuration, the internal LDOG pin drives the FET gate to regulate VIN to ≤4.5 V. Direct connection of 5.0 V to VIN is prohibited-it exceeds the absolute maximum rating and risks permanent damage to MC32PF3001A1EP.
What is the purpose of the VSNVS rail on MC32PF3001A1EP?
The VSNVS rail on MC32PF3001A1EP provides a dedicated 3.0 V, 1.0 mA always-on supply for the Secure Non-Volatile Storage (SNVS) and Real-Time Clock (RTC) domains of i.MX processors. It remains active during main power loss and includes integrated coin cell charging-enabling continuous timekeeping and secure key storage without external circuitry. Bypassing with 0.47 µF to GND is mandatory for stability.
