Product details
Overview
MC32PF3001A3EPR2 from NXP Semiconductors is a pre-programmed Power Management IC (PMIC) optimized for i.MX 6 SoloX 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, dual-voltage SD card support), V33 (350 mA), and VSNVS (1.0 mA RTC supply)-in a 48-pin QFN 7.0 mm × 7.0 mm wettable flank package. It enables full power sequencing for multimedia edge devices.
For engineers reviewing the MC32PF3001A3EPR2 datasheet, MC32PF3001A3EPR2 pinout, MC32PF3001A3EPR2 application, or MC32PF3001A3EPR2 equivalent, this page provides verified regulator output voltages, OTP-configured startup sequence (SW1_SEQ=2, SW2_SEQ=4, SW3_SEQ=3), I²C address (0x08), thermal management guidance, and validated alternatives for i.MX 6SX-based industrial control and home automation systems.
Technical Context
The MC32PF3001A3EPR2 implements fixed OTP-based power sequencing tailored to i.MX 6 SoloX with DDR3L: SW1 powers the ARM core at 1.375 V (SEQ=2), SW2 supplies DDR3L I/O at 3.3 V (SEQ=4), and SW3 delivers 1.35 V to logic domains (SEQ=3). All buck regulators operate at 2.0 MHz PWM frequency with APS/PWM/PFM mode selection via I²C.
It integrates a coin-cell–backed VSNVS rail (3.0 V, 1.0 mA), programmable VCC_SD voltage selection via SD_VSEL pin, and optional VPWR front-end LDO support using an external P-MOSFET for input voltages up to 5.5 V. Internal core supplies VCOREDIG (1.28 V in off mode) and VCOREREF are decoupled per spec.

Pinout & Package
MC32PF3001A3EPR2 uses a 48-pin QFN 7.0 mm × 7.0 mm wettable flank package (98ASA00933D) with exposed thermal pad (EP). Pin functions are defined per NXP PF3001 Rev. 5.1 datasheet Section 7.2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INTB (Pin 1) | Open-drain interrupt output | Asserts low on fault (e.g., overvoltage, thermal shutdown); requires external pull-up |
| SD_VSEL (Pin 2) | Digital input | Selects VCC_SD output: LOW = 2.85–3.3 V, HIGH = 1.8–1.85 V for SD card compatibility |
| RESETBMCU (Pin 3) | Open-drain reset output | Deasserts 2.0 ms after final regulator enables - used to release i.MX 6SX from POR |
| SW1FB (Pin 6) | Analog feedback input | Closes SW1 regulation loop; must route separately from high-current paths for stability |
| SW1LX (Pins 8 & 9) | Switch node outputs | Drive external inductor; both pins tied internally - parallel connection improves current handling |
| VSNVS (Pin 34) | RTC/always-on supply output | 3.0 V @ 1.0 mA; powered from VIN or coin cell (LICELL) - maintains SNVS domain during sleep |
| LICELL (Pin 36) | Coin-cell interface | Bidirectional charge path; supports backup for RTC and SRAM retention when main power fails |
| SCL/SDA (Pins 45–46) | I²C interface | Standard-mode (100 kHz) or fast-mode (400 kHz); VDDIO-referenced (1.7–3.6 V) |
Key Features
| Feature | Design Value |
|---|---|
| OTP-configured power tree | Fixed startup sequence (SW1_SEQ=2, SW2_SEQ=4, SW3_SEQ=3) eliminates external configuration components for i.MX 6SX + DDR3L |
| Dynamic voltage scaling (DVS) | SW1 supports programmable ramp rate (6.25 mV/µs) for controlled core voltage transitions during DVFS |
| Dual-voltage SD card regulator | VCC_SD output switches between 1.8 V and 3.3 V ranges via SD_VSEL - meets SD 3.0 specification requirements |
| Integrated RTC power path | VSNVS rail with coin-cell charging (LICELL) and seamless switchover - sustains secure real-time clock and tamper detection |
| Front-end VPWR LDO option | Supports 4.5–5.5 V inputs via external P-MOSFET (e.g., FDMA908PZ); includes VPWROV detection and interrupt |
| Thermal-aware design | Exposed pad (EP) tied to internal/external ground planes via vias - enables ≤45 °C/W junction-to-ambient under 2 W dissipation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC34PF3001A3ES | Rated for −40 °C to 105 °C industrial temp range; identical OTP A3 configuration and pinout | Required for extended-temperature industrial gateways operating above 85 °C ambient | Select MC34PF3001A3ES when board-level thermal design exceeds 85 °C junction temperature under full load |
| MC33PF3001A3EP | Automotive-grade (−40 °C to 105 °C), AEC-Q100 qualified; same OTP A3 programming but different qualification testing | Targeted at automotive infotainment head units using i.MX 6SX, not consumer/industrial designs | Choose MC33PF3001A3EP only if AEC-Q100 compliance and automotive PPAP documentation are mandatory |
Compared with MC32PF3001A3EPR2, MC34PF3001A3ES offers higher thermal margin without layout changes, while MC33PF3001A3EP adds automotive qualification overhead irrelevant to industrial/home use - making MC32PF3001A3EPR2 the optimal cost-performance choice for i.MX 6SX consumer and commercial applications.

FAQ
What is the default I²C address of the MC32PF3001A3EPR2?
The MC32PF3001A3EPR2 has a fixed default I²C address of 0x08, as defined in its OTP configuration A3. This address cannot be altered in hardware and is used for all register read/write operations during runtime configuration or fault monitoring. The I²C interface operates with standard- or fast-mode timing and requires pull-up resistors on SCL and SDA referenced to VDDIO.
How does the MC32PF3001A3EPR2 support DDR3L memory on i.MX 6 SoloX?
The MC32PF3001A3EPR2 supports DDR3L memory through its SW2 buck regulator, pre-programmed to deliver 3.3 V at 1.25 A with startup sequence position 4 (SW2_SEQ=4). This matches DDR3L VDDQ requirements and aligns with i.MX 6 SoloX memory controller timing. The OTP A3 configuration also sets SW2_VOLT=3.3 V and SW2_FREQ=2.0 MHz for optimal noise performance near memory traces.
Can the MC32PF3001A3EPR2 operate with a 5.0 V input supply?
Yes - the MC32PF3001A3EPR2 supports 5.0 V input via the VPWR pin when used with an external P-channel MOSFET (e.g., FDMA908PZ) and associated resistor divider. In this configuration, the internal LDOG driver controls the FET to regulate VIN to ≤4.5 V. Direct 5.0 V connection to VIN is not allowed and will damage the device.
What is the purpose of the SD_VSEL pin on the MC32PF3001A3EPR2?
The SD_VSEL pin on the MC32PF3001A3EPR2 selects the output voltage range of the VCC_SD LDO: logic LOW configures 2.85–3.3 V for legacy SD cards, while logic HIGH configures 1.8–1.85 V for UHS-I SD cards. This pin is sampled during startup and latched; it must be driven by the i.MX 6 SoloX GPIO before PWRON assertion to ensure correct initialization.
Does the MC32PF3001A3EPR2 include battery backup capability?
Yes - the MC32PF3001A3EPR2 integrates a dedicated LICELL pin and VSNVS regulator that supports coin-cell backup. When main power fails, VSNVS automatically switches to the coin cell to maintain the i.MX 6 SoloX SNVS domain, preserving RTC time, tamper logs, and secure key storage. Charging current is limited and temperature-compensated per NXP specification.
