Product details
Overview
MC32PF3001A7EPR2 from NXP Semiconductors is a fixed-configuration Power Management IC (PMIC) optimized for i.MX 6UL 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 (3.0 V, 1.0 mA RTC supply)-in a 48-pin QFN 7.0 mm × 7.0 mm wettable flank package for consumer-grade operation from −40 °C to +85 °C.
For engineers reviewing the MC32PF3001A7EPR2 datasheet, MC32PF3001A7EPR2 pinout, MC32PF3001A7EPR2 application, or MC32PF3001A7EPR2 equivalent, this page provides verified regulator output voltages, OTP-programmed startup sequence (SW1=1.4 V, SW2=3.3 V, SW3=1.35 V, VCC_SD=3.3 V/1.85 V), I²C address (0x08), thermal design guidance, and validated alternative PMICs for i.MX 6UL-based industrial and consumer embedded systems.
Technical Context
The MC32PF3001A7EPR2 implements a fixed OTP-based power tree with hardwired sequencing: SW1 powers the ARM core (VDD_ARM), SW2 supplies SOC logic and DDR I/O, and SW3 delivers memory voltage; all three buck regulators operate at 2.0 MHz PWM frequency with APS/PWM/PFM mode control via I²C. Its internal 16 MHz trimmed oscillator governs switching timing and DVS slew rate (6.25 mV/μs), while the 32 kHz clock manages startup and low-power states.
Regulator configuration is immutable post-manufacture-voltage levels, sequencing order (SW1→SW2→V33→VLDO4→VCC_SD), and fault response (INTB open-drain interrupt, RESETBMCU deasserted 2 ms after final regulator enable) are pre-programmed per Table 4. The device supports optional VPWR front-end LDO for >4.5 V inputs using an external P-MOSFET, with VIN limited to ≤4.5 V when VPWR is grounded.
Key Specifications

Pinout & Package
MC32PF3001A7EPR2 uses a 48-pin QFN 7.0 mm × 7.0 mm wettable flank package (NXP part number 98ASA00933D) with exposed thermal pad (EP) tied to GND for dissipation. Pin functions are fixed per datasheet Table 2; unused switcher pins (e.g., SW1LX, SW1IN) require specific floating/bypassing per Section 7.2 footnote [1].
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INTB (Pin 1) | Open-drain interrupt output | Asserts low on fault (overvoltage, thermal, short-circuit); requires external pull-up to VDDIO |
| SD_VSEL (Pin 2) | Digital input | Selects VCC_SD output range: LOW = 2.85–3.3 V, HIGH = 1.8–1.85 V; defaults HIGH if VDDIO absent |
| RESETBMCU (Pin 3) | Open-drain reset output | Deasserts 2.0 ms after last regulator enables; signals processor ready state, not real-time regulation monitoring |
| SW1FB (Pin 6) | Analog feedback input | Closes SW1 regulation loop; must be routed away from high-current paths and terminated near output capacitor |
| SW1LX (Pins 8 & 9) | Switch node outputs | Connects directly to SW1 inductor; shared node for dual-phase layout (not paralleled outputs) |
| VCC_SD (Pin 33) | LDO output | Supplies SD card interface; bypassed with 2.2 μF ceramic capacitor; voltage set by SD_VSEL and OTP |
| VSNVS (Pin 34) | RTC supply output | Always-on 3.0 V rail for i.MX SNVS domain; bypassed with 0.47 μF capacitor; supports coin cell backup |
| EP (Pad) | Thermal ground | Exposed pad functions as primary GND return for buck regulators; must be connected to inner/external GND planes via multiple vias |
Key Features
| Feature | Design Value |
|---|---|
| OTP-configured power tree | Fixed startup sequence (SW1→SW2→V33→VLDO4→VCC_SD) and voltage setpoints eliminate runtime configuration overhead |
| Triple-buck architecture | SW1 (2.75 A), SW2 (1.25 A), SW3 (1.5 A) independently supply core, SOC, and memory rails with 2.0 MHz switching and APS/PWM/PFM mode control |
| Dual-range SD card LDO | VCC_SD supports both 1.8 V and 3.3 V SD interfaces via SD_VSEL pin-enables single-hardware design for multiple card types |
| Integrated RTC power | VSNVS delivers stable 3.0 V @ 1.0 mA with coin cell charging circuitry-maintains secure non-volatile storage during main power loss |
| Front-end VPWR LDO option | Supports up to 5.5 V input via external P-MOSFET (e.g., FDMA908PZ); internal LDOG gate driver eliminates need for discrete level-shifting |
| Trimmed 16 MHz oscillator | Provides accurate timing for PWM switching and DVS; factory-trimmable ±3% for EMI optimization without external crystal |

FAQ
What is the default I²C address of the MC32PF3001A7EPR2?
The MC32PF3001A7EPR2 has a fixed default I²C slave address of 0x08. This address is unchangeable because the device lacks address-select pins or software-configurable address registers. All communication-including register reads/writes for dynamic voltage scaling, fault status, and mode control-must occur at 0x08. No external pull-up or pull-down resistors affect this address.
How does the SD_VSEL pin affect VCC_SD output voltage on the MC32PF3001A7EPR2?
On the MC32PF3001A7EPR2, the SD_VSEL pin selects between two factory-programmed VCC_SD output ranges: when SD_VSEL is logic LOW, VCC_SD delivers 2.85–3.3 V; when HIGH, it delivers 1.8–1.85 V. The pin is buffered by VDDIO, and if VDDIO is absent, SD_VSEL defaults to HIGH-ensuring safe 1.85 V operation for SD card initialization before full power-up.
Can the MC32PF3001A7EPR2 support input voltages above 4.5 V?
Yes-the MC32PF3001A7EPR2 supports up to 5.5 V input via its optional VPWR front-end LDO. This requires populating an external P-channel MOSFET (e.g., FDMA908PZ) and connecting VPWR to the high-voltage rail. When VPWR is used, VIN must be derived from the LDO output and kept ≤4.5 V. For ≤4.5 V inputs, VPWR is grounded and VIN is used directly.
What is the startup sequence order for regulators on the MC32PF3001A7EPR2?
The MC32PF3001A7EPR2 implements a fixed OTP-programmed startup sequence per Table 4: SW1 (1.4 V) → SW2 (3.3 V) → V33 (3.3 V) → VLDO4 (1.8 V) → VCC_SD (3.3 V/1.85 V). Delays between stages are controlled by a trimmed 32 kHz clock with SEQ_CLK_SPEED = 2000 µs, resulting in typical total startup time of ~12 ms from PWRON assertion to RESETBMCU deassertion.
Does the MC32PF3001A7EPR2 include battery backup capability?
Yes-the MC32PF3001A7EPR2 integrates a dedicated VSNVS regulator (3.0 V, 1.0 mA) with built-in coin cell charging circuitry. The LICELL pin accepts a 1.2–3.6 V coin cell; when main power is present, the IC trickle-charges the cell. During main power loss, VSNVS maintains power to the i.MX processor's Secure Non-Volatile Storage (SNVS) domain, preserving RTC time and tamper logs.
