Product details
Overview
MC34PF3001A1EP from NXP Semiconductors is a fixed-configuration power management IC (PMIC) designed exclusively for i.MX 7 processors with DDR3L memory. It integrates three buck regulators (SW1: 2.75 A, SW2: 1.25 A, SW3: 1.5 A), seven LDOs including VCC_SD and V33, and an RTC supply (VSNVS: 3.0 V, 1.0 mA), delivering full power sequencing for multimedia application processors in industrial edge devices.
For engineers reviewing the MC34PF3001A1EP datasheet, MC34PF3001A1EP pinout, MC34PF3001A1EP application, or MC34PF3001A1EP equivalent, this page provides verified regulator output voltages, OTP-programmed startup sequence (SW1_SEQ=1, SW2_SEQ=2, SW3_SEQ=5), thermal-safe QFN-48 wettable flank package details, and confirmed I²C address (0x08) - all validated against NXP's Rev. 5.1 product data sheet.
Technical Context
The MC34PF3001A1EP implements a fixed OTP-based power tree with pre-programmed sequencing optimized for i.MX 7 + DDR3L systems: SW1 powers the ARM Cortex-A7 core at 1.10 V (2.75 A), SW2 supplies I/O domains at 1.8 V (1.25 A), and SW3 delivers 1.35 V (1.5 A) to DDR3L termination. Startup timing is governed by a trimmed 32 kHz clock with SEQ_CLK_SPEED = 2000 µs and RESETBMCU deassertion delayed 2.0 ms after final regulator enable.
It supports dual-input operation: VIN (2.8–4.5 V) for battery-powered systems or VPWR + external PMOS for 3.7–5.5 V industrial rails. The I²C interface (SCL/SDA, 0x08 default) enables runtime voltage adjustment and fault monitoring, while logic pins (PWRON, INTB, RESETBMCU, SD_VSEL) provide direct hardware control without software overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.8 V to 4.5 V on VIN; 3.7 V to 5.5 V on VPWR with external PMOS - enables flexible power source selection across battery and industrial rail designs |
| SW1 Output | 1.10 V @ 2.75 A - factory-trimmed core voltage for i.MX 7 A7 processor, sequenced first (SEQ=1) |
| SW2 Output | 1.80 V @ 1.25 A - fixed I/O voltage for i.MX 7 peripherals and DDR3L interface, sequenced second (SEQ=2) |
| VCC_SD Output | 3.3 V / 1.85 V selectable via SD_VSEL pin - supports dual-voltage SD card interface without external switching |
| VSNVS Output | 3.0 V @ 1.0 mA - always-on RTC supply with integrated coin cell charger for secure non-volatile state retention |
| I²C Address | 0x08 (default) - fixed slave address enabling plug-and-play integration with i.MX 7 host controllers |
| Package | 48-pin QFN 7.0 mm × 7.0 mm WF-type - wettable flank design ensures reliable solder joint inspection for industrial reflow processes |
Pinout & Package
MC34PF3001A1EP uses a 48-pin QFN (98ASA00933D) with exposed thermal pad (EP), rated for -40 °C to 105 °C industrial operation. Pin functions are fully defined per NXP's Rev. 5.1 datasheet, with dedicated GNDREF1/GNDREF2/GNDREF grounding for analog regulator stability and noise isolation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INTB | Open-drain interrupt output | Asserts low on fault (overvoltage, thermal, short-circuit); requires external pull-up for host MCU notification |
| SD_VSEL | Digital input | Selects VCC_SD output: HIGH = 1.80–1.85 V (SD card logic), LOW = 2.85–3.3 V (legacy SD interface) |
| RESETBMCU | Open-drain reset output | Deasserts 2.0 ms after last regulator enables - synchronizes i.MX 7 exit from POR with full power rail stabilization |
| SW1LX, SW2LX, SW3LX | Buck switch node outputs | Connect directly to respective inductors; require tight layout to minimize EMI and switching losses |
| VIN, VPWR | Main and front-end inputs | VIN used for ≤4.5 V supplies; VPWR + external PMOS enables 5.5 V operation with internal overvoltage protection |
| EP (exposed pad) | Thermal ground | Mandatory connection to inner/outer PCB ground planes via multiple vias - critical for thermal dissipation at full load |
Key Features
| Feature | Design Value |
|---|---|
| OTP-configured startup sequence | Fixed SW1→SW2→SW3→VLDO4→V33→VCC_SD ordering eliminates firmware dependency and guarantees deterministic boot for i.MX 7 DDR3L systems |
| Integrated coin cell charger | Enables seamless RTC backup using standard CR2032 cells - no external charging circuitry required for industrial logging applications |
| Dual-input voltage support | Hardware-selectable VIN (≤4.5 V) or VPWR+PMOS (≤5.5 V) paths allow single PMIC design across battery-powered and mains-powered variants |
| VCC_SD dual-voltage regulation | Single LDO supports both 1.8 V SDIO and 3.3 V legacy SD modes via SD_VSEL pin - reduces BOM count vs. discrete LDO solutions |
| Trimmed 32 kHz startup clock | Factory-calibrated timing reference ensures ±10 % accuracy on regulator enable delays - critical for meeting i.MX 7 power-on reset timing windows |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC33PF3001A6EP | Same PF3001 silicon, automotive-grade (-40 °C to 105 °C), OTP programmed for i.MX 6UL + LPDDR2 | Targets automotive infotainment with different DDR interface and lower core voltage (1.4 V SW1) | Select only if migrating from i.MX 6UL platform; not drop-in compatible due to distinct startup sequence and voltage setpoints |
| MC34PF3001A7EP | Same PF3001 silicon, industrial-grade (-40 °C to 105 °C), OTP programmed for i.MX 6UL + DDR3L | Optimized for i.MX 6UL SoC with 1.35 V SW3 and 3.3 V V33 - lacks i.MX 7-specific SW1/SW2 trim points | Valid alternative only when redesigning for i.MX 6UL; incompatible with i.MX 7 DDR3L timing due to different SW3_SEQ and PU_CONFIG settings |
Compared with MC34PF3001A1EP, MC33PF3001A6EP and MC34PF3001A7EP share identical regulator architecture and pinout but differ in OTP-programmed voltages, sequencing order, and target SoC - making them functionally distinct rather than interchangeable parts for i.MX 7 DDR3L systems.

FAQ
What is the default I²C address for MC34PF3001A1EP?
The default I²C slave address for MC34PF3001A1EP is 0x08, as specified in Table 4 of the NXP PF3001 Rev. 5.1 datasheet. This address is fixed and cannot be altered via hardware pins; all register reads and writes to MC34PF3001A1EP must use this base address. The device supports standard-mode (100 kHz) and fast-mode (400 kHz) I²C communication for runtime voltage and fault status monitoring.
Does MC34PF3001A1EP support DDR3L memory interfaces?
Yes, MC34PF3001A1EP is specifically configured for i.MX 7 with DDR3L memory, as indicated by its A1 programming option. Its SW3 regulator delivers 1.35 V at 1.5 A with SEQ=5, matching DDR3L VDDQ requirements, and its VCC_SD LDO supports 1.8 V SDIO signaling. The OTP configuration ensures correct timing alignment between DDR3L initialization and core power-up sequences.
What is the purpose of the SD_VSEL pin on MC34PF3001A1EP?
The SD_VSEL pin on MC34PF3001A1EP selects the output voltage range of the VCC_SD LDO: logic HIGH configures 1.80–1.85 V for SDIO interfaces, while logic LOW selects 2.85–3.3 V for legacy SD card operation. This pin is powered by VDDIO and defaults to HIGH if VDDIO is absent, ensuring safe low-voltage operation during power-up. MC34PF3001A1EP uses this signal to avoid external level-shifting components.
Can MC34PF3001A1EP operate from a 5 V input supply?
Yes, MC34PF3001A1EP supports 5 V input via the VPWR pin when used with an external PMOS pass FET (e.g., Fairchild FDMA908PZ), as described in Section 8.3.5.1. In this configuration, the internal front-end LDO regulates VIN to ≤4.5 V, protecting downstream regulators. Direct 5 V connection to VIN is not allowed - doing so exceeds the 4.5 V absolute maximum rating and may damage MC34PF3001A1EP.
What is the thermal rating and package type of MC34PF3001A1EP?
MC34PF3001A1EP uses a 48-pin QFN package (98ASA00933D, 7.0 mm × 7.0 mm) with wettable flank (WF-type) leads and an exposed thermal pad (EP). It is rated for industrial operation from -40 °C to +105 °C ambient temperature. The EP pad must be soldered to a multi-layer PCB ground plane with ≥6 thermal vias to maintain junction temperature below 125 °C at full 2.75 A SW1 load.
