Product details
Overview
MC32PF3000A7EP from NXP Semiconductors is a power management IC (PMIC) engineered for i.MX 6UL application processors with DDR3L memory, delivering four buck regulators (SW1A: 1.0 A, SW1B: 1.75 A, SW2: 1.25 A, SW3: 1.5 A), six LDOs, VREFDDR reference, and coin-cell charging - enabling full-system power for industrial embedded designs.
For engineers reviewing the MC32PF3000A7EP datasheet, MC32PF3000A7EP pinout, MC32PF3000A7EP application, or MC32PF3000A7EP equivalent, key selection factors include OTP-programmable startup sequence, dynamic voltage scaling support for ARM cores, I²C-configurable regulator voltages, and wettable-flank 48-QFN packaging for automated optical inspection.
Technical Context
The MC32PF3000A7EP implements SMARTMOS technology with integrated OTP memory to store startup timing, voltage settings, and regulator enable sequences - eliminating external configuration components. Its buck regulators support independent or combined operation (SW1A/SW1B as single 2.75 A channel), programmable PWM/PSM modes, and soft-start ramp control via SWDVS_CLK bit.
It features dual-input capability (VIN ≤ 4.5 V or VPWR up to 5.5 V with external PFET), dedicated DDR3L-compatible VREFDDR (0.5 × SW3_OUT), and VSNVS rail (3.0 V, 1.0 mA) for secure real-time clock backup - all coordinated through I²C interface and direct logic signals (PWRON, STANDBY, RESETBMCU, INTB).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.8–4.5 V (VIN) or 3.7–5.5 V (VPWR with external PFET) |
| SW1A Output | 0.7–1.425 V / 1.8 V / 3.3 V, 1.0 A - configurable for i.MX 6UL core supply |

| VCC_SD Output | 1.80–1.85 V or 2.85–3.30 V, 100 mA - SD card dual-voltage compliance |
| I²C Address | Programmable 0x08–0x0F - avoids bus conflicts in multi-PMIC systems |
| Startup Sequence | OTP-programmable slot timing (0.5 ms or 2.0 ms steps) across 15 positions |
Pinout & Package
MC32PF3000A7EP uses a 48-pin QFN package (98ASA00933D), 7.0 mm × 7.0 mm, wettable flank (WF-type), with exposed thermal pad (EP) tied to ground for enhanced thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INTB | Open-drain fault interrupt output | Asserts low on overcurrent, undervoltage, or thermal fault - requires external pull-up |
| RESETBMCU | Open-drain processor reset output | Deasserts 2.0 ms after last regulator enables - configurable for fault-sensing mode |
| PWRON | Power-on control input | Level- or edge-triggered (OTP-configurable) to initiate startup or sleep entry |
| STANDBY | Standby mode control input | Active-high or active-low (OTP-selectable) to enter/exit low-power standby state |
| SD_VSEL | VCC_SD voltage select input | Determines VCC_SD output range: 1.8 V (high) or 3.15 V (low) - powered by VDDIO |
| SCL/SDA | I²C interface pins | Standard open-drain bus interface (VDDIO-referenced, 4.7 kΩ pull-ups required) |
| SW1ALX/SW1BLX | Switch node outputs | Connect to respective inductors; configurable for independent or paralleled operation |
| VSNVS | Secure non-volatile supply | 3.0 V, 1.0 mA output - powers i.MX SNVS domain; supports coin-cell backup |
Key Features
| Feature | Design Value |
|---|---|
| OTP-programmable startup sequence | Eliminates external RC timing networks; enables precise, repeatable power-up ordering across 15 time slots |
| Dynamic voltage scaling (DVS) | Adjusts SW1A/SW1B output in real time to match i.MX 6UL core performance states - reduces dynamic power |
| VREFDDR tracking architecture | Generates DDR3L reference directly proportional to SW3 output - ensures stable memory interface under load transients |
| Wettable flank QFN package | Enables automated optical inspection (AOI) of solder joints - improves manufacturing yield for industrial PCBs |
| VPWR front-end LDO support | Allows safe operation with 5.5 V input using external P-MOSFET - extends system input range without internal stress |

FAQ
What is the operating temperature range for MC32PF3000A7EP?
MC32PF3000A7EP is rated for -40 °C to +85 °C ambient operation, making it suitable for consumer and industrial applications where extended thermal performance is not required. This distinguishes it from the automotive-grade MC33PF3000A7ES (-40 °C to +105 °C) and industrial-grade MC34PF3000A7ES (-40 °C to +105 °C), both sharing identical OTP option 7 for i.MX 6UL with DDR3L.
How does MC32PF3000A7EP support DDR3L memory interfaces?
MC32PF3000A7EP supports DDR3L via its VREFDDR output, which generates a precise 0.5 × SW3_OUT voltage (range: 0.45–0.825 V) with 10 mA drive capability. This tracking architecture ensures the DDR reference remains proportionally stable relative to the SW3-supplied DDR core voltage - critical for signal integrity and JEDEC-compliant DDR3L timing margins.
Can MC32PF3000A7EP be used with input voltages above 4.5 V?
Yes - MC32PF3000A7EP supports up to 5.5 V input via the VPWR pin when paired with an external P-MOSFET configured as a front-end LDO. The internal regulators remain referenced to ≤4.5 V, protecting circuitry while enabling compatibility with common 5 V system rails. VIN pin usage is limited to ≤4.5 V.
What is the purpose of the SD_VSEL pin on MC32PF3000A7EP?
The SD_VSEL pin on MC32PF3000A7EP selects between two VCC_SD output ranges: logic high configures 1.80–1.85 V for UHS-I SD cards, while logic low configures 2.85–3.30 V for legacy SD/SDIO peripherals. Its buffer is powered by VDDIO, defaulting to high if VDDIO is absent - ensuring safe default behavior during power sequencing.
Is MC32PF3000A7EP pin-compatible with other PF3000 variants?
Yes - all PF3000 variants including MC32PF3000A7EP, MC33PF3000A7ES, and MC34PF3000A7ES share identical 48-QFN pinout, electrical characteristics, and register map. Differences are limited to temperature grade, qualification testing, and package suffix (EP vs ES); no PCB redesign is needed when migrating between them for the same OTP option (7).
