Product details
Overview
MC32PF3000A2EP from NXP Semiconductors is a power management IC (PMIC) engineered for i.MX 7 processors with LPDDR3 memory, integrating four buck regulators (SW1A/B up to 2.75 A combined), six LDOs, RTC supply (VSNVS, 3.0 V), DDR reference (VREFDDR, 0.5–0.9 V), and coin-cell charging. It delivers complete system power for application processors, memory, and peripherals in space-constrained portable electronics.
For engineers reviewing the MC32PF3000A2EP datasheet, MC32PF3000A2EP pinout, MC32PF3000A2EP application, or MC32PF3000A2EP equivalent, key selection considerations include OTP-programmable startup sequence, dynamic voltage scaling support for ARM cores, I²C-configurable regulator voltages, and compatibility with i.MX 7 + LPDDR3 power tree requirements.
Technical Context
The MC32PF3000A2EP implements a multi-rail architecture with configurable SW1A/SW1B buck pairing (1.0 A + 1.75 A → 2.75 A single-phase), programmable soft-start timing (0.5 ms or 2.0 ms per slot), and OTP-based initialization that eliminates external configuration components. Its control logic supports three power states-On, Standby, and Sleep/LPSR-with PWRON edge- or level-triggered wake-up and STANDBY polarity inversion via OTP.
It features SMARTMOS process technology enabling low quiescent current operation, integrated VREFDDR generation referenced to SW3 output (VREFDDR = 0.5 × SW3_OUT), and dual-input capability (VIN ≤ 4.5 V or VPWR 3.7–5.5 V with external PFET). The I²C interface (address 0x08–0x0F) enables real-time voltage adjustment and fault monitoring via INTB and RESETBMCU signals.
Key Specifications

Pinout & Package
MC32PF3000A2EP uses a 48-pin QFN package (7.0 mm × 7.0 mm, wettable flank, 98ASA00933D), rated for −40 °C to +85 °C and intended for consumer applications. Exposed pad (EP) serves as thermal and ground return for buck/boost regulators.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INTB | Open-drain interrupt output | Active-low fault indicator; asserts on overcurrent, UVLO, or thermal events |
| SW1ALX / SW1BLX | Switch node outputs | Connect to shared inductor when SW1A/B operate in combined 2.75 A mode |
| VREFDDR / VINREFDDR / VHALF | DDR reference generation network | VHALF provides half-supply bias; VINREFDDR supplies internal reference; VREFDDR drives DDR termination |
| SD_VSEL | Digital input for VCC_SD selection | Selects 1.8 V/1.85 V (SD_VSEL = HIGH) or 2.85–3.3 V (SD_VSEL = LOW) for SD card I/O rails |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC33PF3000A2ES | Automotive-grade (-40 °C to +105 °C), identical OTP config (i.MX 7 + LPDDR3), same pinout | Qualified for automotive infotainment and ADAS displays; requires AEC-Q100 compliance | Select when operating ambient exceeds +85 °C or automotive qualification is mandatory |
| MC34PF3000A2EP | Industrial-grade (-40 °C to +105 °C), identical OTP config (i.MX 7 + LPDDR3), same pinout | Targeted for factory automation and medical equipment requiring extended temperature reliability | Select for industrial environments where thermal derating of consumer-grade MC32PF3000A2EP is insufficient |
Compared with MC32PF3000A2EP, MC33PF3000A2ES and MC34PF3000A2EP share identical functionality and OTP programming but differ in temperature rating and qualification scope-making them direct drop-in replacements only when ambient conditions or regulatory requirements demand higher-grade operation.

FAQ
What is the primary target processor for MC32PF3000A2EP?
MC32PF3000A2EP is specifically configured for the NXP i.MX 7 application processor with LPDDR3 memory, as indicated by its OTP programming option "2" in Table 1. It delivers all required power rails-including VCORE, VDD_SOC, VREFDDR, and VCC_SD-with timing and voltage ranges aligned to i.MX 7 DVFS and memory interface specifications. The device is not preconfigured for i.MX 6SL/SX/UL variants unless reprogrammed via OTP.
Does MC32PF3000A2EP support dynamic voltage scaling (DVS)?
Yes, MC32PF3000A2EP supports DVS on its buck regulators (SW1A, SW1B, SW2, SW3) through programmable output voltage, PWM/PEM/APM mode selection, and soft-start ramp rate control (25 mV/2.0 μs or 25 mV/4.0 μs). This enables real-time core voltage adjustment during i.MX 7 processor load transitions, reducing dynamic power consumption without requiring external DACs or control logic.
How is the VREFDDR voltage generated and what is its accuracy?
MC32PF3000A2EP generates VREFDDR as 0.5 × SW3 output voltage, with a programmable SW3 range of 0.90–1.65 V-yielding VREFDDR = 0.45–0.825 V. The datasheet specifies VREFDDR output as 0.5–0.9 V, confirming internal trimming and regulation. It delivers 10 mA with dedicated pins (VREFDDR, VINREFDDR, VHALF) to ensure stability and noise immunity for DDR3L/LPDDR3 termination.
Can MC32PF3000A2EP operate with input voltages above 4.5 V?
Yes, MC32PF3000A2EP supports 3.7–5.5 V input via the VPWR pin when used with an external P-channel MOSFET as a front-end LDO. In this configuration, VIN is disconnected and VPWR supplies the internal regulators while the external FET drops excess voltage-ensuring internal rails remain within 4.5 V absolute maximum. Direct VIN connection is limited to 2.8–4.5 V.
Is MC32PF3000A2EP pin-compatible with other PF3000 variants like MC33PF3000A2ES?
Yes, MC32PF3000A2EP is pin-compatible with MC33PF3000A2ES and MC34PF3000A2EP-all use the identical 48-pin QFN package (98ASA00933D, 7.0 mm × 7.0 mm) and share identical pin functions, electrical characteristics, and OTP programming structure. The only differences are temperature grade (consumer vs. automotive vs. industrial) and part marking; no PCB redesign is needed when upgrading for environmental robustness.
