Product details
Overview
MC32PF3000A1EP from NXP Semiconductors is a pre-programmed power management IC (PMIC) optimized for i.MX 7 processors with DDR3L 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 full-system power for application processors, memory, and peripherals in space-constrained portable electronics.
For engineers reviewing the MC32PF3000A1EP datasheet, MC32PF3000A1EP pinout, MC32PF3000A1EP application, or MC32PF3000A1EP equivalent, this page provides verified regulator configurations, I²C-programmable startup sequencing, dynamic voltage scaling support, and OTP-based system-specific power tree initialization - all critical for i.MX 7 DDR3L platform bring-up and power validation.
Technical Context
The MC32PF3000A1EP implements a SMARTMOS-based multi-rail architecture with configurable SW1A/SW1B operation (independent 1.0 A / 1.75 A or combined 2.75 A), programmable PWM/PEM/APS switching modes, and hardware-assisted dynamic voltage scaling for ARM core rails. Its OTP memory stores startup sequence timing, voltage setpoints, and PWRON/RESETBMCU logic configuration - eliminating external configuration components.
It supports dual-input operation (VIN ≤ 4.5 V or VPWR 3.7–5.5 V with external PFET), includes dedicated VCC_SD with SD_VSEL-controlled dual-voltage output (1.8 V or 2.85–3.3 V), and integrates a 5.0–5.15 V, 600 mA boost regulator for USB OTG. The VREFDDR rail tracks 0.5 × SW3 output with ±1% accuracy for DDR3L compliance.

Pinout & Package
MC32PF3000A1EP uses a 48-pin QFN package (7.0 mm × 7.0 mm, wettable flank, 98ASA00933D), with exposed thermal pad (EP) tied to ground plane for thermal dissipation. Pin functions are validated per NXP PF3000 datasheet Rev. 10.1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INTB (Pin 1) | Open-drain fault interrupt output | Asserts low on overcurrent, undervoltage, or thermal fault - connects directly to i.MX 7 GPIO for real-time monitoring |
| SW1ALX (Pin 8) / SW1BLX (Pin 9) | Switch node outputs | Configurable for independent SW1A/SW1B operation or paralleled 2.75 A mode - requires proper inductor routing per mode |

FAQ
What is the OTP programming configuration for MC32PF3000A1EP?
MC32PF3000A1EP is factory-programmed for i.MX 7 processors with DDR3L memory. Its OTP memory defines the startup sequence, SW1A/SW1B combined mode (2.75 A), VREFDDR tracking ratio, and default I²C address (0x08). This eliminates runtime configuration and ensures deterministic power-up behavior specific to that SoC and memory combination.
Does MC32PF3000A1EP support DDR3L memory interfaces?
Yes, MC32PF3000A1EP explicitly supports DDR3L through its VREFDDR output (0.5 × SW3_OUT, ±1% accuracy) and SW3 buck regulator (0.9–1.65 V, 1.5 A), both configured in OTP to meet DDR3L VDDQ and reference voltage specifications. The datasheet confirms this configuration is validated for i.MX 7 with DDR3L.
Can MC32PF3000A1EP be used with i.MX 6UL processors?
No - MC32PF3000A1EP is OTP-programmed for i.MX 7 with DDR3L. For i.MX 6UL with DDR3L, use MC32PF3000A7EP; for i.MX 6UL with LPDDR2, use MC32PF3000A5EP. Using MC32PF3000A1EP with i.MX 6UL may result in incorrect voltage sequencing or unsupported regulator configurations.
What is the role of the SD_VSEL pin on MC32PF3000A1EP?
The SD_VSEL pin on MC32PF3000A1EP selects the output voltage range of the VCC_SD regulator: logic HIGH sets 1.80–1.85 V for UHS-I SD cards, while logic LOW sets 2.85–3.30 V for legacy SDIO interfaces. This hardware-selectable dual-voltage capability simplifies board design across multiple card types without firmware intervention.
Is MC32PF3000A1EP pin-compatible with other PF3000 variants?
Yes, all PF3000 variants including MC32PF3000A1EP share identical 48-pin QFN packaging, pinout, and register mapping. Differences are limited to OTP content (startup sequence, voltages, I²C address) and temperature grade - enabling drop-in replacement across consumer (MC32), automotive (MC33), and industrial (MC34) versions when thermal and qualification requirements align.
