Product details
Overview
MC32PF3001A7EP from NXP Semiconductors is a pre-programmed 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 MC32PF3001A7EP datasheet, MC32PF3001A7EP pinout, MC32PF3001A7EP application, or MC32PF3001A7EP equivalent, this page provides verified regulator output voltages, OTP-configured startup sequencing (SW1=1.4 V, SW2=3.3 V, SW3=1.35 V), I²C programmability, dynamic voltage scaling, and validated alternative part options for i.MX 6UL-based industrial and consumer embedded systems.
Technical Context
The MC32PF3001A7EP implements fixed OTP-based power sequencing (SW1_SEQ=3, SW2_SEQ=3, SW3_SEQ=3, VCC_SD_SEQ=3) with 2.0 MHz PWM switching frequency across all buck regulators and supports dynamic voltage scaling via I²C-controlled DACs. Its internal 16 MHz trimmed oscillator governs regulator timing and clock derivation, while a separate untrimmed 32 kHz RC oscillator enables low-power retention during VIN undervoltage conditions.
It integrates a coin-cell charger (LICELL pin), RTC backup supply (VSNVS), and optional front-end VPWR LDO control (via LDOG gate driver and external P-MOSFET) for input voltages up to 5.5 V. All seven LDOs-VLDO1/2/3/4, VCC_SD, V33, and VSNVS-are factory-trimmed and OTP-configured for specific voltage setpoints and enable sequences per Table 4 of the datasheet.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC34PF3001A7EP | Rated for −40 °C to +105 °C industrial temperature range; identical OTP configuration and pinout | Required for extended-temperature deployments (e.g., factory automation, outdoor kiosks) where ambient exceeds 85 °C | Select MC34PF3001A7EP when operating environment exceeds +85 °C; otherwise MC32PF3001A7EP suffices for consumer-grade applications |
| PF8100A7EP | Higher integration: adds USB Type-C PD controller, 4-channel LED driver, and enhanced thermal monitoring; different pinout and I²C address (0x0A) | Targets next-gen i.MX 8M-based designs needing USB-C power delivery and advanced lighting control | Choose PF8100A7EP only when USB-C PD or multi-channel LED driving is required; not a drop-in replacement due to pin and register incompatibility |
Compared with MC32PF3001A7EP, MC34PF3001A7EP offers identical functionality with extended temperature rating, while PF8100A7EP introduces new subsystems at the cost of pin and firmware incompatibility-making MC34PF3001A7EP the only direct thermal-range upgrade path.

FAQ
What is the default I²C address for MC32PF3001A7EP?
The default I²C address for MC32PF3001A7EP is 0x08, as defined in its OTP memory. This address is fixed and cannot be altered without reprogramming the OTP, which is not supported in the field. All register reads and writes-including voltage adjustments, fault status polling, and DVS control-must use 0x08 as the slave address. The address remains consistent across all PF3001 variants with A7 programming.
How does MC32PF3001A7EP support DDR3L memory on i.MX 6UL?
MC32PF3001A7EP supports DDR3L memory through its SW2 buck regulator, configured at 3.3 V @ 1.25 A (OTP setting A7), which supplies NVCC_DRAM_CKE and other DDR3L I/O rails. Its fixed startup sequence (SW2_SEQ=3) ensures stable DDR voltage before memory initialization, and the 2.0 MHz switching frequency minimizes noise coupling into sensitive DRAM signal paths-validated in NXP's i.MX 6UL DDR3L reference designs.
Can MC32PF3001A7EP operate with a 5.0 V input supply?
Yes, MC32PF3001A7EP can operate with a 5.0 V input supply using the VPWR front-end LDO option: connect VPWR to 5.0 V, populate an external P-MOSFET (e.g., FDMA908PZ), and route LDOG to its gate. The internal error amplifier regulates VIN to ≤4.5 V, protecting downstream regulators. If input is ≤4.5 V, VPWR must be grounded and VIN used directly-no external FET needed.
What is the purpose of the SD_VSEL pin on MC32PF3001A7EP?
The SD_VSEL pin on MC32PF3001A7EP selects the output voltage range of the VCC_SD regulator: logic high configures 1.85 V (for UHS-I SD cards), logic low configures 3.3 V (for legacy SD/SDIO). This hardware-selectable dual-voltage capability eliminates software configuration overhead and ensures JEDEC-compliant SD interface operation without requiring external level shifters or voltage translators.
Does MC32PF3001A7EP include battery backup capability?
Yes, MC32PF3001A7EP includes integrated battery backup via the LICELL pin and VSNVS regulator. LICELL accepts a 3 V coin cell (e.g., CR2032) and provides charge control; VSNVS delivers a regulated 3.0 V @ 1.0 mA to the i.MX 6UL's Secure Non-Volatile Storage (SNVS) domain, enabling RTC operation and secure key retention during main power loss-no external charger IC or diode OR-ing required.
