Product details
Overview
MC32PF3001A6EPR2 from NXP Semiconductors is a pre-programmed Power Management IC (PMIC) optimized for i.MX 6UL processors with LPDDR2 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 1.8 V/3.3 V), V33 (350 mA), and VSNVS (1.0 mA RTC supply)-in a 48-pin QFN 7.0 mm × 7.0 mm wettable flank package. It enables full power sequencing for industrial embedded systems requiring DDR3L/LPDDR2 memory support.
For engineers reviewing the MC32PF3001A6EPR2 datasheet, MC32PF3001A6EPR2 pinout, MC32PF3001A6EPR2 application, or MC32PF3001A6EPR2 equivalent, key selection criteria include OTP-configured startup sequence (SW1_SEQ=3, SW2_SEQ=3, SW3_SEQ=3), fixed 2.0 MHz switching frequency, I²C programmability, and support for coin-cell backup in always-on SNVS domains.
Technical Context
The MC32PF3001A6EPR2 implements a fixed OTP-based power tree with hardwired sequencing logic: SW1 powers the i.MX 6UL core at 1.4 V (VDD_ARM), SW2 supplies I/O rails (e.g., NVCC_GPIOx, VDDA_1P8) at 3.3 V, and SW3 delivers memory voltage (e.g., NVCC_DRAM_CKE) at 1.2 V. All buck regulators support APS/PWM/PFM modes and dynamic voltage scaling via I²C register writes to SWxVOLT[4:0].
Its internal architecture integrates a trimmed 16 MHz RC oscillator for regulator switching clock generation and a 32 kHz reference for startup timing control; the VSNVS rail operates as an LDO or bypass switch powered by VIN or coin cell; VPWR front-end LDO support requires external PMOS (e.g., FDMA908PZ) for >4.5 V input operation.
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 PMOS) |
| SW1 Output | 1.4 V @ 2.75 A - configured for i.MX 6UL core (VDD_ARM) per OTP A6 |
| SW2 Output | 3.3 V @ 1.25 A - powers GPIO, I/O, and peripheral rails |
| SW3 Output | 1.2 V @ 1.5 A - supplies LPDDR2 memory interface |
| VCC_SD Output | 1.85 V / 3.3 V selectable via SD_VSEL pin - supports SD card interface compliance |
| VSNVS Output | 3.0 V @ 1.0 mA - dedicated always-on supply for SNVS/SRTC domain with coin-cell charging |
| I²C Address | 0x08 default - enables runtime configuration of voltage, DVS slope (6.25 mV/µs), and fault masking |
Pinout & Package
MC32PF3001A6EPR2 uses a 48-pin QFN 7.0 mm × 7.0 mm wettable flank (WF-type) package (98ASA00933D), with exposed thermal pad (EP) tied to ground plane for thermal dissipation. Pin functions are defined per NXP PF3001 Rev. 5.1 datasheet Section 7.2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW1IN / SW1FB / SW1LX (pins 7,6,8–9) | Buck 1 power path | SW1IN accepts main input; SW1FB provides feedback for 1.4 V regulation; SW1LX connects to external 1.5 µH inductor |
| SW2IN / SW2FB / SW2LX (pins 18,19,17) | Buck 2 power path | Configured for 3.3 V output; SW2FB routing must be isolated from high-current paths for stable regulation |
| SW3IN / SW3FB / SW3LX (pins 28,27,29) | Buck 3 power path | Delivers 1.2 V to LPDDR2; SW3FB trace termination near load improves transient response |
| VCC_SD / V33 / VLDO4 (pins 33,32,22) | LDO outputs | VCC_SD supports SDIO voltage select; V33 powers 3.3 V peripherals; VLDO4 supplies 350 mA for high-current I/O rails |
| SDA / SCL / VDDIO (pins 45–47) | I²C interface | Open-drain SDA/SCL pulled to VDDIO (1.7–3.6 V); VDDIO must ≤ VIN for safe level-shifting |
| INTB / RESETBMCU / PWRON (pins 1,3,48) | Control signals | INTB asserts on fault (e.g., overvoltage, thermal); RESETBMCU deasserts 2 ms after final regulator enable; PWRON initiates startup |
Key Features
| Feature | Design Value |

FAQ
What is the default I²C address for MC32PF3001A6EPR2?
The default I²C address for MC32PF3001A6EPR2 is 0x08, as specified in Table 4 of the PF3001 datasheet Rev. 5.1. This address is factory-trimmed and cannot be altered; all runtime configuration-including SW1 voltage adjustment, DVS slope setting, and fault interrupt masking-is performed via this fixed address. MC32PF3001A6EPR2 does not support address pins or software-configurable addressing.
How does MC32PF3001A6EPR2 support i.MX 6UL with LPDDR2 memory?
MC32PF3001A6EPR2 supports i.MX 6UL with LPDDR2 through its OTP A6 configuration: SW3 delivers 1.2 V @ 1.5 A to NVCC_DRAM_CKE, SW1 supplies 1.4 V @ 2.75 A to VDD_ARM, and SW2 provides 3.3 V @ 1.25 A to VDDA_1P8 and GPIO rails. Startup sequencing (SW1_SEQ=3, SW2_SEQ=3, SW3_SEQ=3) aligns with i.MX 6UL LPDDR2 initialization timing requirements per NXP AN5307.
Can MC32PF3001A6EPR2 operate with a 5.0 V input supply?
Yes, MC32PF3001A6EPR2 can operate with a 5.0 V input supply using the VPWR front-end LDO: connect VPWR to 5.0 V, populate an external PMOS (e.g., FDMA908PZ), and tie LDOG to the gate. The internal error amplifier regulates VIN to ≤4.5 V, protecting downstream regulators. If input is ≤4.5 V, use VIN directly and ground VPWR-no external FET required.
What is the purpose of the SD_VSEL pin on MC32PF3001A6EPR2?
The SD_VSEL pin on MC32PF3001A6EPR2 selects the output voltage range of the VCC_SD regulator: logic high sets 1.80–1.85 V for SDIO 3.0/4.0 UHS-I mode; logic low sets 2.85–3.30 V for legacy SD cards. This hardware-selectable dual-voltage capability eliminates need for external level shifters and ensures compliance with JEDEC JESD84-B51 specifications.
Does MC32PF3001A6EPR2 include battery backup functionality?
Yes, MC32PF3001A6EPR2 includes integrated battery backup functionality via the VSNVS rail and LICELL pin: VSNVS provides a regulated 3.0 V @ 1.0 mA always-on supply for the i.MX SNVS domain, and LICELL supports charging of external coin cells (e.g., CR2032) with current limiting and end-of-charge detection-enabling RTC retention and secure key storage during main power loss.
