Product details
Overview
MC32PF3001A2EPR2 from NXP Semiconductors is a pre-programmed Power Management IC (PMIC) optimized for i.MX 7 processors with LPDDR3 memory, delivering three buck regulators (SW1: 2.75 A, SW2: 1.25 A, SW3: 1.5 A), seven LDOs including VCC_SD (100 mA, dual-voltage SD card support), and RTC backup with coin cell charging. It operates from 2.8–4.5 V input and integrates I²C programmability, dynamic voltage scaling, and fixed OTP startup sequencing for embedded multimedia systems.
For engineers reviewing the MC32PF3001A2EPR2 datasheet, MC32PF3001A2EPR2 pinout, MC32PF3001A2EPR2 application, or MC32PF3001A2EPR2 equivalent, this page provides verified regulator output voltages, confirmed 48-pin QFN package mapping, validated I²C interface behavior, exact OTP configuration A2 startup parameters (SW1=1.10 V, SW2=1.8 V, SW3=1.2 V), and real-world power tree compatibility with i.MX 7 + LPDDR3 platforms.
Technical Context
The MC32PF3001A2EPR2 implements a fixed-OTP, non-reprogrammable power architecture with dedicated regulators mapped to i.MX 7 subsystems: SW1 supplies ARM Cortex-A7 cores (0.7–1.425 V), SW2 powers DDR I/O (1.5–1.85 V), and SW3 targets logic/memory domains (0.9–1.65 V). Its internal 32 kHz trimmed clock governs startup timing, while the 16 MHz RC oscillator drives switching frequency (2.0 MHz default) and DVS slew rate (12.5 mV/µs).
Control logic combines hardwired sequencing (OTP-configured startup order: SW1→SW2→SW3→V33→VCC_SD→VLDO4→VLDO1) with runtime flexibility via I²C register access for voltage adjustment, mode selection (PWM/PFM/APS), and fault monitoring. The VSNVS rail (3.0 V, 1.0 mA) operates independently for SNVS/SRTC retention, supported by integrated coin cell charge management on LICELL.

FAQ
What is the factory-programmed OTP configuration for MC32PF3001A2EPR2?
The MC32PF3001A2EPR2 is pre-programmed with OTP configuration A2, which sets SW1 to 1.10 V (for i.MX 7 Cortex-A7 cores), SW2 to 1.8 V (for DDR3L I/O), SW3 to 1.2 V (for logic domains), and defines startup sequence SW1→SW2→SW3→V33→VCC_SD→VLDO4→VLDO1. This configuration is permanently stored and cannot be modified in the field.
Does MC32PF3001A2EPR2 support both DDR3L and LPDDR3 memory interfaces?
Yes, MC32PF3001A2EPR2 is specifically configured for i.MX 7 with LPDDR3 memory, as indicated by its A2 OTP code. While the device can physically power DDR3L systems, the A2 configuration optimizes SW2 voltage (1.8 V) and timing for LPDDR3 I/O, making it the preferred choice for LPDDR3-based i.MX 7 designs per NXP's official documentation.
How does the VCC_SD regulator voltage selection work on MC32PF3001A2EPR2?
MC32PF3001A2EPR2's VCC_SD regulator outputs either 1.80–1.85 V or 2.85–3.30 V depending on the logic state of the SD_VSEL pin (Pin 2): LOW selects the higher range for standard SD cards, HIGH selects the lower range for 1.8 V SDIO interfaces. This hardware-controlled selection eliminates software overhead and ensures correct voltage before host initialization.
Can MC32PF3001A2EPR2 operate with a 5.0 V input supply?
Yes, MC32PF3001A2EPR2 supports 5.0 V input using the optional front-end VPWR LDO. Connect VPWR (Pin 31) to 5.0 V, populate an external PMOS pass FET (e.g., FDMA908PZ), and route LDOG (Pin 30) to its gate. VIN must then be connected to the FET drain, limiting internal regulator input to ≤4.5 V while maintaining full functionality.
What is the role of the LICELL pin on MC32PF3001A2EPR2?
The LICELL pin (Pin 36) on MC32PF3001A2EPR2 serves as a bidirectional coin cell interface: it charges a 3 V lithium coin cell when main power (VIN) is present, and automatically switches to supply the VSNVS rail (3.0 V, 1.0 mA) during main power loss. This ensures continuous RTC and SNVS domain operation without external circuitry.
