NXP Semiconductors MC32PF3001A5EPR2

Overview

MC32PF3001A5EPR2 from NXP Semiconductors is a pre-programmed Power Management IC (PMIC) optimized for i.MX 6 SoloLite 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/3.15 V output), 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. It enables full power sequencing for industrial embedded systems requiring DDR memory support and coin-cell-backed real-time clock operation.

For engineers reviewing the MC32PF3001A5EPR2 datasheet, MC32PF3001A5EPR2 pinout, MC32PF3001A5EPR2 application, or MC32PF3001A5EPR2 equivalent, key selection criteria include OTP-configured startup sequence (SW1_SEQ=1, SW2_SEQ=2, SW3_SEQ=4), fixed 2.0 MHz switching frequency, I²C programmability, and compatibility with 2.8–4.5 V input rails-critical for set-top box, POS terminal, and industrial control designs where regulated core, I/O, and memory voltages must meet i.MX 6SL timing and voltage tolerance requirements.

Technical Context

The MC32PF3001A5EPR2 implements a fixed OTP-based power tree with hardwired sequencing: SW1 powers the ARM core (1.375 V), SW2 supplies I/O domains (3.15 V), and SW3 targets DDR memory (1.2 V), all synchronized to a trimmed 32 kHz clock. Its architecture integrates dynamic voltage scaling (DVS) on SW1/SW2/SW3, programmable PFM/PWM/APS modes, and an optional front-end VPWR LDO using external PMOS for >4.5 V inputs.

Control logic combines dedicated hardware signals (PWRON, RESETBMCU, INTB, SD_VSEL) with I²C register access for runtime adjustment of output voltages and fault monitoring. The device uses internal bandgap references (VCOREREF) and separate ground references (GNDREF1/GNDREF2/GNDREF) to isolate analog, digital, and switching regulator return paths-ensuring stability in noise-sensitive multimedia applications.

FAQ

What is the default I²C address for MC32PF3001A5EPR2?

The default I²C slave address for MC32PF3001A5EPR2 is 0x08, as specified in Table 4 of the PF3001 datasheet Rev. 5.1. This address is fixed across all PF3001 variants including MC32PF3001A5EPR2 and cannot be altered via OTP or runtime configuration. Communication requires standard I²C protocol with SDA/SCL pulled up to VDDIO (1.7–3.6 V) using 4.7 kΩ resistors. MC32PF3001A5EPR2 supports read/write access to voltage, mode, and fault registers once powered and initialized.

How does the SD_VSEL pin affect VCC_SD output voltage in MC32PF3001A5EPR2?

In MC32PF3001A5EPR2, the SD_VSEL pin (Pin 2) directly selects the VCC_SD regulator output: logic LOW configures 3.15 V for SDIO 3.0 compliance, while logic HIGH sets 1.80 V for legacy SD card operation. This selection is hardware-based and overrides any I²C register setting. The SD_VSEL buffer is powered by VDDIO; if VDDIO is absent, the pin defaults to HIGH, forcing 1.80 V output. MC32PF3001A5EPR2's OTP A5 configuration supports both ranges without firmware intervention.

What is the startup sequence order for MC32PF3001A5EPR2?

MC32PF3001A5EPR2 implements a fixed OTP A5 startup sequence: SW1 (1.375 V) → SW2 (3.15 V) → VCC_SD (3.15 V or 1.80 V) → VLDO4 → SW3 (1.2 V), with SEQ_CLK_SPEED = 2000 µs between stages. This ordering ensures i.MX 6 SoloLite core power is established before memory and I/O rails, preventing bus contention. RESETBMCU deasserts 2.0 ms after SW3 enable. MC32PF3001A5EPR2 does not allow runtime modification of this sequence-it is permanently programmed in OTP memory.

Can MC32PF3001A5EPR2 operate with a 5.0 V input supply?

Yes, MC32PF3001A5EPR2 can operate with a 5.0 V input using the optional front-end VPWR LDO: connect VPWR to 5.0 V, populate an external PMOS (e.g., FDMA908PZ), and route LDOG to its gate. VIN must then be driven from the PMOS source. This configuration limits internal regulator input to ≤4.5 V. Direct 5.0 V connection to VIN is prohibited and will damage MC32PF3001A5EPR2. For ≤4.5 V inputs, VPWR is grounded and VIN is used directly-verified in MC32PF3001A5EPR2's 2.8–4.5 V specification.

What is the purpose of the VSNVS rail in MC32PF3001A5EPR2?

The VSNVS rail in MC32PF3001A5EPR2 provides a dedicated 3.0 V, 1.0 mA always-on supply for the Secure Non-Volatile Storage (SNVS) and Real-Time Clock (RTC) domains of i.MX 6 SoloLite processors. It remains active during system sleep and main power loss, supported by coin-cell backup via the LICELL pin. MC32PF3001A5EPR2 integrates charging circuitry to maintain the coin cell, ensuring RTC timekeeping and secure key storage continuity-critical for medical and industrial applications requiring timestamped event logging.
