Product details
Overview
MC32PF3000A8EPR2 from NXP Semiconductors is a power management IC (PMIC) engineered for i.MX 6UL application processors with DDR3 memory, delivering four buck regulators (SW1A: 1.0 A, SW1B: 1.75 A, SW2: 1.25 A, SW3: 1.5 A), six LDOs including V33 (350 mA) and VCC_SD (100 mA), RTC supply (VSNVS, 3.0 V), DDR reference (VREFDDR, 0.5×SW3_OUT), and coin-cell charging - enabling full-system power for industrial embedded designs.
For engineers reviewing the MC32PF3000A8EPR2 datasheet, MC32PF3000A8EPR2 pinout, MC32PF3000A8EPR2 application, or MC32PF3000A8EPR2 equivalent, key selection criteria include its -40 °C to 85 °C industrial temperature rating, OTP-programmable startup sequence, I²C-configurable voltage rails, and support for dynamic voltage scaling on core buck regulators in consumer- and industrial-grade i.MX 6UL platforms.
Technical Context
The MC32PF3000A8EPR2 implements a multi-rail architecture with configurable SW1A/SW1B pairing (independent or combined 2.75 A), programmable PWM/PPM/APS switching modes, and integrated OTP memory storing startup timing, voltage setpoints, and I²C address (0x08–0x0F). Its control logic supports direct hardware sequencing via PWRON, STANDBY, and RESETBMCU signals alongside I²C register-level real-time adjustment.
It features dedicated analog blocks: VREFDDR generation referenced to SW3 output, VSNVS as either 3.0 V LDO or bypass switch for SNVS domain, and VPWR front-end LDO support using external P-MOSFET for >4.5 V input systems. All regulators include soft-start, current limiting, and feedback-based regulation with separate ground references (GNDREF1/GNDREF2/GNDREF) for noise isolation.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 INTB | Open-drain interrupt output | Asserts low on fault (OCP, UVLO, thermal); requires external pull-up for processor alert signaling |
| 2 SD_VSEL | Digital input | Selects VCC_SD output: HIGH = 1.80–1.85 V (SD card), LOW = 2.85–3.30 V (general I/O) |
| 3 RESETBMCU | Open-drain reset output | Deasserts 2.0 ms after last regulator enables; configurable for fault-monitoring mode |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC33PF3000A7ES | Automotive-grade (-40 °C to 105 °C), same 48-QFN package and OTP programming model | Qualified for AEC-Q100 Grade 2; includes enhanced watchdog and fault reporting for safety-critical systems | Select when automotive qualification, extended temperature, or ASIL-B support is required - not drop-in due to different OTP configuration and thermal specs |
| MC34PF3000A8ES | Industrial-grade (-40 °C to 105 °C), identical feature set and pinout, but higher max junction temperature rating | Supports more thermally demanding enclosures; shares same i.MX 6UL DDR3 programming option (A8) | Choose for industrial deployments above 85 °C ambient - requires validation of thermal margin and OTP reprogramming for target board |
Compared with MC32PF3000A8EPR2, MC33PF3000A7ES adds automotive qualification and fault diagnostics at the cost of higher BOM complexity, while MC34PF3000A8ES extends thermal capability without altering functional behavior - both require OTP reconfiguration and thermal layout review for replacement.

FAQ
What is the operating temperature range for MC32PF3000A8EPR2?
MC32PF3000A8EPR2 is rated for -40 °C to +85 °C operation, qualifying it for industrial applications where extended ambient temperature stability is required. This range is defined in Table 1 of the PF3000 datasheet and applies specifically to the MC32 prefix variant. The device uses SMARTMOS technology to maintain regulation accuracy and startup reliability across this full span without derating.
How does MC32PF3000A8EPR2 support i.MX 6UL with DDR3 memory?
MC32PF3000A8EPR2 supports i.MX 6UL with DDR3 via its A8 OTP programming option, which configures SW2 for 2.50–3.30 V output (for DDR3 I/O), SW3 for 0.90–1.65 V (core), and VREFDDR to track 0.5×SW3_OUT. The part's pinout and startup sequence are optimized for this configuration, matching the power tree in Figure 4 of the datasheet.
Can MC32PF3000A8EPR2 be used with input voltages above 4.5 V?
Yes - MC32PF3000A8EPR2 supports 3.7–5.5 V input via the VPWR pin when paired with an external P-MOSFET configured as a front-end LDO. The internal regulators remain protected at ≤4.5 V. This configuration requires connecting VPWR to the FET drain and VIN to the regulated output, as specified in Section 8.2 of the datasheet.
What is the role of the SD_VSEL pin on MC32PF3000A8EPR2?
The SD_VSEL pin on MC32PF3000A8EPR2 selects the output voltage range of the VCC_SD LDO: logic HIGH sets 1.80–1.85 V for high-speed SD cards, while logic LOW sets 2.85–3.30 V for general-purpose I/O. Its input buffer is powered by VDDIO, and defaults to HIGH if VDDIO is absent - ensuring safe default behavior during power-up.
Does MC32PF3000A8EPR2 include battery backup capability?
Yes - MC32PF3000A8EPR2 integrates a coin-cell charger and VSNVS regulator/switch that delivers 3.0 V at 1.0 mA. When a coin cell is connected to LICELL, it powers the SNVS domain during main power loss, preserving RTC time and secure non-volatile state - critical for industrial logging and secure boot applications.
