Product details
Overview
MC32PF3000A4EPR2 from NXP Semiconductors is a power management IC (PMIC) engineered for i.MX 6SX application processors with DDR3 memory, delivering four buck regulators (SW1A/B up to 2.75 A combined, SW2 at 1.25 A, SW3 at 1.5 A), six LDOs including V33 (350 mA) and VCC_SD (100 mA), RTC supply (VSNVS, 3.0 V), DDR reference (VREFDDR, 0.5–0.9 V), and I²C programmability - enabling full-system power delivery in compact industrial edge devices.
For engineers reviewing the MC32PF3000A4EPR2 datasheet, MC32PF3000A4EPR2 pinout, MC32PF3000A4EPR2 application, or MC32PF3000A4EPR2 equivalent, this page delivers verified regulator configurations, OTP-programmed startup sequence for i.MX 6SX+DDR3, wettable-flank QFN-48 package details, and real-world design implications of dynamic voltage scaling, coin-cell backup, and VPWR front-end LDO support.
Technical Context
The MC32PF3000A4EPR2 implements SMARTMOS technology with OTP-configured power sequencing optimized for i.MX 6SX + DDR3 systems. Its dual-mode SW1A/SW1B architecture supports either independent operation (1.0 A / 1.75 A) or parallel configuration (2.75 A), while SW2 and SW3 provide programmable output voltages (1.50–1.85 V or 2.50–3.30 V; 0.90–1.65 V) with dynamic voltage scaling across PWM/PEM/APS modes.
Control logic integrates I²C (address 0x08–0x0F), level- or edge-triggered PWRON, active-low STANDBY, open-drain RESETBMCU and INTB, plus SD_VSEL for VCC_SD voltage selection (1.8 V or 2.85–3.3 V). The device uses internal bandgap references (VCOREREF), GNDREF1/GNDREF2 isolation, and dedicated DDR reference generation (VREFDDR = 0.5 × SW3_OUT) with 10 mA drive capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.8–4.5 V (VIN) or 3.7–5.5 V (VPWR via external PFET) - enables flexible system-level input sourcing |
| Buck Regulator Count | 4 channels (SW1A/B configurable as 1×2.75 A or 2×independent; SW2: 1.25 A; SW3: 1.5 A) - powers CPU core, SOC logic, DDR IO, and peripherals |
| LDO Count & Output | 6 LDOs: V33 (350 mA, 2.85–3.3 V), VCC_SD (100 mA, dual-range), VLDO2 (250 mA, 0.8–1.55 V), VLDO4 (350 mA), VSNVS (1 mA, 3.0 V), VREFDDR (10 mA, 0.5–0.9 V) |
| I²C Interface | Configurable slave address (0x08–0x0F), open-drain SDA/SCL with 4.7 kΩ pull-up - supports multi-device bus integration without conflict |
| OTP Memory | One-time programmable storage for startup sequence, regulator voltages, PWRON mode, RESETBMCU behavior, and I²C address - eliminates external configuration components |
| Package | 48-pin QFN, 7.0 mm × 7.0 mm, wettable flank (98ASA00933D) - supports automated optical inspection and high thermal reliability in industrial PCBs |
Pinout & Package
MC32PF3000A4EPR2 uses a 48-pin wettable flank QFN (98ASA00933D, 7.0 mm × 7.0 mm) with exposed thermal pad (EP) tied to ground plane for thermal dissipation. Pin functions are validated per NXP PF3000 Rev. 10.1 datasheet Section 7.2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INTB (Pin 1) | Open-drain fault interrupt output | Asserts low on overcurrent, undervoltage, or thermal fault - requires external pull-up for host processor notification |
| SW1ALX (Pin 8) & SW1BLX (Pin 9) | Switch node outputs | Connect to inductor(s) - shared when SW1A/B operate in parallel; isolated when independent |
| VIN (Pin 42) & VPWR (Pin 31) | Main and front-end LDO inputs | VIN used for ≤4.5 V supplies; VPWR + external PFET required for 3.7–5.5 V input to protect internal regulators |
| VREFDDR (Pin 25) & VINREFDDR (Pin 24) | DDR reference output & input | VREFDDR = 0.5 × SW3 output voltage; VINREFDDR must be bypassed with 0.1 μF to VHALF (Pin 23) for accuracy |
| SDA (Pin 45) & SCL (Pin 46) | I²C data and clock | Open-drain interface - VDDIO (Pin 47) must be 1.7–3.6 V and ≤ VIN for proper logic level translation |
Key Features
| Feature | Design Value |
|---|---|
| Configurable SW1A/SW1B topology | Single 2.75 A rail or dual independent rails (1.0 A + 1.75 A) - adapts to i.MX 6SX core voltage and current demands |
| OTP-programmed startup sequence | 15-slot timing with 0.5 ms or 2.0 ms step resolution - ensures deterministic power-up order for DDR3 initialization and processor boot |
| Dual-range VCC_SD regulator | 1.8 V (SD_VSEL = HIGH) or 2.85–3.3 V (SD_VSEL = LOW) - matches SD card interface voltage requirements without external switching |
| VSNVS always-on supply | 3.0 V, 1.0 mA output with coin-cell backup - maintains secure non-volatile storage and real-time clock during main power loss |
| VPWR front-end LDO support | External PFET-based LDO for >4.5 V inputs - extends usable input range to 5.5 V while preserving internal regulator safety margins |

FAQ
What is the OTP programming configuration for MC32PF3000A4EPR2?
MC32PF3000A4EPR2 is pre-programmed for i.MX 6SX with DDR3 memory, as indicated by the "A4" code in its part number. This includes fixed startup sequence timing, SW1A/SW1B parallel mode, VREFDDR derivation from SW3, and I²C address 0x08. Configuration details are defined in Table 10 of the PF3000 datasheet Rev. 10.1.
Does MC32PF3000A4EPR2 support coin-cell backup for RTC operation?
Yes, MC32PF3000A4EPR2 includes a dedicated VSNVS regulator (3.0 V, 1.0 mA) with LICELL pin (Pin 36) supporting coin-cell input/output. When main power fails, VSNVS maintains power to the i.MX 6SX's SNVS domain, preserving RTC time, secure keys, and tamper-detection circuitry without interruption.
What package type and thermal characteristics does MC32PF3000A4EPR2 use?
MC32PF3000A4EPR2 uses a 48-pin wettable flank QFN (98ASA00933D, 7.0 mm × 7.0 mm) with exposed thermal pad (EP). This package enables reliable automated optical inspection and efficient heat dissipation - critical for sustained operation in industrial enclosures where ambient temperatures reach 85°C.
Can MC32PF3000A4EPR2 operate with a 5 V input supply?
Yes, MC32PF3000A4EPR2 supports 3.7–5.5 V input via the VPWR pin (Pin 31) when used with an external P-channel MOSFET as a front-end LDO. This configuration limits internal regulator input to ≤4.5 V, protecting SW1A/B, SW2, and SW3 while enabling direct 5 V system rail integration.
How does the SD_VSEL pin affect MC32PF3000A4EPR2 operation?
The SD_VSEL pin (Pin 2) selects VCC_SD output voltage: logic HIGH yields 1.8 V to 1.85 V; logic LOW yields 2.85 V to 3.3 V. This allows MC32PF3000A4EPR2 to dynamically match SD card interface voltage requirements - essential for interoperability with both legacy and UHS-I SD hosts without external level-shifting circuitry.
