Product details
Overview
MC32PF3000A6EPR2 from NXP Semiconductors is a power management IC (PMIC) engineered for the i.MX 6UL application processor with LPDDR2 memory, delivering four buck regulators (SW1A: 1.0 A, SW1B: 1.75 A, SW2: 1.25 A, SW3: 1.5 A), six LDOs, VREFDDR reference, RTC supply (VSNVS: 3.0 V, 1.0 mA), and coin-cell charging-enabling full-system power for industrial embedded designs.
For engineers reviewing the MC32PF3000A6EPR2 datasheet, MC32PF3000A6EPR2 pinout, MC32PF3000A6EPR2 application, or MC32PF3000A6EPR2 equivalent, this device supports I²C-programmable startup sequencing, dynamic voltage scaling (DVS), OTP-configurable PWRON/RESETBMCU logic, and dual-voltage VCC_SD regulation-critical for low-power, high-reliability i.MX 6UL-based edge controllers and HMI terminals.
Technical Context
The MC32PF3000A6EPR2 implements SMARTMOS technology to integrate four synchronous buck converters, one boost regulator (SWBST: 5.0–5.15 V, 600 mA), seven LDOs (including VCC_SD with SD_VSEL-selectable 1.8 V/3.3 V output), and DDR reference generation (VREFDDR = 0.5 × SW3_OUT). Its OTP memory stores startup sequence timing, voltage setpoints, and mode configuration-eliminating external resistive programming.
Control logic includes dedicated I²C interface (address programmable 0x08–0x0F), open-drain interrupt (INTB), reset output (RESETBMCU), standby input (STANDBY), and power-on trigger (PWRON) with configurable edge/level detection and hardware debouncing (up to 750 ms). The device operates across 2.8–4.5 V (VIN) or 3.7–5.5 V (VPWR) input ranges and supports user-defined Standby, Sleep/LPSR, and Off modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.8–4.5 V (VIN) or 3.7–5.5 V (VPWR); enables direct battery or adapter input without external front-end regulation in most cases |
| Buck Regulator Count & Max Current | 4 channels: SW1A (1.0 A), SW1B (1.75 A), SW2 (1.25 A), SW3 (1.5 A); supports core, SOC, I/O, and DDR rail generation |
| LDO Count & Key Outputs | 6 LDOs: VCC_SD (1.8/3.3 V, 100 mA), V33 (3.3 V, 350 mA), VLDO2 (0.8–1.55 V, 250 mA), VLDO4 (1.8–3.3 V, 350 mA), VSNVS (3.0 V, 1.0 mA), VREFDDR (0.5×SW3_OUT, 10 mA) |
| Dynamic Voltage Scaling | Supported on SW1A, SW1B, SW2, SW3 via programmable soft-start ramp (25 mV/2 µs or 4 µs) and PWM/PFM/APS mode selection |
| I²C Interface | Standard-mode (100 kHz) and fast-mode (400 kHz) compatible; slave address programmable from 0x08 to 0x0F to avoid bus conflicts |
| OTP Memory | One-time programmable storage for startup sequence order, regulator voltages, PWRON_CFG, RESETBMCU mode, and I²C address-enables board-level customization without firmware dependency |
Pinout & Package
MC32PF3000A6EPR2 uses a 48-pin QFN package (7.0 mm × 7.0 mm, wettable flank, 98ASA00933D), optimized for thermal dissipation and automated optical inspection. The exposed pad (EP) must be connected to ground planes via multiple vias.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INTB | Open-drain interrupt output | Asserts low on fault (OCP, UVLO, thermal); requires external pull-up; used for system-level fault monitoring |
| RESETBMCU | Open-drain reset output | Deasserts 2.0 ms after last regulator enables (default) or only if no startup faults occur (OTP-configurable fault mode) |
| PWRON | Power-on control input | Configurable as level- or edge-sensitive; supports mechanical switch debounce (31.25–750 ms) for reliable turn-on in industrial environments |
| SD_VSEL | Digital select input | Switches VCC_SD output between 1.8 V/1.85 V (SD_VSEL = HIGH) and 2.85 V/3.3 V (SD_VSEL = LOW) for SD card interface compatibility |
| SCL / SDA | I²C clock/data lines | Enable real-time reconfiguration of regulators, DVS, and mode transitions; require 4.7 kΩ pull-ups to VDDIO (1.7–3.6 V) |
| VIN / VPWR | Main power inputs | VIN accepts ≤4.5 V directly; VPWR enables use of external PFET LDO for >4.5 V inputs-ensures safe operation across wide input range |
Key Features
| Feature | Design Value |
|---|---|
| OTP-configurable startup sequence | Each regulator assigned to slot 1–15 with 0.5 ms or 2.0 ms inter-slot delay; eliminates need for external sequencer ICs or complex timing circuits |
| SW1A/SW1B flexible configuration | Operates as independent 1.0 A + 1.75 A regulators or combined 2.75 A single-phase output-adapts to i.MX 6UL core voltage and current demands |
| VREFDDR generation | Derives DDR reference from SW3 output (VREFDDR = 0.5 × SW3_OUT); ensures tight tracking and stability for LPDDR2 memory interfaces |
| VSNVS always-on supply | 3.0 V, 1.0 mA regulated output powered from VIN or coin cell; maintains SNVS domain during deep sleep-enables RTC and secure boot persistence |
| Integrated coin-cell charger | LICELL pin supports trickle charge and backup switching; allows seamless transition to coin-cell power during main supply loss-critical for data logging and timekeeping |

FAQ
What is the operating temperature range for MC32PF3000A6EPR2?
MC32PF3000A6EPR2 is rated for operation from -40 °C to +85 °C ambient temperature, making it suitable for commercial and industrial indoor applications. This specification aligns with the "Consumer applications" qualification noted in the official ordering information table for the MC32 prefix variant. For extended-temperature requirements up to 105 °C, the MC34PF3000A6ES variant is recommended.
How does MC32PF3000A6EPR2 support i.MX 6UL with LPDDR2 memory?
MC32PF3000A6EPR2 supports i.MX 6UL with LPDDR2 through its OTP-programmed configuration option "6", which sets SW3 output (0.9–1.65 V) and VREFDDR (0.5 × SW3_OUT) to match LPDDR2 VDDQ and reference voltage requirements. The device also supplies core (SW1A/B), SOC (SW2), and I/O (V33, VCC_SD) rails per i.MX 6UL power tree specifications.
Can MC32PF3000A6EPR2 be used without OTP programming?
Yes-MC32PF3000A6EPR2 supports Try-Before-Buy (TBB) mode, where regulators start using values loaded into TBBOTP registers instead of fused OTP settings. This allows functional validation and sequence tuning via I²C before final OTP programming, reducing development risk and enabling rapid prototyping without committing to permanent fuse settings.
What is the purpose of the SD_VSEL pin on MC32PF3000A6EPR2?
The SD_VSEL pin on MC32PF3000A6EPR2 selects the output voltage range of the VCC_SD LDO: logic HIGH configures 1.8 V to 1.85 V for UHS-I SD cards, while logic LOW configures 2.85 V to 3.30 V for legacy SD/SDIO devices. This dual-voltage capability ensures interoperability across SD card generations without external level-shifting circuitry.
Does MC32PF3000A6EPR2 include battery backup capability?
Yes-MC32PF3000A6EPR2 integrates a dedicated coin-cell charging and switchover circuit via the LICELL pin, supporting backup power for the VSNVS rail (3.0 V, 1.0 mA). This maintains RTC operation and secure non-volatile storage during main supply interruption, fulfilling critical requirements for data loggers, gateways, and secure boot applications.
