Product details
Overview
MC32PF1510A3EPR2 from NXP Semiconductors is a preprogrammed power management IC (PMIC) optimized for i.MX 6UL processors with DDR3L memory, delivering three 1.0 A buck converters (SW1–SW3), three LDOs (LDO1–LDO3), VSNVS RTC supply (3.0 V/2.0 mA), DDR reference (VREFDDR, 0.5–0.9 V/10 mA), and I²C programmability. It supports low-power IoT and wearable systems requiring tight voltage sequencing and dynamic voltage scaling.
For engineers reviewing the MC32PF1510A3EPR2 datasheet, MC32PF1510A3EPR2 pinout, MC32PF1510A3EPR2 application, or MC32PF1510A3EPR2 equivalent, this page provides verified technical context, validated pin functions, confirmed regulator output ranges and accuracy, thermal ratings for industrial operation (−40 °C to 105 °C), and real-world alternative selection guidance aligned with i.MX 6UL DDR3L system requirements.
Technical Context
The MC32PF1510A3EPR2 implements a dedicated OTP-programmed configuration for i.MX 6UL with DDR3L, embedding fixed startup/power-down sequences, DVS-enabled SW1/SW2 (0.6–1.3875 V in 12.5 mV steps), and SW3 fixed at 1.8–3.3 V. Its front-end LDO accepts 4.1–6.0 V input and withstands up to +22 V transients, feeding VSYS to all internal regulators.
Regulator control uses an integrated digital core with I²C interface (SCL/SDA), open-drain interrupt (INTB) and reset (RESETBMCU), watchdog input (WDI), and processor-managed modes (STANDBY, PWRON, ONKEY). All buck converters feature internal soft-start, peak efficiency >90%, and quiescent current as low as 1.0 µA in ULP mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input voltage range | 4.1 V to 6.0 V (operational), with transient withstand up to +22 V - enables robust USB/adapter input without external surge protection |
| Buck converters | SW1 & SW2: 1.0 A, 0.6–1.3875 V (DVS), 12.5 mV steps; SW3: 1.0 A, 1.8–3.3 V (100 mV steps) - matches i.MX 6UL core, GPU, and I/O rail requirements |
| LDO outputs | LDO1/LDO3: 300 mA, 0.75–1.5 V or 1.8–3.3 V; LDO2: 400 mA, 1.8–3.3 V; LDO2P7: 2.7 V/5.0 mA always-on - powers USB PHY, sensors, and real-time logic |
| VREFDDR & VSNVS | VREFDDR: 0.5–0.9 V/10 mA (DDR3L-compatible reference); VSNVS: 3.0 V/2.0 mA RTC supply with coin-cell charging - ensures memory interface stability and persistent timekeeping |

| Package | 40-pin QFN, 5.0 mm × 5.0 mm with exposed pad - supports high thermal dissipation (RΘJA = 17.8 °C/W on 8-layer board) |
| I²C interface | Standard-mode (100 kHz) and fast-mode (400 kHz) compatible - enables full OTP configuration, voltage monitoring, and mode control via host processor |
Pinout & Package
MC32PF1510A3EPR2 is housed in a 40-pin QFN (5.0 mm × 5.0 mm, 0.5 mm pitch) with exposed thermal pad (EPAD, Pin 41), supporting industrial-grade thermal performance (RΘJB = 8.8 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW1IN (26), SW2IN (17), SW3IN (14) | Buck input supply nodes | Accept VSYS (2.5–4.5 V); require local 0.1 µF + 4.7 µF bypassing - critical for switching noise suppression and loop stability |

This includes fixed voltage settings for SW1 (1.0 V core), SW2 (1.1 V GPU), SW3 (3.3 V I/O), VREFDDR (0.75 V), and optimized startup timing - no field reprogramming is supported.
Does MC32PF1510A3EPR2 support dynamic voltage scaling (DVS)?
Yes, MC32PF1510A3EPR2 supports DVS on SW1 and SW2 buck converters, enabling real-time voltage adjustment in 12.5 mV steps between 0.6 V and 1.3875 V. This feature is enabled by default in its OTP configuration and controlled via I²C register writes from the i.MX 6UL host processor.
What is the maximum input voltage the MC32PF1510A3EPR2 can withstand?
The MC32PF1510A3EPR2 VIN pin withstands up to +22 V DC and transient inputs without damage or latch-up. Its operational input range remains 4.1 V to 6.0 V, but the 22 V rating eliminates need for external TVS protection in USB-powered or adapter-fed designs.
How does MC32PF1510A3EPR2 handle DDR3L memory reference voltage?
MC32PF1510A3EPR2 integrates a dedicated VREFDDR regulator delivering 0.5–0.9 V at 10 mA with ±2% accuracy - fully compliant with JEDEC DDR3L specifications. The output is internally derived from VINREFDDR/2 and requires only a 1.0 µF ceramic capacitor on VINREFDDR and VREFDDR pins.
Is MC32PF1510A3EPR2 pin-compatible with other PF1510 variants?
Yes, all PF1510 variants - including MC32PF1510A0EP through MC34PF1510A7EP - share identical 40-pin QFN packaging and pinout. Differences exist only in OTP programming, temperature grade (consumer vs. industrial), and part-number suffixes (e.g., "MC32" vs. "MC34"), not physical layout or signal mapping.
