Product details
Overview
MC32PF1510A2EPR2 from NXP Semiconductors is a preprogrammed power management IC (PMIC) optimized for i.MX 7ULP processors with LPDDR3 memory in low-power IoT and wearable systems. It integrates three 1.0 A buck converters (SW1–SW3), three LDOs (LDO1–LDO3), VSNVS (3.0 V RTC supply), VREFDDR (0.5–0.9 V DDR reference), USB_PHY LDO, and OTP-configurable power sequencing.
For engineers reviewing the MC32PF1510A2EPR2 datasheet, MC32PF1510A2EPR2 pinout, MC32PF1510A2EPR2 application, or MC32PF1510A2EPR2 equivalent, this page delivers verified electrical specs, I²C-programmable DVS on SW1/SW2, industrial-grade −40 °C to 105 °C operation, and QFN40 package layout guidance for i.MX 7ULP-based designs.
Technical Context
The MC32PF1510A2EPR2 implements a multi-rail PMIC architecture with dedicated regulators for processor core (SW1), SoC I/O (SW2), and peripheral/DDR termination (SW3), plus always-on LDO2P7 (2.7 V) and VSNVS (3.0 V). Its OTP memory stores i.MX 7ULP–LPDDR3–specific startup/shutdown sequences, voltage setpoints, and timing parameters.
It supports dynamic voltage scaling on SW1 and SW2 via I²C commands, operates in forced PWM or adaptive variable-frequency modes, and features ultra-low quiescent current (1.0 µA in ULP mode) with peak efficiency >90% at mid-load. Input withstand capability up to +22 V DC ensures robustness against transient surges on VIN.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.1 V to 6.0 V on VIN; withstands up to +22 V DC transients - enables direct USB/adapter input without external surge protection |
| Buck Converters | SW1/SW2: 0.6–1.3875 V (12.5 mV steps) or 1.1–3.3 V (variable); SW3: 1.8–3.3 V (100 mV steps) - covers i.MX 7ULP core, I/O, and LPDDR3 VDDQ/VTT rails |

Pinout & Package
MC32PF1510A2EPR2 uses a 40-pin QFN (5.0 mm × 5.0 mm) with exposed thermal pad (EPAD), designed for high-density portable applications requiring thermal performance and minimal footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Main IC supply input | Accepts 5.0 V adapter/USB input; bypassed with 2.2 µF capacitor - primary power entry point for front-end LDO |
| VSYS | Main system rail output | Regulated 3.7 V output from front-end LDO; powers all internal regulators - serves as common input for SW1/SW2/SW3 and LDOs |
| SW1FB / SW2FB / SW3FB | Voltage feedback inputs | Connect directly to respective output rails near load - enables precise closed-loop regulation and DVS tracking |
| VLDO1 / VLDO2 / VLDO3 | LDO output terminals | Each requires local 4.7–10 µF ceramic bypass - delivers stable low-noise bias for analog/RF/peripheral ICs |
| VREFDDR / VSNVS / USBPHY | Dedicated reference/RTC/PHY supplies | VREFDDR needs 1.0 µF bypass; VSNVS requires 0.47 µF; USBPHY needs 1.0 µF - ensures DDR timing integrity and USB PHY compliance |
| SCL / SDA / INTB / RESETBMCU | I²C interface and control signals | Pull-up to VDDIO (1.7–3.6 V) required; INTB/RESETBMCU are open-drain - enables bidirectional communication and system-level fault signaling |

FAQ
What is the operating temperature range for MC32PF1510A2EPR2?
The MC32PF1510A2EPR2 is specified for −40 °C to 85 °C ambient operation, qualifying it for consumer and commercial applications including wearables and home hubs. Its junction temperature limit is 125 °C, and thermal design must maintain RΘJA ≤ 20.6 °C/W on six-layer boards to stay within safe limits under full load.
Does MC32PF1510A2EPR2 support dynamic voltage scaling?
Yes, MC32PF1510A2EPR2 supports dynamic voltage scaling on SW1 and SW2 buck converters via I²C commands. This allows real-time adjustment of output voltages in 12.5 mV steps (0.6–1.3875 V range) to match i.MX 7ULP core frequency changes, reducing dynamic power consumption during low-activity periods.
What is the purpose of the VREFDDR output on MC32PF1510A2EPR2?
The VREFDDR output on MC32PF1510A2EPR2 provides a precision 0.5–0.9 V reference voltage for LPDDR3 memory interfaces, sourced from VINREFDDR/2. It delivers up to 10 mA with tight regulation (±2%) and requires a 1.0 µF ceramic bypass capacitor to ensure signal integrity and timing margin compliance in high-speed DDR links.
How is the MC32PF1510A2EPR2 programmed for i.MX 7ULP with LPDDR3?
The MC32PF1510A2EPR2 is factory-programmed with OTP configuration code "2", which defines i.MX 7ULP–LPDDR3–specific power-up sequencing, voltage setpoints (e.g., SW1 = 0.8 V core, SW2 = 1.1 V I/O), timing delays, and DVS enablement - eliminating need for external configuration during board bring-up.
What are the key differences between MC32PF1510A2EPR2 and MC34PF1510A2EPR2?
MC32PF1510A2EPR2 and MC34PF1510A2EPR2 share identical functionality, pinout, and OTP programming (code "2"), but differ in temperature rating: MC32PF1510A2EPR2 is rated −40 °C to 85 °C (consumer grade), while MC34PF1510A2EPR2 extends to −40 °C to 105 °C (industrial grade), making the latter suitable for harsher environments like factory floors or outdoor gateways.
