NXP Semiconductors MMPF0100F4AEP

Overview

MMPF0100F4AEP from NXP Semiconductors is a 14-channel configurable power management IC (PMIC) designed for i.MX 6-based embedded platforms. It integrates six buck converters (including SW1A/B/C, SW2, SW3A/B, SW4), six LDOs (VGEN1–VGEN6), coin-cell charger, RTC supply, DDR termination reference (VREFDDR), and I²C programmable control logic. It delivers up to 2.5 A per high-current buck channel and supports full power sequencing for application processors and memory subsystems in industrial automation and medical monitoring systems.

For engineers reviewing the MMPF0100F4AEP datasheet, MMPF0100F4AEP pinout, MMPF0100F4AEP application, or MMPF0100F4AEP equivalent, key selection considerations include its OTP-programmable configuration for i.MX 6Solo/SoloLite platforms, 56-pin QFN 8×8 mm E-type package with exposed thermal pad, -40 °C to +85 °C operating range, and integrated VSNVS LDO/switch for always-on domain support.

Technical Context

The MMPF0100F4AEP implements a hierarchical power tree with independent state machine control for each regulator group, enabling precise startup/shutdown sequencing across core, memory, and peripheral rails. Its architecture includes dual-phase capability on SW1A/B, DDR tracking mode via VREFDDR, and programmable DVS control synchronized to processor requests over I²C.

Control logic integrates 32 kHz and 16 MHz clock sources, OTP-configurable POR behavior, and thermal interrupt monitoring (THERM110I–THERM130I). The device uses internal bandgap references (VCOREREF, VCOREDIG) and supports external biasing of VHALF for DDR voltage tracking accuracy within ±1%.

FAQ

What is the primary target platform for the MMPF0100F4AEP?

The MMPF0100F4AEP is specifically configured for i.MX 6Solo and i.MX 6SoloLite application processors. Its OTP programming defines voltage setpoints, power-up sequencing order, and timing delays aligned with the boot requirements of these SoCs-including core (VCORE), DDR memory (VREFDDR), and peripheral rail dependencies. This ensures deterministic initialization without external configuration firmware.

Does the MMPF0100F4AEP support DDR3L memory termination?

Yes, the MMPF0100F4AEP supports DDR3L termination through its VREFDDR regulator, which delivers a precision 0.6–0.9 V output with ±1% accuracy. When paired with an externally supplied VHALF reference (VDDQ/2), it actively tracks DDR3L VDDQ variations to maintain compliant termination voltage-critical for signal integrity in high-speed memory interfaces.

Can the MMPF0100F4AEP operate without I²C configuration?

Yes, the MMPF0100F4AEP can operate autonomously using its one-time programmable (OTP) memory. All critical parameters-including regulator enable states, output voltages, sequencing delays, and fault responses-are stored in OTP and executed at power-on without host intervention. I²C is required only for runtime reconfiguration, diagnostics, or dynamic voltage scaling.

What thermal protection features does the MMPF0100F4AEP provide?

The MMPF0100F4AEP integrates four programmable thermal thresholds (110 °C, 120 °C, 125 °C, 130 °C) that generate distinct interrupt signals (THERM110I–THERM130I). These allow firmware to implement graduated responses-such as reducing CPU frequency or disabling non-critical rails-before initiating forced shutdown at 130 °C, protecting against permanent die damage.

How is the coin-cell backup function implemented in the MMPF0100F4AEP?

The MMPF0100F4AEP implements coin-cell backup via the LICELL pin, which connects directly to a CR1220 or similar 3 V cell. Internal circuitry automatically switches between main VIN supply and LICELL during brownout, charges the cell at 10 µA nominal rate, and powers the VSNVS rail to sustain RTC, tamper detection, and secure non-volatile storage-even when main power is absent.
