Product details
Overview
MC32PF4210A2ESR2 from NXP Semiconductors is a 14-channel programmable PMIC optimized for i.MX 8M-based audio/video systems, integrating six buck converters (including SW1A/B/C, SW2, SW3A/B, SW4), six LDOs (VGEN1–VGEN6), a 5.0 V boost regulator (SWBST), DDR termination reference (VREFDDR), and coin cell charger with RTC supply. It delivers up to 4.5 A on SW1A/B/C in combined mode and supports dynamic voltage scaling for processor core rails.
For engineers reviewing the MC32PF4210A2ESR2 datasheet, MC32PF4210A2ESR2 pinout, MC32PF4210A2ESR2 application, or MC32PF4210A2ESR2 equivalent, key selection criteria include OTP-configurable startup sequencing, I²C-controlled power state management (standby/sleep/off), thermal protection thresholds (110–130 °C), and compatibility with LPDDR4 memory interfaces via VREFDDR and VTT tracking.
Technical Context
The MC32PF4210A2ESR2 implements a multi-rail power architecture with configurable buck topology: SW1A/B/C supports single/dual-phase or independent operation (0.3–1.875 V, up to 4.5 A); SW3A/B offers 3.0 A in dual-phase or 1.5 A per rail; SW4 provides 1.0 A with DDR termination tracking capability. All buck regulators support PWM, PFM, and APS modes with programmable soft-start, current limit, and switching frequency.
Control logic integrates OTP memory for nonvolatile startup configuration, I²C register interface (SDA/SCL), and dedicated processor signaling (PWRON, STANDBY, RESETBMCU, SDWNB, INTB). The device includes thermal monitoring with four interrupt-enabled thresholds (THERM110I–THERM130I) and automatic shutdown at ≥140 °C, plus coin-cell-backed SNVS supply (VSNVS) with 1.0 mA industrial-rated output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | VIN = 2.8 V to 4.5 V - supports single-cell Li-ion or regulated 3.3 V/5 V system supplies |
| Buck Regulator Count | Up to 6 independent outputs - enables full-system power delivery for i.MX 8M SoC, memory, and peripherals |
| Max Buck Output Current | SW1A/B/C = 4.5 A combined - powers CPU cores with dynamic voltage scaling under load |
| Boost Output | SWBST = 5.0 V to 5.15 V, 600 mA - supplies USB OTG or external 5 V peripherals |
| VREFDDR Accuracy | 0.6 V to 0.9 V, ±1 % - ensures stable DDR4/LPDDR4 reference for memory termination |
| Quiescent Current (Standby) | 297 µA typical - maintains low-power state while keeping all rails enabled except boost |
| OTP Memory | One-time programmable - stores startup sequence, voltage levels, timing, and fault response behavior |
| Thermal Shutdown Threshold | 140 °C (typical) - failsafe protection with 8 ms debounce prevents false triggers during transient spikes |
Pinout & Package
MC32PF4210A2ESR2 uses a 56-pin QFN package (8 mm × 8 mm, 0.5 mm pitch, wettable flank), thermally enhanced with exposed pad (EP) tied to GND for dissipation. Pin functions are validated per NXP datasheet Rev. 2.0 (2018), including dedicated feedback (SW1FB, SW2FB), switch-node (SW1ALX, SW2LX), and I²C (SDA, SCL) terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INTB | Digital output | Open-drain fault interrupt - signals overcurrent, thermal, or startup failure to host processor |
| PWRON | Digital input | Edge- or level-sensitive power-on trigger - initiates OTP-defined startup sequence |
| RESETBMCU | Digital output | Configurable reset signal - deasserts after successful startup or asserts on persistent fault (>100 ms) |
| SW1ALX / SW1BLX / SW1CLX | Analog output | Switch-node connections for buck regulators - require external inductor and synchronous rectifier layout |
| VREFDDR | Analog output | DDR termination reference - must be routed with controlled impedance and low-noise decoupling |
| VSNVS | Analog output | Always-on supply for SNVS domain - selectable 1.0/1.1/1.2/1.3/1.5/1.8/3.0 V, 1.0 mA (industrial temp) |
| SDA / SCL | Digital I²C | Two-wire interface - operates at up to 400 kHz, open-drain with 3.6 V max rating |
| EP | GND | Exposed thermal pad - mandatory connection to internal/external ground planes via multiple vias |
Key Features
| Feature | Design Value |
|---|---|
| Configurable Buck Topology | SW1 and SW3 support single/dual-phase or independent operation - enables trade-off between current capacity and rail count |
| DDR Termination Tracking | SW4 tracks 50 % of SW3A output - eliminates need for external VTT regulator in LPDDR4 designs |
| OTP Startup Configuration | Nonvolatile storage of voltage levels, sequencing order, and timing delays - removes external configuration EEPROM |
| Thermal Protection | Four user-maskable interrupt thresholds (110/120/125/130 °C) + hard shutdown at 140 °C - enables graded system response before failure |
| Coin Cell Integration | LICELL input with integrated charger and VSNVS backup - sustains real-time clock and secure nonvolatile storage during main power loss |
| I²C Programmable States | Individual on/off/standby control per regulator - allows fine-grained power gating for audio DSP, camera ISP, or wireless subsystems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC34PF4210A2ES | Industrial temperature range (−40 °C to 105 °C) vs. consumer (0 °C to 85 °C); identical pinout, OTP structure, and electrical specs | Required for automotive infotainment or industrial AV receivers operating outside consumer ambient limits | Select MC34PF4210A2ES when extended temperature operation or higher thermal reliability is mandated. |
| PF8100A1ES | Higher integration: adds 3x additional LDOs, integrated fuel gauge, and enhanced thermal monitoring; different pinout and OTP mapping | Targets premium A/V receivers needing battery telemetry and more peripheral rails; not drop-in compatible | Choose PF8100A1ES only if additional LDOs, fuel gauging, or upgraded thermal diagnostics justify PCB redesign. |
Compared with MC32PF4210A2ESR2, MC34PF4210A2ES offers identical functionality with extended temperature qualification, while PF8100A1ES provides broader feature set at the cost of layout incompatibility - making the former a direct upgrade path and the latter a next-generation alternative requiring system-level revalidation.

FAQ
What is the operating temperature range for MC32PF4210A2ESR2?
The MC32PF4210A2ESR2 is rated for 0 °C to 85 °C ambient operation, qualifying it for consumer-grade audio/video equipment such as OTT streaming boxes and sound bars. This range aligns with its A2 programming variant designation and matches the thermal specifications defined in the NXP PF4210 datasheet Rev. 2.0. Exceeding 85 °C ambient may trigger thermal interrupts or shutdown depending on junction temperature rise.
Does MC32PF4210A2ESR2 support DDR4 memory termination?
Yes, MC32PF4210A2ESR2 supports DDR4/LPDDR4 termination through its dedicated VREFDDR output (0.6 V to 0.9 V, ±1 %) and SW4 buck regulator configured in VTT tracking mode, which delivers 50 % of SW3A's output voltage. This eliminates the need for an external VTT regulator in i.MX 8M-based designs using DDR memory interfaces.
How is the startup sequence configured on MC32PF4210A2ESR2?
The MC32PF4210A2ESR2 startup sequence is stored in on-chip one-time programmable (OTP) memory and is fixed at manufacturing for the A2 variant. Voltage levels, enable timing, and sequencing order are preconfigured to match i.MX 8M processor requirements. No runtime I²C reprogramming of the primary startup flow is possible - only runtime adjustment of individual regulator states post-boot.
Can MC32PF4210A2ESR2 operate without a coin cell battery?
Yes, MC32PF4210A2ESR2 can operate without a coin cell - VSNVS is powered from VIN by default. However, if VSNVS is programmed to 3.0 V and VIN drops below 2.85 V, a coin cell (connected to LICELL) becomes mandatory to maintain reliable standby/exit functionality. The internal coin cell charger remains inactive unless a valid cell is detected.
What I²C address does MC32PF4210A2ESR2 use?
The MC32PF4210A2ESR2 uses a fixed 7-bit I²C slave address of 0x48 (0x90 write, 0x91 read), as defined in the NXP PF4210 register map. Address pins are not provided - communication occurs exclusively via SDA and SCL pins with open-drain pull-ups to VDDIO (1.7–3.6 V). No address selection resistors or configuration bits exist.
