Product details
Overview
MC32PF4210A2ES 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), coin cell charger, and DDR reference (VREFDDR). It delivers precise power sequencing, dynamic voltage scaling, and OTP-configurable startup for OTT STBs and sound bars.
For engineers reviewing the MC32PF4210A2ES datasheet, MC32PF4210A2ES pinout, MC32PF4210A2ES application, or MC32PF4210A2ES equivalent, this page provides verified technical context, validated pin functions, confirmed thermal protection thresholds (110–130 °C), I²C-programmable rail voltages (e.g., VGEN2: 0.8–1.55 V/250 mA), and real-world use cases with i.MX 8M processors.
Technical Context
The MC32PF4210A2ES implements a fully configurable multi-rail architecture with independent control of up to six buck regulators-SW1A/B/C (configurable as 4.5 A single-phase or 2.5 A + 2.0 A dual-phase), SW2 (2.5 A, 0.4–3.3 V), SW3A/B (3.0 A combined or 1.5 A ×2), and SW4 (1.0 A, 0.4–3.3 V with DDR termination tracking mode). All buck stages support PWM, PFM, and APS modes, programmable soft-start, and OCP with fault interrupt.
Its control logic integrates OTP memory for nonvolatile startup sequence configuration, I²C interface (SDA/SCL, 3.6 V tolerant), and dedicated processor interface signals including open-drain INTB, SDWNB, RESETBMCU, and STANDBY. Thermal protection includes four programmable thresholds (THERM110I to THERM130I) with 2–4 °C hysteresis and 130–150 °C shutdown activation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | VIN = 2.8 V to 4.5 V - supports standard Li-ion or USB-powered A/V systems without external pre-regulation |
| Buck Regulator Count | Up to 6 independent outputs - enables full power delivery to i.MX 8M cores, LPDDR4, GPU, and peripherals from one IC |
| VGEN2 Output | 0.8 V to 1.55 V / 250 mA - supplies high-current digital I/O rails with tight regulation for HDMI PHY or MIPI interfaces |
| SWBST Boost Output | 5.0 V to 5.15 V / 600 mA - powers USB OTG host functionality directly, eliminating need for discrete boost IC |
| VREFDDR Accuracy | 0.6 V to 0.9 V / 10 mA - provides stable DDR4/LPDDR4 reference with tracking capability for VTT termination |
| Thermal Shutdown Threshold | 130 °C to 150 °C - hardware-protected fail-safe cutoff prevents die damage during sustained overload or poor PCB thermal design |
| OTP Memory | One-time programmable configuration storage - enables factory-customized power-up sequences without runtime I²C initialization |
Pinout & Package
MC32PF4210A2ES uses a 56-pin QFN package (8 mm × 8 mm, 0.5 mm pitch, wettable flank), thermally enhanced with exposed pad (EP) tied to GNDREF for efficient heat dissipation in compact A/V enclosures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW1ALX / SW1BLX / SW1CLX | Buck switch node outputs | High-frequency switching nodes for SW1A/B/C regulators - require low-inductance layout and ceramic output capacitors near each LX pin |
| VGEN2 / VGEN4 / VGEN6 | LDO outputs | Stable analog/digital supply rails (e.g., VGEN2 = 250 mA @ 0.8–1.55 V) - bypassed with 4.7 µF ceramic caps per datasheet layout guidance |
| INTB / SDWNB / RESETBMCU | Open-drain status outputs | Active-low interrupt, shutdown warning, and processor reset signals - require external pull-ups to VSNVS or VDDIO (≤3.6 V) |
| SCL / SDA / VDDIO | I²C interface | Standard two-wire bus (3.6 V tolerant) with dedicated 3.6 V supply (VDDIO) - enables full register-level configuration and fault monitoring |
| VIN / VIN1 / VIN2 / VIN3 | Main and auxiliary inputs | Dedicated input pins for buck regulators - each requires local 4.7 µF + 0.1 µF decoupling to suppress high di/dt noise |
| EP | Exposed thermal pad | GND-connected thermal interface - must be soldered to inner/outer ground planes via ≥6 vias for RΘJB ≤ 10 °C/W performance |
Key Features
| Feature | Design Value |
|---|---|
| Configurable Buck Architecture | SW1 and SW3 support single/dual-phase or independent operation - allows trade-off between current capacity (e.g., 4.5 A SW1A/B) and rail count (e.g., 1.5 A ×2 SW3A/SW3B) |
| DDR Termination Tracking | SW4 dynamically tracks 50 % of SW3A output - eliminates external resistor networks for LPDDR4 VTT biasing |
| Low-Power Modes | Standby current ≤ 550 µA (−40 °C to 105 °C) - sustains SNVS domain and critical logic while minimizing system idle power |
| Coin Cell Support | LICELL pin accepts 1.8–3.3 V coin cells with integrated charging circuit - maintains RTC and secure state during main power loss |
| Thermal Fault Interrupts | Four independent THERMxxxI interrupts (110/120/125/130 °C) - enable firmware-driven thermal throttling before hardware shutdown |

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 grade (−40 °C to 105 °C); identical electrical specs and pinout | Required for A/V receivers deployed in uncontrolled environments (e.g., attic-mounted units) | Select MC34PF4210A2ES when ambient operating temperature exceeds 85 °C or extended reliability qualification is mandated. |
| PF8100A1ES | 8-channel PMIC; lacks coin cell charger, DDR tracking, and VREFDDR; supports i.MX 8M but with reduced rail count | Suitable for cost-sensitive wireless audio where only core, memory, and I/O rails are needed | Choose PF8100A1ES only if system omits RTC backup, DDR termination, and HDMI PHY - not drop-in compatible due to missing VREFDDR and LICELL pins. |
Compared with MC32PF4210A2ES, MC34PF4210A2ES offers identical functionality with extended thermal range, while PF8100A1ES reduces channel count and removes critical A/V-specific features - making MC32PF4210A2ES the sole fit for full-featured i.MX 8M audio/video designs requiring DDR reference and coin cell support.

FAQ
What is the operating temperature range for MC32PF4210A2ES?
MC32PF4210A2ES is rated for 0 °C to 85 °C ambient operation, targeting consumer audio/video equipment such as OTT STBs and sound bars. Its thermal protection activates at 130–150 °C junction temperature, and it achieves RΘJA = 15 °C/W on an eight-layer board - enabling reliable operation without forced airflow in typical enclosures.
Does MC32PF4210A2ES support DDR4 memory termination?
Yes, MC32PF4210A2ES supports DDR4/LPDDR4 termination via its dedicated VREFDDR output (0.6–0.9 V, 10 mA) and SW4 tracking mode, which dynamically sets SW4 output to 50 % of SW3A voltage. This eliminates external resistor dividers and ensures accurate VTT biasing required for high-speed memory interfaces in i.MX 8M designs.
How is the startup sequence configured on MC32PF4210A2ES?
The MC32PF4210A2ES startup sequence is stored in on-chip OTP memory and factory-programmed per the A2 configuration. It supports fully programmable voltage levels, timing delays, and enable/disable ordering across all 14 channels. Users can validate sequences via I²C "Try Before Buy" mode before final OTP programming - no external configuration EEPROM is needed.
Can MC32PF4210A2ES operate from a coin cell alone?
Yes, MC32PF4210A2ES supports coin cell-only operation through the LICELL pin (1.8–3.3 V), powering the VSNVS domain (1.0–3.0 V selectable) and maintaining RTC functionality when main VIN is absent. In this mode, quiescent current drops to 4.0–7.0 µA, and the integrated charger conditions the coin cell when VIN is restored.
What I²C voltage levels does MC32PF4210A2ES support?
MC32PF4210A2ES supports I²C communication with SDA and SCL pins rated to 3.6 V maximum, and requires a dedicated VDDIO supply (1.7–3.6 V) to set logic threshold levels. The interface operates at standard (100 kHz) and fast (400 kHz) modes, enabling full register read/write access for real-time rail monitoring, fault logging, and dynamic voltage scaling control.
