Product details
Overview
MC34PF3000A6EPR2 from NXP Semiconductors is a power management IC (PMIC) engineered for the i.MX 6UL application processor with LPDDR2 memory, delivering four buck regulators (SW1A: 1.0 A, SW1B: 1.75 A, SW2: 1.25 A, SW3: 1.5 A), six LDOs including VCC_SD and V33, and integrated DDR reference (VREFDDR). It supports dynamic voltage scaling, I²C programmability, and coin-cell backup for RTC retention in portable industrial edge devices.
For engineers reviewing the MC34PF3000A6EPR2 datasheet, MC34PF3000A6EPR2 pinout, MC34PF3000A6EPR2 application, or MC34PF3000A6EPR2 equivalent, this page provides verified regulator configurations, OTP-programmed startup sequence for i.MX 6UL+LPDDR2, thermal-aware QFN-48 wettable flank package layout guidance, and validated alternative PMICs for i.MX 6-series migration paths.
Technical Context
The MC34PF3000A6EPR2 implements a multi-rail power architecture with configurable buck topology: SW1A and SW1B operate independently (1.0 A / 1.75 A) or combined (2.75 A), while SW2 and SW3 support dynamic voltage scaling across core, SOC, and DDR domains. Its OTP memory stores startup timing, voltage setpoints, and I²C address (0x08–0x0F), eliminating external configuration components.
Control logic integrates direct hardware interfaces-PWRON (edge/level configurable), STANDBY (active-high/low selectable), RESETBMCU (fault-aware reset), and SD_VSEL (dual-voltage SD card rail selection)-alongside I²C for runtime reconfiguration. The VSNVS 3.0 V always-on rail and VREFDDR (0.5 × SW3_OUT) ensure reliable i.MX 6UL system boot and DDR3L/LPDDR2 memory reference stability.

Pinout & Package
MC34PF3000A6EPR2 uses the 48-pin QFN (98ASA00933D) with wettable flank and 0.5 mm pitch. The exposed thermal pad (EP) must be soldered to internal/external ground planes via multiple vias for thermal integrity and EMI control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 INTB | Open-drain fault interrupt | Asserts low on overcurrent, undervoltage, or thermal fault; requires external pull-up to VDDIO |
| 2 SD_VSEL | Digital input for VCC_SD voltage selection | High = 1.8–1.85 V (SD card I/O), Low = 2.85–3.3 V; referenced to VDDIO supply |
| 3 RESETBMCU | Open-drain processor reset output | Deasserts 2 ms after final regulator enable; configurable for fault-triggered assertion |
| 4 STANDBY | Mode control input | Active-high or active-low entry into Standby; requires coin cell if VIN ≤ 2.85 V |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC33PF3000A6ES | Same silicon, −40 °C to +105 °C automotive grade; identical OTP programming and pinout | Qualified to AEC-Q100 Grade 2; required for automotive infotainment or ADAS companion modules | Select when functional safety (ISO 26262) or extended temperature validation is mandated |
| MC34PF3000A7EPR2 | OTP pre-programmed for i.MX 6UL + DDR3L (not LPDDR2); SW3 voltage range optimized for DDR3L VDDQ | Supports DDR3L memory instead of LPDDR2; different VREFDDR tracking ratio and startup timing | Choose only when migrating from LPDDR2 to DDR3L memory; not drop-in compatible due to OTP mismatch |

FAQ
What is the OTP programming configuration for MC34PF3000A6EPR2?
The MC34PF3000A6EPR2 is factory-programmed with OTP settings for i.MX 6UL + LPDDR2 operation: SW1B supplies VDD_ARM (0.7–1.475 V), SW3 generates DDR VDDQ (0.9–1.65 V), VREFDDR tracks SW3 at 0.5×, and startup sequence aligns with i.MX 6UL boot requirements. These values are fixed and cannot be modified post-manufacture.
Does MC34PF3000A6EPR2 support both DDR3L and LPDDR2 memory interfaces?
MC34PF3000A6EPR2 is specifically configured for LPDDR2 memory: its SW3 output range (0.9–1.65 V) and VREFDDR tracking ratio (0.5 × SW3) match LPDDR2 VDDQ and VREF specifications. It does not support DDR3L, which requires different voltage ranges and is implemented in MC34PF3000A7EPR2.
How is the VCC_SD regulator voltage selected on MC34PF3000A6EPR2?
MC34PF3000A6EPR2 uses the SD_VSEL pin (Pin 2) to select VCC_SD output: logic high sets 1.8–1.85 V for high-speed SD card I/O, while logic low selects 2.85–3.3 V for legacy SDIO peripherals. The buffer is powered by VDDIO, defaulting to high if VDDIO is absent-ensuring safe fallback behavior.
Can MC34PF3000A6EPR2 operate with a 5 V input supply?
Yes-MC34PF3000A6EPR2 accepts 3.7–5.5 V via the VPWR pin when used with an external PFET front-end LDO. This configuration limits internal regulator input to ≤4.5 V, enabling safe operation from 5 V sources. Direct 5 V connection to VIN is not permitted and may damage the device.
What is the role of the LICELL pin on MC34PF3000A6EPR2?
The LICELL pin (Pin 36) on MC34PF3000A6EPR2 provides bidirectional coin-cell interface: it charges a backup battery during main power operation and supplies the VSNVS 3.0 V always-on rail during power loss. This preserves RTC time, secure keys, and SNVS domain state for >10 years with typical CR2032 cells.
