Product details
Overview
MC34PF3000A5EPR2 from NXP Semiconductors is a power management IC (PMIC) engineered for i.MX 6SL application processors 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, VREFDDR reference, and coin-cell backup. It supports dynamic voltage scaling, programmable startup sequencing via OTP, and I²C configuration - enabling full-system power control in compact embedded designs.
For engineers reviewing the MC34PF3000A5EPR2 datasheet, MC34PF3000A5EPR2 pinout, MC34PF3000A5EPR2 application, or MC34PF3000A5EPR2 equivalent, key selection considerations include its pre-programmed OTP configuration for i.MX 6SL + LPDDR2, 48-pin 7.0 mm × 7.0 mm QFN wettable flank package, input voltage support up to 5.5 V, and integrated DDR memory reference generation.
Technical Context
The MC34PF3000A5EPR2 implements a multi-rail architecture with configurable buck regulator pairing (SW1A/SW1B as independent or combined 2.75 A), programmable soft-start ramp rates (25 mV/2–4 μs), and three operating modes per buck (PWM, PFM, APS). Its OTP memory stores startup sequence timing, voltage setpoints, and I²C address (0x08–0x0F), eliminating external configuration components.
Control logic integrates dedicated interface signals: PWRON (edge- or level-sensitive with hardware debounce), STANDBY (active-high/low configurable), RESETBMCU (fault-aware or timer-based reset assertion), and SD_VSEL (dual-range VCC_SD selection). The VSNVS rail provides always-on 3.0 V at 1.0 mA for SNVS/SRTC domains, powered optionally from VIN or coin cell.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC33PF3000A5ES | Automotive-grade variant (–40 °C to +105 °C), identical OTP configuration for i.MX 6SL + LPDDR2, same pinout and electrical specs | Qualified to AEC-Q100 Grade 3; required for automotive infotainment or telematics modules | Select MC33PF3000A5ES only when automotive qualification is mandatory; otherwise MC34PF3000A5EPR2 is optimal for industrial use. |

FAQ
What is the OTP programming configuration of MC34PF3000A5EPR2?
The MC34PF3000A5EPR2 is factory-programmed with OTP settings optimized for the i.MX 6SL application processor paired with LPDDR2 memory. This includes startup sequence timing, core voltage setpoints (e.g., SW1A at 1.1 V), VCC_SD range selection (1.8 V), and DDR reference derivation from SW3. No field reprogramming is possible after shipment.
Does MC34PF3000A5EPR2 support both VIN and VPWR input configurations?
Yes, MC34PF3000A5EPR2 supports dual-input operation: VIN (2.8–4.5 V) for standard systems, and VPWR (3.7–5.5 V) when used with an external PFET front-end LDO. The VPWR path enables compatibility with higher-voltage batteries or adapters while keeping internal regulator inputs within safe limits.
How does the VREFDDR output relate to SW3 on MC34PF3000A5EPR2?
On MC34PF3000A5EPR2, VREFDDR is generated as exactly 0.5 × the SW3 output voltage - for example, if SW3 is set to 1.35 V for LPDDR2 core, VREFDDR automatically becomes 0.675 V. This ratio is fixed and internally trimmed, eliminating external resistive dividers and improving DDR timing accuracy.
Can MC34PF3000A5EPR2 operate without a coin cell connected?
MC34PF3000A5EPR2 can operate without a coin cell when VIN ≥ 2.85 V, but VSNVS will be sourced from VIN. However, Standby mode entry/exit reliability degrades below 2.85 V without coin-cell backup. For robust RTC retention and low-power state transitions, a coin cell is strongly recommended.
What is the function of the SD_VSEL pin on MC34PF3000A5EPR2?
The SD_VSEL pin on MC34PF3000A5EPR2 selects the output voltage range of the VCC_SD regulator: logic HIGH configures 1.8 V / 1.85 V for LPDDR2 I/O, while logic LOW selects 2.85–3.3 V for legacy SD card interfaces. This enables single-hardware support for multiple memory types without redesign.
