MC32PF3000A1EP Introduction

If you’re using an NXP, i.MX 7 or i.MX 6SL/SX/UL application processor, you’ll need a PMIC like the PF3000. The PF3000 can power various components, including application processors, memory, system peripherals, and coin-cell batteries. This gadget uses SMARTMOS technology.

General Description

NXP’s i.MX 7 multi-media application processors are designed to work best with the PF3000 power management integrated circuit (PMIC). Furthermore, it can supply a complete power solution for i.MX 6SL/SX/UL CPUs.

MC32PF3000A1EP Features

  • To supply energy to electronic devices, the MC32PF3000A1EP is a highly integrated power management IC with various options. The maximum output currents of the 1.75 A, 1.5 A, 1.25 A, and 1.0 A adjustable buck regulators are as follows. The regulators provide configurable modes that allow for greater efficiency at low loads, including Pulse Width Modulation (PWM), Pulse Frequency Modulation (PFM), and Auto PFM/Auto PWM (APS).
  • The device also features a PFM or auto mode 5.0 V, 600 mA boost regulator for higher input voltage applications. The MC32PF3000A1EP also features six general-purpose linear regulators with customizable settings for added flexibility.
  • A 2.8 V to 4.5 V and a 3.7 V to 5.5 V input voltage range make the device universally applicable. The device’s OTP (Time Programmable) memory for configuration enables the power management solution to be tailored to individual applications.
  • The I2C interface also allows the device’s start-up sequence and timing to be customized, as well as the output voltage, frequency, and soft start. If your project needs a reliable way to keep track of time, go no further than the MC32PF3000A1EP, which comes with an integrated coin cell charger and a constant power source for a Real-Time Clock.
  • With the MC32PF3000A1EP’s DDR (Double Data Rate) reference voltage, your DDR memory applications will always run smoothly and reliably. The device is usable in a wide temperature range, from -40 degrees Celsius to +125 degrees Celsius (working junction temperature range). All things considered, the MC32PF3000A1EP is an excellent power management solution that is adaptable to a wide variety of electrical gadgets.

Functional Description and Application Information

The PF3000 is a highly integrated power management IC with a low quiescent current. It contains four buck regulators, one boost regulator, one DDR voltage reference, and seven LDO regulators. The PF3000 supplies power to the entire system, including the application processor, memory, and peripherals. The input voltage range for the PF3000 is 2.7 V to 5.5 V. Because the output voltage, startup sequence, and other functions may all be written into the device’s internal one-time-programmable (OTP) memory, fewer additional parts are required.

Power Generation

The PF3000’s buck regulators deliver power to the processor cores and additional voltage domains, like I/O and memory. Dynamic voltage scaling is offered for the processor cores and accompanying electronics to enable controlled supply rail modifications. The SW1A and SW1B buck regulators can be used separately as regulators of 1.0 A and 1.75 A or together as a single 2.75 A regulator. The linear regulators of the PF3000 can be utilized as all-purpose regulators to power CPU rails and peripherals that require less power. High-speed SD card readers need dual voltage, supported by the VCC SD LDO regulator. Depending on how the system power path is set up, the switching regulators or the main input supply can be used to power the LDO regulators, which in turn power peripheral devices such as the audio, camera, Bluetooth, and Wireless LAN.

The inclusion of a particular VREFDDR voltage reference ensures proper reference voltage for DDR memories. For powering the SNVS/SRTC circuitry on the i.MX CPUs, the VSNVS block functions as an LDO or a bypass switch; it can be driven by VIN or a coin cell. To accommodate applications powered by main supplies higher than 4.5 V and up to 5.5 V, the PF3000 incorporates a front-end LDO regulator that uses an external pass FET to Set the regulators’ maximum input voltage to 4.5 V. The regulators can be powered directly from applications with input voltages lower than 4.5 V without a front-end LDO. A list of the voltage regulators in the PF3000 is displayed in PF3000.

Functional Description

● Control Logic and Interface Signals

The I2C interface allows for the complete programmability of the PF3000. Direct logic interfacing, which includes INTB, RESETBMCU, STANDBY, PWRON, and SD VSEL, allows for further communication.


The IC receives the input signal STANDBY. The part goes into standby mode when asserted and comes out of standby mode when it is de-asserted. With the STANDBYINV bit, STANDBY can be set to high or low. For the PMIC to reliably enter and exit the STANDBY mode when operating at VIN 2.85 V, a coin cell must be present to supply VSNVS.


RESETBMCU has two configurable modes of operation and is an active low output, open-drain OTP. When the last regulator in the startup sequence is activated, it will be de-asserted after 2.0 milliseconds. This signal is only active during a power down and can be used to indicate that all supplies are now on or to reset the CPU (POR).

The regulators are not monitored when the RESETBMCU signal is activated; instead, it uses an internal timer. When set to its fault mode, RESETBMCU will not be released until the start-up sequence is complete unless no errors occur. When a fault occurs and continues for more than 1.8 ms, RESETBMCU is asserted LOW. The PF3000 will be turned off if the problem persists for more than 100 milliseconds. If the problem persists, the above procedures are repeated, but the component can be restarted by sending the PWRON signal. To enter fault mode during OTP programming, set bit OTP PG EN of register OTP PWRGD EN to 1.


The INTB is an active low-output open-drain device. For each unmasked fault interrupt, this signal is asserted. As soon as the software writes a “1” to the fault interrupt bit, deasserting INTB follows. SD VSE


In conclusion, the NXP i.MX 7 and i.MX 6SL/SX/UL application processors are ideal candidates for the MC32PF3000A1EP power management integrated circuit because of their excellent performance and versatility. An entire system’s worth of memory, application processors, and peripherals may be powered by the PF3000 thanks to its efficient buck and linear regulators, boost regulator, and DDR voltage reference. The fact that the start-up sequence can be customized, the output voltage can be set, and it has a soft start means it can be used with various electrical gadgets. Powered by SMARTMOS technology, which guarantees dependable and efficient power management, the device can run in a wide temperature range (from -40 degrees Celsius to +125 degrees Celsius) and has a wide junction temperature operating range.
