ROHM Semiconductor, as of late declared that Embedded Artists is utilizing their highly incorporated PMIC, the BD71847AMWV alongside i.MX 8M Nano from NXP on the new iMX8M Nano uCOM board to convey a robust and practical answer for modern applications. This new uCOM board estimated to be around 45mm x 42mm in size, and featuring the i.MX 8M Nano processor with Quad-core ARM Cortex-A53 and Cortex-M7 running at up to 1.5GHz/750MHz.


The high performance 13,800 DMIPS board additionally integrates a 1 GByte DDR4 2400 MT/s; 16-bit databus; 8 GByte eMMC on-board Flash; MIPI-DSI graphical yield and MIPI-CSI camera input; USB2.0, Gigabit Ethernet, and different interfaces; as well as an optional Murata 1MW Wi-Fi/BT module supporting 802.11 a/b/g/n/ac and BT/BLE 5.0. With low power consumption, the iMX8M Nano uCOM board is ideal for long duty cycle, battery-fueled remote applications, and other induatrial as well as consumer applications.


  1. 6 Buck Regulators
  2. 2.0 MHz Switching Frequency.
    (BUCK1, BUCK2, BUCK5, BUCK7, and BUCK8).
  3. 1.5MHz Switching Frequency. (BUCK6)
  4. Target Efficiency: 83% to 95%.
  5. 6ch Linear Regulators (6 LDOs)
  6. Power Mux Switch
  7. 1.8V/3.3V Input: 500 mΩ(Max)
  8. 32.768 kHz Crystal Oscillator Driver
  9. Power Button Detector
  10. Protection and Monitoring: Soft Start, Power Rails Fault Detection, UVLO, OVP and TSD
  11. OTP Configurable Power Sequencing
  12. Interfaces:
    • I2C: 100 kHz/400 kHz, 1 MHz
  13. Power-on Reset Output: POR_B, RTC_RESET_B,

By incorporating the two gadgets in one iMX8M Nano uCOM board, Embedded Artists has pointed toward offering high adaptability, programming programmability, and OTP configurability which makes this ease, across the board power arrangement ideal for SoC, recollections, and regular framework peripherals. Moreover, its pinout is customized such that it facilitates PCB format as it takes out the requirement for remote sensing.

ROHM offers the BD71847AMWV  in i.MX 8M Mini and Nano designs using the same PCB or a custom PCB for i.MX Nano designs in a pin compatible solution.
