The MYD-IMX28X Development Board designed by MYIR is a cost-effective and power-efficient ARM Evaluation Kit (EVK) for NXP i.MX28 family of multimedia applications processors which has an ARM926EJ-S Core, with speed up to 454 MHz. The board can support running Linux operating systems, which allows developers to use it as an i.MX28 reference platform to quickly start their own design. The board takes full features of the i.MX28 ARM processor and has exposed a comprehensive set of peripherals and connectivity options to make the board suitable for smart gateways, human-machine interfaces (HMIs), handheld devices, scanners, portable medical, experimental education and more other industrial applications.

The
MYD-IMX28X Development Board is using the MYC-IMX28X CPU module as the heart of the system which is an ARM9-based system-on-module (SOM) integrated with the i.MX28 processor, 128MB DDR2 SDRAM, 256MB Nand Flash and Ethernet PHY. It is connected to the base board through two 1.27mm pitch 80-pin connectors. The base board has extended many peripherals and interfaces through headers and connectors, featuring 1 x RS232, 1 x Debug, 2 x USB ports, up to 2 x Ethernet, 2 x CAN, 1 x RS485, TF, Audio, LCD, JTAG, etc.




MYIR offers the board with Freescale i.MX283 or i.MX287 ARM9 CPU by default; user can integrate a different MYC-IMX28X CPU module on the same base board, thus making two variants of i.MX28 evaluation boards.

MYD-IMX283 Development Board – with MYC-IMX283 CPU Module for Freescale i.MX283

MYD-IMX287 Development Board – with MYC-IMX287 CPU Module for Freescale i.MX287


The MYD-IMX283 and MYD-IMX287 boards only have a few differences as described in below table:

MYS-6ULX Single Board Computer (based on i.MX 6UL/6ULL)

MYD-Y6ULX Development Board (MYC-Y6ULX CPU Module as core board)


Hardware Specification

The i.MX28 is a low-power, high-performance applications processor optimized for the general embedded industrial and consumer markets. The core of the i.MX28 is Freescale's fast, power-efficient implementation of the ARM926EJ-S™ core, with speeds of up to 454 MHz.

The device is suitable for a wide range of applications, including the following:

  • Human-machine interface (HMI) panels: industrial, home
  • Industrial drive, PLC, I/O control display, factory robotics display, graphical remote controls
  • Handheld scanners and printers
  • Patient-monitoring, portable medical devices
  • Smart energy meters, energy gateways
  • Media phones, media gateways

The integrated power management unit (PMU) on the i.MX28 is composed of a triple output DC-DC switching converter and multiple linear regulators. These provide power sequencing for the device and its I/O peripherals such as memories and SD cards, as well as provide battery charging capability for Li-Ion batteries.

The i.MX28 processor includes an additional 128-Kbyte on-chip SRAM to make the device ideal for eliminating external RAM in applications with small footprint RTOS.

The i.MX28 supports connections to various types of external memories, such as mobile DDR, DDR2 and LV-DDR2, SLC and MLC NAND Flash.

The i.MX28 can be connected to a variety of external devices such as high-speed USB2.0 OTG, CAN, 10/100 Ethernet, and SD/SDIO/MMC.
