Description

Measuring only 62mm by 38mm, the MYC-IMX28X is a low-cost and high-performance ARM embedded controller board based on Freescale i.MX28 family applications processor with ARM926EJ-S core and speeds of up to 454MHz. It integrates 128MB DDR2 SDRAM, 256MB Nand Flash, 128KB SPI Flash as well as one Ethernet PHY on board and has two 1.27mm pitch 80-pin SMT connectors to allow all the I/O signals brought in and out from the CPU Module for further expansion.


The MYC-IMX28X CPU Module is a ready-to-run system-on-module (SoM) which can be embedded into your next design for volume production or prototype. It can also come with MYIR own designed base board along with Linux 2.6.35 software packages, document and other necessary cable accessories to enable rapid development based on this Freescale i.MX28 starter kit MYD-IMX28X.

MYIR offers the module 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.

MYC-IMX283 CPU Module for Freescale i.MX283

MYC-IMX287 CPU Module for Freescale i.MX287


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

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.
