NXP i.MX28 EVK Hardware User's Guide
Hardware guide for the NXP i.MX28 Evaluation Kit, detailing the i.MX28 processor, memory, connectivity, and peripheral interfaces for embedded system development.
Overview
The i.MX28 EVK Hardware User's Guide provides a comprehensive technical overview of the evaluation board based on the NXP i.MX28 processor. It details the hardware architecture, including the ARM926EJ-S core, DDR2 SDRAM (Elpida EDE1116AEBG), and NAND Flash memory systems. The document covers the implementation of key peripherals such as dual 10/100 Ethernet (Microchip LAN8720), USB 2.0 OTG and Host (Richtek RT9706), and CAN bus (Infineon TLE6251DS). Additionally, it describes the audio subsystem using the SGTL5000 codec, UART communications via Maxim MAX3222, and power monitoring utilizing the Linear Technology LTC2487. It includes block diagrams for boot mode selection, JTAG, MMC/SD interfaces, and I/O MUX configurations.
Use Cases
- Evaluating i.MX28 processor performance and peripheral features
