Freescale i.MX53 Applications Processor

The Freescale i.MX53 applications processor is central component of the Opal CPU Module. It incorporates a Cortex-A8 core running at 800MHz

(optionally up to 1.2GHz), along with memory controllers and peripherals which enable connections to a wide range of devices.
Read the

i.MX53 Features chapter for more details.

Memory

The Opal CPU Module includes:

• 512Mbytes or 1Gbyte DDR3 memory.
• 512Mbytes - 2Gbytes NAND Flash (optional)

If NAND flash is not fitted, Opal can boot from an SD Card on the base-board.

10/100 Ethernet

The i.MX53 includes a 10/100 Ethernet MAC, and the Opal module expands on this functionality by adding a Micrel KSZ8051 PHY. For detailed information on the MAC, refer to the Freescale documentation.
The signals present on the Opal interface are:

Power Management

Opal includes a Dialog Semiconductor DA9053 Power Management IC. This provides power supplies for the i.MX53 and a number of extra features including battery management,

touch-screen and analog inputs.

This page has more details on the capabilities of this part.

Debug

Programming and debugging software on the Opal CPU module can be done in a number of ways depending on tools available. These include:

• JTAG. Standard JTAG signals available are TMS, TCK, TDI, TDO and TRST. This requires a JTAG debugger or programmer and appropriate software.
• USB and serial boot mode.
• Ethernet
