32-bit Microprocessor with USB On-The-Go, Ethernet, PCI, DDR2/DDR controller and Encryption

MCF5445X

The MCF5445x family of 32-bit microprocessors feature a rich set of connectivity peripherals including Ethernet, USB on-the-go (USB OTG) and peripheral component interconnect (PCI).

Developed for power-conscious designers, the MCF5445x family is ideal for consumer and embedded control designs that need high-performance and connectivity.

These highly integrated microprocessors open the door to expanding application capabilities while driving down total system cost and power requirements.

* NOTE: The SDRAM controller is capable of running at lower frequencies than some memory types support. When selecting a memory device for use with this controller, you should take into account the clock requirements for the memory along with the supported frequencies for the SDRAM controller and the resulting system frequency (SDCLK = fsys/2).
