Expanding the Controller Continuum - Introducing the MCF5445x Family

Page Contents:   [ Featured Products | Datasheets | Application Notes | Buy Now ]

The MCF5445x products are 32-bit microprocessors based on the V4m ColdFire microarchitecture featuring an enhanced multiplyaccumulate unit (eMAC), hardware divide and a memory management unit (MMU) allowing designers to run protected mode OS, such as Linux OS as well as other third party RTOSs.

In addition, the MCF5445x family features 32Kbytes of internal SRAM and 16Kbytes of both I-Cache and D-Cache and a DDR2/DDR memory controller that allows the use of DDR1, DDR2 and Mobile DDR memory. The MCF5445x also contains four 32-bit timers with DMA request capability, a 16-channel DMA controller, an I²C™ module, 3 UARTs, a DMA SPI, a hardware encryption module, an SSI module, a serial boot facility and an ATAPI hard drive controller.
