Microprocessors for Linux applications

17 October 2007 DSP, Micros & Memory

Freescale has introduced a ColdFire microprocessor family designed to enable low-power, high-performance embedded systems running the Linux operating system (OS). Delivering 410 Dhrystone MIPS (DMIPS) core performance at approximately 380 mW, these latest ColdFire microprocessors are designed to be easy on the developer's system power budget, while enabling exceptional system-level performance. The MCF5445x family includes 12 advanced microprocessors that integrate a rich set of connectivity peripherals. The devices include an on-chip memory management unit to support protected memory operating systems such as the Linux OS, as well as other third-party realtime OSs. The MCF5445x family supports 10/100 Ethernet, USB on-the-go (OTG), advanced technology attachment (ATA) and peripheral component interconnect (PCI), enabling easy integration of PCI-based peripherals. The devices feature an on-chip DDR memory controller that supports DDR1, DDR2 and mobile DDR memory. The inclusion of a dual-role master/slave serial peripheral interface (SPI) allows other SPI devices to communicate with the MCF5445x as a master or slave.
