Freescale Unveils 12 High-Performance ColdFire(R) Microprocessors for Linux(R) Applications.Power-Efficient, Peripheral-Rich MCF5445x Family Delivers More Than 400 DMIPS DMIPS Dhrystone MIPS (Million Instructions Per Second) Core Performance at Less Than 400 mW AUSTIN, Texas -- Continuing to expand the range of price-performance options within its Controller Continuum, Freescale Semiconductor has introduced a ColdFire[R] microprocessor family designed to enable low-power, high-performance embedded systems running the Linux[R] operating system (OS). Delivering 410 Dhrystone MIPS (Million Instructions Per Second) The execution speed of a computer. For example, .5 MIPS is 500,000 instructions per second; 100 MIPS is a hundred million instructions per second. (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. Freescale's MCF5445x family includes 12 advanced microprocessors that integrate a rich set of connectivity peripherals. The MCF5445x devices include an on-chip memory management unit to support protected memory operating systems, such as the Linux OS. The MCF5445x family supports 10/100 Ethernet, USB USB in full Universal Serial Bus Type of serial bus that allows peripheral devices (disks, modems, printers, digitizers, data gloves, etc.) to be easily connected to a computer. On-The-Go (OTG (1) See USB OTG. (2) (The OBJECTive Technology Group, Ltd., Alexandria, VA) An organization that was devoted to distributed computing and object technology.

"Freescale has expanded its ColdFire MCU (1) (MicroController Unit) A computer on a single chip. See microcontroller. (2) (Multipoint Control Unit) A device that is used to moderate a videoconference of three or more end points (users at computers or groups of users portfolio by an impressive 25 percent with the launch of these 12 high-performance microprocessors, combined with the addition of 10 ColdFire MCUs for entry-level applications," said Tony Massimini, chief of technology at Semico Research Corporation. "The MCF5445x devices' high level of performance at less than 400 mW is impressive makes them compelling solutions for power-sensitive applications that require flexible connectivity options." The wide range of price, peripheral, power and performance options makes the MCF5445x family an ideal solution for consumer applications, such as network-attached storage and Ethernet gateways. The processor family also fits well in a broad array of embedded control applications, such as industrial control, embedded voice over IP (VoIP), factory automation, point-of-sale terminals, test and measurement equipment, and health care equipment. "The MCF5445x family hits the sweet spot in value, performance and integration for 32-bit microprocessors," said Mike McCourt, vice president and general manager of Freescale's Microcontroller Division. "Embedded system designers who previously thought this level of processing performance was unaffordable are now able to enhance their system designs by adding more performance and higher-speed connectivity." About the MCF5445x family The MCF5445x microprocessors are based on the high-performance V4 ColdFire microarchitecture featuring an enhanced multiply-accumulate (eMAC) unit, hardware divide and a memory management unit (MMU (Memory Management Unit) The part of the computer that governs memory access. Either part of the CPU chip or housed on separate chips, the MMU controls memory partitions and virtual memory. See memory and virtual memory. MMU - Memory Management Unit ). The MMU allows embedded designers to run protected-mode operating systems, such as Linux OS as well as other third-party real-time OSs (RTOSs). The MCF5445x family devices feature an on-chip DDR (Double Data Rate) Refers to an SDRAM memory chip that increases performance by doubling the effective data rate of the frontside bus. For more details, see SDRAM. DDR - Double Data Rate Random Access Memory memory controller that supports DDR1, DDR2 and mobile DDR memory. Affordable DDR1/2 memory support combined with a cost-effective, non-volatile memory serial interface enables a serial boot capability designed to minimize system cost while maintaining exceptional system performance. The inclusion of a dual-role master/slave serial peripheral interface (communications, hardware) Serial Peripheral Interface - (SPI) A serial interface in which a master device supplies clock pulses to exchanges data serially with a slave over two data wires (Master-Slave and Slave-Master). (SPI (1) (Stateful Packet Inspection) See stateful inspection.
