Designed to meet the demands of the expanding embedded network-connected control market by offering high performance and multiple connectivity peripherals to help enable cost-effective system solutions, the MCF547x and MCF548x families of ColdFire microprocessors from Motorola Inc. enable simultaneous control, connectivity and security.

Claimed by the company as the highest performing and most integrated ColdFire standard products to date, the devices are the first to feature the V4e ColdFire core, which is capable of delivering up to 410MIPS (Dhrystone 2.1) at 266MHz.

The V4e ColdFire core also integrates a Memory Management Unit (MMU), a double-precision floating point unit (FPU), an enhanced multiply-accumulate unit (EMAC), and controllers for caches and local data memories.

The MCF547x and MCF548x processors also feature extensive connectivity options, including Ethernet, USB, CAN, PCI and other serial interfaces. The devices meet the need for secure point-to-point communications across open networks with a range of standard Internet security protocols such as SSL/TLS, IPsec, IKE, and WTLS/WAP. To address the computational bandwidth requirements of these Internet security protocols, as well as to accelerate core cryptography algorithms, the company has developed the cryptography accelerator module on the processors.

Targeted for use in security/access control systems, point-of-sale (POS) systems, network-attached storage, SOHO networking applications, and factory automation, building control and process automation systems, the processors feature a 32KB I-Cache and 32KB D-Cache, up to two 10/100 Ethernet controllers, a 32-bit v2.2 PCI interface 33MHz or 66MHz, 32KB of on-chip SRAM, a 16-channel DMA controller, four 32-bit timers, two 32-bit slice timers, one watchdog timer, and two CAN 2.0B (MCF548x).

A USB 2.0 high-speed device with integrated PHY and hardware-accelerated encryption (DES, 3DES, RC4, AES, MD5, SHA-1 and RNG) are optional features.

Suggested list prices in 10,000-piece quantities start at $16.95.
