Freescale Semiconductor has added four ColdFire families – MCF547x, MCF548x, MCF523x and MCF527x – made up of more than 20 processors. These families of embedded 32-bit microprocessors are designed to reduce memory requirements, power dissipation, system board size and costs in a variety of industrial applications.
With the release of these devices, Freescale is providing customers with high-performance processors that enable multiple levels of integration – all adaptable and easily integrated with memories, systems modules and peripherals.
Application examples range from large-scale factory automation to more precise medical instrumentation. Whether for robotics, security, retail point-of-sale scanners and terminals or other commercial implementations, these ColdFire devices enable a consistent level of protection, connectivity and control.
Capabilities not in previous ColdFire devices include an enhanced Time Processing Unit (eTPU).
The MCF547x and MCF548x families of microprocessors – the first to feature the V4e ColdFire core – are some of the most highly integrated ColdFire standard products to date. These devices provide a selection of connectivity with robust encryption options. Devices from these V4e-based families are capable of delivering up to 410MIPS at 266MHz. The MCF548x meets industrial temperature demands and is the only dual-CAN (controller area network), dual Ethernet processor available today.
The MCF523x family, based on the V2 ColdFire core, is designed specifically for embedded industrial control and motor control applications that require connectivity.
Along with the eTPU, this family features a real-time control co-processor dedicated to performing high-speed, complex timing and input/output, freeing up the central processing unit for other tasks.
The MCF523x family also serves as a natural migration path and upgrade for Freescale MC68332 customers requiring higher performance and/or networking support.
Other on-chip features include integrated CAN and Ethernet interfaces along with cryptography acceleration for cost-effective processors used in networked and stand-alone complex real-time control applications.
The ColdFire core on these families includes an enhanced Multiply-Accumulate Unit (eMAC) providing significant performance with 144MIPS (Dhrystone 2.1) at 150MHz.The MCF527x family builds upon the peripheral mix of the MCF5272 processor to provide a powerful combination of connection, protection and peripheral selection.
This family is designed for cost-sensitive applications that require significant control processing for file management, connectivity, data buffering, user interface and signal processing in a variety of key markets such as security, imaging, networking and gaming.
These devices provide an upgrade at no additional cost for current MCF5272 users – with added performance, a second 10/100Mbps Ethernet MAC and hardware encryption to ensure the application can enable secure communication.
Through partnerships with tool suppliers, including Metrowerks/ARC, Green Hills, Wind River and other independent development tool suppliers, customers have access to broad operating system support (including Metrowerks Linux, as well as evaluation boards and other hardware and software development tools as well upgrades from 68k devices.
