MCUs Deliver Cost-Effective Connectivity and Ultra-Low Power

Freescale Semiconductor has added ten highly integrated MicroController Units (MCUs) to its extensive 32-bit ColdFire® portfolio. The new devices provide developers with a broad range of cost-effective, low-power and connectivity options, coupled with comprehensive software solutions.



The expanded ColdFire lineup includes extensions to the MCF5223x Ethernet MCU family, the MCF5221x USB MCU family and the MCF51QE ultra-low-power family. Target applications include security control panels, barcode scanners, medical pumps/monitors, environmental monitoring, and battery operated devices.

Part of Freescale's controller continuum roadmap for compatible 8- and 32-bit architectures, the devices provide pin, tool and peripheral compatibility with other ColdFire MCUs, offering an easy migration path to higher performance and integration. The MCF51QE32 is a 8/32-bit (‘Flexis’) compatible MCU, whereas the new MCF5223x & MCF5221x devices do NOT have 8-bit equivalents but are compatible with existing ColdFire family members.

Additions to the MCF5221x USB-enabled family give designers more memory and performance options, including SRAM capacity of up to 8KByte and up to 128Kbyte Flash. Like the entire USB device family, the four new chips include a USB On-The-Go (OTG) Full Speed module, giving designers the option of use in device or host mode. Integrated transceivers eliminate the need for external components and the devices draw just 6µA in standby mode and 10µA in low-power run mode.

The USB products are also supported with a software stack, supporting several Human Interface Device (HID), Communications Device Class (CDC) to UART, and host mass storage projects. Both the Ethernet and USB stacks interface directly to Freescale Semiconductor's CodeWarrior Development Studio to provide a full-featured software solution and a solid platform for application development.

Freescale Semiconductor has also added two devices to the low-power Flexis QE range of devices. With up to 8KByte SRAM and 32KByte Flash, they are pin compatible with other devices in the family, providing an easy migration path to higher memory densities. With run mode power consumption of 27mA, low-power run mode consumption of 50µA, stop current of just 370nA and wake-up time of 6µs, these devices address the growing market for battery-powered systems, portable devices and energy-efficient green products.

All the new MCF5223x and MCF5221x MCUs are supported by the latest version of the CodeWarrior for ColdFire V7.0 Integrated Development Environment (IDE) which now includes Processor Expert, a GUI based peripheral initialisation tool for simplifying code development. Furthermore, demonstration and evaluation boards are supplied with supplementary training materials such as software examples and application notes to assist designers.
