Freescale Ships ColdFire MCF5225x Microcontroller with MQX RTOS
Freescale Semiconductor announced a “one-stop-shop” industrial connectivity solution for embedded developers. The solution combines their 32-bit ColdFire microcontroller (MCU) family with the Freescale MQX real-time operating system (RTOS). The combined silicon and software solution gives developers exceptional design flexibility, connectivity options and fast time-to-market backed by a full-featured, scalable RTOS platform valued at approximately $95,000 (USD).
The MCF5225x MCUs ship with full-production Freescale MQX RTOS source code, including communications software stacks, at no additional cost. The RTOS is available to Freescale customers with a commercial-friendly licensing model that enables them to keep their source code modifications. Freescale MQX offers a small, configurable footprint, straightforward application programming interface (API) and a modular architecture that can be fine-tuned to fit a wide range of application needs.
