SMX® RTOS Supports the ColdFire® 521x, 523x, and 527x Families

Costa Mesa, California, June 3, 2005 - Micro Digital Inc. is pleased to announce the availability of the SMX® RTOS for the ColdFire® 521x, 523x, and 527x Processor Families.

Today Micro Digital released SMX for the new ColdFire 5213, 5212, and 5211 microcontrollers, one week after Freescale announced them. The smx high-performance, multitasking kernel includes a new smxBSP specifically for them. It provides startup code and build files, as well as support for interrupts, timers, and UARTs. SMX is a good fit for this ultra-low-cost family of microcontrollers due to its small footprint and high efficiency. Unlike other ColdFires, the 5213 family has very limited memory — 32KB on-chip SRAM and 256KB on-chip flash, with no ability to connect to external memory.

Also, SMX has been recently released for the 523x (5235, 5234, 5233, 5232) and 527x (5275, 5274, 5271, 5270). These are all close cousins to the popular 5282. The 523x is unique in that it is the only ColdFire to feature the eTPU (Enhanced Time Processing Unit).

A free evaluation kit for each of these processor families may be downloaded from All kits include smxCF, smxBSP, smx++, and smxAware for CodeWarrior v5.1. All kits except the 521x kit include smxNet.

Pricing and Availability
