Product Details

fido1100 is the first product in the fido™ family of real-time communication controllers. The fido communication controller architecture is uniquely optimized for solving memory bottlenecks, and is designed from the ground up for deterministic processing. Critical timing parameters, such as context switching and interrupt latency, are precisely predictable for real-time tasks. The fido1100 also incorporates the Universal I/O Controller (UIC™) that is configurable to support various communication protocols across multiple platforms. This flexibility relieves the designer of the task of searching product matrices to find the set of peripherals that most closely match the system interface needs. The Software Profiling and Integrated Debug EnviRonment (SPIDER™) has extensive real-time code debug capabilities without the burden of code instrumentation.
