Specifications

Two variations of RTX166 are available.

• The RTX166 Real-Time Kernel is a full-blown real-time kernel with support for multiple events, numerous tasks, various methods of inter-task communication, and flexible configuration options. RTX166 Full is available as a stand-alone product (part number FR166).
• The RTX166 Tiny Real-Time Kernel is a high-performance, low-overhead kernel designed for single-chip applications. RTX166 Tiny is included with the PK166 Professional Developer's Kit.
