Product Details

The DK101 is a general-purpose demo kit platform for evaluating Dallas Semiconductor Telecom ICs. The ICs are mounted on daughter cards specifically designed to plug into the DK101's connector. The DK101 provides a microprocessor, flash- and SRAM-based program memory, various oscillators and support logic, and an RS-232 interface to a host PC. As shipped from the factory, the processor runs general-purpose firmware that executes reads and writes to the daughter card on behalf of PC-based demo software. Custom firmware can be downloaded and executed by the processor for advanced applications.
