General Description
MiDAS1.0B family offers very fast performance available in 80C52-compatible microcontroller. It features a newly-designed processor core that executes each instruction up-to 3 times faster than original 80C52 processor for the same clock speed. CORERIVER Technology offers not only the chips but also its user-friendly development tools such like 1) MDS (MCU Development System), 2) S/W generation and debugging tools including optimizing C-compiler, 3) Application system, and 4) Easy to Use training kit system
Application Areas
Motor Control, Consumer Electronics, Gaming Equipment, Home Appliance (Washers, Microwaves, etc.) Building Security and Door Access Control, Building Energy Control and Management, Industrial Control and Automation.
