Refrigerators Freezers
Overview Home appliance controls changing from purely mechanical fully electronic microcontrollers incorporated into designs. migration industry from mechanical electromechanical control, then full electronic control been ongoing several years. Today, microcontrollers provide intelligence every electronic solution. primary reasons driving adoption electronics reliability, cost, improved energy efficiency. Continually operating, refrigerators account much energy consumed average household. energy efficiency refinement refrigerators result real savings consumer. Microcontrollers crucial maximizing appliance efficiency while supporting variety features. Benefits Provides quieter operation with improved power efficiency refrigerators freezers Improves compressor control brushless motor control while improving energy Monitors moisture levels inside appliance cavity

Design Challenges Cost appliance market highly competitive cost sensitive. Eliminating just cents from cost solution save thousands dollars this high-volume market. Flexibility model introduced every year while recent products displayed. This means software problems must eliminated quickly, which requires professional development tools faster, more efficient development cycles.
Legislation Energy efficiency regulations driving manufacturers redesign their products meet global legislative demands. Measurement Accuracy Measuring temperatures different interior zones refrigerator freezer critical performance. example, vegetable drawer should different temperature than dairy shelf.
SG2038-2
Freescale Semiconductor Solution Freescale Semiconductor industry leader Flash microcontrollers. Flash memory nonvolatile memory (NVM) technology that provides access following features: Faster programming erase times Flash memory with reprogram capability In-application programming, which reduces time market Improved write/erase data retention performance Flash Flexible block protection security Emulation EEPROM Flash
Embedded Flash brings flexibility your designs: Provides end-of-line customization regional variations consumer demands Enables changing legislation satisfied with software-enabled intelligence Supports remote diagnostics preventative maintenance Minimizes programming costs while increasing code flexibility with production line programming Reduces obsolescence, which saves scrapped product costs
Improves time market, which reduces lead times Standardizes platforms, which reduces product variability Eliminates sockets rework with in-system programmable Flash Provides field upgrade capability while allowing remote reprogramming microcontroller Eliminates need external EEPROM with 10,000 write/erase cycles because Flash emulate EEPROM
