(Taipei) As part of Alcor's ‘green’ product offering for global energy power saving, Alcor Micro, Corp. (8054) is introducing a series of flash memory card reader controller chips, which belong to Alcor Micro's “Green Family” series. The series include: AU6433 card reader controller chip which supports single-LUN xD/SD/MS memory cards; AU6466 single-LUN Card Reader controller chip which supports all types of memory cards; and AU6476/AU6477 multi-LUN Card Reader controller chip which supports all types of memory cards.
Without a memory card inserted, average stand-alone flash memory card reader or built-in flash memory card reader typically have a power consumption of approx 50mA under idle conditions. The Alcor Micro “Power Saving Mode” flash memory card reader controllers are designed to go into an ‘auto suspend’ power saving mode when a memory card is not inserted into an available slot. With this ‘automatic power suspend’ mode, the average power consumption of a card reader will decrease to an ultra low power consumption of less than 0.3mA. This ultra low power ‘auto suspend’ mode prevents unnecessary power consumption during periods of no memory card usage, and provides measurable system power efficiency improvements for lowered power consumption. With no cards inserted, Alcor's “Green Family” of memory card reader controller chips will reduce nearly 99% of Reader controller power consumption as compared to a regular memory card reader controller.
In addition to the new ‘auto’ power saving mode, The AU6433, AU6466, and AU6476/6477 have an integrated, internal 5V/3.3V/1.8V LDO, reducing the BOM requirements & PCBA size requirements. This new generation Alcor design also incorporates improved EMI performance circuitry for reduced emissions that are typically radiated as part of the newer high speed/high capacity memory cards. The new Alcor hardware Controller solutions are available with a lower and more competitive price as the die size has been reduced.
Alcor's “Green Family” series of flash memory card reader controller chips already has a significant installed base of major OEM & PC companies worldwide. In addition to their outstanding power saving performance, Alcor's Card reader controllers offers the OEM PC industry: overall best memory card compatibility (largest installed base), top rated read/write speeds, lowest external BOM requirements (offering total lowest cost solutions), best value and have an excellent reliability history in one of the industry's largest installed base of internal OEM PC & embedded systems.
