These Renesas MultiMediaCards, HB28K032MM3, HB28K032RM3, HB28L064MM3, HB28L064RM3, HB28J128MM3, HB28J128RM3, HB28J256MM3, HB28J256RM3 and HB28J512MM3 are highly integrated flash memories with serial and random access capability. It is accessible via a dedicated serial interface optimized for fast and reliable data transmission. This interface allows several cards to be stacked by through connecting their peripheral contacts. These Renesas MultiMediaCards are fully compatible to a new consumer standard, called the MultiMediaCard system standard defined in the MultiMediaCard system specification [1]. The MultiMediaCard system is a new mass-storage system based on innovations in semiconductor technology. It has been developed to provide an inexpensive, mechanically robust storage medium in card form for multimedia consumer applications. MultiMediaCard allows the design of inexpensive players and drives without moving parts. A low power consumption and a wide supply voltage range favor mobile, battery-powered applications such as audio players, organizers, palmtops, electronic books, encyclopedia and dictionaries. Using very effective data compression schemes such as MPEG, the MultiMediaCard will deliver enough capacity for all kinds of multimedia data: software/programs, text, music, speech, images, video etc. Notes: 1.
