Description

The HB28E016BP2 and HB28D032BP2 are Hitachi Mobile Embedded Flashes with MultiMediaCardTM interface, which 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 Hitachi Mobile Embedded Flashes are fully compatible to a new consumer standard, called the MultiMediaCard system standard defined in the MultiMediaCard system specification [1], except the physical outline and the pin assignment.
