Description

The Hitachi MultiMediaCard HB288032MM1 is a highly integrated flash memory 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. The HB288032MM1 is fully compatible to a new consumer standard, called the MultiMediaCard system standard defined in the MultiMediaCard system specification [1].
