Intel’s 28F001BX-B and 28F001BX-T combine the cost-effectiveness of Intel standard flash memory with features that simplify write and allow block erase. These devices aid the system designer by combining the functions of several components into one, making boot block flash an innovative alternative to EPROM and EEPROM or battery-backed static RAM. Many new and existing designs can take advantage of the 28F001BX’s integration of blocked architecture, automated electrical reprogramming, and standard processor interface.
