4 / 33 page 28F001BX-T28F001BX-B 290406 – 4 Figure 4 PLCC Lead Configuration APPLICATIONS The 28F001BX flash ‘boot block’ memory augments the non-volatility in-system electrical erasure and reprogrammability of Intel’s standard flash memory by offering four separately erasable blocks and inte- grating a state machine to control erase and pro- gram functions The specialized blocking architec- ture and automated programming of the 28F001BX provide a full-function non-volatile flash memory ideal for a wide range of applications including PC bootBIOS memory minimum-chip embedded pro- gram memory and parametric data storage The 28F001BX combines the safety of a hardware-pro- tected 8-KByte boot block with the flexibility of three separately reprogrammable blocks (two 4-KByte pa- rameter blocks and one 112-KByte code block) into one versatile cost-effective flash memory Addition- ally reprogramming one block does not affect code stored in another block ensuring data integrity The flexibility of flash memory reduces costs throughout the life cycle of a design During the early stages of a system’s life flash memory reduces pro- totype development and testing time allowing the system designer to modify in-system software elec- trically versus manual removal of components Dur- ing production flash memory provides flexible firm- ware for just-in-time configuration reducing system inventory and eliminating unnecessary handling and less reliable socketed connections Late in the life cycle when software updates or code ‘‘bugs’’ are often unpredictable and costly flash memory reduc- es update costs by allowing the manufacturers to send floppy updates versus a technician Alterna- tively remote updates over a communication link are possible at speeds up to 9600 baud due to flash memory’s fast programming time 4 |
