Feature  Erase/Write Lockout during Power Transitions  Absolute Hardware Protection for Boot Block Software EEPROM Emulation with Parameter Blocks n n n n n Intel’s 2-Mbit flash memory is an extension of the Boot Block architecture which includes block-selective erasure, automated write and erase operations, and a standard microprocessor interface. The 2-Mbit flash memory enhances the Boot Block architecture by adding more density and blocks, x8 input/output control, very high-speed, low-power, and industry-standard ROM-patible pinout and surface mount packaging. The Intel 28F002BC is an 8-bit wide flash memory offering. This high-density flash memory provides userselectable bus operation for 8-bit applications. The 28F002BC is a 2,097,152-bit nonvolatile memory organized as 262,144 bytes of information. It is offered in 44-lead PSOP, 40- lead PDIP and 40-lead TSOP package, which is ideal for space-constrained portable systems or any application with board space limitations. This device uses an integrated mand User Interface (CUI) and Write State Machine (WSM) for simplified byte write and block erasure. The 28F002BC provides block locations patible with Intel’s MCS®-186 family, 80286, 90860CA, and the Intel386™, Intel486™, Pentium®, and Pentium Pro microprocessors. The boot block includes a data protection feature to protect the boot code in critical applications. With a maximum access time of 80 ns, this high-performance 2-Mbit flash memory interfaces at zero wait-state to a wide range of microprocessors and microcontrollers. A deep power-down mode lowers the total VCC power consumption to 1 µW typical. This power savings is critical in hand-held battery powered systems. For very low-power applications using a 3.3V supply, refer to the Intel 28F002BV-T/B 2-Mbit Smart Voltage Boot Block Flash Memory datasheet. Manufactured on Intel’s 0.6 micron ETOX™ IV process technology, the 28F002BC flash memory provides world-class quality,...
