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-compatible pinout and surface mount packaging.
The Intel 28F002BC is an 8-bit wide flash memory offering. This high-density flash memory provides user-
selectable 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 Command User Interface (CUI) and Write State Machine (WSM) for simplified
byte write and block erasure. The 28F002BC provides block locations compatible 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 V
CC
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

datasheet. Manufactured on Intel’s 0.6 micron ETOX™ IV process technology, the 28F002BC
flash memory provides world-class quality, reliability, and cost-effectiveness at the 2-Mbit density.
