4-Mbit (256K x 16, 512K x 8) Low-Power Boot Block Flash Memory Family 28F400BL-T/B, 28F004BL-T/B

The Intel 28F400BL-T/B are 16-bit wide low power flash memory offerings. These high density flash memories provide user selectable bus operation for either 8-bit or 16-bit applications. The 28F400BL-T and 28F400BL-B are 4,194,304-bit non-volatile memories organized as either 524,288 bytes or 262,144 words of information. They are offered in 44-Lead PSOP and 56-Lead TSOP packages. The x8/x16 pinout conforms to the industry standard ROM/EPROM pinout. The Intel 28F004BL-T/B are 8-bit wide low power flash memories with 4,194,304 bits organized as 524,288 bytes of information. They are offered in a 40-Lead TSOP package, which is ideal for space-constrained portable systems. These devices use an integrated Command User Interface (CUI) and Write State Machine (WSM) for simplified word/byte write and block erasure. The 28F400BL-T/28F004BL-T provide block locations compatible with Intel's Low Voltage MCS-186 family, i386(TM) , i486(TM) microprocessors. The 28F400BL-B/28F004BL-B provide compatibility with Intel's 80960KX and 80960SX families as well as other low voltage embedded microprocessors.
