AM29F400BT-45

Product Summary

The AM29F400BT-45 is a 4 Mbit, 5.0 volt-only Flash memory organized as 524,288 bytes or 262,144 words. The AM29F400BT-45 is offered in 44-pin SO and 48-pin TSOP packages. The AM29F400BT-45 is also available in Known Good Die (KGD) form. For more information, refer to publication number 21258. The word-wide data(x16) appears on DQ15–DQ0; the byte-wide (x8) data appears on DQ7–DQ0. The AM29F400BT-45 is designed to be programmed in-system with the standard system 5.0 volt VCC supply. A 12.0V VPP is not required for write or erase operations.
