Product Summary
The AM29F040B-90PD is a 4 Mbit, 5.0 volt-only Flash memory, which is organized as 524,288 Kbytes of 8 bits each. The 512 Kbytes of data are divided into eight sectors of 64 Kbytes each for flexible erase capability. The 8 bits of data appear on DQ0–DQ7. The AM29F040B-90PD is offered in 32-pin PLCC, TSOP, and PDIP packages. This device is designed to be programmed in-system with the standard system 5.0 volt VCC supply. A 12.0 volt VPP is not required for write or erases operations. The AM29F040B-90PD can also be programmed in standard EPROM programmers.
