Product Summary

The A29040B-70F is a 5.0 volt-only Flash memory organized as 524,288 bytes of 8 bits each. The 512 Kbytes of data are further divided into eight sectors of 64 Kbytes each for flexible sector erase capability. The A29040B-70F is offered in 32-pin PLCC, TSOP, and PDIP packages. The A29040B-70F is designed to be programmed in-system with the standard system 5.0volt VCC supply. Additional 12.0 volt VPP is not required for in-system write or erase operations. However, the A29040B-70F can also be programmed in standard EPROM programmers.
