NOR Flash ICs

The A29001A is a 5.0 volt-only Flash memory organized as 131,072 bytes of 8 bits each. The A29001A offers the RESET function, but it is not available on A290011A. The 128 Kbytes of data are further divided into seven sectors for flexible sector erase capability. The 8 bits of data appear on I/O0 - I/O7 while the addresses are input on A0 to A16. The A29001A is offered in 32-pin PLCC, PDIP and TSOP packages. This device is designed to be programmed insystem with the standard system 5.0 volt VCC supply. Additional 12.0 volt VPP is not required for in-system write or erase operations. However, the A29001A can also be programmed in standard EPROM programmers.

The A29L040A is a 3.0 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 8 bits of data appear on I/O0 - I/O7 while the addresses are input on A0 to A18. The A29L040A is offered in 32-pin DIP, PLCC, TSOP (8mm x 20mm) packages. This device is designed to be programmed in-system with the standard system 3.0 volt VCC supply. Additional 12.0 volt VPP is not required for in-system write or erase operations. However, the A29L040A can also be programmed in standard EPROM programmers.
