AM29F040B-70JC

Product Summary

The AM29F040B-70JC is a 4 Mbit, 5.0 volt-only Flash memory 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 AM29F040B-70JC 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. The AM29F040B-70JC offers access times of 55, 70, 90, and 120 ns, allowing high-speed microprocessors to operate without wait states. To eliminate bus contention the device has separate chip enable(CE#), write enable (WE#) and output enable (OE#) controls.
