Product Summary
The AM29LV641DL-90REI is a 64 Mbit, 3.0 Volt (3.0 V to 3.6 V) single power supply flash memory device organized as 4,194,304 words. Data appears on DQ0-DQ15. The device is designed to be programmed in-system with the standard system 3.0 volt VCC supply. A 12.0 volt VPP is not required for program or erase operations. The AM29LV641DL-90REI can also be programmed in standard EPROM programmers. Access times of 90 and 120 ns are available for applications where VIO ≥ VCC.
