PERFORMANCE CHARACTERISTICS
This product has been retired and is not available for designs. For new and current designs, S29GL064A supersedes Am29LV640M T/B and is the factory-recommended migration path.
Please refer to the S29GL064A datasheet for specifications and ordering information. Availability of this document is retained for reference and historical purposes only.
Single power supply operation
— 3 V for read, erase, and program operations
Manufactured on 0.23 µm MirrorBit process
technology
Secured Silicon Sector region
— 128-word/256-byte sector for permanent, secure
