CMOS 3.0 Volt-only, Simultaneous Read/Write Flash Memory
For new designs involving TSOP packages, S29JL064H supersedes Am29DL640D and is the factory-recommended migration path. Please refer to the S29JL064H datasheet for specifica-
tions and ordering information. For new designs involving Fine-pitch BGA (FBGA) packages, S29PL064J supersedes Am29DL640D and is the factory-recommended migration path. Please
refer to the S29PL064J Datasheet for specifications and ordering information.
