61 / 69 page  December 16, 2005 Am29LV256M 59 D A TA SH EE T AC CHARACTERISTICS Alternate CE# Controlled Erase and Program Operations Notes: 1. Not 100% tested. 2. See the “Erase And Programming Performance” section for more information. 3. For 1–16 words/1–32 bytes programmed. 4. Effective write buffer specification is based upon a 16-word/32-byte write buffer operation. 5. Word/Byte programming specification is based upon a single word/byte programming operation not utilizing the write buffer. 6. AC listed are tested with V IO = VCC. Contact AMD for information on AC operation with VIO ≠ VCC. 7. When using the program suspend/resume feature, if the suspend command is issued within tPOLL, tPOLL must be fully re-applied upon resuming the programming operation. If the suspend command is issued after t POLL, tPOLL is not required again prior to reading the status bits upon resuming. Parameter Speed Options JEDEC Std.
