52 / 59 page  50 Am29LV320MH/L 26517B4 January 31, 2007 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 specifications 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 t POLL, tPOLL must be fully re-applied upon resuming the programming operation. If the suspend command is issued after tPOLL, tPOLL is not required again prior to reading the status bits upon resuming. Parameter Speed Options JEDEC Std.
