• Manufacturer Part Number: AM29DL640D
• Description: 64 Megabit CMOS 3.0 Volt-only / Simultaneous Read/Write Flash Memory
• Manufacturer: AMD

ERASE AND PROGRAMMING PERFORMANCE
Notes:
1. Typical program and erase times assume the following conditions: 25 C, 3.0 V V
2. Under worst case conditions of 90 C, V
3. The typical chip programming time is considerably less than the maximum chip programming time listed, since most bytes
4. In the pre-programming step of the Embedded Erase algorithm, all bytes are programmed to 00h before erasure.
5. System-level overhead is the time required to execute the two- or four-bus-cycle sequence for the program command. See Table
6. The device has a minimum erase and program cycle endurance of 1,000,000 cycles.
