• Manufacturer Part Number: A29L008ATV-70
• Description: 1M X 8 Bit CMOS 3.0 Volt-only, Boot Sector Flash Memory
• Manufacturer: AMICC [AMIC Technology]

Notes:
1. Typical program and erase times assume the following conditions: 25°C, 3.0V VCC, 10,000 cycles. Additionally, programming
2. Under worst case conditions of 90°C, VCC = 2.7V, 100,000 cycles.
3. The typical chip programming time is considerably less than the maximum chip programming time listed, since most program
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 four-bus-cycle command sequence for programming. See Table 5
6. The device has a guaranteed minimum erase and program cycle endurance of 10,000 cycles.
