A29L320A AMICC [AMIC Technology], A29L320A Datasheet - Page 42

• Manufacturer Part Number: A29L320A
• Description: 4M X 8 Bit / 2M X 16 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, 100,000 cycles. Additionally,
2. The typical chip programming time is considerably less than the maximum chip programming time listed, since most bytes
3. In the pre-programming step of the Embedded Erase algorithm, all bytes are programmed to 00h before erasure.
4. System-level overhead is the time required to execute the four-bus-cycle command sequence for programming. See Table 9
5. The device has a guaranteed minimum erase and program cycle endurance of 100,000 cycles.
