• Manufacturer Part Number: A290011
• Description: 128K X 8 Bit CMOS 5.0 Volt-only, Boot Sector Flash Memory
• Manufacturer: AMICC [AMIC Technology]

Notes:
1. Typical program and erase times assume the following conditions: 25 C, 5.0V VCC, 100,000 cycles. Additionally,
2. Under worst case conditions of 90 C, VCC = 4.5V (4.75V for -55), 100,000 cycles.
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 four-bus-cycle command sequence for programming. See
6. The device has a guaranteed minimum erase and program cycle endurance of 100,000 cycles.
