• Manufacturer Part Number: AM28F020
• Description: 2 Megabit (256 K x 8-Bit) CMOS 12.0 Volt/ Bulk Erase Flash Memory
• Manufacturer: Advanced Micro Devices

ERASE AND PROGRAMMING PERFORMANCE
Notes:
1. 25 C, 12 V V
2. Maximum time specified is lower than worst case. Worst case is derived from the Flasherase/Flashrite pulse count
