74 / 79 page ![]() 72 Am29BDD160G June 7, 2006 ERASE AND PROGRAMMING PERFORMANCE Notes: 1. Typical program and erase times assume the following conditions: 25 °C, 2.5 V V CC, 1M cycles. Additionally, programming typicals assume checkerboard pattern. 2. Under worst case conditions of 145°C, V CC = 2.5 V, 100,000 cycles. 3. The typical chip programming time is considerably less than the maximum chip programming time listed. 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 Tables 19 and 20 for further information on command definitions. 6. The device has a minimum erase and program cycle endurance of 1M cycles. 7. PPBs have a minimum program/erase cycle endurance of 100 cycles. LATCHUP CHARACTERISTICS Includes all pins except VCC. Test conditions: VCC = 3.0 V, one pin at a time. PQFP AND FORTIFIED BGA PIN CAPACITANCE Notes: 1. Sampled, not 100% tested. 2. Test conditions TA = 25°C, f = 1.0 MHz.
