42 / 48 page 42 Am29LV800T/Am29LV800B PRELIMINARY ERASE AND PROGRAMMING PERFORMANCE Notes: 1. The typical program and erase times are considerably less than the maximum times since most words/bytes program or erase significantly faster than the worst case word/byte. The device enters the failure mode (DQ5=“1”) only after the maximum times given are exceeded. See the section on DQ5 for further information. 2. Except for erase and program endurance, the typical program and erase times assume the following conditions: 25 °C, 3.0 V VCC, 100,000 cycles. Additionally, programming typicals assume checkerboard pattern. 3. Under worst case conditions of 90˚C, VCC = 2.7 V, 100,000 cycles. 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 sequence for the program command. See Table 6 for further information on command definitions. LATCHUP CHARACTERISTICS Includes all pins except VCC. Test conditions: VCC = 3.0 V, one pin at a time. PIN CAPACITANCE, 48-PIN TSOP Notes: 1. Sampled, not 100% tested. 2. Test conditions TA = 25°C, f = 1.0 MHz.
