ERASE AND PROGRAMMING PERFORMANCE

Notes:

1. Typical program and erase times assume the following conditions: 25

°C, 5.0 V V

CC, 1,000,000 cycles. Additionally,

programming typicals assume checkerboard pattern.

2. Under worst case conditions of 90°C, VCC = 4.5 V (4.75 V for -55), 1,000,000 cycles.

3. The typical chip programming time is considerably less than the maximum chip programming time listed, since most bytes

program faster than the maximum byte program time listed. If the maximum byte program time given is exceeded, only then

does the device set DQ5 = 1. See the section on DQ5 for further information.

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 Table 4

for further information on command definitions.

6. The device has a guaranteed minimum erase and program cycle endurance of 1,000,000 cycles.

LATCHUP CHARACTERISTICS

Includes all pins except VCC. Test conditions: VCC = 5.0 V, one pin at a time.

TSOP PIN CAPACITANCE

Notes:

1. Sampled, not 100% tested.

2. Test conditions TA = 25°C, f = 1.0 MHz.
