ERASE AND PROGRAMMING PERFORMANCE

Notes:

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

°C, 3.0 V V

CC, 1,000,000 cycles. Additionally,

programming typicals assume checkerboard pattern. All values are subject to change.

2. Under worst case conditions of 90

°C, V

CC = 2.7 V, 1,000,000 cycles. All values are subject to change.

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

program faster than the maximum program times 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

Table 13 for further information on command definitions.

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

LATCHUP CHARACTERISTICS

Note: Includes all pins except V

CC. Test conditions: VCC = 3.0 V, one pin at a time.

BGA PIN CAPACITANCE

Notes:

1. Sampled, not 100% tested.

2. Test conditions T

A = 25°C, f = 1.0 MHz.
