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.

2. Under worst case conditions of 90

°C, V

CC = 2.7 V,

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 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 Table 14 on page 29 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.

TSOP AND BGA PACKAGE CAPACITANCE

Notes:

1. Sampled, not 100% tested.

2. Test conditions T

A = 25°C, f = 1.0 MHz.
