The CAT25C01/02/04/08/16 is a 1K/2K/4K/8K/16K Bit

SPI Serial CMOS E2PROM internally organized as

128x8/256x8/512x8/1024x8/2048x8 bits. Catalyst’s ad-

vanced CMOS Technology substantially reduces de-

vice power requirements. The CAT25C01/02/04 fea-

tures a 16-byte page write buffer. The 25C08/16 fea-

tures a 32-byte page write buffer.The device operates

via the SPI bus serial interface and is enabled though a

Chip Select (CS). In addition to the Chip Select, the clock

TSSOP Package (U14) SOIC Package (S)

input (SCK), data in (SI) and data out (SO) are required

to access the device. The HOLD pin may be used to

suspend any serial communication without resetting the

serial sequence. The CAT25C01/02/04/08/16 is de-

signed with software and hardware write protection

features including Block Write protection. The device is

available in 8-pin DIP, 8-pin SOIC, 8-pin MSOP and 8/

14-pin TSSOP packages.

*COMMENT

Stresses above those listed under “Absolute Maximum

Ratings” may cause permanent damage to the device.

These are stress ratings only, and functional operation

of the device at these or any other conditions outside of

those listed in the operational sections of this specifica-

tion is not implied. Exposure to any absolute maximum

rating for extended periods may affect device perfor-

mance and reliability.

Note:

(1) The minimum DC input voltage is –0.5V. During transitions, inputs may undershoot to –2.0V for periods of less than 20 ns. Maximum DC

voltage on output pins is VCC +0.5V, which may overshoot to VCC +2.0V for periods of less than 20 ns.

(2) Output shorted for no more than one second. No more than one output shorted at a time.

(3) This parameter is tested initially and after a design or process change that affects the parameter.

(4) Latch-up protection is provided for stresses up to 100 mA on address and data pins from –1V to VCC +1V.
