CXK58257ATM/AYM

-70L/10L

-70LL/10LL

32768-word x 8-bit High Speed CMOS Static RAM

Description

CXK58257ATM/AYM is a 256K-bit, 32,768-word-by-

8-bit, CMOS static RAM.

It is suitable for portable and battery back-up systems

which require extremely small packages and low

stand-by current.

Features

• Thin small-outline package:

CXK58257ATM:

8mm x 13.4mm, 28 pin TSOP

CXK58257AYM:

8mm x 13.4mm, 28 pin TSOP

(Mirror image pinout)

• Low stand-by current:

L-Version:

25µA (max.) @V

= 5.5V, Ta = 0 to +70°C

LL-Version:

5µA (max.) @V

= 5.5V, Ta = 0 to +70°C

• Low voltage data retention: 2.0V (min.)

• Fast access time:

(Access time)

CXK58257ATM/AYM-70L, -70LL

70ns (max.)

CXK58257ATM/AYM-10L, -10LL

100ns (max.)

• Single + 5V supply: 5V ± 10 %
