64Kx32 CMOS High Speed
Static RAM
The EDI8L3265C is a high speed, high performance, four
megabit density Static RAM organized as a 64Kx32 bit
array.
Four Byte Selects, two Chip Enables, Write Control, and
Output Enable provide the user with a flexible memory
solution. The user may independently enable each of the
four bytes, and, with minimal additional peripheral logic,
the unit may be configured as a 128Kx16 array.
Fully asynchronous circuitry is used, requiring no clocks or
refreshing for operation and providing equal access and
cycle times for ease of use.
The EDI8L3265C, allows 2 megabits of memory to be
placed in less than 0.990 square inches of board space.
The EDI8L3265C can be upgraded to 128K, 256K or
512Kx32 in the same footprint using the EDI8L32128,
EDI8L32256 or the EDI8L32512C. (See page 6 for up-
grade paths).
Note: Solder Reflow temperatures should not exceed 260°C for 10 seconds.
