				EDI8L3265C
				64Kx32 SRAM
	Features		64Kx32CMOSHighSpeed
	64Kx32 bit CMOS Static		Static RAM
	RandomNOTAccess Memory Array		The EDI8L3265C is a high speed, high performance, four
	•	Fast Access Times: 12*, 15, 20, and 25ns	megabit density Static RAM organized as a 64Kx32 bit
			array.
	•	Individual Byte Selects
			Four Byte Selects, two Chip Enables, Write Control, and
	•	User Configurable Organization	Output Enable provide the user with a flexible memory
		with Minimal Additional Logic	solution. The user may independently enable each of the
			four bytes, and, with minimal additional peripheral logic,
	•	Master Output Enable and Write Control
			the unit may be configured as a 128Kx16 array.
	•	TTL Compatible Inputs and Outputs
			Fully asynchronous circuitry is used, requiring no clocks or
	• Fully Static, No Clocks		refreshing for operation and providing equal access and
	Surface Mount Package		cycle times for ease of use.
			The EDI8L3265C, allows 2 megabits of memory to be
	•	68 Lead PLCC, No. 99 (JEDEC-M0-47AE)
			placed in less than 0.990 square inches of board space.
	• Small Footprint, 0.990 Sq. In.
			The EDI8L3265C can be upgraded to 128K, 256K or
	•	Multiple Ground Pins for Maximum	512Kx32 in the same footprint using the EDI8L32128,
		Noise Immunity	EDI8L32256 or the EDI8L32512C. (See page 6 for up-
			grade paths).
	Single +5V (±5%) Supply Operation
		RECOMMENDEDNote: Solder Reflow temperatures should not exceed 260°C for 10 seconds.
