GENERALDESCRIPTION  
The Micron® SyncBurstSRAM family employs  
high-speed, low-power CMOS designs that are fabri-  
cated using an advanced CMOS process.

Micron’s 2Mb SyncBurst SRAMs integrate a 128K x  
18, 64K x 32, or 64K x 36 SRAM core with advanced  
synchronous peripheral circuitry and a 2-bit burst  
counter. All synchronous inputs pass through registers  
controlled by a positive-edge-triggered single clock  
input (CLK). The synchronous inputs include all ad-  
dresses, all data inputs, active LOW chip enable (CE#),  
two additional chip enables for easy depth expansion  
(CE2, CE2#), burst control inputs (ADSC#, ADSP#,  
ADV#), byte write enables (BWx#) and global write  
(GW#).  
Asynchronous inputs include the output enable  
(OE#), snooze enable (ZZ) and clock (CLK). There is also  
a burst mode pin (MODE) that selects between inter-  
leaved and linear burst modes. The data-out (Q), en-  
abled by OE#, is also asynchronous. WRITE cycles can  
be from one to two bytes wide (x18) or from one to four  
bytes wide (x32/x36), as controlled by the write control  
inputs.

Part Number Example:  
MT58L64L36FT-8.5  
Burst operation can be initiated with either address  
status processor (ADSP#) or address status controller  
(ADSC#) input pins. Subsequent burst addresses can be  
internally generated as controlled by the burst advance  
pin (ADV#).
