FEATURES  
• Fast clock and OE# access times  
100-Pin TQFP*  
• Single +3.3V +0.3V/-0.165V power supply (VDD)  
• Separate +3.3V +0.3V/-0.165V isolated output buffer  
supply (VDDQ)  
• SNOOZE MODE for reduced-power standby  
• Common data inputs and data outputs  
• Individual BYTE WRITE control and GLOBAL WRITE  
• Three chip enables for simple depth expansion and  
address pipelining  
• Clock-controlled and registered addresses, data I/Os  
and control signals  
• Internally self-timed WRITE cycle  
• Burst control pin (interleaved or linear burst)  
• Automatic power-down for portable applications  
• 100-lead TQFP package for high density, high speed  
• Low capacitive bus loading  
*JEDEC-standard MS-026 BHA (LQFP).  
• x18, x32 and x36 versions available

(CLK). The synchronous inputs include all addresses, all  
data inputs, active LOW chip enable (CE#), two additional  
chip enables for easy depth expansion (CE2, CE2#), burst  
controlinputs(ADSC#, ADSP#, ADV#), bytewriteenables  
(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 interleaved and  
linear burst modes. The data-out (Q), enabled 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.  
Burstoperationcanbeinitiatedwitheitheraddressstatus  
processor (ADSP#) or address status controller (ADSC#)  
input pins. Subsequent burst addresses can be internally  
generated as controlled by the burst advance pin (ADV#).  
Address and write control are registered on-chip to  
simplifyWRITEcycles.Thisallowsself-timedWRITEcycles.  
Individualbyteenablesallowindividualbytestobewritten.  
During WRITE cycles on the x18 device, BWa# controls  
DQa pins and DQPa; BWb# controls DQb pins and DQPb.  
During WRITE cycles on the x32 and x36 devices, BWa#  
controls DQa pins and DQPa; BWb# controls DQb pins and  
DQPb; BWc# controls DQc pins and DQPc; BWd# controls  
DQd pins and DQPd. GW# LOW causes all bytes to be  
written. Parity bits are only available on the x18 and x36  
versions.

GENERAL DESCRIPTION  
The Micron SyncBurst SRAM family employs high-  
speed, low-power CMOS designs that are fabricated using  
an advanced CMOS process.  
The MT58L64L18F and MT58L32L32/36F 1Mb SRAMs  
integrate a 64K x 18, 32K x 32, or 32K x 36 SRAM core with  
advanced synchronous peripheral circuitry and a 2-bit  
burstcounter.Allsynchronousinputspassthroughregisters  
controlled by a positive-edge-triggered single clock input
