• Manufacturer Part Number: MT58L64L36D
• Description: (MT58LxxxLxxD) 2Mb SRAM
• Manufacturer: Micron Semiconductor

NOT RECOMENDED FOR NEW DESIGNS
GENERAL DESCRIPTION (continued)
DQc pins and DQPc; BWd# controls DQd pins and
DQPd. GW# LOW causes all bytes to be written. Parity
pins are only available on the x18 and x36 versions.
enable register which delays turning off the output
buffer an additional cycle when a deselect is executed.
This feature allows depth expansion without penaliz-
ing system performance.
TQFP PIN ASSIGNMENT TABLE
*Pin 50 is reserved for address expansion.
**No Connect (NC) is used on the x32 version. Parity (DQPx) is used on the x36 version.
2Mb: 128K x 18, 64K x 32/36 Pipelined, DCD SyncBurst SRAM
