• Manufacturer Part Number: MT58L64V36F
• Description: (MT58LxxxLxxF) 2Mb SRAM
• Manufacturer: Micron Semiconductor

NOT RECOMENDED FOR NEW DESIGNS
GENERAL DESCRIPTION (continued)
simplify WRITE cycles. This allows self-timed WRITE
cycles. Individual byte enables allow individual bytes
to be written.
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.
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 Flow-Through SyncBurst SRAM
