• Manufacturer Part Number: mt58l64v32f
• Description: 2mb 128k X 18, 64k X 32/36 Flow-through Syncburst Sram
• Manufacturer: Micron Semiconductor Products

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.
+3.3V V
TTL-compatible. Users can choose either a 3.3V or 2.5V
I/O version. The device is ideally suited for 486,
Pentium
that benefit from a very wide data bus. The device is also
ideal in generic 16-, 18-, 32-, 36-, 64-, and 72-bit-wide
applications.
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.
