GENERAL DESCRIPTION (continued)
simplify WRITE cycles. This allows self-timed WRITE
cycles. Individual byte enables allow individual bytes
to be written. 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
pins are only available on the x18 and x36 versions.

*Pin 50 is reserved for address expansion.
**No Connect (NC) is used on the x32 version. Parity (DQPx) is used on the x36 version.

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