a burst mode input (MODE) that selects between inter-
leaved and linear burst modes. The data-out (Q), en-
abled 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.
status processor (ADSP#) or address status controller
(ADSC#) inputs. Subsequent burst addresses can be in-
ternally generated as controlled by the burst advance
input (ADV#).
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 DQas and DQPa; BWb# controls DQbs
and DQPb. During WRITE cycles on the x32 and x36
devices, BWa# controls DQas and DQPa; BWb# controls
DQbs and DQPb; BWc# controls DQcs and DQPc; BWd#
TQFP PIN ASSIGNMENT TABLE
NOTE: 1. No Connect (NC) is used on the x32 version. Parity (DQPx) is used on the x36 version.

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.
