W7G1M32SVx-BN
W7G21M32SVx-BN
Feb. 2004
Rev. 2
PRELIMINARY*
DESCRIPTION
The W7G1M32SVx-BN and W7G21M32SVx-BN are
organized as one and two banks of 1Mx32 respectively.
The modules are based on AMDs AM29LV160DT - 1Mx16
or STs M29W160ET (optional) Flash device in TSOP
packages which are mounted on an FR4 substrate.
Both modules offer access times between 70 and 120ns
allowing for operation of high-speed microprocessors
without wait states.
