This document describes the DOFF issue for QDRII/DDRII and the Output Buffer and JTAG issues for
QDRI/DDRI/QDRII/DDRII. Details include trigger conditions, possible workarounds and silicon revision applicability.
This document should be used to compare to the respective datasheet for the devices to fully describe the device
functionality.
Please contact your local Cypress Sales Representative for availability of the fixed devices and any other questions.

Fix Status
1.
DOFF pin is used for enabling/dis-
abling the DLL circuitry within the
SRAM. To enable the DLL circuitry,
DOFF pin must be externally tied
HIGH. The QDR-II/DDR-II devices
have an internal pull down resistor of
~5K
. The value of the external pull-
up resistor should be 500
order to ensure DLL is enabled.

QDR-II/DDR-II Devices
The fix involved removing the in-
ternal pull-down resistor on the
DOFF pin. The fix has been im-
plemented on the new revision
and is now available.
