Configuring Stratix II and Stratix II GX Devices

Configuration Scheme
MSEL3
MSEL2
MSEL1
MSEL0
Notes to Table 7–1:
(1) These schemes require that you drive the RUnLU pin to specify either remote update or local update. For more
information about remote system upgrades in Stratix II devices, refer to the Remote System Upgrades With Stratix II
& Stratix II GX Devices chapter in volume 2 of the Stratix II Device Handbook or the Remote System Upgrades With
Stratix II & Stratix II GX Devices chapter in volume 2 of the Stratix II GX Device Handbook.
(2) Only the EPCS16 and EPCS64 devices support up to a 40 MHz DCLK. Other EPCS devices support up to a 20 MHz
DCLK. Refer to the Serial Configuration Devices (EPCS1, EPCS4, EPCS16, EPCS64, and EPCS128) Data Sheet for more
information.
(3) These modes are only supported when using a MAX II device or a microprocessor with flash memory for
configuration. In these modes, the host system must output a DCLK that is 4× the data rate.
(4) Do not leave the MSEL pins floating. Connect them to V_CCPD or ground. These pins support the non-JTAG
configuration scheme used in production. If only JTAG configuration is used, you should connect the MSEL pins to
ground.
(5) JTAG-based configuration takes precedence over other configuration schemes, which means MSEL pin settings are
ignored.
Stratix II and Stratix II GX devices offer design security, decompression,
and remote system upgrade features. Design security using configuration
bitstream encryption is available in Stratix II and Stratix II GX devices,
which protects your designs. Stratix II and Stratix II GX devices can
receive a compressed configuration bit stream and decompress this data
in real-time, reducing storage requirements and configuration time. You
can make real-time system upgrades from remote locations of your
Stratix II and Stratix II GX designs with the remote system upgrade
feature.
Table 7–2 and Table 7–3 show the uncompressed configuration file sizes
for Stratix II and Stratix II GX devices, respectively.
