Cyclone II Device Handbook, Volume 1
Cyclone II Architecture
In Cyclone II devices, all the I/O banks support SDR and DDR SDRAM
memory up to 167 MHz/333 Mbps. All I/O banks support DQS signals
with the DQ bus modes of ×8/×9, or ×16/×18. Table 2–14 shows the
external memory interfaces supported in Cyclone II devices.
Cyclone II devices use data (DQ), data strobe (DQS), and clock pins to
interface with external memory. Figure 2–26 shows the DQ and DQS pins
in the ×8/×9 mode.

Notes to Table 2–14:
(1)
The data rate is for designs using the Clock Delay Control circuitry.
(2)
The I/O standards are supported on all the I/O banks of the Cyclone II device.
(3)
The I/O standards are supported only on the I/O banks on the top and bottom of the Cyclone II device.
(4)
For maximum performance, Altera recommends using the 1.8-V HSTL I/O standard because of higher I/O drive
strength. QDRII SRAM devices also support the 1.5-V HSTL I/O standard.
