Table 2–14. External Memory Support in Cyclone II Devices
Memory Standard
The data rate is for designs using the Clock Delay Control circuitry.
The I/O standards are supported on all the I/O banks of the Cyclone II device.
The I/O standards are supported only on the I/O banks on the top and bottom of the Cyclone II device.
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.

I/O Standard
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.
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.
