are read addresses and A2 and A4 are write addresses. For pipelined
ZBT SRAM operation, data is delayed by another clock cycle. Stratix and
Stratix GX devices support up to 200-MHz ZBT SRAM operation using
the 2.5-V or 3.3-V LVTTL I/O standard.
Interface Pins
ZBT SRAM uses one system clock input for all clocking purposes. Only
the rising edge of this clock is used, since ZBT SRAM uses a single data
rate scheme. The data bus, DQ, is bidirectional. There are three control
signals to the ZBT SRAM: RW_N, BW_N, and ADV_LD_N. You can use any
of the Stratix and Stratix GX device user I/O pins to interface to the
ZBT SRAM device.
