1.
A17 is a NC for IDT70V3399.
2. VDD, OPTX, and VDDQX must be set to appropriate operating levels prior to
applying inputs on the I/Os and controls for that port.
3. OPTX selects the operating voltage levels for the I/Os and controls on that port.
If OPTX is set to VIH (3.3V), then that port's I/Os and controls will operate at 3.3V
levels and VDDQX must be supplied at 3.3V. If OPTX is set to VIL (0V), then that
port's I/Os and address controls will operate at 2.5V levels and VDDQX must be
supplied at 2.5V. The OPT pins are independent of one another—both ports can
operate at 3.3V levels, both can operate at 2.5V levels, or either can operate
at 3.3V with the other at 2.5V.
4. When
REPEATX is asserted, the counter will reset to the last valid address loaded
via
ADSX.
5. PIPE/
FT option in PK-128 package is not supported due to limitation in pin count.
Device is pipelined output mode only on each port.
6. Chip Enables and Byte Enables are double buffered when PL/
FT = VIH, i.e., the
signals take two cycles to deselect.
