2. All V
DD pins must be connected to 3.3V power supply.
3. All V
DDQ pins must be connected to appropriate power supply: 3.3V if OPT pin for that port is set to VIH (3.3V), and 2.5V if OPT pin for that port is set to VIL (0V).
4. All V
SS pins must be connected to ground supply.
5. Package body is approximately 14mm x 20mm x 1.4mm.
6. This package code is used to reference the package diagram.
7. This text does not indicate orientation of the actual part-marking.
8. PIPE/FT option in PK-128 is not supported due to limitation in pin count. Device is pipelined outputs only on each port.
9. Due to the limited pin count, JTAG is not supported in the PK-128 package.

1. A17 is a NC for IDT70V3399.
2. V
DD, OPTX, and VDDQX must be set to appropriate operating levels prior to
applying inputs on the I/Os and controls for that port.
3. OPT
X selects the operating voltage levels for the I/Os and controls on that port.
If OPT
X is set to VIH (3.3V), then that port's I/Os and controls will operate at 3.3V
levels and V
DDQX 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 V
DDQX 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 REPEAT
X is asserted, the counter will reset to the last valid address loaded
via ADS
X.
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 = V
IH, i.e., the
signals take two cycles to deselect.

2. ADS, CNTEN, REPEAT = X.

Truth Table II—Address Counter Control
(1,2)
NOTES:
1. "H" = V
IH, "L" = VIL, "X" = Don't Care.
2. Read and write operations are controlled by the appropriate setting of R/W, CE
0, CE1, UB, LB and OE.
3. Outputs configured in flow-through output mode: if outputs are in pipelined mode the date out will be delayed by one cycle.
4. ADS and REPEAT are independent of all other memory control signals including CE
0, CE1 and UB, LB.
5. The address counter advances if CNTEN = V
IL on the rising edge of CLK, regardless of all other memory control signals including CE0, CE1, UB, LB.
6. When REPEAT is asserted, the counter will reset to the last valid address loaded via ADS. This value is not set at power-up: a known location should be loaded
via ADS during initialization if desired. Any subsequent ADS access during operations will update the REPEAT address location.
