Dual chip enables allow for depth expansion without
additional logic
Full synchronous operation on both ports
– 6ns cycle time, 166MHz operation (6Gbps bandwidth)
– Fast 3.6ns clock to data out
– 1.7ns setup to clock and 0.5ns hold on all control, data, and
address inputs @ 166MHz
– Data input, address, byte enable and control registers

IDT70V3319/99S
High-Speed 3.3V 256/128K x 18 Dual-Port Synchronous Static RAM
Industrial and Commercial Temperature Ranges
Description:
The IDT70V3319/99 is a high-speed 256/128K x 18 bit synchronous
Dual-Port RAM. The memory array utilizes Dual-Port memory cells to
allow simultaneous access of any address from both ports. Registers on
control, data, and address inputs provide minimal setup and hold
times. The timing latitude provided by this approach allows systems
to be designed with very short cycle times. With an input data register, the
IDT70V3319/99 has been optimized for applications having unidirectional
or bidirectional data flow in bursts. An automatic power down feature,
controlled by
CE
0
and CE
1,
permits the on-chip circuitry of each port to
enter a very low standby power mode.
The 70V3319/99 can support an operating voltage of either 3.3V or
2.5V on one or both ports, controllable by the OPT pins. The power supply
for the core of the device (V
DD
) remains at 3.3V.

is a NC for IDT70V3399.
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 V
IH
(3.3V), and 2.5V if OPT pin for that port is set to V
IL
(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.

NOTES:
1. A
17
is a NC for IDT70V3399.
2. V
DD
, OPT
X
, and V
DDQX
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 OPT
X
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.
