NOTE:
1. The Bank-Switchable dual-port uses a true SRAM
core instead of the traditional dual-port SRAM core.
As a result, it has unique operating characteristics.

IDT70V7519S
High-Speed 256K x 36 Synchronous Bank-Switchable Dual-Port Static RAM
Industrial and Commercial Temperature Ranges
Description:
The IDT70V7519 is a high-speed 256Kx36 (9Mbit) synchronous
Bank-Switchable Dual-Ported SRAM organized into 64 independent
4Kx36 banks. The device has two independent ports with separate
control, address, and I/O pins for each port, allowing each port to access
any 4Kx36 memory block not already accessed by the other port.
Accesses by the ports into specific banks are controlled via the bank
address pins under the user's direct control.
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 IDT70V7519 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 dual chip enables also
facilitate depth expansion.
The 70V7519 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. Please refer also to the
functional description on page 19.

NOTES:
1. All V
DD
pins must be connected to 3.3V power supply.
2. 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).
3. All V
SS
pins must be connected to ground supply.
4. Package body is approximately 28mm x 28mm x 3.5mm.

NOTES:
1. 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.
2. 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.
3. When
REPEAT
X
is asserted, the counter will reset to the last valid address loaded
via
ADS
X
.
4. Accesses by the ports into specific banks are controlled by the bank address
pins under the user's direct control: each port can access any bank of memory
with the shared array that is not currently being accessed by the opposite port
(i.e., BA
0L
- BA
5L
≠
BA
0R
- BA
5R
). In the event that both ports try to access the
same bank at the same time, neither access will be valid, and data at the two
specific addresses targeted by the ports within that bank may be corrupted (in
the case that either or both ports are writing) or may result in invalid output (in
the case that both ports are trying to read).
