High-Speed 256K x 18 Synchronous Bank-Switchable Dual-Port Static RAM Industrial and Commercial Temperature Ranges
Description:
The IDT70V7319 is a high-speed 256Kx18 (4Mbit) synchronous
Bank-Switchable Dual-Ported SRAMorganized into 64 independent
4Kx18 banks. The device has two independent ports with separate
control, address, and I/O pins for each port, allowing each port to access
any 4Kx18 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 mnimal setup
and hold times. The timng latitude provided by this approach allows
systems to be designed with very short cycle times. With an input data

,
register, the IDT70V7319 has been optimzed for applications having
unidirectional or bidirectional data flow in bursts. An automatic power down
feature, controlled by CE
0
and CE
1
, permts the on-chip circuitry of each
port to enter a very low standby power mode. The dual chip enables also
facilitate depth expansion.
The 70V7319 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.
