IDT70V7339S
High-Speed 512K x 18 Synchronous Bank-Switchable Dual-Port Static RAM
Industrial and Commercial Temperature Ranges
Description:
The IDT70V7339 is a high-speed 512Kx18 (9Mbit) synchronous
Bank-Switchable Dual-Ported SRAM organized into 64 independent
8Kx18 banks. The device has two independent ports with separate
control, address, and I/O pins for each port, allowing each port to access
any 8Kx18 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 IDT70V7339 has been optimized for applications having
unidirectional or bidirectional data flow in bursts. An automatic power
down feature, controlled by CE0 andCE1, permits the on-chip circuitry of
each porttoenteraverylowstandbypowermode.Thedualchipenables
also facilitate depth expansion.
The 70V7339 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(VDD) remains at 3.3V. Please refer also to the
functional description on page 18.
