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

and CE

, 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

) remains at 3.3V. Please refer also to the

functional description on page 19.

NOTES:
1. V

, OPT

, 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

selects the operating voltage levels for the I/Os and controls on that port.

If OPT

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

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

is asserted, the counter will reset to the last valid address loaded

via

ADS

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

- BA

). 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).

(1,2,7)

NOTES:
1. "H" = V

IH,

"L" = V

IL,

"X" = Don't Care.

2. Read and write operations are controlled by the appropriate setting of R/

W, CE

, CE

BEn and OE.

3. Outputs configured in flow-through output mode: if outputs are in pipelined mode the data out will be delayed by one cycle.
4.

ADS and REPEAT are independent of all other memory control signals including CE

, CE

and

BEn

5. The address counter advances if

CNTEN = V

on the rising edge of CLK, regardless of all other memory control signals including

, CE

BEn.

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.

7. The counter includes bank address and internal address. The counter will advance across bank boundaries. For example, if the counter is in Bank 0, at address

FFFh, and is advanced one location, it will move to address 0h in Bank 1. By the same token, the counter at FFFh in Bank 63 will advance to 0h in Bank 0. Refer
to Timing Waveform of Counter Repeat, page 18. Care should be taken during operation to avoid having both counters point to the same bank (i.e., ensure BA

- BA

), as this condition will invalidate the access for both ports. Please refer to the functional description on page 19 for details.

3. The "Internal Address" is equal to the "External Address" when

4. No dead cycle exists during

REPEAT operation. A READ or WRITE cycle may be coincidental with the counter REPEAT cycle: Address loaded by last valid

ADS load will be accessed. For more information on REPEAT function refer to Truth Table II.

CNTEN = V

advances Internal Address from `An' to `An +1'. The transition shown indicates the time required for the counter to advance. The `An +1'Address is

written to during this cycle.

6. The counter includes bank address and internal address. The counter will advance across bank boundaries. For example, if the counter is in Bank 0, at address

FFFh, and is advanced one location, it will move to address 0h in Bank 1. By the same token, the counter at FFFh in Bank 63 will advance to 0h in Bank 0.

7. For Pipelined Mode user should add 1 cycle latency for outputs as per timing waveform of read cycle for pipelined operations.

IDT70V7519S
High-Speed 256K x 36 Synchronous Bank-Switchable Dual-Port Static RAM Industrial and Commercial Temperature Ranges

Functional Description

The IDT70V7519 is a high-speed 256Kx36 (9 Mbit) synchronous

Bank-Switchable Dual-Ported SRAM organized into 64 independent
4Kx36 banks. Based on a standard SRAM core instead of a traditional true
dual-port memory core, this bank-switchable device offers the benefits of
increased density and lower cost-per-bit while retaining many of the
features of true dual-ports. These features include simultaneous, random
access to the shared array, separate clocks per port, 166 MHz operating
speed, full-boundary counters, and pinouts compatible with the IDT70V3599
(128Kx36) dual-port family.

The two ports are permitted independent, simultaneous access into

separate banks within the shared array. Access 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

- BA

). 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).

The IDT70V7519 provides a true synchronous Dual-Port Static RAM

interface. Registered inputs provide minimal setup and hold times on
address, data and all critical control inputs.

An asynchronous output enable is provided to ease asynchronous

bus interfacing. Counter enable inputs are also provided to stall the
operation of the address counters for fast interleaved memory applications.

A HIGH on

or a LOW on CE

for one clock cycle will power down

the internal circuitry on each port (individually controlled) to reduce static
power consumption. Dual chip enables allow easier banking of multiple
IDT70V7519s for depth expansion configurations. Two cycles are
required with

LOW and CE

HIGH to read valid data on the outputs.

Depth and Width Expansion

The IDT70V7519 features dual chip enables (refer to Truth

Table I) in order to facilitate rapid and simple depth expansion with no
requirements for external logic. Figure 4 illustrates how to control the
various chip enables in order to expand two devices in depth.

The IDT70V7519 can also be used in applications requiring expanded

width, as indicated in Figure 4. Through combining the control signals, the
devices can be grouped as necessary to accommodate applications
needing 72-bits or wider.

NOTE:
1. In the case of depth expansion, the additional address pin logically serves as an extension of the bank address. 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 within the shared array that is not currently
being accessed by the opposite port (i.e., BA

- BA

). 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 parts within that bank may be corrupted (in the case that either or both parts are
writing) or may result in invalid output (in the case that both ports are trying to read).
