Description
The IDT71V016 is a 1,048,576-bit high-speed Static RAM organized
as 64K x 16. It is fabricated using IDT’s high-perfomance, high-reliability
CMOS technology. This state-of-the-art technology, combined with inno-
vative circuit design techniques, provides a cost-effective solution for high-
speed memory needs.
The IDT71V016 has an output enable pin which operates as fast
as 5ns, with address access times as fast as 10ns. All bidirectional
inputs and outputs of the IDT71V016 are LVTTL-compatible and operation
is from a single 3.3V supply. Fully static asynchronous circuitry is used,
requiring no clocks or refresh for operation.
The IDT71V016 is packaged in a JEDEC standard 44-pin Plastic
SOJ, a 44-pin TSOP Type II, and a 48-ball plastic 7 x 7 mm FBGA.

NOTE:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.
NOTES:
1. For 71V016SA10 only.
2. For all speed grades except 71V016SA10.
3. VIH (max.) = VDD+2V for pulse width less than 5ns, once per cycle.
4. VIL (min.) = –2V for pulse width less than 5ns, once per cycle.
NOTE:
1. This parameter is guaranteed by device characterization, but not production tested.
NOTES:
1. All values are maximum guaranteed values.
2. All inputs switch between 0.2V (Low) and VDD – 0.2V (High).
3. fMAX = 1/tRC (all address inputs are cycling at fMAX); f = 0 means no address input lines are changing .
4. Typical values are measured at 3.3V, 25°C and with equal read and write cycles.

Timing Waveform of Read Cycle No. 2(1)
NOTES:
1. A write occurs during the overlap of a LOW CS, LOW BHE or BLE, and a LOW WE.
2. OE is continuously HIGH. If during a WE controlled write cycle OE is LOW, tWP must be greater than or equal to tWHZ + tDW to allow the I/O drivers to turn off and data to be placed
on the bus for the required tDW. If OE is HIGH during a WE controlled write cycle, this requirement does not apply and the minimum write pulse is as short as the specified tWP.
3. During this period, I/O pins are in the output state, and input signals must not be applied.
4. If the CS LOW or BHE and BLE LOW transition occurs simultaneously with or after the WE LOW transition, the outputs remain in a high-impedance state.
5. Transition is measured ±200mV from steady state.
Timing Waveform of Write Cycle No. 1 (WE Controlled Timing)(1,2,4)
NOTES:
1. WE is HIGH for Read Cycle.
2. Address must be valid prior to or coincident with the later of CS, BHE, or BLE transition LOW; otherwise tAA is the limiting parameter.
3. Transition is measured ±200mV from steady state.
