N/A Synchronous Address inputs. The address register is triggered by a combination of the rising edge of CLK,  
ADV/LD low, CEN low, and true chip enables.  
ADV/LD  
N/A ADV/LD is a synchronous input that is used to load the internal registers with new address and control  
when it is sampled low at the rising edge of clock with the chip selected. When ADV/LD is low with the  
chip deselected, any burst in progress is terminated. When ADV/LD is sampled high then the internal burst  
counter is advanced for any burst that was in progress. The external addresses are ignored when ADV/LD  
is sampled high.  
R/W  
Read / Write  
Clock Enable  
I
I
N/A R/W signal is a synchronous input that identifies whether the current load cycle initiated is a Read or Write  
access to the memory array. The data bus activity for the current cycle takes place one clock cycle later.  
LOW Synchronous Clock Enable Input. When CEN is sampled high, all other synchronous inputs, including  
clock are ignored and outputs remain unchanged. The effect of CEN sampled high on the device outputs  
is as if the low to high clock transition did not occur. For normal operation, CEN must be sampled low at  
rising edge of clock.

cycles (When R/W and ADV/LD are sampled low) the appropriate byte write signal (BW

ignored when R/W is sampled high. The appropriate byte(s) of data are written into the device one cycle  
later. BW

N/A This is the clock input to the IDT71T75902. Except for OE, all timing references for the device are made  
with respect to the rising edge of CLK.

-I/O31 Data Input/Output I/O  
N/A Data input/output (I/O) pins. The data input path is registered, triggered by the rising edge of CLK. The

I
I
LOW Burst order selection input. When LBO is high the Interleaved burst sequence is selected. When LBO is  
low the Linear burst sequence is selected. LBO is a static input, and it must not change during device  
operation.  
LBO  
LOW Asynchronous output enable. OE must be low to read data from the IDT71T75902. When OE is HIGH the  
I/O pins are in a high-impedance state. OE does not need to be actively controlled for read and write  
cycles. In normal operation, OE can be tied low.

NOTES:  
1. L = VIL, H = VIH, X = Don’t Care.  
2. When ADV/LD signal is sampled high, the internal burst counter is incremented. The R/W signal is ignored when the counter is advanced. Therefore the nature of  
the burst cycle (Read or Write) is determined by the status of the R/W signal when the first address is loaded at the beginning of the burst cycle.  
3. Deselect cycle is initiated when either (CE1, or CE2 is sampled high or CE2 is sampled low) and ADV/LD is sampled low at rising edge of clock. The data bus will  
tri-state one cycle after deselect is initiated.  
4. When CEN is sampled high at the rising edge of clock, that clock edge is blocked from propagating through the part. The state of all the internal registers and the  
I/Osremainsunchanged.  
5. To select the chip requires CE1 = L, CE2 = L and CE2 = H on these chip enable pins. The chip is deselected if any one of the chip enables is false.  
6. Device Outputs are ensured to be in High-Z during device power-up.  
7. Q - data read from the device, D - data written to the device.

NOTES:  
1. Measured as HIGH above 0.6VDDQ and LOW below 0.4VDDQ.  
2. Transition is measured ±200mV from steady-state.  
3. These parameters are guaranteed with the AC load (Figure 1) by device characterization. They are not production tested.  
4. To avoid bus contention, the output buffers are designed such that tCHZ (device turn-off) is about 1ns faster than tCLZ (device turn-on) at a given temperature and voltage.  
The specs as shown do not imply bus contention because tCLZ is a Min. parameter that is worse case at totally different test conditions (0 deg. C, 2.625V) than tCHZ,  
which is a Max. parameter (worse case at 70 deg. C, 2.375V).

Places the boundary scan register (BSR) between TDI and TDO.  
EXTEST  
0000  
Places the boundary scan register (BSR) between TDI and TDO.  
SAMPLE allows data from device inputs(2) and outputs(1) to be captured  
in the boundary scan cells and shifted serially through TDO. PRELOAD  
allows data to be input serially into the boundary scan cells via the TDI.  
SAMPLE/PRELOAD
