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.

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

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

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).

Instruction
Description
OPCODE
Forces contents of the boundary scan cells onto the device outputs(1).
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
0001
Loads the JTAG ID register (JIDR) with the vendor ID code and places
the register between TDI and TDO.
DEVICE_ID
HIGHZ
0010
0011
Places the bypass register (BYR) between TDI and TDO. Forces all
device output drivers to a High-Z state.

Automatically loaded into the instruction register whenever the TAP
controller passes through the CAPTURE-IR state. The lower two bits '01'
are mandated by the IEEE std. 1149.1 specification.
VALIDATE

BYPASS
Same as above.

The BYPASS instruction is used to truncate the boundary scan register
as a single bit in length.
