Description  
A0-A17  
Address Inputs  
I
N/A  
Synchronous Address inputs. The address register is triggered by a combi-nation of the rising edge of CLK  
and ADSC Low or ADSP Low and CE Low.  
Address Status  
(Cache Controller)  
I
I
I
LOW  
LOW  
LOW  
Synchronous Address Status from Cache Controller. ADSC is an active LOW input that is used to load the  
ADSC  
ADSP  
ADV  
address registers with new addresses.  
Address Status  
(Processor)  
Synchronous Address Status from Processor. ADSP is an active LOW input that is used to load the address  
registers with new addresses. ADSP is gated by CE.  
Burst Address  
Advance  
Synchronous Address Advance. ADV is an active LOW input that is used to advance the internal burst counter,  
controlling burst access after the initial address is loaded. When the input is HIGH the burst counter is not  
incremented; that is, there is no address advance.  
Byte Write Enable  
I
I
LOW  
LOW  
Synchronous byte write enable gates the byte write inputs BW  
then BWx inputs are passed to the next stage in the circuit. If BWE is HIGH then the byte write inputs are  
blocked and only GW can initiate a write cycle.

Global Write  
Enable  
Synchronous global write enable. This input will write all four 9-bit data bytes when LOW on the rising edge of  
CLK. GW supersedes individual byte write enables.  
I/O  
I/OP1-I/OP4  
0

Data Input/Output  
I/O  
I
N/A  
Synchronous data input/output (I/O) pins. The data input path is registered, triggered by the rising edge of  
CLK. The data output path is flow-through (no output register).  
Linear Burst Order  
LOW  
Asynchronous burst order selection input. When LBO is HIGH, the inter-leaved burst sequence is selected.  
When LBO is LOW the Linear burst sequence is selected. LBO is a static input and must not change state  
while the device is operating.  
LBO  
Output Enable  
I
LOW  
Asynchronous output enable. When OE is LOW the data output drivers are enabled on the I/O pins if the chip  
is also selected. When OE is HIGH the I/O pins are in a high-impedance state.

N/A  
N/A  
Gives input command for TAP controller. Sampled on rising edge of TDK. This pin has an internal pullup.  
Serial input of registers placed between TDI and TDO. Sampled on rising edge of TCK. This pin has an  
internal pullup.  
Clock input of TAP controller. Each TAP event is clocked. Test inputs are captured on rising edge of TCK,  
while test outputs are driven from the falling edge of TCK. This pin has an internal pullup.  
TCK

N/A  
N/A  
Serial output of registers placed between TDI and TDO. This output is active depending on the state of the  
TAP controller.

Optional Asynchronous JTAG reset. Can be used to reset the TAP controller, but not required. JTAG reset  
occurs automatically at power up and also resets using TMS and TCK per IEEE 1149.1. If not used TRST can  
be left floating. This pin has an internal pullup. Only available in BGA package.

Asynchronous sleep mode input. ZZ HIGH will gate the CLK internally and power down the IDT71V3577/79 to  
its lowest power consumption level. Data retention is guaranteed in Sleep Mode.This pin has an internal pull  
down.
