2.5 V or 3.3 V I/O  
with the Linear Burst Order (LBO) input. The Burst function need not  
be used. New addresses can be loaded on every cycle with no  
degradation of chip performance.  
Features  
• FT pin for user-configurable flow through or pipeline  
operation  
• Dual Cycle Deselect (DCD) operation  
• IEEE 1149.1 JTAG-compatible Boundary Scan  
• 2.5 V or 3.3 V +10%/–10% core power supply  
• 2.5 V or 3.3 V I/O supply  
• LBO pin for Linear or Interleaved Burst mode  
• Internal input resistors on mode pins allow floating mode pins  
• Default to Interleaved Pipeline mode  
• Byte Write (BW) and/or Global Write (GW) operation  
• Internal self-timed write cycle  
• Automatic power-down for portable applications  
• JEDEC-standard 100-lead TQFP and 165-bump BGA  
packages  
Flow Through/Pipeline Reads  
The function of the Data Output register can be controlled by the user  
via the FT mode pin (Pin 14). Holding the FT mode pin low places the  
RAM in Flow Through mode, causing output data to bypass the Data  
Output Register. Holding FT high places the RAM in Pipeline mode,  
activating the rising-edge-triggered Data Output Register.  
DCD Pipelined Reads  
The GS8161E18(T/D)/GS8161E32(D)/GS8161E36(T/D) is a DCD  
(Dual Cycle Deselect) pipelined synchronous SRAM. SCD (Single  
Cycle Deselect) versions are also available. DCD SRAMs pipeline  
disable commands to the same degree as read commands. DCD  
RAMs hold the deselect command for one full cycle and then begin  
turning off their outputs just after the second rising edge of clock.  
Functional Description  
Byte Write and Global Write  
Byte write operation is performed by using Byte Write enable (BW)  
input combined with one or more individual byte write signals (Bx).  
In addition, Global Write (GW) is available for writing all bytes at one  
time, regardless of the Byte Write control inputs.  
Applications  
The GS8161E18(T/D)/GS8161E32(D)/GS8161E36(T/D) is a  
18,874,368-bit high performance synchronous SRAM with a 2-bit  
burst address counter. Although of a type originally developed for  
Level 2 Cache applications supporting high performance CPUs, the  
device now finds application in synchronous SRAM applications,  
ranging from DSP main store to networking chip set support.  
Sleep Mode  
Low power (Sleep mode) is attained through the assertion (High) of  
the ZZ signal, or by stopping the clock (CK). Memory data is retained  
during Sleep mode.  
Controls  
Addresses, data I/Os, chip enable (E1), address burst control inputs  
(ADSP, ADSC, ADV) and write control inputs (Bx, BW, GW) are  
synchronous and are controlled by a positive-edge-triggered clock  
input (CK). Output enable (G) and power down control (ZZ) are  
asynchronous inputs. Burst cycles can be initiated with either ADSP  
or ADSC inputs. In Burst mode, subsequent burst addresses are  
generated internally and are controlled by ADV. The burst address  
counter may be configured to count in either linear or interleave order  
Core and Interface Voltages  
The GS8161E18(T/D)/GS8161E32(D)/GS8161E36(T/D) operates on  
a 2.5 V or 3.3 V power supply. All input are 3.3 V and 2.5 V  
compatible. Separate output power (VDDQ) pins are used to decouple  
output noise from the internal circuits and are 3.3 V and 2.5 V  
compatible.
