2.5 V or 3.3 V I/O  
interleave order 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  
• 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  
• JRoHS-compliant 100-lead TQFP package available  
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 GS8320E18/32/36AGT 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  
Applications  
The GS8320E18/32/36AGT is a 37,748,736-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.  
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.  
Controls  
Addresses, data I/Os, chip enables (E1, E2, E3), 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  
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.  
Core and Interface Voltages  
The GS8320E18/32/36AGT operates on a 3.3 V or 2.5 V  
power supply. All input are 3.3 V and 2.5 V compatible.  
Separate output power (V  
) pins are used to decouple  
DDQ  
output noise from the internal circuits and are 3.3 V and 2.5 V  
compatible.
