Preliminary  
GS832018/32/36T-250/225/200/166/150/133  
250 MHz–133 MHz  
100-Pin TQFP  
Commercial Temp  
Industrial Temp  
2M x 18, 1M x 32, 1M x 36  
36Mb Sync Burst SRAMs  
2.5 V or 3.3 V V  
DD  
2.5 V or 3.3 V I/O  
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 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  
• Single Cycle Deselect (SCD) 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  
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.  
• 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 package  
• Pb-Free 100-lead TQFP package available  
Byte Write and Global Write  
Functional Description  
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 GS832018/32/36T 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.  
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 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  
Core and Interface Voltages  
The GS832018/32/36T 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 (V  
) pins are used to decouple output noise  
DDQ  
from the internal circuits and are 3.3 V and 2.5 V compatible.
