rail for proper operation. Asynchronous inputs include the  
Features  
Sleep mode enable (ZZ) and Output Enable. Output Enable can  
be used to override the synchronous control of the output  
drivers and turn the RAM's output drivers off at any time.  
Write cycles are internally self-timed and initiated by the rising  
edge of the clock input. This feature eliminates complex off-  
chip write pulse generation required by asynchronous SRAMs  
and simplifies input signal timing.  
• NBT (No Bus Turn Around) functionality allows zero wait  
read-write-read bus utilization; Fully pin-compatible with  
both pipelined and flow through NtRAM™, NoBL™ and  
ZBT™ SRAMs  
• 1.8 V +10%/–10% core power supply  
• 1.8 V I/O supply  
• User-configurable Pipeline and Flow Through mode  
• LBO pin for Linear or Interleave Burst mode  
• Pin compatible with 2M, 4M, and 18M devices  
• Byte write operation (9-bit Bytes)  
• 3 chip enable signals for easy depth expansion  
• ZZ Pin for automatic power-down  
• JEDEC-standard 100-lead TQFP package  
• Pb-Free 100-lead TQFP package available  
The GS880ZV18/36BT may be configured by the user to  
operate in Pipeline or Flow Through mode. Operating as a  
pipelined synchronous device, meaning that in addition to the  
rising edge triggered registers that capture input signals, the  
device incorporates a rising-edge-triggered output register. For  
read cycles, pipelined SRAM output data is temporarily stored  
by the edge triggered output register during the access cycle  
and then released to the output drivers at the next rising edge of  
clock.  
Functional Description  
The GS880ZV18/36BT is a 9Mbit Synchronous Static SRAM.  
GSI's NBT SRAMs, like ZBT, NtRAM, NoBL or other  
pipelined read/double late write or flow through read/single  
late write SRAMs, allow utilization of all available bus  
bandwidth by eliminating the need to insert deselect cycles  
when the device is switched from read to write cycles.  
The GS880ZV18/36BT is implemented with GSI's high  
performance CMOS technology and is available in a JEDEC-  
Standard 100-pin TQFP package.  
Because it is a synchronous device, address, data inputs, and  
read/ write control inputs are captured on the rising edge of the  
input clock. Burst order control (LBO) must be tied to a power
