GS8161ZxxD(GT/D)-xxxV 333 MHz150 MHz 100-Pin TQFP & 165-Bump BGA 18Mb Pipelined and Flow Through 1.8 V or 2.5 V V DD Commercial Temp 1.8 V or 2.5 V I/O Industrial Temp Synchronous NBT SRAM Because it is a synchronous device, address, data inputs, and Features read/ write control inputs are captured on the rising edge of the User-configurable Pipeline and Flow Through mode input clock. Burst order control (LBO) must be tied to a power NBT (No Bus Turn Around) functionality allows zero wait rail for proper operation. Asynchronous inputs include the read-write-read bus utilization Sleep mode enable, ZZ and Output Enable. Output Enable can Fully pin-compatible with both pipelined and flow through be used to override the synchronous control of the output NtRAM, NoBL and ZBT SRAMs drivers and turn the RAM s output drivers off at any time. IEEE 1149.1 JTAG-compatible Boundary Scan Write cycles are internally self-timed and initiated by the rising 1.8 V or 2.5 V core power supply edge of the clock input. This feature eliminates complex off- 1.8 V or 2.5 V I/O supply chip write pulse generation required by asynchronous SRAMs LBO pin for Linear or Interleave Burst mode and simplifies input signal timing. Pin-compatible with 2Mb, 4Mb, 8Mb, 36Mb, 72Mb and 144Mb devices The GS8161ZxxD(GT/D)-xxxV may be configured by the user Byte write operation (9-bit Bytes) to operate in Pipeline or Flow Through mode. Operating as a 3 chip enable signals for easy depth expansion pipelined synchronous device, in addition to the rising-edge- ZZ pin for automatic power-down triggered registers that capture input signals, the device JEDEC-standard 165-bump BGA package incorporates a rising-edge-triggered output register. For read RoHS-compliant 100-pin TQFP and BGA packages available cycles, pipelined SRAM output data is temporarily stored by the edge triggered output register during the access cycle and Functional Description then released to the output drivers at the next rising edge of The GS8161ZxxD(GT/D)-xxxV is an 18Mbit Synchronous clock. Static SRAM. GSI s NBT SRAMs, like ZBT, NtRAM, NoBL or other pipelined read/double late write or flow through read/ The GS8161ZxxD(GT/D)-xxxV is implemented with GSI s single late write SRAMs, allow utilization of all available bus high performance CMOS technology and is available in bandwidth by eliminating the need to insert deselect cycles JEDEC-standard 165-bump FP-BGA package. when the device is switched from read to write cycles.
