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.ControlsAddresses, 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 ineither 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.Flow Through/Pipeline ReadsThe function of the Data Output register can be controlled by the user via the FT mode . 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 inPipeline mode, activating the rising-edge-triggered Data Output Register.SCD and DCD Pipelined ReadsThe GS8322V18/36/72 is a SCD (Single Cycle Deselect) and DCD (Dual Cycle Deselect) pipelined synchronous SRAM. DCD SRAMs pipeline disable commands to the same degree as read commands. SCD SRAMs pipeline deselect commands one stage less than read commands. SCD RAMs begin turning off their outputs immediately after the deselect command has been captured in the input registers. 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. The user may configure this SRAM for either mode of operation using the SCD mode input.Byte Write and Global WriteByte 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.FLXDrive™The ZQ pin allows selection between high drive strength (ZQ low) for multi-drop bus applications and normal drive strength (ZQ floating or high) point-to-point applications. See the Output Driver Characteristics chart for details.Parameter Synopsis-250-225-200-166-150-133UnitPipeline 3-1-1-1KQ t KQ (x72)tCycle 3.04.0 3.04.4 3.05.0 3.56.0 3.86.7 4.07.5ns ns Curr (x18)Curr (x36)Curr (x72)285350440265320410245295370220260320210240300185215265mA mA mA Flow Through 2-1-1-1t KQ tCycle 6.56.57.07.07.57.58.08.08.58.58.58.5ns ns Curr (x18)Curr (x36)Curr (x72)205235315195225295185210265175200255165190240155175230mA mA mAGS8322V18(B/E)/GS8322V36(B/E)/GS8322V72(C)209-Bump BGA—x72 Common I/O—Top View (Package C)1234567891011A DQ G DQ G A E2ADSP ADSC ADV E3A DQB DQ B AB DQ G DQ G BC BG NC BW A BB BF DQ B DQ B BC DQ G DQ G BH BD NC E1NC BE BA DQ B DQ B CD DQ G DQ G V SS NC NC G GW NC V SS DQ B DQ B DE DQP G DQP C V DDQ V DDQ V DD V DD V DD V DDQ V DDQ DQPF DQP B EF DQ C DQ C V SS V SS V SS ZQ V SS V SS V SS DQ F DQ F FG DQ C DQ C V DDQ V DDQ V DD MCH V DD V DDQ V DDQ DQ F DQ F GH DQ C DQ C V SS V SS V SS MCL V SS V SS V SS DQ F DQ F H J DQ C DQ C V DDQ V DDQ V DD MCL V DD V DDQ V DDQ DQ F DQ F J K NC NC CK NC V SS MCL V SS NC NC NC NC K L DQ H DQ H V DDQ V DDQ V DD FT V DD V DDQ V DDQ DQ A DQ A L M DQ H DQ H V SS V SS V SS MCL V SS V SS V SS DQ A DQ A M N DQ H DQ H V DDQ V DDQ V DD SCD V DD V DDQ V DDQ DQ A DQ A N P DQ H DQ H V SS V SS V SS ZZ V SS V SS V SS DQ A DQ A P R DQP D DQP H V DDQ V DDQ V DD V DD V DD V DDQ V DDQ DQP A DQP E R T DQ D DQ D V SS NC NC LBO NC NC V SS DQ E DQ E T U DQ D DQ D NC A A A A A A DQ E DQ E U V DQ D DQ D A A A A1A A A DQ E DQ E V W DQ D DQ D TMS TDI A A0A TDO TCK DQ E DQ E W11 x 19 Bump BGA—14 x 22 mm2 Body—1 mm Bump PitchGS8322V18(B/E)/GS8322V36(B/E)/GS8322V72(C)GS8322V72 209-Bump BGA Pin DescriptionSymbolTypeDescriptionA 0, A 1I Address field LSBs and Address Counter Preset Inputs.An IAddress InputsDQ A DQ B DQ C DQ D DQ E DQ F DQ G DQ H I/O Data Input and Output pinsB A , B B I Byte Write Enable for DQ A , DQ B I/Os;
