Functional Description
Applications GS864418/36E-xxxV 75,497,472-bit high performance synchronous SRAM with 2-bit burst address counter. Although type originally developed Level Cache applications supporting high performance CPUs, device finds application synchronous SRAM applications, ranging from main store networking chip support. Controls Addresses, data I/Os, chip enable (E1), address burst control inputs (ADSP, ADSC, ADV), write control inputs (Bx, synchronous controlled positive-edgetriggered clock input (CK). Output enable power down control (ZZ) asynchronous inputs. Burst cycles initiated with either ADSP ADSC inputs. Burst mode, subsequent burst addresses generated internally controlled ADV. burst address counter configured count either linear interleave order with Linear Burst Order (LBO) input. Burst function need used. addresses loaded every cycle with degradation chip performance. Flow Through/Pipeline Reads function Data Output register controlled user mode Holding mode places Flow Through mode, causing output data bypass
Pipelined Reads GS864418/36E-xxxV (Single Cycle Deselect) (Dual Cycle Deselect) pipelined synchronous SRAM. SRAMs pipeline disable commands same degree read commands. SRAMs pipeline deselect commands stage less than read commands. RAMs begin turning their outputs immediately after deselect command been captured input registers. RAMs hold deselect command full cycle then begin turning their outputs just after second rising edge clock. user configure this SRAM either mode operation using mode input. Byte Write Global Write Byte write operation performed using Byte Write enable (BW) input combined with more individual byte write signals (Bx). addition, Global Write (GW) available writing bytes time, regardless Byte Write control inputs. FLXDriveThe allows selection between high drive strength low) multi-drop applications normal drive strength floating high) point-to-point applications. Output Driver Characteristics chart details. Sleep Mode power (Sleep mode) attained through assertion (High) signal, stopping clock (CK). Memory data retained during Sleep mode. Core Interface Voltages GS864418/36E-xxxV operates power supply. inputs compatible. Separate output power (VDDQ) pins used decouple output noise from internal circuits compatible.

Sleep Mode
During normal operation, must pulled low, either user internal pull down resistor. When pulled high, SRAM will enter Power Sleep mode after cycles. this time, internal state SRAM preserved. When returns low, SRAM operates normally after recovery time. Sleep mode current, power-down mode which device deselected current reduced ISB2. duration Sleep mode dictated length time High state. After entering Sleep mode, inputs except become disabled outputs High-Z asynchronous, active high input that causes device enter Sleep mode. When driven high, ISB2 guaranteed after time tZZI met. Because asynchronous input, pending operations operations progress properly completed asserted. Therefore, Sleep mode must initiated until valid pending operations completed. Similarly, when exiting Sleep mode during tZZR, only Deselect Read commands applied while SRAM recovering from Sleep mode.

Application Tips
Single Dual Cycle Deselect devices (like this one) force "dummy read cycles" (read cycles that launched normally, that ended with output drivers inactive) fully synchronous environment. Dummy read cycles waste performance, their usually assures there will contention transitions from reads writes between banks RAMs. SRAMs waste bandwidth dummy cycles logically simpler manage multiple bank application (wait states need inserted bank address boundary crossings), greater care must exercised avoid excessive contention.
JTAG Port Operation
Overview JTAG Port this operates manner that compliant with IEEE Standard 1149.1-1990, serial boundary scan interface standard (commonly referred JTAG). JTAG Port input interface levels scale with VDD. JTAG output drivers powered VDDQ. Disabling JTAG Port possible this device without utilizing JTAG port. port reset power-up will remain inactive unless clocked. TCK, TDI, designed with internal pull-up circuits.To assure normal operation with JTAG Port unused, TCK, TDI, left floating tied either VSS. should left unconnected.

SAMPLE/PRELOAD SAMPLE/PRELOAD Standard 1149.1 mandatory public instruction. When SAMPLE PRELOAD instruction loaded Instruction Register, moving controller into Capture-DR state loads data RAMs input buffers into Boundary Scan Register. Boundary Scan Register locations associated with input pin, loaded with default state identified Boundary Scan Chain table this section datasheet. Because clock independent from Clock (TCK) possible attempt capture ring contents while input buffers transition (i.e. metastable state). Although allowing sample metastable inputs will harm device, repeatable results cannot expected. input signals must stabilized long enough meet TAPs input data capture set-up plus hold time (tTS plus tTH). RAMs clock inputs need paused other operation except capturing ring contents into Boundary Scan Register. Moving controller Shift-DR state then places boundary scan register between pins. EXTEST EXTEST IEEE 1149.1 mandatory public instruction. executed whenever instruction register loaded with logic EXTEST command does block override RAM's input pins; therefore, RAM's internal state still determined input pins. Typically, Boundary Scan Register loaded with desired pattern data with SAMPLE/PRELOAD command. Then EXTEST command used output Boundary Scan Register's contents, parallel, RAM's data output drivers falling edge when controller Update-IR state. Alternately, Boundary Scan Register loaded parallel using EXTEST command.
