Preliminary GS8320V18/32/36T-250/225/200/166/150/133 100-Pin TQFP Commercial Temp Industrial Temp Features • FT pin for user-configurable flow through or pipeline operation • Single Cycle Deselect (SCD) operation • 1.8 V +10%/–10% core power supply • 1.8 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 • 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 2M x 18, 1M x 32, 1M x 36 36Mb Sync Burst SRAMs 250 MHz–133 MHz 1.8 V VDD 1.8 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. 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 risingedge-triggered Data Output Register. Byte Write and Global Write 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. 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. Core and Interface Voltages The GS8320V18/32/36T operates on a 1.8 V power supply. All input are 1.8 V compatible. Separate output power (VDDQ) pins are used to decouple output noise from the internal circuits and are 1.8 V compatible. Functional Description Applications The GS8320V18/32/36T 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. 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.

G is an asynchronous input. G can be driven high at any time to disable active output drivers. G low can only enable active drivers (shown as “Q” in the Truth Table above). 5. All input combinations shown above are tested and supported. Input combinations shown in gray boxes need not be used to accomplish basic synchronous or synchronous burst operations and may be avoided for simplicity. 6. Tying ADSP high and ADSC low allows simple non-burst synchronous operations. See BOLD items above. 7. Tying ADSP high and ADV low while using ADSC to load new addresses allows simple burst operations. See ITALIC items above.

Dummy Read cycles increment the address counter just like normal read cycles. 3. Transitions shown in gray tone assume G has been pulsed high long enough to turn the RAM’s drivers off and for incoming data to meet Data Input Set Up Time.

Preliminary GS8320V18/32/36T-250/225/200/166/150/133 Sleep Mode During normal operation, ZZ must be pulled low, either by the user or by its internal pull down resistor. When ZZ is pulled high, the SRAM will enter a Power Sleep mode after 2 cycles. At this time, internal state of the SRAM is preserved. When ZZ returns to low, the SRAM operates normally after 2 cycles of wake up time. Sleep mode is a low current, power-down mode in which the device is deselected and current is reduced to ISB2. The duration of Sleep mode is dictated by the length of time the ZZ is in a High state. After entering Sleep mode, all inputs except ZZ become disabled and all outputs go to High-Z The ZZ pin is an asynchronous, active high input that causes the device to enter Sleep mode. When the ZZ pin is driven high, ISB2 is guaranteed after the time tZZI is met. Because ZZ is an asynchronous input, pending operations or operations in progress may not be properly completed if ZZ is asserted. Therefore, Sleep mode must not be initiated until valid pending operations are completed. Similarly, when exiting Sleep mode during tZZR, only a Deselect or Read commands may be applied while the SRAM is recovering from Sleep mode.
