Board sites for flow through Burst RAMS should be designed with VSS connected to the FT pin location to ensure the broadest access to multiple vendor sources. Boards designed with FT pin pads tied low may be stuffed with GSI’s pipeline/flow through-configurable Burst RAMs or any vendor’s flow through or configurable Burst SRAM. Boards designed with the FT pin location tied high or floating must employ a non-configurable flow through Burst RAM, like this RAM, to achieve flow through functionality. 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 GS880F18/32/36BT-xxxV operates on a 1.8 V or 2.5 V power supply. All input are 2.5 V and 1.8 V compatible. Separate output power (VDDQ) pins are used to decouple output noise from the internal circuits and are 2.5 V and 1.8 V compatible. Functional Description Applications The GS880F18/32/36BT-xxxV is a 9,437,184-bit (8,388,608bit for x32 version) 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. 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 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.

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 ZZ recovery 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.
