GALVANTECH, GVT71128D32 128K X 32 SYNCHRONOUS BURST SRAM SYNCHRONOUS BURST SRAM PIPELINED OUTPUT 128K x 32 SRAM +3.3V SUPPLY, PIPELINED, SINGLE CYCLE DESELECT, BURST COUNTER FEATURES GENERAL DESCRIPTION • • • • • The Galvantech Synchronous Burst SRAM family employs high-speed, low power CMOS designs using advanced triple-layer polysilicon, double-layer metal technology. Each memory cell consists of four transistors and two high valued resistors. The GVT71128D32 SRAM integrates 131,072x32 SRAM cells with advanced synchronous peripheral circuitry and a 2-bit counter for internal burst operation. All synchronous inputs are gated by registers controlled by a positive-edge-triggered clock input (CLK). The synchronous inputs include all addresses, all data inputs, address-pipelining chip enable (CE#), depth-expansion chip enables (CE2# and CE2), burst control inputs (ADSC#, ADSP#, and ADV#), write enables (BW1#, BW2#, BW3#, BW4#,and BWE#), and global write (GW#). Asynchronous inputs include the output enable (OE#) and burst mode control (MODE). The data outputs (Q), enabled by OE#, are also asynchronous. Addresses and chip enables are registered with either address status processor (ADSP#) or address status controller (ADSC#) input pins. Subsequent burst addresses can be internally generated as controlled by the burst advance pin (ADV#). Address, data inputs, and write controls are registered onchip to initiate self-timed WRITE cycle. WRITE cycles can be one to four bytes wide as controlled by the write control inputs. Individual byte write allows individual byte to be written. BW1# controls DQ1-DQ8. BW2# controls DQ9DQ16. BW3# controls DQ17-DQ24. BW4# controls DQ25DQ32. BW1#, BW2# BW3#, and BW4# can be active only with BWE# being LOW. GW# being LOW causes all bytes to be written. This device also incorporates pipelined enable circuit for easy depth expansion without penalizing system performance. The GVT71128D32 operates from a +3.3V power supply. All inputs and outputs are TTL-compatible. The device is ideally suited for 486, Pentium TM , 680x0, and PowerPCTM systems and for systems that are benefited from a wide synchronous data bus. • • • • • • • • • • • • • • Fast access times: 4.8, 5, 6, and 7ns Fast clock speed: 100, 83, and 66MHz Provide high performance 3-1-1-1 access rate Fast OE# access times: 5, 6, and 7ns Optimal for depth expansion (one cycle chip deselect to eliminate bus contention) Single +3.3V -5% and +10%power supply Support +2.5V I/O 5V tolerant inputs except I/O’s Clamp diodes to VSSQ at all outputs Common data inputs and data outputs BYTE WRITE ENABLE and GLOBAL WRITE control Three chip enables for depth expansion and address pipeline Address, control, input, and output pipeline registers Internally self-timed WRITE CYCLE Burst control pins (interleaved or linear burst sequence) Automatic power-down for portable applications High density, high speed packages Low capacitive bus loading High 30pF output drive capability at rated access time OPTIONS • • • MARKING Timing 4.8ns access/10ns cycle 5ns access/10ns cycle 6ns access/12ns cycle 7ns access/15ns cycle -4 -5 -6 -7 Packages 100-pin TQFP T Temperature Commercial Industrial None I (0°C to 70°C) (-40°C to 85°C) Galvantech, Inc. 3080 Oakmead Village Drive, Santa Clara, CA 95051 Tel (408) 566-0688 Fax (408) 566-0699 Web Site www.galvantech.com Rev. 11/9 9 Pentium is a trademark of Intel Corporation.

November 20, 1999 Rev. 11/9 9 ADSP # ADSC# X means “don’t care.” H means logic HIGH. L means logic LOW. WRITE# = L means [BWE# + BW1#*BW2#*BW3#*BW4#]*GW# equals LOW. WRITE# = H means [BWE# + BW1#*BW2#*BW3#*BW4#]*GW# equals HIGH. BW1# enables write to DQ1-DQ8. BW2# enables write to DQ9-DQ16. BW3# enables write to DQ17-DQ24. BW4# enables write to DQ25-DQ32. All inputs except OE# must meet setup and hold times around the rising edge (LOW to HIGH) of CLK. Suspending burst generates wait cycle. For a write operation following a read operation, OE# must be HIGH before the input data required setup time plus High-Z time for OE# and staying HIGH throughout the input data hold time. This device contains circuitry that will ensure the outputs will be in High-Z during power-up. ADSP# LOW along with chip being selected always initiates an READ cycle at the L-H edge of CLK. A WRITE cycle can be performed by setting WRITE# LOW for the CLK L-H edge of the subsequent wait cycle.
