CY7C1363A/GVT71512B18  
256K x 36/512K x 18 Synchronous Burst Flowthrough SRAM  
and a 2-bit counter for internal burst operation. All synchro-  
Features  
nous inputs are gated by registers controlled by a positive-  
edge-triggered Clock Input (CLK). The synchronous inputs in-  
clude 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  
(BWa, BWb, BWc, BWd, and BWE), and Global Write (GW).  
However, the CE2 chip enable input is only available for TA(GV-  
TI)/A(CY) package version.  
• Fast access times: 6.0, 6.5, 7.0, and 8.0 ns  
• Fast clock speed: 150, 133, 117, and 100 MHz  
• 1 ns set-up time and hold time  
• Fast OE access times: 3.5 ns and 4.0 ns  
• 3.3V –5% and +10% power supply  
• 3.3V or 2.5V I/O supply  
• 5V tolerant inputs except I/Os  
Asynchronous inputs include the Output Enable (OE) and  
burst mode control (MODE). The data outputs (Q), enabled by  
OE, are also asynchronous.  
• Clamp diodes to VSS at all inputs and outputs  
• Common data inputs and data outputs  
• Byte Write Enable and Global Write control  
• Multiple chip enables for depth expansion:  
three chip enables for TA(GVTI)/A(CY) package version  
and two chip enables for B(GVTI)/BG(CY) and  
T(GVTI)/AJ(CY) package versions  
• Address pipeline capability  
• Address, data and control registers  
• Internally self-timed Write Cycle  
• Burst control pins (interleaved or linear burst se-  
quence)  
• Automatic power-down for portable applications  
• JTAG boundary scan for B and T package version  
• Low profile 119-bump, 14-mm x 22-mm PBGA (Ball Grid  
Array) and 100-pin TQFP packages  
Addresses and chip enables are registered with either Ad-  
dress Status Processor (ADSP) or Address Status Controller  
(ADSC) input pins. Subsequent burst addresses can be inter-  
nally generated as controlled by the Burst Advance pin (ADV).  
Address, data inputs, and write controls are registered on-chip  
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. BWa  
controls DQa. BWb controls DQb. BWc controls DQc. BWd  
controls DQd. BWa, BWb, BWc, and BWd can be active only  
with BWE being LOW. GW being LOW causes all bytes to be  
written. The x18 version only has 18 data inputs/outputs (DQa  
and DQb) along with BWa and BWb (no BWc, BWd, DQc, and  
DQd).  
For the B(GVTI)/BG(CY) and T(GVTI)/AJ(CY) package ver-  
sions, four pins are used to implement JTAG test capabilities:  
Test Mode Select (TMS), Test Data-In (TDI), Test Clock (TCK),  
and Test Data-Out (TDO). The JTAG circuitry is used to serially  
shift data to and from the device. JTAG inputs use  
LVTTL/LVCMOS levels to shift data during this testing mode of  
operation. The TA package version does not offer the JTAG  
capability.  
Functional Description  
The Cypress 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 GVT71256B36/CY7C1361A and GVT71512B18/  
CY7C1363A SRAMs integrate 262,144x36 and 524,288x18  
SRAM cells with advanced synchronous peripheral circuitry  
The GVT71256B36 and GVT71512B18 operate from a +3.3V  
power supply. All inputs and outputs are LVTTL compatible.
