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.

FEATUREs
• Fast match times: 3.5, 3.8, 4.0 and 4.5 ns
• Fast clock speed: 166, 150, 133, and 100 MHz
• Fast OE access times: 3.5, 3.8, 4.0 and 5.0 ns
• Pipelined data comparator
• Data input register load control by DEN
• Optimal for depth expansion (one cycle chip deselect to eliminate bus contention)
• 3.3V –5% and +10% core power supply
• 2.5V or 3.3V I/O supply
• 5V tolerant inputs except I/Os
• Clamp diodes to VSS at all inputs and outputs
• Common data inputs and data outputs
• JTAG boundary scan
• Byte Write Enable and Global Write control
• Three chip enables for depth expansion and address pipeline
• Address, data, and control registers
• Internally self-timed Write Cycle
• Burst control pins (interleaved or linear burst sequence)
• Automatic power-down for portable applications
• Low-profile JEDEC standard 100-pin TQFP package
