STK14D88
32Kx8 AutoStore nvSRAM
• 25, 35, 45 ns Read Access and R/W Cycle Time
• Unlimited Read/Write Endurance

The Cypress STK14D88 is a 256Kb fast static RAM with a nonvolatile Quantum Trap storage element included with each memory cell.
• Automatic Nonvolatile STORE on Power Loss

The SRAM provides fast access and cycle times, ease of use,
• Nonvolatile STORE Under Hardware or Software Control
s
• Automatic RECALL to SRAM on Power Up n
• Unlimited RECALL Cycles ig
• 200K STORE Cycles es
• 20-Year Nonvolatile Data Retention D
• Single 3.0V +20%, -10% Power Supply
• Commercial, Industrial Temperatures
w
• Small Footprint SOIC and SSOP Packages RoHS-Compliant
and unlimited read and write endurance of a normal SRAM.

Data transfers automatically to the nonvolatile storage cells when power loss is detected the STORE operation . On power up, data is automatically restored to the SRAM the RECALL operation . Both STORE and RECALL operations are also available under software control.

The Cypress nvSRAM is the first monolithic nonvolatile memory to offer unlimited writes and reads. It is the highest performance, most reliable nonvolatile memory available.
