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

The Cypress STK14C88 is a 256 Kb fast static RAM with a nonvolatile Quantum Trap storage element included with each memory cell.
• Automatic Nonvolatile STORE on Power Loss

The SRAM provides the fast access and cycle times, ease of

use, and unlimited read and write endurance of a normal SRAM.

Data automatically transfers 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.

Input I/O Input

Address The 15 address inputs select one of 32,768 bytes in the nvSRAM array. Data Bi-directional 8-bit data bus for accessing the nvSRAM. Chip Enable The active low E input selects the device.

Input

Write Enable The active low W enables data on the DQ pins to be written to the address
c location latched by the falling edge of E.

Input

Output Enable The active low G input enables the data output buffers during read cycles.

RDe-asserting G high caused the DQ pins to tristate.
t VCC No HSB

Power Supply Power 5.0V,

Hardware Store Busy When low this output indicates a Store is in progress. When pulled
low external to the chip, it initiates a nonvolatile STORE operation. A weak pull up resistor
