STK14C88-N25M

The STK14C88-N25M is one of the STK14C88 series. The Simtek STK14C88 is a fast static RAM with a nonvolatile element incorporated in each static memory cell. The SRAM can be read and written an unlimited number of times, while independent, nonvolatile data resides in the nonvolatile elements. Data transfers from the SRAM to the nonvolatile elements(the STORE operation) can take place automatically on power down. A 68F or larger capacitor
tied from VCAP to ground guarantees the STORE operation, regardless of power-down slew rate or loss of power from "hot swapping". Transfers from the nonvolatile elements to the SRAM (the RECALL operation) take place automatically on restoration of power. Initiation of STORE and RECALL cycles can also be software controlled by entering specific read sequences. A hardware STORE may be initiated with the HSB pin.

Features of the STK14C88-N25M are:(1)25ns, 35ns and 45ns Access Times; (2)"Hands-off"Automatic STORE with External 68F Capacitor on Power Down; (3)STORE to nonvolatile elements Initiated by Hardware, Software or AutoStore RECALL to SRAM Initiated by Software or Power Restore; (4)10mA Typical ICC at 200ns Cycle Time; (5)Unlimited READ, WRITE and RECALL Cycles; (6)1,000,000 STORE Cycles to nonvolatile elements(Commercial/Industrial); (7)100-Year Data Retention in nonvolatile elements(Commercial/Industrial); (8)Single 5V + 10% Operation; (9)Commercial, Industrial and Military Temperatures; (10)32-Pin SOIC, DIP and LCC Packages.

The absolute maximum ratings of the STK14C88-N25M can be summarized as:((1)Voltage on Input Relative to Ground: 0.5V to 7.0V; (2)Voltage on Input Relative to VSS:0.6V to (VCC + 0.5V); (3)Voltage on DQ0-7 or HSB :0.5V to (VCC + 0.5V); (4)Temperature under Bias:55°C to 125°C; (5)Storage Temperature:65°C to 150°C; (6)Power Dissipation:1W; (7)DC Output Current (1 output at a time, 1s duration): 15mA.If you want to know more information such as the electrical characteristics about the BF904, please download the datasheet in www.seekic.com or www.chinaicmart.com.
