The SRAM can be read and written an unlimited number of times, while independent nonvolatile data resides in Nonvolatile Elements. Data transfers from the SRAM to the Nonvolatile Elements (the STORE operation) can take place automatically on power down. An internal capacitor guarantees the STORE operation regardless of power-down slew rate. Transfers from the Nonvolatile Elements to the SRAM (the RECALL operation) take place automati- cally on restoration of power. Initiation of STORE and RECALL cycles can also be controlled by entering control sequences on the SRAM inputs. The STK16C88-3 is pin-compatible with 32k x 8 SRAMs and battery-backed SRAMs, allowing direct substitu- tion while providing superior performance. The STK14C88-3, which uses an external capacitor, is also available.
