... Note q: The six consecutive addresses must be in the order listed. W must be high during all six consecutive cycles to enable a nonvolatile cycle. Note r: While there are 19 addresses on the STK14EC8, only the lower 16 are used to control software modes Note s: I/O state depends on the state of G. The I/O table shown assumes G low Document Control #ML0060 Rev 1 ...

... Preliminary nvSRAM The STK14EC8 nvSRAM is made up of two func- tional components paired in the same physical cell. These are the SRAM memory cell and a nonvolatile QuantumTrap cell. The SRAM memory cell operates like a standard fast static RAM. Data in the SRAM can be transferred to the nonvolatile cell (the STORE operation), or from the nonvolatile cell to SRAM (the RECALL operation) ...

... HSB is driven low or when V below V are given time to complete before the switch STORE operation is initiated. After AUTOSTORE or HSB goes low, the STK14EC8 will continue to allow SRAM operations for t .

... STORE and WRITE operations. The low-volt- age condition is detected when V If the STK14EC8 WRITE mode (both E and W low) at power-up, after a RECALL, or after a STORE, the WRITE will be inhibited until a negative transition detected. This protects against inadvertent writes during power up or brown out conditions ...
