... Note k: 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 l: While there are 17 addresses on the STK16CA8, only the lower 16 are used to control software modes. Note m: I/O state depends on the state of G. The I/O table shown assumes G low. ...

... STK16CA8 The STK16CA8 has two separate modes of opera- tion: mode and nonvolatile mode. In SRAM mode, the memory operates as a standard fast static . In nonvolatile mode, data is transferred RAM from to the nonvolatile elements (the SRAM operation) or from the nonvolatile elements to (the operation). In this mode RECALL tions are disabled ...

... Figure 4 shows the same relationship for cycles. If the chip enable duty cycle is less WRITE than 100%, only standby current is drawn when the chip is disabled. The overall average current drawn s dur- SRAM WRITE by the STK16CA8 depends on the following items: < all CCX SWITCH 1) CMOS SRAM chip enable ...
