... RECALL Note r: 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 s: While there are 15 addresses on the STK14C88-3, only the lower 14 are used to control software modes. Note t: I/O state assumes G < Activation of nonvolatile cycles does not depend on state of G. ...

... STK14C88-3 The STK14C88-3 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 nonvolatile elements (the SRAM operation) or from nonvolatile elements to (the operation). In this mode RECALL tions are disabled ...

... READ WRITE operation in no way alters the data in the nonvolatile elements. The nonvolatile data can be recalled an unlimited number of times. AutoStore OPERATION The STK14C88-3 can be powered in one of three modes. During normal AutoStore operation, the STK14C88- 3 will draw current from V CCX connected to the V pin ...
