... STK12C68 The STK12C68 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 STK12C68 can be powered in one of three modes. During normal AutoStore™ STK12C68 will draw current from V capacitor connected to the V ...
