... Transfers from the EEPROM place automatically on restoration of power. Initia- tion of trolled by entering control sequences on the inputs. The STK16C88 is pin-compatible with 32k x 8 SRAM substitution while enhancing performance. The STK14C88, which uses an external capacitor, and the STK15C88, which uses charge stored in system capacitance, are alternatives for systems needing AutoStorePlus™ ...
