STK16C88  
32K x 8 AutoStorePlus™ nvSRAM  
QuantumTrap™ CMOS  
Nonvolatile Static RAM  
FEATURES  
DESCRIPTION  
• Transparent Data Save on Power Down  
• Internal Capacitor Guarantees AutoStore™  
Regardless of Power-Down Slew Rate  
• Nonvolatile Storage without Battery Problems  
• Directly Replaces 32K x 8 Static RAM, Battery-  
Backed RAM or EEPROM  
• 20ns, 25ns, 35ns and 45ns Access Times  
• STORE to EEPROM Initiated by Software or  
AutoStorePlus™ on Power Down  
• No Data Loss from Undershoot  
• RECALL to SRAM Initiated by Software or  
Power Restore  
• 10mA Typical ICC at 200ns Cycle Time  
• Unlimited READ, WRITE and RECALL Cycles  
• 1,000,000 STORE Cycles to EEPROM  
• 100-Year Data Retention over Full Industrial  
Temperature Range  
The STK16C88 is a fast SRAM with a nonvolatile  
EEPROM element incorporated in each static mem-  
ory cell. The SRAM can be read and written an  
unlimited number of times, while independent non-  
volatile data resides in EEPROM. Data transfers from  
the SRAM to the EEPROM (the STORE operation) can  
take place automatically on power down. An internal  
capacitor guarantees the STORE operation regard-  
less of power-down slew rate. Transfers from the  
EEPROM to the SRAM (the RECALL operation) take  
place automatically on restoration of power. Initia-  
tion of STORE and RECALL cycles can also be con-  
trolled by entering control sequences on the SRAM  
inputs. The STK16C88 is pin-compatible with 32k x  
8 SRAMs and battery-backed SRAMs, allowing direct  
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™ operation.
