The SRAM can be read and written an unlimited number of times, while independent nonvolatile data resides in EEPROM. Data transfers from the SRAM to the EEPROM (STORE), or from the EEPROM to the SRAM (RECALL) are initiated through software se- quences. It combines the high performance and ease of use of a fast SRAM with nonvolatile data integrity. The STK11C68-M is pin compatible with industry stan- dard SRAMs and is available in a 28-pin 300 mil ceramic DIP or 28-pad LCC package. Commercial and industrial devices are also available. FEATURES • 35, 45 and 55ns Access Times • 17, 20 and 25ns Output Enable Access • Unlimited Read and Write to SRAM • Software STORE Initiation • Automatic STORE Timing • 100,000 STORE cycles to EEPROM • 10 year data retention in EEPROM • Automatic RECALL on Power Up • Software RECALL Initiation • Unlimited RECALL cycles from EEPROM • Single 5V ± 10% Operation • Available in multiple standard packages A A A A A A A A A A DQ DQ DQ G A E DQ NC 6 5 4 3 2 1 0 0 1 8 9 11 10 7 6 TOP VIEW 4 5 6 7 8 9 10 11 12 32 1 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 |
