The Simtek STK10C68 is a fast static RAM(25, 30, 35, and 45ns), with a nonvolatile electrically-erasable PROM (EEPROM) element incorporated in each static memory cell. The SRAMcan be read and written an unlimited number of times, while independent nonvolatile data resides in EEPROM. Data may easily be transferred from the SRAMto the EEPROM (STORE), or from the EEPROMto the SRAM(RECALL) using the NE pin. It combines the high performance and ease of use of a fast SRAMwith nonvolatile data integrity.
1. 25, 30, 35 and 45ns Access Times 2. 12, 15, 20 and 25ns Output Enable Access 3. Unlimited Read and Write to SRAM 4. Hardware STORE Initiation 5. Automatic STORE Timing
The AS5C4009LL is organized as 524,288 x 8 SRAM utilizing a special ultra low power design process. ASI’s pinout adheres to the JEDEC standard for pinout on 4 megabit SRAMs. The evolutionary 32 pin version allows for easy upgrades from the 1 meg SRAM design. For flexibility in memory applications, ASI offers chip enable (CE) and output enable (OE) capabilities. These features can place the outputs in High-Z for additional flexibility in system design. This devices operates from a single +5V power supply and all inputs and outputs are fully TTL-compatible.
1. Ultra Low Power with 2V Data Retention (0.2mW MAX worst case Power-down standby) 2. Fully Static, No Clocks 3. Single +5V ±10% power supply 4. Easy memory expansion with CE\ and OE\ options 5. All inputs and outputs are TTL-compatible 6. Three state outputs
