The Cypress Semiconductor STK12C68-SF45 is a high-speed static RAM featuring an integrated non-volatile element in each memory cell, utilizing QuantumTrap technology for enhanced reliability. This component provides unlimited read and write cycles for the SRAM portion, while the independent non-volatile data is stored in a highly reliable QuantumTrap cell.
Data transfer from SRAM to the non-volatile elements (STORE operation) occurs automatically during power down. Upon power up, data is restored to the SRAM (RECALL operation) from the non-volatile memory. Both STORE and RECALL operations can also be initiated via software control, and a hardware STORE can be triggered using the HSB pin.
Key electrical specifications include a memory size of 64Kbit (8K x 8Bit), a parallel interface, and an access time of 45 ns. The device operates with a supply voltage ranging from 4.5V to 5.5V and consumes a supply current of 65 mA. The operating temperature range is 0C to 70C.
Packaged in a 28-pin SOIC case, the STK12C68-SF45 is designed for surface mounting. Its dimensions are 18.49 mm in length, 8.78 mm in width, and 2.44 mm in height. This NVRAM/SRAM is suitable for applications requiring persistent data storage and fast read/write capabilities.
