STK11C68-5L35M

The STK11C68-5L35M is a high-reliability non-volatile static RAM (nvSRAM) module combining SRAM and EEPROM technologies. It is designed to retain data even when the power supply is lost, making it ideal for applications requiring data preservation during power failures. This device typically features a memory organization of 8,192 words by 8 bits, providing a storage capacity of 64 kilobits.
Operating at a voltage of 5V, the STK11C68-5L35M offers fast read and write access times, typically around 35 nanoseconds, ensuring quick data retrieval and storage. It supports unlimited read and write operations, like standard SRAM, but with the added advantage of non-volatility, which protects against data loss.
The package is often compact, making it suitable for various applications, including industrial control systems, communications equipment, and data logging devices. Its reliability and durability in maintaining data integrity ensure that it is an excellent choice for critical applications requiring robust memory solutions.
