The 25LC160CT-I/SN, produced by Microchip Technology Inc, is an E²CMOS™ nvSRAM with an integrated Nonvolatile Controller (NVC). It is a low power SRAM with a very wide operating range from -40°C to +85°C with an additional Endurance of 1000 Write Cycles and Data Retention of 40 years.

This device has been designed to provide high-speed access to a zero-power source of volatile SRAM memory. The Nonvolatile Controller (NVC) automatically stores the data in the 25LC160CT-I/SN when the power is removed and restores the data when power is reapplied. This eliminates the need for internal battery back-up functions, thus allowing the processor to start right up with the previous data without any user intervention. Additionally, the 25LC160CT-I/SN supports an 100kHz serial instruction interface, providing the user with maximum flexibility in addressing the SRAM.

Due to its extremely low power requirements, the 25LC160CT-I/SN is ideal for systems that need to process information in real-time, such as industrial automation and process control applications. The extremely low power requirements also allow it to be used in battery-powered and portable equipment such as radios and cell phones. Furthermore, the integrated NVC allows the device to be used in data logging applications and as a repository for frequently changing settings.

The 25LC160CT-I/SN is a 16Kb nonvolatile SRAM which possesses a number of features to assure reliability and data security. These features include a write protection facility, a self-timed write cycle, and a low active current of just 6mA. Additionally, the 25LC160CT-I/SN supports write sequences to any address locations within the memory, allowing it to be used where frequent data logger updates are needed. This enables it to be used for data logging with minimal power dissipation, since the device does not require any additional circuitry for redundant battery back-up.

The 25LC160CT-I/SN\'s working principle lies in the fact that it uses a Nonvolatile Controller (NVC) to store data in the SRAM. This NVC is responsible for both storing data into the SRAM when power is removed and restoring the data when power is reapplied. The 25LC160CT-I/SN also supports an instruction set designed to aide in the data logging process.

The 25LC160CT-I/SN has a wide range of practical applications that benefit from its small size and low power consumption. It is ideal for use in medical/biomedical monitoring systems, industrial/process control systems, small-scale data loggers, and portable/handheld systems. The fact that it can enforce write protection allows it to be used in applications where system data must be protected from unauthorized changes. The unique way in which it stores data in the SRAM by using its nonvolatile controller makes it the perfect choice for any application that necessitate frequent logging or updating of data with minimal impact on system power consumption.
