The DS1345BL-100 is a non-volatile static RAM (NVSRAM) that uses an auxiliary power source and three non-volatile memory cells to provide high Speed and low power consumption for a wide range of applications. Through the use of Ultralow power consumption logic and a groundbreaking architecture, the DS1345BL-100 offers robust performance, enhanced security, and a wide operational temperature range. In this article, we will discuss the application fields of the chip, as well as its working principle.
Application Fields
The DS1345BL-100 finds a wide range of applications in embedded systems, automotive, avionics and industrial process control.- - Embedded systems - With its Ultralow power consumption logic and highly reliable non-volatile memory cells, the DS1345BL-100 is ideal for use in embedded systems, such as environments or applications that require extended operational time without changed configurational parameters or settings. Proprietary applications benefit from the built-in AES-CBC encryption algorithm, which provides secure data storage for sensitive applications.
- - Automotive - The chip\'s low power consumption and extended operational temperature range make it well suited for use in automotive applications, such as in vehicle systems. The chip\'s wide variety of output configurations—including CMOS, TTL/CMOS logic levels, serial bus, and analog—allow it to integrate seamlessly with a variety of automotive systems.
- - Avionics & Industrial Process Control - The DS1345BL-100\'s low-power design and enhanced security features make it a suitable choice for avionic applications, such as the control of fuel or other instrumentation in an aircraft. The chip\'s robust design, low power consumption, and wide operational temperature range make it well suited for use in industrial process control applications, such as hazardous environment monitoring.
Working Principle
The DS1345BL-100 utilizes a combination of logic and non-volatile memory cells to provide reliable and Low-power performance. The non-volatile memory cells are divided into two types: Read/Write Cells and Sleep Cells.- Read/Write Cells: The Read/Write Cells are used to store the application data and instructions. These memory cells typically consume more power than the Sleep Cells, but they provide the fastest access to the application data.
- Sleep Cells: The Sleep Cells are used to store the application data and instructions in a low power state. These cells typically consume less power than the Read/Write Cells, but they provide slower access to the application data.
- Address Decoder: The address decoder is responsible for decoding the address bus and providing the proper signals to the memory cells.
- Data Register: The data register is responsible for transferring data between the memory cells and the data bus interface.
- Auxiliary Power Source: The auxiliary power source is responsible for providing the necessary source of power for the non-volatile memory cells, as well as the necessary protection circuitry to ensure reliable operation.
