AT28C641B-15SU-T is a unique type of memory component that is used in a wide range of applications. It is a type of non-volatile memory, meaning that data stored on the component is retained even when the component is powered off. This component is often found in embedded systems, which are systems where a computer is embedded in the hardware of a device. It is also used in many industrial, military, and aerospace applications. To understand the AT28C641B-15SU-T, it is important to understand both its application field and its working principle.

Application field

The AT28C641B-15SU-T is an 8Kx8 Nonvolatile SRAM component that is specifically designed for embedded systems. It is used in applications such as automation, medical, security, and transportation applications. The component is highly reliable and has a wide range of features that make it suitable for these applications. For example, it offers low power consumption, fast access times, and data retention of up to 20 years.

The component is also designed for use in high temperature and high radiation environments. It comes with an industrial temperature range of -40°C to +125°C, making it suitable for extreme temperature operations. It also has high radiation tolerance and is immune to Single Event Upset (SEU) and Single Event Latchup (SEL) events. This makes the component ideal for applications in military and aerospace environments.

Working principle

The AT28C641B-15SU-T is composed of SRAM cells and non-volatile cells. The SRAM cells are fast and retain data while the component is powered on. The non-volatile cells are slower, but retain data even when the component is powered off. This combination of SRAM and non-volatile cells allows for data to be retained for a prolonged period of time, even when the component is powered off.

The data retention of the component is achieved by using a small amount of power during a standby mode. This standby power is supplied to the non-volatile portion of the component which causes the charges in the cells to recharge and maintain data integrity. The recharge process is automatic and requires no intervention from the user.

The AT28C641B-15SU-T also contains special circuitry to ensure that data is written correctly and is always reliable. For example, it includes a hardware-based error detection circuitry which can detect write errors and prevent them from occurring. It also includes a self-timed write algorithm which ensures that data is written at a speed that is slow enough to prevent data corruption.

Conclusion

The AT28C641B-15SU-T is a unique type of memory component that is used in a variety of embedded system applications. Its combination of SRAM and non-volatile cells allows it to retain data for a prolonged period of time and makes it suitable for use in highly reliable and demanding applications. Its low power consumption, fast access times, and data retention of up to 20 years make it an ideal choice for embedded applications in industrial, military, and aerospace environments.
