Introduction

IS61NLP102418B-200B3L is one of the reliable and trustworthy memory products by Integrated Silicon Solution Inc. (ISSI). It is a one-time programmable (OTP) memory. It includes a mere 1,024 bits of nonvolatile memory and hence consumes a negligible amount of power. IS61NLP102418B-200B3L is a highly reliable and denser kind of memory in comparison with its EV versions. This has made it desirable for a ton of applications. The basic purpose for its development is to allow for system level-data storage, especially in remote systems where power consumption is a major concern.

Applications

IS61NLP102418B-200B3L has a few applications. Some of them are listed below.

• It is mainly used for appliance and battery-operated device logging/storage.
• It is generally used as on-board knowledge or system data storage that can eventually help with fault analysis.
• It is an optimal memory for hard-to-reach applications, majorly the ones in need of a relatively long battery life.
• It is very suitable in situations where either there is a lack of space or the system setup prevents the use of other types of memory.
• It is also successfully used in situation-based testing/certification.

Working Principle

IS61NLP102418B-200B3L is powered by a link controller that acts as the interface between the EEPROM and the application microcontroller. The link controller is responsible for the functions of writing, reading and erasing the OTP memory. It also ensures that the memory data remains secure and only authenticated devices are allowed to access it. For authentication, the controller utilizes the sRead and sWrite commands. The sRead command requires the user to enter valid authentication data which is used to unlock the protected area. If the authentication data is incorrect, the sRead command will be blocked. The sWrite command needs the user to enter a valid password which is necessary for writing in the protected area of the memory.

Conclusion

IS61NLP102418B-200B3L is a very reliable and popular memory product by ISSI. It is a one-time OTP memory that is power-efficient and occupies minimum space. This feature makes it a popular choice for hard-to-reach applications and for logging and storing data in battery-powered devices. It is enabled by a link controller which ensures that the data remains secure from unauthorized access. Its wide range of applications make it one of the top-selling memories worldwide.
