FM93CS46N is a low cost, hardware encryption module that applies to secure identification and authentication. It is a non-volatile memory, which is widely used in contactless smart identification applications, including access control system, payment system and others. In addition, it is also suitable for use in access control, card-to-host authentication and secure communication interface areas.

The FM93CS46N memory is organized as an 8K single port ored multiplexed EEPROM. The memory can be divided into segments with individual read, write and Individual Segment Protection. The memory has a small package size and is suitable for space-saving and low power applications.The memory of the FM93CS46N chip is organized as an 8K single port ored multiplexed EEPROM.

FM93CS46N Working Principle

FM93CS46N is designed with multiple security features and standards, including secure write protection, secure access control, and integrated anti-reverse engineering features. The secure write protection consists of a logic bridge that disconnects the data inputs from the device after power is turned off, preventing uncontrolled ESD has been established. Furthermore, the secure access control is used to prevent unauthorized entities from tampering with the EEPROM memory.

In addition, the integrated anti-reverse engineering features protect the chip from physical probes or attacks. The chip will detect external attempts to read the EEPROM content or bypass the write protection and then erase the memory. This provides a strong layer of hardware safeguards against malicious manipulation of the chip from outside sources.

FM93CS46N Application Field

FM93CS46N can be used for required authentication, database security, identification and access control. It is widely used in contactless smart card applications such as public transportation, access control, student cards, and financial application. The security features and highly secure write protection make the chip the ideal solution for applications that require secure identification and authentication.

FM93CS46N is also being used in automotive and automotive components field, especially in ESCL applications. Such electronic systems require a secure, reliable, secure and power saving memory solution and FM93CS46N can offer solutions to meet these requirements.

Furthermore, it is also used in wireless technologies and RFID tags. The FM93CS46N offers secure write protection and secure access control to make sure the content stored in the RFID tags are not tampered with. This makes it suitable for use in secure wireless applications such as door entry systems, attendance systems, animal identification and more.

Conclusion

The FM93CS46N is a secure, low cost, hardware encryption module that is widely used in contactless smart identification applications. It can be used for required authentication, database security, identification and access control. Furthermore, it is also used in automotive, automotive components and wireless technologies, especially in ESCL applications. The FM93CS46N offers secure write protection and secure access control, making it suitable for secure applications which require authentication.
