EM4233
2k bit Read/Write High Secure
ISO15693 Standard Compliant Device
General Description
The EM4233 is a long range passive CMOS integrated
circuit intended for use in applications requiring a
contactless read/write memory offering a high and tailored
level of security.
The configurable 2k bit EEPROM memory included in the
chip is organized in 64 words of 32 bits. The high level of
flexibility in the memory management, permits that a
memory word can be read/write protected and/or locked
separately.
This latest generation of EEPROM memory offers data
retention of 60 years enabling solutions for long-term asset
management applications.
The customer data privacy and security is guaranteed by a
powerful and fast crypto engine implemented in the chip
associated with a true random generator and a 96 bit secret
key.
The enhanced on-chip security feature permits a flexible
administration of the memory access rights which makes it
the right solution for advanced theft protection.
Depending on the application requirements, in terms of
security, the user can tailor and adjust the security level by
selecting either a true mutual authentication process, a login
procedure with a 32 bit password or use the chip as a plain
text memory.
The IC supports all the ISO15693 Mandatory commands
and many of the optional commands. Its command set is
completed by unique custom commands which give to the
EM4233 customers a higher degree of differentiation in
terms of security, flexibility and data protection.
Each EM4233 contains in its memory a 64 bit unique serial
number which cannot be altered and guaranties the
uniqueness of each device.
