EM4233 chip cards / High Secure ISO15693 EM4233 chip(replaces
EM4035 and EM4135 chip)
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
during 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 allows 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 guarantees the uniqueness of each
device.
