Data transmission up to 212 Kbit/s
ISO 7816 Interface
32.5 KBytes EEPROM
128 KBytes ROM

D u a l I n t e r f a c e :
The dual interface chip AE45X belongs to the high security
smart card controller family of Hitachi. It combines the
security features of the ISO 7816 compliant standard AE4
products, with the advantages of an additional contactless
interface according to the ISO 14443 type B or C. The
AE45X is manufactured using a highly reliable 0.35 μm
shrink CMOS process providing outstanding memory sizes.
In contactless mode the power supply and bi-directional
data transmission is done via a coil connected to the
AE45X. The coil is tuned to an operating frequency of
13.56 MHz, basis of a proximity card system. It provides a
high data transfer rate of 212 Kbit/s (max) at a distance of
up to 10 cm, and fulfils the requirements of most of the
contactless smart card applications in terms of
performance and cost.
Compared to standard contact based smart cards, this
system works without any physical contact between the
terminal and the smart card, resulting in low maintenance
costs and reliable functionality in adverse environmental
conditions. The fast and high security data transfer
combined with its convenient handling makes it best suited
for various applications. Additionally, by using the
integrated anti-collision method several cards can be
operated on one terminal simultaneously.
I n t e g r a t e d S e c u r i t y C o n c e p t :
The AE45X designed under Hitachi’s Integrated Security
Concept is ideally suited for high security applications. The
ISC means that security is not just an add-on feature to
standard modules or cores, security has been built-in from
the start, forming an integral part of the whole Smart card
design concept. The whole ISC process e.g. secure chip
design environment, secured production facilities and
secure handling during shipment to the customer are
constantly reviewed in order to maximise the overall security
package. All devices of the AE-series will be evaluated and
certified by independent evaluation authorities.
Many security features such as integrated sensors,
distributed layout, random number generation, watchdog
timer, DES engine, Firewall Management Unit (FMU) and
power analysis attack protection are included providing a
strong ON-CHIP hardware security structure.
Uniquely, Hitachi smart card devices are fabricated using a
MONOS (Metal Oxide Nitride Oxide Silicon) EEPROM
structure. MONOS advantages compared to standard
EEPROM structures are: high resistance to radiation
disturbance, high reliability and endurance.
A high performance Coprocessor is complementary to the
design concept ensuring final operation system efficiency,
application integrity and performance that meet
tomorrow’s needs today.
A p p l i c a t i o n s :
The AE45X fulfils the requirement of Smart Card
applications for large memories, high security and high-
speed secure authentication, data encryption or electronic
signature, as well as secure contactless data transmission.
This multi-application capability combines the standard
