• Description: Chip Card & Security
• Manufacturer: Infineon Technologies Corporation

The SLE 76C1440P is a member of the streamlined SLE 76P-series of Infineon Technologies optimized for
mobile communication applications. This security controller is manufactured in advanced 0.13 µm CMOS
technology. It has a defined migration path from existing SLE 66C(L)xxxPE products with minimized
customer effort to migrate the OS and is based on the same tool set.
The internal clock frequency can be adjusted to a level of up to 33 MHz either as a multiple of 1 to 8 of the
external frequency or independent of the clock rate of the terminal with the help of the internal clock. It is
adjustable according to either available power requirements or required performance:

The Interrupt and Peripheral Event Channel Controller (ITP) can process interrupt requests from different
sources to run an interrupt service routine (ISR). Data can be directly transferred between memory locations
with a minimum of CPU activity for fast interaction with peripherals using so-called Peripheral Event
Channels (PECs). The channels can be assigned individually to peripherals or chained together to enable
continuous transfer without handover delay between the channels.
The enhanced CRC module allows the easy generation of checksums according to ISO/IEC 3309 (16-Bit-
CRC) and offers a loadable initialization vector for a better Java support.
To minimize the overall power consumption, the chip card controller IC offers a sleep mode.
The improved UART supports the half-duplex transmission protocols T=0 and T=1 according to ISO/IEC
7816-3 as well as a larger FIFO and a clock division factor of 8. All relevant transmission parameters can be
adjusted by software, as e.g. the clock division factor, direct/inverse convention and the number of stop bits.
Additionally, the I/O port can be driven by communication routines realized in software.
The pseudo random number generator (PRNG) is able to supply random numbers.
The watchdog timer (WDT) is a circuit that monitors controller operation by automatically initiating a security
reset if a specified period without an adequate response elapses after occurrence of a hardware or software
irregularity.
In conclusion, the SLE 76C1440P fulfills all requirements of today's mobile communication smart card
applications. In addition, it offers a powerful platform for multi application cards based on Java.
The SLE 76C1440P integrates outstanding memory sizes and peripherals in combination with enhanced
performance and optimized power consumption on a minimized die size.
