Development Tools and Software

Description

The AT91SC192192CT-USB is a low power, high performance, 32-bit RISC microcontroller with Flash/Eeprom program

and data memories and cryptographic accelerator, based on the ARM SC100 advanced secure processor. This general

purpose 32-bit processor offers high performance, very low power consumption, and additional features to help combat

fraud.

The AT91SC192192CT-USB features 192K bytes of high performance Flash (fast erase/write time, high endurance).

The AT91SC192192CT-USB features 192K bytes of high performance Eeprom (fast erase/write time, high endurance).

The AT91SC192192CT-USB also features a USB full speed 2.0 port to allow very high speed transactions with a USB host

terminal. USB interface requires the addition of an external 48MHz resonator.

The AT91SC192192CT-USB features a SPI (Serial Peripheral Interface) port to provide either high speed interface with

external terminal or to connect external NOR Flash memory. It also features an interface for NAND Flash memory.

On top of the SC100s MPU, a real hardware firewall can be used to increase the overall security level of the application

without intense software development.

performing fast encryption and authentication functions. AdvX is based on a custom 32-bit co-processor, thus enabling fast

computation and low power operation. The AdvX in conjuction with controlling firmware running within the SC100 core,

supports standard finite arithmetic functions (including RSA, DSA, DH and ECC) and GF(2N).

Unique hardware features significantly accelerate the execution of Java Card Byte Code by removing the common

software bottlenecks encountered during the implementation of a Java Virtual Machine.

Additional security features include power and frequency protection logic, logical scrambling on program data and

addresses, power analysis countermeasures, and memory access controlled by a supervisor mode.

Pin Configuration

The AT91SC192192CT-USB pinout configuration confirms to the ISO7816-2 interface.
