Software Libraries and Application Notes
Description
The AT91SC512384RCT is a low power, high performance, 32-bit RISC microcontroller with ROM program memory,
EEPROM data memory, 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 AT91SC512384RCT features 384K bytes of high performance EEPROM (fast erase/write time, high endurance).
The AT91SC512384RCT 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 AT91SC512384RCT 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.
The cryptographic accelerator featured in the AT91SC series is the AdvX, an N-bit multiplier-accumulator dedicated to
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 AT91SC512384RCT pinout configuration confirms to the ISO7816-2 interface.
Note: By convention, the RST pin corresponds to the RST signal of the ISO7816-3 Protocol, both are active low.)
