Description
The AT91SC464384RCU 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 AT91SC464384RCU features 384K bytes of high performance EEPROM (fast erase/write time, high endurance).
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.

Architectural Overview
The SC100 is a 3 stage pipeline, 32-bit RISC processor. It uses a Von Neumann Load/store architecture, this architecture
is characterized by a single data and address bus for instruction data. The SC100 processor employs a unique architectural strategy known as Thumb®, a super reduced instruction set that is ideally suited for high volume applications with
memory restrictions, and applications where code density is an important factor. Essentially, the SC100 processor has two
instruction sets:
• The standard ARM instruction set using 32-bit instructions and offering maximum performance
• The Thumb instruction set using 16-bit instructions and offering maximum code density
Both instruction sets operate on 8-bit, 16-bit and 32-bit data types.
The Thumb’s 16-bit instruction length allows it to achieve almost twice the density of standard ARM code, whilst retaining
most of the ARM performance advantage over a traditional 16-bit processor using 16-bit registers. This is possible because
the 16-bit Thumb instructions operate on the same 32-bit register set as the 32-bit ARM instruction set. Thumb code can be
up to 35% smaller than the equivalent ARM code, whilst providing 160% of the performance of an equivalent ARM processor connected to a 16-bit memory system.
