AT91SO100

6514BS–SMIC–26Oct05

Description

AT91SO100 is a low-power, high-performance, SC100 32-bit microcontroller based on the ARM® enhanced RISC architecture. This new

SC100 core allows the linear addressing of up to 1M bytes of code and data as well as a number of new functional and security features.

A 3-level instruction pipeline allows the performance of one instruction in a single clock cycle, the AT91SO100 achieves throughputs

close to 1 MIPS per MHz. 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.

AT91SO100 has internal EEPROM that can be used as program or data memory. It also includes a ROM (for the boot and some native

functions) and a large SRAM. AT91SO100 can also address, via pages, up to 16Mbytes of external memory.

The AT91SO100 also comprises of strong security mechanisms and has a impressive set of crytography features , hardware DES/TDES,

hardware AES, hardware SHA-n, hardware cryptography accelerator for asymmetric algorithms (RSA, Elliptic Curve, Key generation)

and a true random number generator.

AT91SO100

includes a lot of dedicated peripherals as smart card and magnetic stripe card interface, as well as USB, SPI,

UARTs and I/O ports.

physically interface with up to five smart cards.
