Description
The
AT91SO100/101, AT91SO50/51
and the
AT91SO25
are 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 SC100 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.
The
AT91SO100/101, AT91SO50/51
and the
AT91SO25
have internal EEPROM that can be used as program or data memory. It also
includes a ROM (for the bootstrap and crypto library and some native functions) and a large SRAM. The
AT91SO100/101
can also
address up to 16Mbytes of external memory.
The
AT91SO100/101, AT91SO50/51
and the
AT91SO25
also comprises of strong security mechanisms and has a impressive set of cry-
tography 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.
The
AT91SO100/101, AT91SO50/51
and the
AT91SO25
includes a lot of dedicated peripherals as ISO 7816 controller and mag-
netic stripe card interface, as well as USB, SPI, TWI, USARTs and I/O ports.
The
AT91SO101
is a single package solution in BGA256 embedding two chips, the secure controller and the AT83C26 which physically
interface with up to 2 smart cards and 3 secure access module, or 1 smart card and 4 secure access module.
The
AT91SO100
is available using the same package (BGA256) pin to pin compatible with the AT91SO101 but without the AT83C26.
The
AT91SO51
is a single package solution in BGA208 (cost effective solution) embedding two chips, the secure controller and the
AT83C26 which physically interface with up to 2 smart cards and 3 secure access module, or 1 smart card and 4 secure access module.
The external bus is not connected on this product.
The
AT91SO50
is available using the same package (BGA208) pin to pin compatible with the AT91SO51 but without the AT83C26. The
external bus is not connected on this product.
The
AT91SO25
is a single package solution in BGA144 (low cost solution) embedding one chip, the secure controller
only.
The external
bus is also not connected on this product.
