Description
The AT90SC12836RCFT is a low-power, high-performance, 8-/16-bit microcontroller with ROM program memory, EEPROM data memory,
based on the secureAVR enhanced RISC architecture and with a dual interface (contact+contactless).
By executing powerful instructions in a single clock cycle, the AT90SC12836RCFT achieves throughputs close to 1 MIPS per MHz. Its
Harvard architecture includes 32 general-purpose working registers directly connected to the ALU, allowing two independent registers to be
accessed in one single instruction executed in one clock cycle.
The AT90SC12836RCFT uses the secureAVR architecture that allows the linear addressing of up to 8M bytes of code and up to 16M bytes
of data as well as a number of new functional and security features.
The AT90SC12836RCFT features 36K bytes of high-performance EEPROM (fast erase/write time, high endurance). The ability to map the
EEPROM in the code space allows parts of the program memory to be reprogrammed in-system.
The cryptographic accelerator featured in the AT90SC12836RCFT is the new AdvX, a N-bit multiplier-accumulator dedicated to performing
fast encryption and authentication functions. All cryptographic routines are executed on the secureAVR core which uses the AdvX
accelerator during encryption/decryption. AdvX is based on a 32-bit technology, thus enabling fast computation and low power operation.
AdvX supports standard finite fields arithmetic functions (including RSA, DSA, DH and ECC) and GF(2N) arithmetic functions (including
ECC).
Additional security features include power, frequency and temperature protection logic, logical scrambling on program data and addresses,
power analysis countermeasures, and memory accesses controlled by a supervisor mode.
This product is specifically designed for Smart Cards and targets Access Control and ID applications.
