Description
AT90SC25672RCFT low-power, high-performance, 8/16-bit microcontroller with program memory, EEPROM data memory crypto-accelerator, based secureAVR enhanced RISC architecture. executing powerful instructions single clock cycle, AT90SC25672RCFT achieves throughputs close Millions Instructions Second (MIPS) MHz. Harvard architecture includes general purpose working registers directly connected ALU, allowing independent registers accessed single instruction executed clock cycle. AT90SC25672RCFT uses secureAVR that allows linear addressing code data well number functional security features. AT90SC25672RCFT features bytes high-performance EEPROM (fast erase/write time, high endurance).This allows system developers offer their customers true bytes EEPROM, while still being able remaining bytes their purposes (customization patches, example). ability EEPROM code space allows parts program memory reprogrammed in-system. cryptographic accelerator featured AT90SC25672RCFT AdvX, N-bit multiplier-accumulator dedicated performing fast encryption authentication functions. cryptographic routines executed secureAVR core which uses AdvX accelerator during encryption/decryption. AdvX based 32-bit technology, thus enabling fast computation power operation. AdvX supports standard finite fields arithmetic functions (including RSA, DSA, ECC) GF(2N) arithmetic functions (including ECC). Additional security features include power, frequency temperature protection logic, logical scrambling program data addresses, Power Analysis countermeasures memory accesses controlled supervisor mode. This product specifically designed Smart Cards mainly targets Access Control applications. block diagram AT90SC25672RCFT shown Figure
