Description
AT90SC12836RCT is a low power, high performance, 8/16-bit microcontroller based on the secureAVR™ enhanced RISC
architecture, with ROM program memory and EEPROM data memory. By executing powerful instructions in a single clock
cycle, the AT90SC12836RCT achieves throughputs close to 1 MIPS per MHz. Its Harvard architecture includes 32 generalpurpose working registers directly connected to the ALU, allowing two independent registers to be accessed in one single
instruction executed in one clock cycle.
The AT90SC12836RCT uses the secureAVR™ this 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 AT90SC12836RCT includes 36K bytes of Atmel’s high density, non volatile memory.
The crypto engine featured in the AT90SC series is the AdvX™, a 32-bit accelerator dedicated to perform fast encryption or
authentication functions.
Additional security features include power and frequency protection logic, logical scrambling on all data and addresses,
Power Analysis countermeasures and memory accesses controlled by a supervisor mode.
