• Manufacturer Part Number: AT90SC12836RCT
• Description: Secure Microcontroller
• Manufacturer: ATMEL Corporation

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 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 AT90SC12836RCT uses the secureAVR
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
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.
Figure 1 shows the AT90SC12836RCT block diagram.
