Description The AT90SC19236RT is a low power, high performance, 8/16-bit microcontroller based on the SecureAVR enhanced RISC architecture, with flexible ROM program memory and EEPROM data memory. By executing powerful instructions in a single clock cycle, the AT90SC19236RT 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 AT90SC19236RT uses the SecureAVR 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 security features. The ability to map the EEPROM in the code space allows parts of the program memory to be reprogrammed in-system. This technology combined with the versatile 8/16-bit CPU on a monolithic chip provides a highly flexible and cost-effective solution to many smartcard applications. The AT90SC19236RT benefits from advanced EEPROM functions (XP Mode), but can also be configured to offer compatibility with the AT90SC19236R. Additional security features include power and frequency protection logic, logical scrambling on program data and addresses, power analysis countermeasures, and memory accesses controlled by a supervisor mode.
