AT90SC19236RU Datasheet
Description
The AT90SC19236RU is a low-power, high-performance, 8/16-bit microcontroller with ROM program memory, EEPROM
memory, based on the secureAVR enhanced RISC architecture.
By executing powerful instructions in a single clock cycle, the AT90SC19236RU 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 AT90SC19236RU 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 AT90SC19236RU 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.
Additional security features include logical scrambling on program data and addresses, power analysis countermeasures,
and memory accesses controlled by a supervisor mode.
