Comparison Between AT90CAN32, AT90CAN64 and AT90CAN128
Part Desription
AT90CAN32/64/128
AT90CAN32, AT90CAN64 and AT90CAN128 are all hardware and software compatible with
each other, the only difference is the memory size.
Table 1-1.
The AT90CAN32/64/128 is a low-power CMOS 8-bit microcontroller based on the AVR
enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the
AT90CAN32/64/128 achieves throughputs approaching 1 MIPS per MHz allowing the system
designer to optimize power consumption versus processing speed.
The AVR core combines a rich instruction set with 32 general purpose working registers. All 32
registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent
registers to be accessed in one single instruction executed in one clock cycle. The resulting
architecture is more code efficient while achieving throughputs up to ten times faster than con-
ventional CISC microcontrollers.
