SRAM Data Memory
Constant tables can be allocated within the entire program memory address space (see the
LPM – Load Program Memory and ELPM – Extended Load Program Memory instruction
description).
Timing diagrams for instruction fetch and execution are presented in

The AT90CAN32/64/128 is a complex microcontroller with more peripheral units than can be
supported within the 64 locations reserved in the Opcode for the IN and OUT instructions. For
the Extended I/O space in SRAM, only the ST/STS/STD and LD/LDS/LDD instructions can be
used.
The lower data memory locations address both the Register File, the I/O memory, Extended I/O
memory, and the internal data SRAM. The first 32 locations address the Register File, the next
64 location the standard I/O memory, then 160 locations of Extended I/O memory, and the next
locations address the internal data SRAM (see “ISRAM size”).
An optional external data SRAM can be used with the AT90CAN32/64/128. This SRAM will
occupy an area in the remaining address locations in the 64K address space. This area starts at
the address following the internal SRAM. The Register file, I/O, Extended I/O and Internal SRAM
occupies the lowest bytes, so when using 64 KB (65,536 bytes) of External Memory,
“XMem size” bytes of External Memory are available. See
