Translation - Japanese: バージョンの標準、LとLLの違いについて。
Question: What are the differences between the Standard, L version and LL version?
The differences are the amount of current each part draws when it is in standby or data retention mode. Referring to the datasheet, you will see differences in Isb2 as well as in Iccdr. The L version has lower Isb2 and Iccdr than the "Standard" version, where the LL version has very lower characteristics compare to "Standard" and L version.
