Translation - Japanese: SRAMのバッテリーバックアップについて - Community Translated (JA)
Question: Does Cypress recommend any lithium battery backup for SRAM's?
Cypress does not recommend any backup battery because, this varies from system to system. Its better to determine the system requirements and contact the battery manufacturer. But have a look at our NVSRAM series of products which retain the content when there is loss of power.
