نظرة عامة على المنتج
The FM25L16B-DGTR from Infineon (formerly Ramtron/Cypress) is a 16Kbit (2K x 8) serial F-RAM memory with SPI interface operating up to 20MHz. Offering 100 trillion (10^14) read/write cycles and 151-year data retention at 65°C, it provides NoDelay writes and serves as a drop-in EEPROM replacement. Housed in 8-TDFN (4×4.5mm), it operates from 2.7V to 3.6V.
