The FM24C04B-G is a 4-Kbit ferroelectric random access memory (F-RAM) organized as 512 × 8 bits and accessed via I2C. It features NoDelay™ writes at bus speed, eliminating EEPROM write delays. Supporting 100 trillion (1014) read/write cycles and 151-year data retention at 65°C, it operates from 4.5 V to 5.5 V with 100 μA active current at 100 kHz and 4 μA standby. AEC-Q100 Grade 3 qualification and –40°C to +85°C range suit frequent, rapid-write applications.
