At 1 MHz I²C, each bit takes 1 µs, so the access is inside one clock cycle — no wait-state insertion needed on the master side. The limiting factor for throughput is the bus speed, not the memory array.

The FM24C04B-G is pin-compatible with a 24C04 and uses the same I²C protocol. The key difference: FRAM writes at bus speed with no write-cycle delay, so no polling or page-write wait is needed. The 1 MHz clock rate is also faster than the 400 kHz typical of most 24C04s. Verify the supply voltage — this part runs on 4.5 V to 5.5 V, not 2.7 V to 5.5 V like some low-voltage 24C04 variants."},{"question":"What is the difference between FM24C04B-G and FM24C04?","answer":"FM24C04 is the base product number for the 4Kbit FRAM family. The FM24C04B-G is a specific variant: it operates at 4.5 V to 5.5 V supply and comes in an 8-SOIC package. Other variants like FM24CL04B-G run at 2.7 V to 3.6 V. The 'B' suffix typically indicates a specific revision or temperature range."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/FM24C04B-G","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/FM24C04B-G when reusing this data.
