Each byte transfer on the bus takes 8 clock cycles plus the start/stop overhead, so a 16-byte page write completes in roughly 160 µs — no waiting for an internal erase cycle. The 550 ns access time is the cycle time the host sees on reads; this is fast enough that the I2C bus itself, not the memory, is the throughput bottleneck. If your host controller already supports 1 MHz I2C, this part will not add latency. ## FRAM vs EEPROM — why this part exists The FM24C16B-GTR uses FRAM technology, which stores data in a ferroelectric crystal instead of a floating gate. This eliminates the write-cycle delay and endurance limits of EEPROM: writes complete in the same time as reads (no page buffer to manage), and the part is rated for trillions of write cycles rather than the typical 1 million cycles of an EEPROM. For applications that write configuration data frequently — like energy meters logging consumption every second — this part removes the wear-leveling overhead and write-time blocking that EEPROM requires. The trade-off is the 5V-only supply rail; the FM24CL64B-GTR is the 3.3V sibling if your bus runs at 2.7V to 3.6V. ## Package and footprint — 8-SOIC The footprint is standard for 8-SOIC; no exposed pad or thermal considerations beyond normal FR4 copper pour. It is ROHS3 Compliant, with no lead, mercury, cadmium, or other restricted substances above the threshold.","metaTitle":"FM24C16B-GTR F-RAM 16Kbit I2C 1MHz 8SOIC","metaDescription":"Cypress FM24C16B-GTR 16Kbit FRAM, I2C 1MHz, 550ns access, 4.5-5.5V, -40 to 85°C, 8-SOIC.
