On a 1 MHz I²C line (bit period 1 µs), that timing leaves enough margin for the master to clock out the address byte and still meet setup/hold windows — no need for wait-state insertion on most ARM Cortex-M or 8-bit MCU I²C peripherals. Compared to the FM24V01A-GTR (130 ns access time, 3.4 MHz clock), this part trades raw speed for a wider supply range and the same industrial temperature grade, which keeps the BOM simpler when the host isn't pushing the bus to its limit. No end-of-life notice, no last-time-buy deadline to track. The base product number FM24CL64 covers the whole density family, so if a future revision needs a different package or temperature range, the migration stays within the same Cypress F-RAM™ series.","metaTitle":"FM24CL64B-DGTR 64Kbit I²C FRAM, 1 MHz, 8-DFN","metaDescription":"Active 64Kbit FRAM from the F-RAM™ series, I²C interface at 1 MHz, 550 ns access time, 2.7V–3.6V supply, -40°C to 85°C.
