8-SOIC footprint and board integration
The FM24CL04B-G is supplied in an 8-SOIC package (0.154-inch body width, 3.90 mm) with a surface-mount footprint that matches industry-standard SOIC-8 land patterns — no special pad geometry or thermal-via array required for this 4Kbit FRAM. Supply voltage spans 2.7 V to 3.6 V, so the part sits comfortably on a 3.3 V rail without an external regulator; the I²C interface runs at 1 MHz clock frequency, compatible with most MCU I²C peripherals.
Parametric profile for the BOM line
Organised as 512 x 8 bits, the FM24CL04B-G delivers 4Kbit of non-volatile FRAM with a 550 ns access time — write cycles consume no erase time, unlike EEPROM, so the effective write throughput at 1 MHz I²C is limited only by the bus protocol overhead. Rated for -40°C to +85°C ambient, the device covers industrial temperature range; the FRAM cell retains data without a backup battery, eliminating the battery holder and monitoring circuit from the BOM.
Lifecycle and compliance posture
Sourced through independent distribution channels; availability and current pricing are confirmed at RFQ against the BOM quantity.
