The part comes in an 8-DFN exposed-pad surface-mount package (4x4.5 mm). ## 20 MHz SPI and no write delays The 20 MHz SPI clock is the bus speed limit; FRAM writes complete in a single SPI cycle with no page-write or erase overhead. For a design that logs sensor data every 10 ms, this eliminates the 5 ms EEPROM page-write penalty that can stall the bus. The 2.7 V minimum supply means the part stays alive through a 3.3 V rail droop to 2.7 V, which is useful in battery-backed or capacitor-hold scenarios. For dual-sourcing resilience, the FM25L16B-G is a pin-compatible sibling in a different package variant (SOIC-8); confirm the footprint before substituting.","metaTitle":"Cypress FM25L16B-DG 16Kbit FRAM, 20 MHz SPI, 8-DFN","metaDescription":"Cypress FM25L16B-DG F-RAM non-volatile memory: 16Kbit (2K x 8), 20 MHz SPI, 2.7V-3.6V, -40°C to 85°C, 8-DFN exposed pad.
