The 20 MHz clock rate delivers read throughput suitable for storing configuration parameters, calibration constants, and firmware look-up tables in embedded systems. ## Supply voltage and temperature grade The 5ms page write cycle is consistent across this range, so write timing does not need derating at the cold end. ## Package and board-fit Housed in an 8-TSSOP (4.40 mm body width), the part mounts on a standard SOIC-8 footprint with a finer pitch — the 0.65 mm lead pitch requires a soldermask-defined pad. Tape & Reel (TR) and Cut Tape (CT) options are available, so the same order code covers prototype quantities and production reels. The part is ROHS3 compliant, meeting the latest EU restriction directive without exemption.","metaTitle":"STMicro M95256-DFDW6TP 256Kbit SPI EEPROM, 8-TSSOP","metaDescription":"256Kbit SPI EEPROM, 20 MHz clock, 1.7V-5.5V supply, -40°C to 85°C, 8-TSSOP.
