The 8-UFDFN exposed pad package (supplier device package 8-UFDFPN, 2x3 mm) is a surface-mount, leadless package with a 0.50 mm pitch. ## Write-cycle timing and endurance The write cycle time is 5 ms for a word or page write — this is the time the SPI bus is held during a write operation. For a full 128Kbit rewrite, the total write time depends on page size and the number of pages.","metaTitle":"STMicroelectronics M95128-DFMC6TG EEPROM, 128Kbit, SPI","metaDescription":"STMicroelectronics M95128-DFMC6TG 128Kbit SPI EEPROM in 8-UFDFN package. 1.7V-5.5V supply, 20MHz clock, -40°C to 85°C.
