Product details

128Kbit SPI EEPROM for parameter storage

The STMicroelectronics M95128-DFMC6TG is a 128Kbit serial EEPROM organized as 16K x 8 bits, accessed via an SPI bus at up to 20 MHz.

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.

Frequently asked questions

What is the closest functional second-source to M95128-DFMC6TG?

The M95128-RDW6TP is a functional alternative with the same 128Kbit density, SPI interface, and 20 MHz clock, but it uses a different package (8-TSSOP) and has a slightly different supply voltage range (1.8V minimum vs 1.7V). The M95128-DFMC6TG will not drop into a board designed for the M95128-RDW6TP without a PCB layout change due to the different package footprint.

What compliance documentation does STMicroelectronics provide for M95128-DFMC6TG?

The part is ROHS3 compliant. STMicroelectronics provides a datasheet, material declaration, and typically a PCN notification service. No UL or IEC certification is listed for this EEPROM device.
