8Kbit EEPROM in a 2×3 mm footprint
The M95080-DFMC6TG is an 8Kbit serial EEPROM organized as 1K x 8 bits, accessed over an SPI bus at up to 20 MHz. The 1.7V to 5.5V supply range means it can sit on a 1.8V or 3.3V or 5V rail without a separate level translator — the same die works across the board's voltage domains. Housed in an 8-UFDFPN exposed-pad package (2×3 mm body), this is the space-saving variant of the M95080 family. The exposed pad on the underside needs a thermal-land pattern on the PCB — the datasheet's recommended footprint keeps the junction temperature within the -40°C to 85°C operating range.
SPI bus integration and write timing
The SPI interface uses the standard MISO/MOSI/SCK/CS lines — no special protocol handshake beyond the opcode set. The write cycle time is 5 ms per word or page, so a firmware routine that updates a 32-byte parameter block needs to budget that latency between the write command and the next bus transaction. At 20 MHz clock, a full 1K byte read completes in about 410 µs — fast enough for boot-loader parameter fetch or calibration-table load at power-up. The non-volatile retention is rated for 40 years at 85°C per the M95080 family datasheet, though the exact endurance figure (typically 4 million write cycles) is not in this listing's spec table.
Active lifecycle and compliance baseline
The part is sourced through independent distribution; availability and current pricing are confirmed at RFQ against the BOM quantity. The Tape & Reel packaging (Cut Tape option available) suits pick-and-place assembly in medium-to-high volume runs. The 8-UFDFPN package is MSL1 per ST's handling notes — no moisture bake required before reflow if the sealed reel seal is intact.
