It stores non-volatile data over an SPI bus at up to 20 MHz, organized as 16K x 8 bits. ## 20 MHz SPI bus — throughput and timing The SPI interface runs at 20 MHz clock. ## Package and footprint — 8-TSSOP The 8-TSSOP package (4.40 mm width, 0.173\" body) is a standard small-outline footprint. It is surface-mount only — no through-hole variant. The supplier device package is 8-TSSOP. ROHS3 compliant — no exemptions that would trigger a PCN. The closest functional sibling in the same series is the M95080-DRMN8TP/K (8 Kbit, same 20 MHz SPI, same AEC-Q100 grade but 105°C max), which is a lower-density alternative — not a pin-compatible replacement. If you need 128 Kbit, this is the part.","metaTitle":"M95128-DWDW4TP/K EEPROM 128Kbit SPI 20 MHz AEC-Q100","metaDescription":"M95128-DWDW4TP/K 128Kbit SPI EEPROM, 20 MHz clock, -40°C to 145°C, AEC-Q100, 8-TSSOP.
