For a 1 Kbyte block, the transfer takes roughly 3 ms at 3 MHz, but the write cycle time of 5 ms per word or page is the real bottleneck — the bus clock only matters for the read-back and command phase. If the host controller runs a slower SPI or Microwire port, the 3 MHz ceiling is not a limitation; the part will clock at any frequency below that. ## Supply range and write cycle — design decisions The 5 ms write cycle time per word or page is typical for this density — if the application writes configuration data infrequently (e.g., at power-up or on a calibration event), the 5 ms delay is invisible. For streaming writes, the Microwire interface requires the host to poll the READY/BUSY status after each write command. The RoHS compliance status is listed as non-compliant, so verify your assembly's exemption or use the RoHS-compliant suffix variant if needed. ## Package and footprint The supplier device package is 8-MSOP, which matches the 8-TSSOP and 8-MSOP case codes listed.","metaTitle":"Microchip 93LC76C-I/MS EEPROM, 8Kbit, Microwire, 3 MHz","metaDescription":"Microchip 93LC76C-I/MS 8Kbit EEPROM with Microwire interface, 3 MHz clock, 2.5V-5.5V supply, -40°C to 85°C.
