The Microchip 93C76-E/SN is an 8Kbit serial EEPROM using the Microwire three-wire interface, organized as 1K x 8 or 512 x 16 selectable by the ORG pin. The 10ms write cycle time per word or page is the latency to budget for when updating calibration tables or configuration blocks.
Package and mounting — 8-SOIC surface mount
The footprint matches any generic SO-8 land pattern.
That means Microchip continues to manufacture it with no announced last-time-buy or end-of-life notice. The ROHS3 compliance covers current EU and global RoHS requirements.
