The 2.5V to 6.0V supply range lets it straddle 3.3V and 5V logic domains without a regulator — a single BOM line that covers both rails. Write cycle time is 5 ms per word or page, which sets the firmware timing budget for non-volatile store operations. ## Supply range and clock speed The 2.5V to 6.0V supply range is wider than the 2.5V-only rail on the 93LC46B/SN sibling, which means the 93LC76/SN can be used in mixed-voltage designs without a separate EEPROM variant per rail. At 3 MHz the Microwire clock is 1 MHz faster than the 2 MHz limit of the 93LC46B/SN — a meaningful throughput gain when the host controller supports the higher rate. ## Active production and compliance ROHS3 compliant, no AEC-Q grade listed, so the part is suited for commercial/industrial environments within the 0°C to 70°C ambient range.","metaTitle":"93LC76/SN Microchip EEPROM 8Kbit Microwire 8-SOIC","metaDescription":"93LC76/SN Microchip EEPROM, 8Kbit, Microwire interface, 3 MHz clock, 2.5V–6.0V supply.

Both use the Microwire interface and share the same 8-SOIC footprint, but the larger memory size means the address space differs — the host controller must support the 93LC76/SN's addressing scheme.
