Product details

Active production — what it means for the BOM line

The BR93H66RF-WCE2: ROHS3 compliant per the manufacturer's listing — no exemption-based restrictions for EU or similar regulated markets.

Memory size, interface, and speed — fit for parameter storage

Organised as 256 x 16 bits (4Kbit total), accessed via a standard Microwire serial interface running at 1.25 MHz clock frequency.

Temperature grade and package — under-hood ready

Housed in an 8-SOIC (0.173", 4.40 mm width) package, also designated as 8-SOP by ROHM. The body width is the narrow SOIC variant (150 mil), so the PCB footprint matches standard 8-pin SOIC land patterns — no special pad geometry required.
