Memory IC Procurement Notes

Verify the specific package variant, as suffixes indicate different physical footprints like SSOP or TSSOP. Confirm the RoHS compliance status directly with the manufacturer documentation. Check the current lifecycle status, as this series may be marked as Not Recommended for New Designs. Ensure the ordering code matches the required pin layout and voltage specifications for your circuit design.

Memory IC Selection Notes

Select this component when a 16 kbit Microwire interface is required within a compact 8-pin surface-mount package. Consider the 1.7 V minimum operating voltage for low-power applications. Verify that the 3 MHz clock speed meets the system timing requirements. Compare the 8-TSSOP-BJ footprint against available PCB space constraints relative to other BR93G86 variants.

Memory IC Part Context

This part belongs to the BR93G series of Microwire EEPROMs from ROHM Semiconductor. The series shares common electrical characteristics and pinouts across densities ranging from 1 kbit to 16 kbit. Variants differ primarily by storage capacity and package type, such as SOP, SSOP, or TSSOP. The BR93G86 specifically denotes the 16 kbit density level within this family.
