Part Number:BR25H640FVT-2CE2
Manufacturer:Rohm Semiconductor
Availability:0
Pricing$0.84
SkyChip No.:YG4ZN-BR25H640FVT-2CE2TR
Substitution Analysis:The BR25H640FVT-2CE2 matches the original device in density, organization, interface, and package. However, it presents a key limitation: its operating voltage range is narrower (2.5 V–5.5 V vs. 1.8 ... View More
Part Number:BR25S640FV-WE2
Manufacturer:Rohm Semiconductor
Availability:0
Pricing$1.08
SkyChip No.:KRBJ4-BR25S640FV-WE2TR
Substitution Analysis:From a core functionality and parameter perspective, the BR25S640FV-WE2 demonstrates high feasibility for substitution. Its key advantage lies in its clock frequency of up to 20MHz (compared to 10MHz ... View More
