KS8995MAI

KS8995MAI Allgemeine Beschreibung

When it comes to durability, the KS8995MAI excels with its wide operating temperature range of -40°C to 85°C and ESD protection on all ports. This means that it can withstand harsh industrial environments without compromising on performance. Additionally, its compact 128-pin LQFP package and support for both 3.3V and 1.8V power supplies make it a flexible choice for different system requirements
