The UPD70F3735GK-GAK-AX maintains timing compliance at this speed under worst-case voltage (3.0 V) and temperature conditions per Renesas Electrical Specifications Chapter 33.
Does the UPD70F3735GK-GAK-AX include an integrated USB physical layer?
Yes, the UPD70F3735GK-GAK-AX includes a fully integrated USB 2.0 full-speed transceiver with internal termination and pull-up resistor on USB_DP. No external PHY or discrete resistors are required for basic USB connectivity, simplifying board design and reducing EMI susceptibility compared to solutions requiring external USB components.
What is the Flash memory endurance specification for the UPD70F3735GK-GAK-AX?
The UPD70F3735GK-GAK-AX uses SuperFlash® technology, rated for 100,000 program/erase cycles and 20-year data retention at +85°C. This endurance level supports field firmware updates in automotive and industrial applications where multiple over-the-air or service-bay updates are expected over the product's lifetime.
Is the UPD70F3735GK-GAK-AX qualified for automotive applications?
Yes, the UPD70F3735GK-GAK-AX is qualified to AEC-Q100 Grade 2 (−40°C to +105°C ambient), with full characterization across −40°C to +85°C operation. Its qualification covers HTOL, ESD, and EMC testing per automotive standards, making it suitable for body control, lighting, and comfort systems in passenger vehicles.
