FAQ
What is the maximum operating frequency of the UPD70F3770GC-UEU-AX?
The UPD70F3770GC-UEU-AX operates at a maximum frequency of 40 MHz when using its internal PLL with an external 8 MHz crystal. This frequency is fully supported across the full industrial temperature range (−40°C to +85°C) and ensures consistent instruction timing for hard real-time applications such as PLC scan cycles and CAN message scheduling.
Does the UPD70F3770GC-UEU-AX include a CAN controller?
Yes, the UPD70F3770GC-UEU-AX integrates a single CAN 2.0B-compliant controller supporting bit rates up to 1 Mbit/s, 32 message objects, and hardware-based acceptance filtering. It uses dedicated P00 (CAN_TX) and P01 (CAN_RX) pins and requires an external CAN transceiver such as the TJA1042 for physical layer interfacing.
What package type is used for the UPD70F3770GC-UEU-AX?
The UPD70F3770GC-UEU-AX is supplied in a 100-pin LQFP package measuring 14 mm × 14 mm with 0.5 mm lead pitch and an exposed thermal pad. This package is compatible with standard reflow profiles and supports high-density PCB layouts required in industrial control modules and railway interface units.
Is the UPD70F3770GC-UEU-AX qualified for automotive applications?
No, the UPD70F3770GC-UEU-AX is classified as a "Standard" quality grade device per Renesas documentation and is intended for industrial, office, and communications equipment-not transportation or safety-critical automotive systems. For automotive use, Renesas recommends AEC-Q100–qualified variants such as the RH850/F1L series instead of the UPD70F3770GC-UEU-AX.
What debug interface does the UPD70F3770GC-UEU-AX support?
The UPD70F3770GC-UEU-AX supports the IECUBE in-circuit emulator interface via dedicated JTAG pins (TCK, TMS, TDI, TDO, TRST). This enables full-speed real-time debugging, non-intrusive trace, and flash programming without requiring external debug probes beyond Renesas' QB-V850ESJX3H or compatible tools.
