FAQ

What is the maximum operating frequency of the UPD70F3913GF(R)-GAS-AX?

The UPD70F3913GF(R)-GAS-AX supports a maximum CPU clock frequency of 64 MHz, achieved via its on-chip PLL configured for multiplication of an external 1–20 MHz crystal or resonator input. This frequency is sustained across the full industrial temperature range (−40°C to +85°C) and supply voltage range (2.7–5.5 V), as confirmed in Section 5.4 and Table 28.1 of the Renesas Hardware User's Manual Rev.3.00.

Does the UPD70F3913GF(R)-GAS-AX include a CAN controller?

Yes, the UPD70F3913GF(R)-GAS-AX integrates a full CAN 2.0B controller compliant with ISO 11898-1, supporting bit rates up to 1 Mbps, 32 message objects, automatic retransmission, and bus-off recovery. Its CANTX/CANRX pins require an external physical-layer transceiver, and the controller is accessible via dedicated registers documented in Chapter 12 of the Hardware User's Manual.

What package type and pin count does the UPD70F3913GF(R)-GAS-AX use?

The UPD70F3913GF(R)-GAS-AX uses a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad, matching the V850E/IG4-H standard footprint. Pin configuration is fully detailed in Section 1.5.1 of the Renesas Hardware User's Manual Rev.3.00, and the part number suffix "-GAS-AX" explicitly denotes this package variant.

Is the UPD70F3913GF(R)-GAS-AX pin-compatible with other V850E/IG4-H MCUs?

Yes, the UPD70F3913GF(R)-GAS-AX shares identical pinout and electrical characteristics with other V850E/IG4-H family members including μPD70F3919, μPD70F3920, and μPD70F3921, as confirmed in Section 1.4.1 and Figure 1.1 of the Hardware User's Manual. This allows drop-in replacement within the same package variant for design flexibility and BOM optimization.

What development tools are supported for the UPD70F3913GF(R)-GAS-AX?

The UPD70F3913GF(R)-GAS-AX is supported by Renesas' QB-MINI2 on-chip debug emulator, CA850 C compiler, ID850QB integrated debugger, and PG-FP5 flash programmer. These tools enable full-cycle development - from C-language coding and real-time debugging to Flash programming - as listed in the "Related Documents" section of the Hardware User's Manual Rev.3.00.
