FAQ

What is the maximum operating frequency of the UPD70F3371M2GBA1-GAH-AX?

The UPD70F3371M2GBA1-GAH-AX operates at a maximum frequency of 40 MHz when powered within its specified 1.8–5.5 V supply range and using the internal PLL with appropriate external crystal or clock source. This frequency is confirmed in Section 4.4.6 of Renesas document R01UH0237ED0320 Rev. 3.20, which details PLL configuration limits and startup timing constraints for the V850ES/Fx3 series.

Does the UPD70F3371M2GBA1-GAH-AX include a CAN interface?

Yes, the UPD70F3371M2GBA1-GAH-AX integrates a CAN 2.0B-compliant controller with dedicated TXD_CAN and RXD_CAN pins. It supports bit rates up to 1 Mbps and includes message objects, error counters, and loopback self-test mode. As stated in Chapter 1.2 (Features Summary) and Section 2.5.18 (Port group CT) of R01UH0237ED0320 Rev. 3.20, the CAN peripheral is fully functional within the UPD70F3371 variant.

What package type is used for the UPD70F3371M2GBA1-GAH-AX?

The UPD70F3371M2GBA1-GAH-AX uses a 144-pin LQFP package (20 mm × 20 mm, 0.5 mm pitch), designated as "M2G" in Renesas ordering nomenclature.
