FAQ

What is the maximum operating frequency of the M30290FCVHP#U7A?

The M30290FCVHP#U7A operates at a maximum CPU clock frequency of 20 MHz. This is achieved using the on-chip PLL to multiply an external main clock input (1–10 MHz). The PLL supports selectable multiplication factors (×1 to ×4), and the resulting clock feeds both the CPU core and peripheral function clocks (f1, f2, f8, etc.) with configurable dividers. All timing specifications in the hardware manual assume operation within this 20 MHz limit.

Does the M30290FCVHP#U7A include an integrated CAN transceiver?

No, the M30290FCVHP#U7A includes only a CAN protocol controller compliant with ISO 11898-1 (CAN 2.0B), not a physical-layer transceiver. It provides CANH and CANL differential signal pins that must be connected to an external CAN transceiver (e.g., TJA1042 or SN65HVD230) to interface with the bus. The controller handles message framing, arbitration, error detection, and automatic retransmission-but level-shifting and bus driving require external components.

What package type and pin count does the M30290FCVHP#U7A use?

The M30290FCVHP#U7A uses a 100-pin LQFP (Low-Profile Quad Flat Package) with 0.5 mm pitch and an exposed thermal pad (EP). Its dimensions are 14 mm × 14 mm. This package is standardized across the M16C/29 Group and supports full I/O access, including all 16 port groups, dual clock inputs, CANH/CANL, reset, and power/ground pins. The EP improves thermal performance in continuous motor control operation.

Can the M30290FCVHP#U7A operate from a single 3.3 V supply?

Yes, the M30290FCVHP#U7A supports operation from a single 3.3 V supply within its specified range of 2.7 V to 5.5 V. At 3.3 V, it maintains full functionality-including 20 MHz CPU operation, CAN controller, 12-bit ADC, and MTU-with guaranteed timing and electrical characteristics per the Renesas hardware manual. Internal voltage regulation ensures stable core logic voltage regardless of I/O rail level, allowing mixed-voltage interfacing with 3.3 V peripherals.

Is the M30290FCVHP#U7A qualified for automotive applications?

The M30290FCVHP#U7A is classified as a "Standard" quality grade device per Renesas' product grading system and is not specifically qualified for automotive applications. While it supports CAN 2.0B and operates across industrial temperature ranges (−40°C to +85°C), it lacks AEC-Q100 qualification, automotive-specific reliability testing, and extended temperature grade (−40°C to +125°C). For automotive body control modules, Renesas recommends AEC-Q100-qualified alternatives such as the RL78/F14 or RH850/F1L series.
