FAQ

What is the maximum operating frequency of the R5F72867D100FP#U2?

The R5F72867D100FP#U2 operates at a maximum CPU frequency of 100 MHz using its internal PLL with an external 4–20 MHz crystal. This frequency is sustained across the full industrial temperature range (−40°C to +85°C) under 3.3 V ±0.3 V supply conditions, as verified in the DC characteristics section of the hardware manual. The R5F72867D100FP#U2 achieves this performance without requiring external frequency multipliers or auxiliary clock conditioning circuits.

Does the R5F72867D100FP#U2 include an integrated USB transceiver?

Yes, the R5F72867D100FP#U2 integrates a full-speed USB 2.0 device transceiver with internal termination and a 1.5 kΩ pull-up resistor on USB_DP. This eliminates the need for an external PHY in standard USB device implementations. The R5F72867D100FP#U2 supports descriptor-based enumeration and endpoint management via its on-chip USB controller, enabling direct connection to host systems without additional silicon.

How many CAN interfaces does the R5F72867D100FP#U2 support?

The R5F72867D100FP#U2 supports two independent CAN 2.0B controllers, each with dedicated message RAM, acceptance filtering, and error counters. Both controllers operate concurrently at baud rates up to 1 Mbps and are electrically isolated from each other - requiring separate external CAN transceivers. This dual-CAN capability is confirmed in the peripheral overview and register map sections of the SH7280 Group hardware manual for R5F72867D100FP#U2.

What is the Flash memory capacity of the R5F72867D100FP#U2?

The R5F72867D100FP#U2 includes 1 MB of on-chip Flash memory organized in 128-byte programmable sectors, supporting erase/write operations under software control. This capacity accommodates complex real-time firmware with bootloader, application, and parameter storage partitions. The R5F72867D100FP#U2 Flash meets AEC-Q100 Grade 2 requirements for endurance (100,000 write/erase cycles) and data retention (20 years at 85°C), as specified in Renesas' product documentation.

Is the R5F72867D100FP#U2 pin-compatible with other SH7280 Group MCUs?

Yes, the R5F72867D100FP#U2 is fully pin-compatible with other 100-pin LQFP variants in the SH7280 Group, including R5F72865D100FP#U2 and R5F72868D100FP#U2. All share identical pin assignments, electrical characteristics, and mechanical footprint - enabling drop-in replacement within the same package variant. This compatibility is explicitly documented in Section 1.3 (Pin Assignment) and Section 1.4 (Pin Functions) of the SH7280 Group hardware manual for R5F72867D100FP#U2.
