FAQ

What is the maximum operating frequency of the R5F72867N100FA#U2?

The R5F72867N100FA#U2 operates at a maximum frequency of 100 MHz. This speed is achieved using the on-chip PLL-based Clock Pulse Generator (CPG), which multiplies an external crystal input (1–20 MHz) to generate the system clock. The 100 MHz rating applies across the full -40°C to +105°C temperature range and 3.0–3.6 V supply voltage, as verified in Renesas' electrical characteristics tables.

Does the R5F72867N100FA#U2 include an integrated USB transceiver?

Yes, the R5F72867N100FA#U2 integrates a full-speed USB 2.0 transceiver (PHY) compliant with USB specification revision 2.0. It supports both host and device modes without requiring external PHY components. The USB interface uses dedicated VDD/USB_VSS pins and includes internal termination resistors, enabling direct connection to USB connectors with appropriate ESD protection.

What package type and pin count does the R5F72867N100FA#U2 use?

The R5F72867N100FA#U2 is housed in a 100-pin LQFP package measuring 14 mm × 14 mm with 0.5 mm lead pitch. This package is RoHS-compliant and rated for moisture sensitivity level MSL3. Pin assignments-including dedicated USB, CAN, ADC, and MTU2S timer I/O-are fully documented in Section 1.3 (Pin Assignment) and Section 1.4 (Pin Functions) of the SH7280 Group Hardware User's Manual.
