FAQ

What is the maximum operating frequency of the R5F72167ADFP#V1?

The R5F72167ADFP#V1 operates at a maximum CPU clock frequency of 120 MHz, achieved via its on-chip CPG with PLL. This frequency is fully supported across the industrial temperature range (−40°C to +85°C) with guaranteed timing margins per Renesas Hardware User's Manual Rev.4.00. The SH-2A core delivers dual-issue execution at this rate, enabling sub-10 ns instruction throughput for real-time control loops in the R5F72167ADFP#V1.

Does the R5F72167ADFP#V1 include an integrated USB physical layer?

Yes, the R5F72167ADFP#V1 integrates a full-speed USB 2.0 transceiver with on-die PHY circuitry, supporting both device and host modes. No external USB resistors or transceivers are required - USB_DP and USB_DM pins connect directly to the connector. This integration is confirmed in Section 4.8 of the SH7214/SH7216 Hardware User's Manual and reduces bill-of-materials cost and PCB area for HMI and firmware update interfaces using the R5F72167ADFP#V1.

How much on-chip Flash memory does the R5F72167ADFP#V1 provide?

The R5F72167ADFP#V1 includes 1 MB (1,048,576 bytes) of on-chip Flash memory, organized for single-cycle read access and rated for 100,000 write/erase cycles with data retention exceeding 20 years at 85°C. This capacity supports complex control firmware, bootloader, and parameter storage within a single R5F72167ADFP#V1 die - eliminating need for external non-volatile memory in most industrial applications.

Is the R5F72167ADFP#V1 pin-compatible with other SH7216 Series MCUs?

The R5F72167ADFP#V1 uses a 144-pin LQFP package shared across multiple SH7216 variants, but pin compatibility is not guaranteed across all functions. While power, clock, reset, and basic I/O pins align, peripheral signal assignments (e.g., USB, CAN, ADC channel mapping) differ between R5F72167ADFP#V1 and variants like R5F72165 or R5F72169. Always verify pin function tables in the Hardware User's Manual before substituting - the R5F72167ADFP#V1 has unique USB and CAN channel routing.

What development tools support the R5F72167ADFP#V1?

Renesas e² studio IDE with CS+ compiler toolchain fully supports the R5F72167ADFP#V1, including debug via E1/E20 emulators and Flash programming. Peripheral driver libraries (Renesas RA/SH Driver Package) and HAL APIs are provided for USB, CAN, ADC, and DTC modules. Reference schematics and layout guidelines for the R5F72167ADFP#V1 are published in Application Note R01AN1379JJ0100, covering clock stability, power decoupling, and USB signal integrity.
