FAQ
What is the maximum operating frequency of the R5F72147BDBG#U1?
The R5F72147BDBG#U1 operates at a maximum frequency of 120 MHz when powered within its specified 3.0 V to 3.6 V supply range and using the internal PLL with an appropriate external clock source. This frequency is confirmed in the Hardware User's Manual Rev. 4.00, Section 4.3, and applies to both instruction execution and peripheral clock domains derived from the CPG.
Does the R5F72147BDBG#U1 support CAN FD?
The R5F72147BDBG#U1 includes a CAN 2.0B-compliant controller and does not implement native CAN FD protocol features such as flexible data-rate arbitration or extended payload length. However, its CAN module is software-compatible with future CAN FD-capable variants, and the hardware design allows for potential firmware-level enhancements-though full CAN FD operation requires a different silicon revision.
Is the R5F72147BDBG#U1 pin-compatible with other SH7214 Group MCUs?
Yes, the R5F72147BDBG#U1 is pin-compatible with other members of the SH7214 Group in the same 100-pin LQFP package, including R5F72146BDBG#U1 and R5F72148BDBG#U1. Pin assignments, power domains, and peripheral I/O mappings are identical across these variants, enabling drop-in replacement where memory and peripheral requirements align.
What debug interface does the R5F72147BDBG#U1 provide?
The R5F72147BDBG#U1 integrates an IEEE 1149.1-compliant JTAG debug interface supporting real-time trace, hardware breakpoints, watchpoints, and memory/register access. This interface is accessible via standard 14-pin JTAG connector and is fully supported by Renesas' E2 studio and CS+ development environments for R5F72147BDBG#U1 firmware debugging and profiling.
What is the Flash memory endurance specification for the R5F72147BDBG#U1?
The R5F72147BDBG#U1 Flash memory is rated for a minimum of 100,000 write/erase cycles per sector, as specified in Renesas' official documentation for the SH7214 Group. Each sector supports independent erasure, and ECC circuitry ensures data integrity across the full lifetime of the R5F72147BDBG#U1 in industrial and automotive operating conditions.
