FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TFDGNE#10?

The R5F526TFDGNE#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency, including single-cycle instruction execution, hardware FPU, and optimized memory subsystem - enabling real-time motor control loop execution within strict timing budgets. The R5F526TFDGNE#10 sustains this performance with no wait states on its 512 KB code flash and 64 KB SRAM.

Does the R5F526TFDGNE#10 support IEC60730 Class B compliance out of the box?

Yes, the R5F526TFDGNE#10 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stop detection, RAM test-assisting function via DOC, CRCA for data integrity, independent watchdog timer (IWDTa) with windowing, analog comparator disconnection detection, and register write protection. These are documented in the R01DS0407EJ0120 datasheet and require no external components to implement basic self-test routines - simplifying certification for R5F526TFDGNE#10-based motor controllers.

How many A/D converter units does the R5F526TFDGNE#10 have, and what is their sampling capability?

The R5F526TFDGNE#10 integrates three independent 12-bit S12ADH A/D converter units: Unit 0 (4 channels with 3 sample-and-hold circuits), Unit 1 (4 channels with 3 sample-and-hold circuits), and Unit 2 (14 channels). This configuration enables true simultaneous sampling across all three units - critical for accurate current/voltage measurement in multi-phase motor control. Minimum conversion time is 0.9 µs per channel when ADCLK runs at 60 MHz.

What PWM modes and channel counts are supported by the R5F526TFDGNE#10?

The R5F526TFDGNE#10 supports single-phase complementary (10 channels), 3-phase complementary (3 channels), and 5-phase complementary (2 channels) PWM via its eight 32-bit GPTWa timers. Additionally, it provides four HRPWM channels synchronized to GPTW outputs with 260 ps minimum edge resolution. All PWM outputs support programmable dead time, synchronous start/stop, and fault protection via POE3D and POEG modules - directly addressing SiC/GaN inverter gate drive requirements.

Is CAN FD supported on the R5F526TFDGNE#10, and what standard does it comply with?

Yes, the R5F526TFDGNE#10 includes one CAN FD module compliant with ISO 11898-1:2015, supporting both standard (11-bit) and extended (29-bit) frame formats. It enables data rates up to 5 Mbps in the flexible data-rate phase, with built-in message filtering, FIFO buffering, and error handling. This allows R5F526TFDGNE#10-based systems to replace legacy CAN 2.0B nodes in automotive EPS and industrial networks while maintaining backward compatibility.
