It targets inverter-driven industrial motors, HVAC compressors, and servo drives requiring IEC 60730 functional safety support.

For engineers reviewing the R5F526TFCGNE#10 datasheet, R5F526TFCGNE#10 pinout, R5F526TFCGNE#10 application, or R5F526TFCGNE#10 equivalent, key selection criteria include its 100-pin LFQFP package, dual-bank flash for safe firmware updates, simultaneous sampling across three 12-bit ADC units, 3-phase complementary PWM generation with automatic dead-time insertion, and Trusted Secure IP Lite encryption for secure boot and key management.

Technical Context

The R5F526TFCGNE#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and collective register bank save for fast context switching. Its clock system integrates a PLL fed by an 8–24 MHz crystal or internal HOCO, enabling independent scaling of ICLK (up to 120 MHz), PCLKA (120 MHz), PCLKB (60 MHz), PCLKC (120 MHz), and PCLKD (60 MHz) for optimal peripheral timing.

Motor control is enabled by tightly coupled peripherals: MTU3d (9-channel 16-bit timer) and GPTWa (8-channel 32-bit timer) provide synchronized 3-phase PWM outputs with hardware dead-time compensation, while ELC links ADC conversion triggers directly to timer events without CPU intervention-enabling deterministic current-sampling in field-oriented control loops.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TFCGNE#10?

The R5F526TFCGNE#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance stems from its RXv3 CPU core with single-cycle instruction execution, on-chip FPU, and efficient memory subsystem - enabling real-time execution of complex motor control algorithms such as field-oriented control without external acceleration.

Does the R5F526TFCGNE#10 support IEC 60730 Class B compliance out of the box?

Yes, the R5F526TFCGNE#10 includes built-in hardware features required for IEC 60730 Class B certification: oscillation-stop detection, independent watchdog timer (IWDT) with windowed refresh, RAM test assistance via DOC, CRC calculator (CRCA), clock frequency accuracy measurement, and register write protection. These capabilities reduce software overhead and simplify safety certification for industrial and appliance applications.

How many ADC units does the R5F526TFCGNE#10 have, and what is their sampling capability?

The R5F526TFCGNE#10 includes three independent 12-bit ADC units (S12ADH): Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels), totaling 22 channels. It supports simultaneous sampling across all units using shared trigger sources, with minimum conversion time of 0.9 µs per channel at 60 MHz ADCLK - essential for synchronized current and voltage acquisition in 3-phase motor control.

What PWM resolution and channel configurations are supported by the R5F526TFCGNE#10?

The R5F526TFCGNE#10 supports 10 single-phase, 3 three-phase, or 2 five-phase complementary PWM outputs via its GPTWa and MTU3d timers. With the HRPWM module, it achieves a minimum timing resolution of 260 ps at 120 MHz - enabling precise gate timing for SiC and GaN power devices. Hardware dead-time insertion and non-overlapping waveform generation are fully autonomous.

Is the R5F526TFCGNE#10 pin-compatible with other RX26T group MCUs?

No, the R5F526TFCGNE#10 is not pin-compatible with other RX26T variants due to its 100-pin LFQFP (PLQP0100KB-B) package. Other members use 48-, 64-, 80-, or 32-pin packages with different pin counts and signal allocations. While functional compatibility exists within the RX26T family, PCB layout must be designed specifically for the 100-pin footprint and I/O mapping of R5F526TFCGNE#10.
