For engineers reviewing the R5F526TBAGFM#50 datasheet, R5F526TBAGFM#50 pinout, R5F526TBAGFM#50 application, or R5F526TBAGFM#50 equivalent, this MCU targets real-time motor drive systems requiring deterministic PWM timing, IEC60730-compliant safety features, simultaneous multi-channel A/D sampling, and secure firmware execution via Trusted Secure IP Lite encryption.

Technical Context

The R5F526TBAGFM#50 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 supports 8–24 MHz external crystal input to PLL, internal 240 kHz LOCO and selectable 16/18/20 MHz HOCO, and dedicated 120 kHz IWDT oscillator.

Peripheral timing is segmented across four clock domains: ICLK (up to 120 MHz for CPU), PCLKA (up to 120 MHz for MTU/GPTW/HRPWM/CAN FD), PCLKB (up to 60 MHz for SCI/RSCI/RIIC/RI3C), and PCLKD (up to 60 MHz for S12ADH A/D converter), enabling precise domain-specific frequency optimization without CPU intervention.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TBAGFM#50?

The R5F526TBAGFM#50 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, 32-bit multiplier/divider, and barrel shifter-enabling deterministic real-time response in motor control loops. The R5F526TBAGFM#50 sustains full 120 MHz operation across all memory and peripheral interfaces without wait states.

Does the R5F526TBAGFM#50 support CAN FD, and what standard does it comply with?

Yes, the R5F526TBAGFM#50 integrates a CAN FD module compliant with ISO11898-1:2015, supporting both standard and extended frames with data rates up to 5 Mbps in FD mode. It includes dedicated TX/RX pins, message RAM with configurable buffers, and error counters-enabling robust diagnostics and firmware updates over automotive or industrial CAN backbones. The R5F526TBAGFM#50 requires no external transceiver for physical layer compliance.

What PWM capabilities does the R5F526TBAGFM#50 offer for motor control applications?

The R5F526TBAGFM#50 provides 8-channel 32-bit GPTWa timers plus 4-channel HRPWM with 260 ps minimum resolution, supporting 10 single-phase, 3 three-phase, or 2 five-phase complementary PWM outputs. It includes automatic dead-time insertion, non-overlapping waveform generation, and ELC-synchronized A/D triggering-enabling precise vector control of PMSM, BLDC, and induction motors. The R5F526TBAGFM#50 delivers this functionality without external PWM generators or gate drivers.

How does the R5F526TBAGFM#50 support IEC60730 functional safety requirements?
