For engineers reviewing the R5F526T9BGFP#50 datasheet, R5F526T9BGFP#50 pinout, R5F526T9BGFP#50 application, or R5F526T9BGFP#50 equivalent, key selection considerations include its 100-pin LFQFP package, 3-phase/5-phase complementary PWM capability, 120 MHz GPTWa timer operation, integrated HRPWM for sub-nanosecond dead-time control, and support for real-time event linking via ELC without CPU intervention.

Technical Context

The R5F526T9BGFP#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 integrates PLL with external 8–24 MHz crystal reference, internal HOCO (16/18/20 MHz), and dedicated 120 kHz IWDT oscillator - all supporting independent domain clocks (ICLK up to 120 MHz, PCLKA up to 120 MHz, PCLKB up to 60 MHz).

Peripheral architecture centers on deterministic real-time control: MTU3d provides 9-channel 16-bit timers with 3-phase complementary PWM and automatic dead-time insertion; GPTWa offers 8-channel 32-bit PWM with synchronous start/stop and ELC-triggered A/D conversion; HRPWM achieves 260 ps resolution on GPTW0–GPTW3 outputs; and S12ADH includes three 12-bit A/D units (4+4+14 channels) with sample-and-hold and self-diagnostic functions.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526T9BGFP#50?

The R5F526T9BGFP#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, on-chip FPU, and optimized memory subsystem enabling no-wait access to both 512 KB flash and 64 KB SRAM at full speed. The R5F526T9BGFP#50 delivers deterministic real-time response essential for motor control loops.

Does the R5F526T9BGFP#50 support CAN FD, and what standard does it comply with?

Yes, the R5F526T9BGFP#50 integrates one CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames with bit rates up to 5 Mbps in the data phase. It includes built-in message filtering, FIFO buffering, and error counters - enabling robust communication in industrial networks and automotive subsystems. The R5F526T9BGFP#50 uses dedicated CANH/CANL pins with bus fault detection capability.

What PWM resolution and complementary output capabilities does the R5F526T9BGFP#50 provide?

The R5F526T9BGFP#50 provides 10-channel single-phase, 3-channel 3-phase, and 2-channel 5-phase complementary PWM via its GPTWa and MTU3d timers, plus 4-channel High-Resolution PWM (HRPWM) with a minimum timing resolution of 260 ps at 120 MHz. This enables precise dead-time control for SiC/GaN gate drivers. The R5F526T9BGFP#50 supports automatic dead-time insertion, non-overlapping waveform generation, and synchronous start/stop across multiple channels.

How many A/D converter channels does the R5F526T9BGFP#50 have, and do they support simultaneous sampling?

The R5F526T9BGFP#50 includes three 12-bit S12ADH A/D units totaling 22 channels: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels). All units support simultaneous sampling triggered by a common event signal - critical for capturing correlated current/voltage feedback in motor control. Conversion time is as low as 0.9 µs per channel when ADCLK runs at 60 MHz. The R5F526T9BGFP#50 also integrates sample-and-hold circuits on Units 0 and 1.

What safety and security features are integrated into the R5F526T9BGFP#50 for IEC 60730 compliance?

The R5F526T9BGFP#50 integrates multiple IEC 60730 Class B support features: oscillation-stop detection for main clock, RAM test assist via DOC, CRCA hardware CRC engine, analog comparator disconnection detection, and register write protection. It also includes Trusted Memory (TM) to prevent code readout and an MPU with eight configurable protection regions. These features reduce external component count and simplify certification for R5F526T9BGFP#50-based safety-critical motor controllers.
