It supports IEC60730 safety compliance and operates across –40°C to +85°C.

For engineers reviewing the R5F526T9BDFP#50 datasheet, R5F526T9BDFP#50 pinout, R5F526T9BDFP#50 application, or R5F526T9BDFP#50 equivalent, key selection criteria include its 120 MHz GPTWa timer with 10-channel single-phase complementary PWM, 260 ps HRPWM timing resolution, dual-bank flash for safe firmware updates, Trusted Secure IP Lite encryption, and 83-pin PLQP0100KB-B package with 5-V tolerant I/Os.

Technical Context

The R5F526T9BDFP#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-critical for real-time motor control loops. Its clock system integrates PLL, 240-kHz LOCO, and 120-kHz IWDT-dedicated oscillator, enabling independent domain clocking (ICLK up to 120 MHz, PCLKA up to 120 MHz, PCLKC up to 120 MHz) for precise peripheral synchronization.

Peripheral integration centers on deterministic timing: MTU3d and GPTWa timers operate on PCLKC for sub-nanosecond PWM edge placement, while ELC enables interrupt-free inter-module triggering (e.g., MTU event → A/D conversion start), and POE3D/POEG circuits provide hardware-level output disable during overcurrent or comparator fault detection-eliminating software latency in protection responses.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526T9BDFP#50?

The R5F526T9BDFP#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 execution of motor control algorithms. The R5F526T9BDFP#50 sustains this speed across its 512 KB flash and 64 KB SRAM with no wait states, critical for real-time FOC loops.

Does the R5F526T9BDFP#50 support CAN FD, and what standard does it comply with?

Yes, the R5F526T9BDFP#50 integrates a CAN FD module compliant with ISO11898-1:2015 for both standard and extended frames. It supports data rates up to 5 Mbps in the FD phase and includes built-in message filtering, FIFO buffering, and error handling-enabling robust communication in motor control networks. The R5F526T9BDFP#50 requires an external CAN transceiver (e.g., TJA1044) for physical layer implementation.

What PWM capabilities does the R5F526T9BDFP#50 offer for 3-phase inverter control?

The R5F526T9BDFP#50 delivers hardware-optimized 3-phase PWM via MTU3d (9-channel 16-bit) and GPTWa (8-channel 32-bit), supporting complementary output with automatic dead-time insertion, synchronous update, and phase-counting mode. Its 4-channel HRPWM achieves 260 ps minimum edge resolution at 120 MHz-enabling precise timing for SiC/GaN gate drivers. The R5F526T9BDFP#50 also includes POE3D circuitry for hardware-triggered output disable during overcurrent faults.

How does the R5F526T9BDFP#50 support IEC60730 Class B compliance?

The R5F526T9BDFP#50 includes dedicated hardware for IEC60730 Class B: oscillation-stop detection, RAM test assist (DOC), CRCA for data integrity, register write protection, self-diagnostic A/D functions, and analog input disconnection detection. These features are documented in Renesas' R01DS0407EJ0120 datasheet and supported by application notes AN2701 and AN2702. The R5F526T9BDFP#50 requires proper configuration per these guides to achieve certified compliance.

What is the package type and pin count of the R5F526T9BDFP#50?

The R5F526T9BDFP#50 uses the PLQP0100KB-B package: a 100-pin low-profile quad flat package with 14 mm × 14 mm body size, 0.5 mm lead pitch, and exposed thermal pad. It provides 83 general-purpose I/O pins-including 2 × 5-V tolerant inputs-along with dedicated motor control peripherals (MTU, GPTW, HRPWM). This package is pin-compatible with other RX26T 100-pin variants like R5F526TADFP#50.
