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

For engineers reviewing the R5F526TFDGND#10 datasheet, R5F526TFDGND#10 pinout, R5F526TFDGND#10 application, or R5F526TFDGND#10 equivalent, key selection criteria include its 120 MHz GPTWa timer with 3-phase/5-phase complementary PWM support, dual-bank flash for safe firmware updates, hardware-accelerated trigonometric functions (TFUv2), and Trusted Secure IP Lite encryption engine with AES-128/256.

Technical Context

The R5F526TFDGND#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16-register bank save for fast context switching. Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator - enabling independent peripheral clock domains (PCLKA up to 120 MHz, PCLKB/C/D at lower ratios).

Motor control is enabled by tightly coupled peripherals: MTU3d (9-channel 16-bit timer) and GPTWa (8-channel 32-bit timer) both synchronized to PCLKC for precise PWM generation; HRPWM (4 channels) overlays sub-nanosecond timing control onto GPTW outputs; and ELC links A/D conversion triggers directly to timer events without CPU intervention.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TFDGND#10?

The R5F526TFDGND#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark points under benchmark conditions. This performance stems from the RXv3 CPU core's single-cycle instruction execution, 32-bit multiplier/divider, and barrel shifter - all confirmed in the R01DS0407EJ0120 Rev.1.20 datasheet. The R5F526TFDGND#10 sustains this speed across its 512 KB flash and 64 KB SRAM with zero wait states.

Does the R5F526TFDGND#10 support CAN FD, and what standard does it comply with?

Yes, the R5F526TFDGND#10 integrates a CAN FD module compliant with ISO11898-1:2015, supporting both standard and extended frames at data rates up to 5 Mbps. Its CTX0/CRX0 pins provide differential signaling compatible with industry-standard CAN transceivers. This capability is documented in Section 1.1 and Table 1.1 of the R01DS0407EJ0120 Rev.1.20 datasheet for the R5F526TFDGND#10.

What PWM resolution and channel count does the R5F526TFDGND#10 offer for motor control?

The R5F526TFDGND#10 provides three layered PWM resources: GPTWa (8×32-bit channels), MTU3d (9×16-bit channels), and HRPWM (4 channels). HRPWM delivers a minimum timing resolution of 260 ps when operating at 120 MHz - critical for SiC/GaN gate drive dead-time tuning. All PWM modules support complementary output modes with automatic dead-time insertion, as specified for the R5F526TFDGND#10 in the "Timers" section of R01DS0407EJ0120.

How does the R5F526TFDGND#10 support IEC60730 Class B compliance?

The R5F526TFDGND#10 includes dedicated hardware for IEC60730 Class B: oscillation-stop detection, RAM test assist via DOC, CRCA for data integrity, self-diagnostic A/D disconnection detection, and independent watchdog timer (IWDTa) with windowing. These features are explicitly listed in the "Useful functions for IEC60730 compliance" section of the R01DS0407EJ0120 Rev.1.20 datasheet for the R5F526TFDGND#10 and require no external components.

What package type and thermal characteristics apply to the R5F526TFDGND#10?

The R5F526TFDGND#10 uses the PLQP0100KB-B package: a 100-pin LFQFP with 14 × 14 mm body, 0.5 mm pitch, and exposed thermal pad. It is rated for –40°C to +85°C operation (D-version), with thermal resistance θJA ≈ 35°C/W typical. This package is validated for convection-cooled motor drive PCB layouts and supports reflow soldering per J-STD-020. Details appear in the "Package Information" section of R01DS0407EJ0120.
