For engineers reviewing the R5F526TFDDFL#30 datasheet, R5F526TFDDFL#30 pinout, R5F526TFDDFL#30 application, or R5F526TFDDFL#30 equivalent, key selection criteria include its 120-MHz GPTWa timer with 3-phase/5-phase complementary PWM support, simultaneous sampling across three 12-bit A/D units, IEC60730 safety features including oscillation-stop detection and RAM test assistance, and Trusted Secure IP Lite encryption with AES-128/256.

Technical Context

The R5F526TFDDFL#30 implements the RXv3 CPU core with single-cycle instruction execution, 113 instructions (including 11 FP and 23 DSP ops), and collective register bank save for fast context switching. Its clock system integrates PLL with 8–24 MHz crystal input, 240-kHz LOCO, and 120-kHz IWDT-dedicated oscillator - enabling independent timing domains for ICLK (120 MHz), PCLKA (120 MHz), PCLKB (60 MHz), PCLKC (120 MHz), and PCLKD (60 MHz).

Peripheral coordination is managed via Event Link Controller (ELC) supporting 183 internal event signals, allowing module-triggered operation without CPU intervention. Safety-critical functions include MPU with eight configurable protection areas, Trusted Memory (TM) for code flash read protection, register write protection, CRCA for CRC-8/32, and dedicated self-test circuits for A/D disconnection, clock accuracy, and RAM integrity per IEC60730 Class B requirements.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TFDDFL#30?

The R5F526TFDDFL#30 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, barrel shifter, and 113-instruction set including 11 floating-point and 23 DSP operations - all validated in the official Renesas R01DS0407EJ0120 datasheet.

Does the R5F526TFDDFL#30 support IEC60730 Class B compliance out of the box?

Yes, the R5F526TFDDFL#30 includes multiple hardware features required for IEC60730 Class B certification: oscillation-stop detection for main clock, self-diagnostic A/D disconnection check, independent watchdog timer (IWDT) with window function, CRC calculator (CRCA), memory protection unit (MPU), register write protection, and RAM test assistance via DOC. These are documented in Section 1.1 and safety feature tables of the R01DS0407EJ0120 datasheet.

What is the resolution and capability of the high-resolution PWM (HRPWM) in the R5F526TFDDFL#30?

The R5F526TFDDFL#30 features 4-channel HRPWM capable of 260 ps minimum resolution when operating at 120 MHz - applied to GPTW0 through GPTW3 outputs. This enables sub-nanosecond dead-time control for SiC/GaN gate drivers. The HRPWM works in conjunction with the 32-bit GPTWa timers and is explicitly specified in Table 1.1 and Section 1.1 "High-resolution PWM waveform generation circuit" of the R01DS0407EJ0120 datasheet.

How many A/D converter units does the R5F526TFDDFL#30 have, and what is their sampling configuration?

The R5F526TFDDFL#30 includes three independent 12-bit S12ADH units: Unit 0 (4 channels, 3 sample-and-hold circuits), Unit 1 (4 channels, 3 sample-and-hold circuits), and Unit 2 (14 channels). This allows true simultaneous sampling across up to 22 channels - confirmed in Table 1.1 and Section 1.1 "12-bit A/D converter (S12ADH)" of the R01DS0407EJ0120 datasheet for devices with 64 KB SRAM.

What communication interfaces are supported by the R5F526TFDDFL#30, and which support ELC triggering?

The R5F526TFDDFL#30 supports CAN FD (1 channel), RIICa (I²C/SMBus), RI3C (I3C SDR), RSPId (SPI, 30 Mbps), RSPIA (TI SSP), 4× SCI, and 3× RSCI with Manchester encoding. ELC triggering is supported by CANFD, RIICa, RI3C, RSPId, RSPIA, SCI5, RSCI11, MTU3d, GPTWa, S12ADH, and CMPCa - as listed in Section 1.1 "Event link controller (ELC)" and peripheral-specific subsections of the R01DS0407EJ0120 datasheet.
