For engineers reviewing the R5F526T9BDFP#30 datasheet, R5F526T9BDFP#30 pinout, R5F526T9BDFP#30 application, or R5F526T9BDFP#30 equivalent, key selection considerations include its 100-pin LFQFP package with 82 general-purpose I/Os (2 × 5-V tolerant), 260 ps high-resolution PWM timing resolution, simultaneous sampling across three 12-bit A/D units, and Trusted Secure IP Lite encryption support for IEC 60730-compliant safety-critical firmware.

Technical Context

The R5F526T9BDFP#30 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 an 8–24 MHz external crystal oscillator, 240 kHz LOCO, 16/18/20 MHz HOCO, and PLL for 120 MHz system clock generation with independent PCLKA/PCLKB/PCLKC/PCLKD domains enabling mixed-speed peripheral operation.

Motor control functionality is anchored by the GPTWa (8-channel 32-bit timer), MTU3d (9-channel 16-bit timer), and HRPWM (4-channel high-resolution PWM) modules, all synchronized to PCLKC up to 120 MHz and supporting dead-time insertion, phase-counting, and ELC-triggered A/D conversion start. The S12ADH ADC includes three sample-and-hold units enabling true simultaneous sampling of up to 22 analog channels.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526T9BDFP#30?

The R5F526T9BDFP#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, on-chip FPU, and optimized memory subsystem enabling no-wait access to both 512 KB code flash and 64 KB SRAM at full speed. The R5F526T9BDFP#30 maintains this rating under industrial temperature conditions (–40°C to +85°C).

Does the R5F526T9BDFP#30 support CAN FD, and what standard does it comply with?

Yes, the R5F526T9BDFP#30 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frame formats with flexible data-rate capability. It operates as a single-channel CAN FD controller with built-in message RAM, filtering, and error handling-enabling high-bandwidth diagnostics and control messaging in automotive and industrial networks. The R5F526T9BDFP#30 requires external CAN transceivers for physical layer interfacing.

How many analog-to-digital converter channels does the R5F526T9BDFP#30 support, and what sampling capability does it offer?

The R5F526T9BDFP#30 includes three 12-bit S12ADH ADC units supporting up to 22 total input channels: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels). Critically, it provides true simultaneous sampling across all three units using dedicated sample-and-hold circuits-enabling synchronized current, voltage, and temperature acquisition essential for vector control algorithms. The R5F526T9BDFP#30 achieves 0.9 µs minimum conversion time per channel when ADCLK runs at 60 MHz.

What PWM resolution and output configurations are available on the R5F526T9BDFP#30?

The R5F526T9BDFP#30 supports multiple PWM modes: 10 single-phase, 3 three-phase, or 2 five-phase complementary outputs via its GPTWa and MTU3d timers. Its HRPWM module delivers 260 ps minimum timing resolution on GPTW0–GPTW3 outputs-critical for minimizing dead-time uncertainty in SiC/GaN-based inverters. All PWM channels support programmable dead-time insertion, synchronous start/stop, and ELC-triggered A/D conversion initiation. The R5F526T9BDFP#30 also includes POE3D and POEG modules for hardware-controlled output disable during fault conditions.

Is the R5F526T9BDFP#30 qualified for functional safety standards such as IEC 60730?

Yes, the R5F526T9BDFP#30 includes dedicated hardware features for IEC 60730 Class B compliance: oscillation-stoppage detection, RAM test assist via DOC, CRC calculator (CRCA), register write protection, and self-diagnostic functions for the A/D converter and clock accuracy measurement. These capabilities are documented in Renesas' Functional Safety Manual for the RX26T Group and validated per IEC 60730-1 Annex H. The R5F526T9BDFP#30 does not require external safety monitors to meet basic Class B requirements.
