Renesas R5F526TBDDFN#30

Overview

R5F526TBDDFN#30 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, operating at up to 120 MHz with 709 CoreMark performance, 256 KB on-chip code flash, 48 KB SRAM, and integrated 12-bit A/D converter (7+8 channels), 6-channel analog comparator, and CAN FD interface compliant with ISO 11898-1:2015.

For engineers reviewing the R5F526TBDDFN#30 datasheet, R5F526TBDDFN#30 pinout, R5F526TBDDFN#30 application, or R5F526TBDDFN#30 equivalent, key selection criteria include its 120-MHz GPTW/MTU3 timer subsystem for 3-phase complementary PWM generation, HRPWM with 260-ps timing resolution, dual-bank flash for safe firmware updates, and IEC60730-compliant safety features including oscillation-stop detection and RAM test assistance.

Technical Context

The R5F526TBDDFN#30 implements the RXv3 CPU core with single-cycle instruction execution, 32-bit multiplier/divider, and optional single-precision FPU. It supports little-endian data and IEEE 754-compliant floating-point arithmetic. Its memory protection unit (MPU) enforces eight configurable protection regions of minimum 16-byte granularity.

Timing is managed via a multi-clock domain architecture: ICLK up to 120 MHz for CPU and bus masters; PCLKA up to 120 MHz for MTU/GPTW/HRPWM; PCLKB up to 60 MHz for most peripherals; PCLKC up to 120 MHz for counter reference clocks; and PCLKD up to 60 MHz for ADC clocking. The ELC enables interrupt-free inter-module event linking across sleep modes.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TBDDFN#30?

The R5F526TBDDFN#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance under benchmark conditions. This reflects its RXv3 CPU core efficiency, including single-cycle instruction execution, 32-bit multiplier/divider, and optimized pipeline design-enabling deterministic real-time response in motor control loops without software throttling.

Does the R5F526TBDDFN#30 support CAN FD, and what standard does it comply with?

Yes, the R5F526TBDDFN#30 integrates one CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames. It enables data rates up to 5 Mbps in the data phase, making it suitable for high-bandwidth communication in industrial automation networks and EV subsystems where legacy CAN 2.0B bandwidth is insufficient.

What ADC configuration does the R5F526TBDDFN#30 provide, and how many channels are available?

The R5F526TBDDFN#30 includes a 12-bit S12ADH ADC with two units: Unit 0 (7 channels with 3-sample-and-hold circuits) and Unit 2 (8 channels). This configuration supports simultaneous sampling across multiple motor current and voltage sensing paths-critical for accurate field-oriented control in 3-phase inverter systems.

What package type and thermal characteristics does the R5F526TBDDFN#30 use?

The R5F526TBDDFN#30 uses the PWQN0048KC-A package: a 48-pin HWQFN, 7 mm × 7 mm, 0.5 mm pitch, with exposed thermal pad. It is rated for –40°C to +85°C operation (D-version), and its thermal design supports sustained 120 MHz operation in compact industrial enclosures with moderate airflow.

How does the R5F526TBDDFN#30 support IEC60730 Class B compliance?

The R5F526TBDDFN#30 includes hardware-assisted IEC60730 Class B features: oscillation-stop detection, self-diagnostic ADC, clock frequency accuracy measurement, independent watchdog timer (IWDTa), RAM test assistance via DOC, and register write protection. These reduce software validation burden and accelerate certification for household and industrial appliances.
