Product details
Overview
R5F526TBDDFM#30 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring 120 MHz operation, 512 KB code flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD, and high-resolution PWM with 260 ps timing resolution. It supports IEC60730 safety compliance and includes hardware encryption (AES-128/256), FPU, and dual-bank flash for safe firmware updates.
For engineers reviewing the R5F526TBDDFM#30 datasheet, R5F526TBDDFM#30 pinout, R5F526TBDDFM#30 application, or R5F526TBDDFM#30 equivalent, key selection considerations include its 100-pin LFQFP package, 3-phase/5-phase complementary PWM capability, simultaneous sampling across three 12-bit ADC units, and support for real-time event linking via ELC - all critical for high-fidelity motor phase control and embedded safety-critical systems.
Technical Context
The R5F526TBDDFM#30 implements the RXv3 CPU core with single-cycle instruction execution at 120 MHz, supporting IEEE 754-compliant single-precision FPU and collective 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 precise timing separation across ICLK (120 MHz), PCLKA (120 MHz), PCLKB (60 MHz), PCLKC (120 MHz), and PCLKD (60 MHz) domains.
Peripheral coordination is managed by the Event Link Controller (ELC), which interlinks 183 internal event signals - including MTU3d, GPTWa, and S12ADH triggers - without CPU intervention. Safety features include MPU, Trusted Memory (TM), register write protection, CRCA, oscillation-stop detection, and self-diagnostic A/D disconnection monitoring, all aligned to IEC60730 Class B requirements.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526TBDDFM#30?
The R5F526TBDDFM#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, and barrel shifter - all validated under full-speed operation with no wait states on its 512 KB on-chip flash. The R5F526TBDDFM#30 delivers deterministic real-time response essential for motor control loop closure within 1 µs.
Does the R5F526TBDDFM#30 support IEC60730 Class B compliance out of the box?
Yes, the R5F526TBDDFM#30 includes hardware features required for IEC60730 Class B compliance: memory protection unit (MPU), register write protection, CRCA for data integrity, oscillation-stop detection, self-diagnostic A/D disconnection monitoring, and RAM test assistance via DOC. These are documented in the R01DS0407EJ0120 datasheet and do not require external components. The R5F526TBDDFM#30 enables certified safety firmware implementation without adding discrete safety monitors.
What ADC configuration does the R5F526TBDDFM#30 provide, and how many channels support simultaneous sampling?
The R5F526TBDDFM#30 includes three independent 12-bit S12ADH units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels), totaling 22 configurable inputs. All three units support true simultaneous sampling - critical for capturing correlated motor phase currents and DC-link voltage in a single acquisition window. This capability is explicitly confirmed for R5F526TBDDFM#30 in Table 1.2 of R01DS0407EJ0120 and enables accurate field-oriented control without sampling skew.
What is the resolution and timing capability of the HRPWM in the R5F526TBDDFM#30?
The R5F526TBDDFM#30 integrates a 4-channel High-Resolution PWM (HRPWM) circuit capable of controlling rising/falling edges of GPTWa-generated waveforms with a minimum resolution of 260 ps at 120 MHz operation. This is achieved via dedicated fine-tuning logic synchronized to the PCLKC domain. The R5F526TBDDFM#30 uses this to achieve sub-nanosecond dead-time accuracy - directly reducing shoot-through risk and improving inverter efficiency in high-speed PMSM applications.
Which package and temperature grade does the R5F526TBDDFM#30 use?
The R5F526TBDDFM#30 uses the PLQP0100KB-B package: a 100-pin LFQFP with 14 × 14 mm body and 0.5 mm pitch. It is rated for the D-version industrial temperature range of –40°C to +85°C. This package provides 82 general-purpose I/O pins with 5-V tolerance, large-current drive capability on 15 pins, and dedicated MTU/GPTW output pins - matching the mechanical and thermal requirements of motor control PCB layouts specified in Renesas' RX26T hardware design guidelines.
