Product details
Overview
R5F526T9BDNE#30 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring a 120 MHz CPU core, 512 KB on-chip code flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD interface, and hardware-accelerated 3-phase/5-phase complementary PWM generation with 260 ps timing resolution.
For engineers reviewing the R5F526T9BDNE#30 datasheet, R5F526T9BDNE#30 pinout, R5F526T9BDNE#30 application, or R5F526T9BDNE#30 equivalent, key selection criteria include its dual-bank flash architecture for safe firmware updates, IEC60730-compliant safety features (oscillation-stop detection, RAM test assist, CRC calculator), and dedicated HRPWM circuitry enabling precise gate drive timing in high-efficiency motor drives.
Technical Context
The R5F526T9BDNE#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16-register bank save capability-enabling deterministic real-time response in closed-loop motor control. Its clock system integrates PLL, 240-kHz LOCO, and 120-kHz IWDT-dedicated oscillator, with independent PCLKA/PCLKC domains allowing 120 MHz operation for GPTW/HRPWM while synchronizing ADCLK to PCLKD at up to 60 MHz.
Peripheral integration centers on motor control: MTU3d provides 9-channel 16-bit timers with dead-time compensation and 3-phase PWM output; GPTWa delivers 8-channel 32-bit PWM with synchronous start/stop and ELC-triggered A/D conversion; HRPWM refines GPTW0–GPTW3 outputs to 260 ps resolution. Safety is enforced via MPU, Trusted Memory (TM), register write protection, and CRCA for integrity checking.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526T9BDNE#30?
The R5F526T9BDNE#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This reflects its RXv3 CPU core's single-cycle instruction execution, efficient pipeline, and integrated FPU-enabling real-time execution of complex motor control algorithms such as field-oriented control (FOC) and sensorless estimation within tight timing budgets. The R5F526T9BDNE#30 sustains this performance with zero wait-state access to both 512 KB flash and 64 KB SRAM.
Does the R5F526T9BDNE#30 support IEC60730 Class B compliance out of the box?
Yes, the R5F526T9BDNE#30 includes dedicated hardware features required for IEC60730 Class B certification: oscillation-stop detection, A/D converter disconnection check, RAM test assist (DOC), CRC calculator (CRCA), memory protection unit (MPU), register write protection, and independent watchdog timer (IWDTa) with window function. These are documented in the R01DS0407EJ0120 datasheet and require no external components to implement basic self-test sequences-reducing certification effort for R5F526T9BDNE#30-based motor controllers.
What PWM configurations does the R5F526T9BDNE#30 support, and how is HRPWM used?
The R5F526T9BDNE#30 supports 10-channel single-phase, 3-channel 3-phase, and 2-channel 5-phase complementary PWM via MTU3d and GPTWa. Its 4-channel HRPWM circuit refines GPTW0–GPTW3 outputs with a minimum timing resolution of 260 ps at 120 MHz-used to adjust rising/falling edge timing independently for precise dead-time control in SiC or fast IGBT gate drivers. This capability is exclusive to the R5F526T9BDNE#30 within the RX26T family and is not available on lower-pin-count variants like R5F526TADNFP#30.
What is the flash and SRAM capacity of the R5F526T9BDNE#30, and does it support background programming?
The R5F526T9BDNE#30 integrates 512 KB of on-chip code flash memory and 64 KB of SRAM, both accessible at 120 MHz with zero wait states. It supports background programming and erasing (BGO) for both code flash and 16 KB data flash-allowing firmware updates or parameter writes while the CPU executes application code. Its dual-bank flash structure further enables safe startup bank switching, critical for fail-safe firmware recovery in R5F526T9BDNE#30-based industrial drives.
Which package and temperature grade does the R5F526T9BDNE#30 use?
The R5F526T9BDNE#30 uses the PLQP0100KB-B package: a 100-pin LQFP with 14 × 14 mm body size, 0.5 mm lead pitch, and exposed thermal pad. It is rated for the D-version industrial temperature range of –40°C to +85°C, making it suitable for deployment in motor control enclosures, HVAC systems, and factory automation equipment where ambient thermal stress is present. This package provides sufficient I/O (82 GPIO) and thermal dissipation for sustained 120 MHz operation.
