Product details
Overview
R5F526T9BGFM#10 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring 120 MHz operation, 512 KB on-chip flash, 64 KB SRAM, 16 KB data flash, CAN FD interface, and integrated high-resolution PWM with 260 ps timing resolution. It supports IEC60730 safety compliance and includes Trusted Secure IP Lite encryption.
For engineers reviewing the R5F526T9BGFM#10 datasheet, R5F526T9BGFM#10 pinout, R5F526T9BGFM#10 application, or R5F526T9BGFM#10 equivalent, key selection considerations include its 100-pin LFQFP package, dual-bank flash for safe firmware updates, simultaneous sampling across three 12-bit ADC units, and hardware-accelerated trigonometric functions (TFUv2) for real-time field-oriented control.
Technical Context
The R5F526T9BGFM#10 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 PLL, HOCO/LOCO oscillators, and independent IWDT-dedicated 120 kHz oscillator - all supporting precise timing for motor phase control and safety monitoring.
Peripheral coordination is managed via the Event Link Controller (ELC), enabling 183 internal event signals to trigger timer starts, ADC conversions, or PWM dead-time adjustments without CPU intervention. The GPTWa timer (8-channel, 32-bit) and MTU3d (9-channel, 16-bit) operate synchronously at up to 120 MHz on PCLKA/PCLKC, while HRPWM achieves 260 ps resolution by fine-tuning GPTW output edges.

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F526TADFM#30 | Same RX26T family, 80-pin LFQFP, 256 KB flash, 48 KB SRAM, identical peripherals except reduced ADC channel count (7+8 vs. 4+4+14) | Limited to single-shunt current sensing or lower-resolution position feedback due to fewer simultaneous-sampling ADC units | Select when cost-sensitive designs require reduced pin count and lower memory footprint without sacrificing CAN FD or HRPWM capability |
| R5F566TEBDFP#30 | RX66T family, 100-pin LFQFP, 160 MHz, 1 MB flash, 256 KB SRAM, adds EtherCAT slave support and enhanced TFUv3 | Targets higher-tier servo drives requiring real-time Ethernet synchronization and faster FOC loop execution (<250 ns) | Choose for next-generation industrial automation where deterministic network timing and larger code space justify premium pricing |
Compared with R5F526T9BGFM#10, the R5F526TADFM#30 offers identical safety and PWM features in a smaller package but sacrifices simultaneous 3-unit ADC sampling; the R5F566TEBDFP#30 delivers higher performance and EtherCAT readiness at increased cost and power - making R5F526T9BGFM#10 the optimal balance for cost-constrained, safety-critical inverter designs.

The R5F526T9BGFM#10 operates at a maximum frequency of 120 MHz using the 32-bit RXv3 CPU core. It delivers 709 CoreMark performance and supports single-cycle instruction execution, IEEE 754-compliant single-precision floating-point unit, and collective register bank save for rapid context switching - all essential for real-time motor control loops. The R5F526T9BGFM#10's architecture enables deterministic timing critical for field-oriented control algorithms.
Does the R5F526T9BGFM#10 support IEC60730 Class B compliance out of the box?
Yes, the R5F526T9BGFM#10 includes dedicated hardware features required for IEC60730 Class B certification: oscillation-stop detection, RAM test assist via DOC, CRC calculator (CRCA), memory protection unit (MPU), register write protection, and independent watchdog timer (IWDT) with window function. These capabilities are documented in Renesas Application Note R01AN4229JJ0100 and eliminate the need for external safety monitors when properly implemented. The R5F526T9BGFM#10 is widely deployed in certified compressor and pump controllers.
What ADC configuration does the R5F526T9BGFM#10 provide, and how many channels support simultaneous sampling?
The R5F526T9BGFM#10 integrates three independent 12-bit S12ADH units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels), totaling 22 analog inputs. Units 0 and 1 each include three dedicated sample-and-hold circuits, enabling true simultaneous sampling across up to six channels - critical for accurate three-phase current reconstruction. Unit 2 provides additional channels for voltage sensing and temperature monitoring. This configuration is confirmed in R01DS0407EJ0120 Section 1.1 Table 1.1.
What is the resolution and timing capability of the HRPWM in the R5F526T9BGFM#10?
The R5F526T9BGFM#10 features four-channel High-Resolution PWM (HRPWM) that controls the rising/falling edges of GPTWa-generated waveforms with a minimum resolution of 260 ps when operating at 120 MHz. This capability is achieved via dedicated timing adjustment logic synchronized to the PCLKC clock domain and enables precise dead-time tuning for SiC/GaN power stages. The specification is explicitly stated in the "High-resolution PWM waveform generation circuit (HRPWM)" section of the R01DS0407EJ0120 datasheet.
Which package type and pin count does the R5F526T9BGFM#10 use, and what is its thermal pad configuration?

This package supports efficient heat dissipation in motor drive applications and is RoHS compliant. Pin compatibility and mechanical dimensions are fully specified in Renesas Package Code PLQP0100KB-B documentation, and the thermal pad must be soldered to a PCB copper pour for optimal thermal performance.
