Product details
Overview
R5F526TACGFL#10 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control, featuring a 120 MHz CPU core, 512 KB on-chip code flash, 64 KB SRAM, 16 KB data flash, and integrated high-resolution PWM (260 ps min. resolution) for precise inverter gate timing. It integrates CAN FD, dual 12-bit ADC units with simultaneous sampling, 6-channel analog comparators, and hardware encryption (AES-128/256) - deployed in industrial servo drives and HVAC compressor controllers.
For engineers reviewing the R5F526TACGFL#10 datasheet, R5F526TACGFL#10 pinout, R5F526TACGFL#10 application, or R5F526TACGFL#10 equivalent, key selection criteria include its 100-pin LFQFP package, 3-phase/5-phase complementary PWM capability, IEC60730 safety support (oscillation detection, RAM test assist, CRC), and Trusted Secure IP Lite for firmware integrity - all validated for real-time motor control at –40°C to +105°C.
Technical Context
The R5F526TACGFL#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16-register bank save for fast context switching in interrupt-heavy motor control loops. Its clock system combines an 8–24 MHz external crystal with PLL multiplication to achieve 120 MHz ICLK, while PCLKA/PCLKC run at up to 120 MHz to synchronize GPTWa, MTU3d, and HRPWM peripherals.
Motor-specific timing is enforced via ELC-linked event triggering: MTU3d and GPTWa generate A/D conversion triggers synchronized to PWM edges, while HRPWM fine-tunes rising/falling edge timing of GPTW0–GPTW3 outputs with 260 ps resolution - enabling dead-time compensation and distortion-free 3-phase inverter waveforms without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F526TADGFL#10 | Same RX26T Group, identical 100-pin LFQFP package and peripheral set, but with 256 KB code flash and 48 KB SRAM instead of 512 KB/64 KB. | Targeted at cost-sensitive motor control applications with smaller firmware footprints and lower RAM requirements (e.g., basic V/f fans). | Select when full 512 KB flash and 64 KB SRAM are unnecessary - reduces memory cost while retaining identical pinout, PWM, and safety features. |

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526TACGFL#10?
The R5F526TACGFL#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark when running at that speed. This performance level is enabled by the RXv3 CPU core's single-cycle instruction execution, 32-bit multiplier/divider, and barrel shifter - making it suitable for demanding real-time motor control algorithms such as field-oriented control (FOC) with sub-microsecond loop times.
Does the R5F526TACGFL#10 support IEC60730 Class B compliance out of the box?
Yes, the R5F526TACGFL#10 includes hardware features required for IEC60730 Class B compliance: oscillation-stop detection, independent watchdog timer (IWDT) with window function, clock frequency accuracy measurement circuit, RAM test assist via DOC, CRC calculator (CRCA), and register write protection. These are documented in the R01DS0407EJ0120 datasheet and do not require external components to implement basic Class B self-test routines.
What PWM configurations does the R5F526TACGFL#10 support for 3-phase inverter control?
The R5F526TACGFL#10 supports 3-phase complementary PWM using both MTU3d (2 output channels) and GPTWa (10 output channels in single-phase or 3 output channels in 3-phase mode). Its HRPWM module further refines timing on GPTW0–GPTW3 outputs with 260 ps resolution - enabling precise dead-time insertion and elimination of shoot-through in SiC/GaN-based inverters without software intervention.
How many analog-to-digital converter (ADC) channels does the R5F526TACGFL#10 have, and what is their sampling capability?
The R5F526TACGFL#10 includes two 12-bit S12ADH ADC units totaling 22 channels: Unit 0 (7 channels) and Unit 2 (15 channels). It supports simultaneous sampling across three sample-and-hold circuits, with a minimum conversion time of 0.9 µs per channel at 60 MHz ADCLK - enabling synchronized acquisition of three-phase motor currents for accurate field-oriented control.
Is the R5F526TACGFL#10 pin-compatible with other RX26T Group MCUs like the R5F526TADGFL#10?
Yes, the R5F526TACGFL#10 and R5F526TADGFL#10 share identical PLQP0100KB-B 100-pin LFQFP packaging and pinout. Both devices offer the same peripheral set, I/O configuration, and electrical characteristics - differing only in memory capacity (512 KB vs. 256 KB flash, 64 KB vs. 48 KB SRAM). This allows direct substitution in existing designs where firmware size permits.
