Product details
Overview
R5F526TACGFM#30 from Renesas is a 32-bit RXv3 core microcontroller optimized for motor control, featuring 120 MHz operation, 512 KB on-chip code flash, 64 KB SRAM, and integrated CAN FD, high-resolution PWM (260 ps min. resolution), and dual-bank flash for safe firmware updates - deployed in industrial inverters and servo drives.
For engineers reviewing the R5F526TACGFM#30 datasheet, R5F526TACGFM#30 pinout, R5F526TACGFM#30 application, or R5F526TACGFM#30 equivalent, key selection criteria include 3-phase/5-phase complementary PWM capability, IEC60730 safety support (oscillation detection, RAM test assist, CRC), Trusted Secure IP Lite encryption, and 120 MHz real-time timer synchronization with PCLKA/PCLKC domains.
Technical Context
The R5F526TACGFM#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16 register banks for fast context switching - enabling deterministic motor control loops. Its clock system supports independent PCLKA (up to 120 MHz), PCLKC (up to 120 MHz for GPTW/HRPWM timing), and PCLKD (up to 60 MHz for A/D conversion) domains.
Hardware acceleration includes DMACAa (8-channel DMA), ELC (183-event interlinking), and dedicated peripherals: MTU3d (9-channel 16-bit timer), GPTWa (8-channel 32-bit timer), HRPWM (4-channel sub-ns PWM fine-tuning), and S12ADH (three 12-bit A/D units with simultaneous sampling across 23 channels).

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F526TADGFM#30 | Same RX26T family, identical pinout and peripheral set, but with 256 KB code flash and 48 KB SRAM | Targeted at cost-sensitive, lower-complexity motor control where dual-bank flash and full 64 KB SRAM are not required | Select when firmware size ≤256 KB and simultaneous 23-channel ADC sampling is unnecessary |
| R5F566TEAGFP#30 | RX66T family; higher 160 MHz CPU, 1 MB flash, enhanced GPTW (12 ch), larger S12ADH (32 ch), no HRPWM | Designed for advanced multi-axis servo systems requiring higher computational throughput and larger memory footprint | Choose for applications needing >120 MHz real-time performance, larger code space, or more analog channels - not drop-in compatible |
Compared with R5F526TACGFM#30, the R5F526TADGFM#30 offers identical timing/peripheral compatibility at reduced memory capacity, while the R5F566TEAGFP#30 delivers higher performance and scalability but requires PCB redesign due to different package (144-pin LQFP) and non-overlapping peripheral register maps.
