Product details
Overview
R5F526TFAGFP#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 high-resolution PWM with 260 ps timing resolution. It supports IEC60730 safety compliance and includes Trusted Secure IP Lite encryption.
For engineers reviewing the R5F526TFAGFP#30 datasheet, R5F526TFAGFP#30 pinout, R5F526TFAGFP#30 application, or R5F526TFAGFP#30 equivalent, this MCU delivers deterministic real-time control for 3-phase and 5-phase motor drives, embedded power conversion, and safety-critical industrial systems requiring simultaneous sampling, hardware-accelerated trigonometric functions, and secure firmware execution.
Technical Context
The R5F526TFAGFP#30 integrates an RXv3 CPU core with single-precision FPU, memory protection unit (MPU), and Trusted Memory (TM) for secure code execution. Its clock system combines an 8–24 MHz external crystal with PLL to generate 120 MHz ICLK, while PCLKA, PCLKC, and PCLKD operate at up to 120 MHz, 120 MHz, and 60 MHz respectively to drive GPTW, HRPWM, and S12ADH modules independently.
It implements dual-bank flash for background programming and startup bank swapping, 12-bit A/D converters with three sample-and-hold units (totaling 22 channels), six analog comparators, two 12-bit D/A outputs usable as comparator references, and hardware-accelerated trigonometric functions (TFUv2) for vector control algorithms without software overhead.

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F526TDDFK#30 | Same RX26T family, 64-pin HWQFN (PWQN0064KF-A), 256 KB flash, 48 KB SRAM - smaller footprint, reduced analog channel count (15-channel S12ADH), no TFUv2. | Targeted at space-constrained BLDC fan controllers where trigonometric acceleration is unnecessary and 3-phase PWM suffices. | Select when board area is critical and full 22-channel sampling or FOC with sine/cosine is not required. |
| R5F566TEADFP#30 | RX66T family, 100-pin LFQFP, 120 MHz, 512 KB flash, 128 KB SRAM, enhanced GPTW (12-channel), 32-channel S12ADH, no HRPWM - higher memory but coarser PWM resolution (1 ns). | Designed for multi-axis servo drives requiring larger buffer space for motion profiles and additional ADC channels for position feedback. | Choose when scaling beyond single-motor control to coordinated multi-axis systems with complex trajectory planning. |
Compared with R5F526TFAGFP#30, the R5F526TDDFK#30 trades package size and peripheral count for compactness, while the R5F566TEADFP#30 expands memory and channel count at the expense of HRPWM precision - making R5F526TFAGFP#30 optimal for cost-sensitive, high-efficiency single-motor inverters demanding nanosecond-level timing fidelity.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526TFAGFP#30?
The R5F526TFAGFP#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance stems from its RXv3 CPU core architecture with collective register bank save, memory protection unit, and single-cycle instruction execution at full speed - enabling deterministic real-time response for motor control loops without jitter. The R5F526TFAGFP#30 sustains this throughput across all on-chip peripherals due to its multi-bus architecture and 120 MHz PCLKA/PCLKC domains.
Does the R5F526TFAGFP#30 support IEC60730 Class B compliance out of the box?
Yes, the R5F526TFAGFP#30 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stoppage detection, A/D converter disconnection detection, clock frequency accuracy measurement circuit, independent watchdog timer (IWDTa), RAM test-assisting function via DOC, and CRC calculator (CRCA). These are documented in the R01DS0407EJ0120 datasheet and require no external components - the R5F526TFAGFP#30 implements self-test routines that meet Annex H requirements when configured per Renesas application notes.
What is the resolution and timing capability of the HRPWM in the R5F526TFAGFP#30?
The HRPWM in the R5F526TFAGFP#30 achieves a minimum timing resolution of 260 ps when operating at 120 MHz, applied to GPTW0 through GPTW3 outputs. This allows sub-nanosecond dead-time adjustment critical for SiC and GaN power devices. The R5F526TFAGFP#30 uses PCLKC-synchronized counter clocks and dedicated HRPWM logic to maintain this precision independent of CPU load - verified in the "High resolution PWM (HRPWM)" section of the R01DS0407EJ0120 datasheet.
How many analog-to-digital converter channels does the R5F526TFAGFP#30 support, and what is their configuration?
The R5F526TFAGFP#30 supports 22 total channels across three 12-bit S12ADH units: Unit 0 (4 channels, 3 sample-and-hold circuits), Unit 1 (4 channels, 3 sample-and-hold circuits), and Unit 2 (14 channels). This configuration enables true simultaneous sampling across multiple sensors - for example, capturing phase currents and DC-link voltage concurrently in a 3-phase inverter. The R5F526TFAGFP#30 datasheet confirms this layout on page 9 under "12-bit A/D converter (S12ADH) (Products with 64 Kbytes of RAM)".
Is the R5F526TFAGFP#30 pin-compatible with other RX26T group MCUs?
No, the R5F526TFAGFP#30 is not pin-compatible with other RX26T variants - it uses the 100-pin PLQP0100KB-B LFQFP package, whereas alternatives like R5F526TDDFK#30 use 64-pin PWQN0064KF-A. Pin counts, I/O allocations, and peripheral mappings differ across packages; the R5F526TFAGFP#30's 82 GPIOs, dual CAN FD pins, and dedicated HRPWM outputs are unique to its 100-pin footprint. Migration requires PCB redesign, though software compatibility is maintained within the RX26T family.
