Product details
Overview
R5F526TFBGFN#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 integrates dual-bank flash for safe firmware updates, hardware encryption (AES-128/256), and IEC60730-compliant safety functions.
For engineers reviewing the R5F526TFBGFN#10 datasheet, R5F526TFBGFN#10 pinout, R5F526TFBGFN#10 application, or R5F526TFBGFN#10 equivalent, key selection criteria include 3-phase/5-phase complementary PWM capability, simultaneous sampling across three 12-bit ADC units, 5-V tolerant I/O support, and Trusted Secure IP Lite for secure boot and key management.
Technical Context
The R5F526TFBGFN#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 supports PLL multiplication of external 8–24 MHz crystals or internal HOCO (16/18/20 MHz) to achieve 120 MHz ICLK, with independent PCLKA/PCLKC domains enabling concurrent 120 MHz peripheral operation for GPTWa, MTU3d, and HRPWM.
Motor control is enabled by tightly coupled peripherals: GPTWa (32-bit × 8 channels) and MTU3d (16-bit × 9 channels) provide complementary PWM with programmable dead-time insertion and synchronous start/stop; HRPWM refines GPTW0–GPTW3 outputs to 260 ps resolution; S12ADH delivers simultaneous sampling across three 12-bit ADC units (4+4+14 channels) with sample-and-hold per channel and digital comparison.

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F526TDDDFP#30 | Same RX26T family, 64-pin HWQFN (PWQN0064KF-A), 256 KB flash, 48 KB SRAM, 48 I/O pins | Limited to 2×12-bit ADC units (7+8 ch), no simultaneous sampling across three units; reduced PWM channel count (16-bit GPTWa × 8) | Select when space-constrained designs prioritize footprint (9×9 mm) over full ADC/PWM feature set and require only basic 3-phase control. |
| R5F566TEBDFP#30 | RX66T family, 100-pin LFQFP, 120 MHz, 512 KB flash, 128 KB SRAM, enhanced TFUv2 trigonometric accelerator | Higher SRAM enables larger FOC lookup tables; TFUv2 reduces sine/cosine computation latency by 65% vs. RX26T's TFUv2 | Choose for high-dynamic-response servo drives where computational throughput for real-time vector math exceeds RX26T capabilities. |
Compared with R5F526TFBGFN#10, R5F526TDDDFP#30 offers smaller form factor but sacrifices simultaneous 3-unit ADC sampling and full HRPWM capability, while R5F566TEBDFP#30 delivers higher compute headroom and faster trigonometric processing at the cost of increased power and bill-of-material complexity.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526TFBGFN#10?
The R5F526TFBGFN#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark points under benchmark conditions. This performance stems from its RXv3 CPU core with single-cycle instruction execution, 32-bit multiplier/divider, and barrel shifter-enabling efficient real-time motor control algorithms without external co-processors. The R5F526TFBGFN#10 sustains this speed across all memory and peripheral accesses due to 120 MHz no-wait flash and SRAM.
Does the R5F526TFBGFN#10 support simultaneous sampling across all ADC channels?
Yes, the R5F526TFBGFN#10 supports true simultaneous sampling across three independent 12-bit S12ADH units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels). Each unit includes dedicated sample-and-hold circuits, allowing synchronized acquisition of phase currents, DC-link voltage, and temperature signals in a single control cycle-critical for accurate field-oriented control. This capability is confirmed in the R01DS0407EJ0120 datasheet Section 1.1, Table 1.1.
What PWM configurations does the R5F526TFBGFN#10 support for 3-phase motor control?
The R5F526TFBGFN#10 supports 3-phase complementary PWM via both MTU3d (9 channels, 2-output 3-phase mode) and GPTWa (32-bit × 8 channels, 3-output 3-phase mode), with automatic dead-time insertion and non-overlapping waveform generation. It also provides 5-phase complementary PWM (2 channels) and single-phase complementary PWM (10 channels). The integrated HRPWM refines GPTW0–GPTW3 outputs to 260 ps resolution, enabling precise timing control for reduced electromagnetic interference in inverter designs.
Is the R5F526TFBGFN#10 qualified for IEC60730 Class B compliance?
Yes, the R5F526TFBGFN#10 includes hardware features required for IEC60730 Class B compliance: oscillation-stoppage detection, A/D converter disconnection detection, clock frequency accuracy measurement, independent watchdog timer (IWDTa), RAM test-assisting function (DOC), CRC calculator (CRCA), and register write protection. These are documented in the "Useful functions for IEC60730 compliance" section of the R01DS0407EJ0120 datasheet and do not require external components to implement.
What package type and pin count does the R5F526TFBGFN#10 use?
The R5F526TFBGFN#10 uses the PLQP0100KB-B package: a 100-pin Low-Profile Quad Flat Package with 14 mm × 14 mm body size, 0.5 mm pin pitch, and exposed thermal pad. This package supports 82 general-purpose I/O pins (including 2×5-V tolerant), 15 high-current outputs, and full peripheral routing for motor control-including dedicated MTU/GPTW PWM pins, CAN FD differential pairs, and ADC analog inputs-as specified in Renesas' RX26T Group documentation.
