Product details
Overview
R5F526TFDGFM#50 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 hardware-accelerated 3-phase/5-phase complementary PWM generation with 260 ps timing resolution.
For engineers reviewing the R5F526TFDGFM#50 datasheet, R5F526TFDGFM#50 pinout, R5F526TFDGFM#50 application, or R5F526TFDGFM#50 equivalent, key selection criteria include real-time PWM precision (HRPWM), IEC60730 safety support (IWDT, oscillation detection, CRC, self-diagnostic A/D), dual-bank flash for safe firmware updates, and simultaneous sampling across three 12-bit A/D units - all in a 100-pin LFQFP package rated for –40°C to +85°C operation.
Technical Context
The R5F526TFDGFM#50 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 (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator, enabling independent peripheral clock domains (PCLKA up to 120 MHz, PCLKB/C/D at configurable ratios).
Motor control is enabled by tightly coupled peripherals: GPTWa (8-channel 32-bit timer) and MTU3d (9-channel 16-bit timer) provide synchronized PWM outputs with dead-time insertion and phase-counting; HRPWM refines GPTW0–GPTW3 edges to 260 ps resolution; ELC links events (e.g., timer overflow → A/D trigger) without CPU intervention; and S12ADH supports simultaneous sampling across three 12-bit A/D units (4+4+14 channels) with programmable gain amplifiers.

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#50 | Same RX26T group, identical 100-pin LFQFP package and core specs, but with 256 KB code flash and 48 KB SRAM instead of 512 KB/64 KB | Targeted at cost-sensitive designs where full memory capacity is unnecessary; reduced A/D unit count (2 units vs. 3) limits simultaneous channel count | Select when firmware size < 256 KB and 3-unit simultaneous A/D sampling is not required - reduces BOM cost without sacrificing PWM or safety features |
| R5F566TEBGFM#50 | RX66T group part: higher 160 MHz CPU, larger 1 MB flash/256 KB SRAM, enhanced GPTW (12-channel), additional CAN FD channel, but no HRPWM or Trusted Secure IP Lite | Designed for more complex servo drives and multi-axis motion controllers requiring higher compute throughput and expanded connectivity | Choose for next-generation designs needing >120 MHz performance, extra CAN FD bandwidth, or larger code footprint - trade-off is loss of 260 ps HRPWM and AES encryption engine |
Compared with R5F526TFDGFM#50, the R5F526TADGFM#50 offers identical motor control peripherals and safety features at lower memory density, while the R5F566TEBGFM#50 delivers higher CPU performance and expanded I/O but omits HRPWM and cryptographic acceleration - making R5F526TFDGFM#50 optimal for cost-constrained, safety-critical inverter applications demanding nanosecond-level PWM fidelity.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526TFDGFM#50?
The R5F526TFDGFM#50 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, barrel shifter, and on-chip FPU - all validated per the official Renesas R01DS0407EJ0120 datasheet Rev.1.20. The R5F526TFDGFM#50 sustains this speed across its 512 KB flash and 64 KB SRAM with zero wait states.
Does the R5F526TFDGFM#50 support CAN FD, and what standard does it comply with?
Yes, the R5F526TFDGFM#50 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames at data rates up to 5 Mbps in FD mode. It includes dedicated TX/RX pins, message RAM with flexible filtering, and error counters - all accessible via the CANFD peripheral block. This capability is confirmed in the R01DS0407EJ0120 datasheet Section 1.1 and makes the R5F526TFDGFM#50 suitable for modern automotive and industrial networks requiring higher bandwidth than classical CAN.
How many A/D converter channels does the R5F526TFDGFM#50 support, and what is its sampling architecture?
The R5F526TFDGFM#50 supports 22 total 12-bit A/D channels distributed across three independent S12ADH units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels). Its architecture enables true simultaneous sampling across all three units using shared or independent triggers - critical for multi-phase current sensing. Minimum conversion time is 0.9 µs per channel at 60 MHz ADCLK, and each unit includes dedicated sample-and-hold circuits (3 per unit for Units 0/1). This configuration is explicitly defined for the 64 KB RAM variant in the R5F526TFDGFM#50 datasheet.
What safety features does the R5F526TFDGFM#50 include for IEC60730 compliance?
The R5F526TFDGFM#50 includes multiple hardware-based IEC60730 compliance features: independent watchdog timer (IWDT) with windowing function, main clock oscillation stoppage detection, CRC calculator (CRCA) supporting 8-/32-bit polynomials, memory protection unit (MPU) with eight configurable regions, register write protection, and analog comparator disconnection detection. These are documented in the "Useful functions for IEC60730 compliance" section of the R01DS0407EJ0120 datasheet and enable self-test routines without external components - essential for Class B certification in the R5F526TFDGFM#50.
What is the package type and thermal specification of the R5F526TFDGFM#50?
The R5F526TFDGFM#50 uses the PLQP0100KB-B package: a 100-pin Low-profile Quad Flat Package measuring 14 mm × 14 mm with 0.5 mm lead pitch and an exposed thermal pad. It is rated for operation from –40°C to +85°C (D-version), with thermal resistance θJA of 30°C/W typical. This package is specified in Table 1.2 of the R01DS0407EJ0120 datasheet and supports reflow soldering per J-STD-020. The R5F526TFDGFM#50's thermal design accommodates continuous 120 MHz operation in industrial enclosures with passive cooling.
