Overview
R5F526T9BGFL#30 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring a 120 MHz CPU core delivering 709 CoreMark, 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 HRPWM timing resolution.
For engineers reviewing the R5F526T9BGFL#30 datasheet, R5F526T9BGFL#30 pinout, R5F526T9BGFL#30 application, or R5F526T9BGFL#30 equivalent, key selection criteria include its 100-pin LFQFP package, dual-bank flash for safe firmware updates, IEC60730-compliant safety features (IWDT, oscillation-stop detection, CRC, RAM test assist), and dedicated motor control peripherals including MTU3d, GPTWa, and HRPWM.
Technical Context
The R5F526T9BGFL#30 implements the RXv3 CPU core with single-cycle instruction execution, 16 general-purpose 32-bit registers, and IEEE 754-compliant single-precision FPU - enabling real-time field-oriented control (FOC) algorithms. Its clock system integrates PLL with external 8–24 MHz crystal support, internal HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator.
Motor control capability is anchored by three timer subsystems: MTU3d (16-bit × 9 channels) for 3-phase complementary PWM with automatic dead-time insertion; GPTWa (32-bit × 8 channels) supporting single-/3-/5-phase complementary modes; and HRPWM (4 channels) providing 260 ps minimum timing resolution for precise gate drive edge placement at 120 MHz operation.

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#30 | Same RX26T family, 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 designs where firmware size <256 KB and RAM usage <48 KB - e.g., single-motor fan controllers without advanced diagnostics. | Select when full 512 KB flash and 64 KB SRAM are unnecessary; retains same pinout, software compatibility, and motor control feature set. |
| R5F566TEBGFP#30 | RX66T family part in 100-pin LQFP; higher 160 MHz CPU, 1 MB flash, enhanced GPTW (32-bit × 16 ch), but no HRPWM or TFUv2. | Better suited for multi-axis servo drives requiring higher compute throughput and larger code footprint, but lacks sub-nanosecond PWM timing for ultra-low-noise inverters. | Choose for applications needing >120 MHz performance and larger memory, accepting trade-off of no 260 ps HRPWM - requires PCB redesign due to different pin assignment. |
Compared with R5F526T9BGFL#30, R5F526TADGFL#30 offers identical motor control peripherals and pin compatibility at lower memory capacity, while R5F566TEBGFP#30 delivers higher CPU performance and memory but sacrifices HRPWM precision and TFU acceleration - making R5F526T9BGFL#30 optimal for noise-sensitive, safety-critical inverter designs requiring deterministic sub-ns timing.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526T9BGFL#30?
The R5F526T9BGFL#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark - measured under standard conditions per EEMBC methodology. This performance level enables real-time execution of complex motor control algorithms such as field-oriented control (FOC) and model-predictive control (MPC) without external coprocessors. The RXv3 core's single-cycle instruction execution and integrated FPU further enhance deterministic timing for safety-critical loops in the R5F526T9BGFL#30.
Does the R5F526T9BGFL#30 support IEC60730 Class B compliance for household appliances?
Yes, the R5F526T9BGFL#30 includes dedicated hardware features required for IEC60730 Class B compliance: independent watchdog timer (IWDT) with window function, oscillation-stop detection, CRC calculator (CRCA), RAM test-assist function via DOC, register write protection, and self-diagnostic A/D converter functions. These are documented in Renesas Application Note R01AN3819JJ0100 and validated in the R5F526T9BGFL#30's safety manual - enabling certified implementations without external safety monitors.
What PWM configurations does the R5F526T9BGFL#30 support for 3-phase inverter control?
The R5F526T9BGFL#30 supports three complementary PWM modes essential for 3-phase inverter control: 10-channel single-phase, 3-channel 3-phase, and 2-channel 5-phase complementary outputs - implemented across MTU3d and GPTWa peripherals. It also provides automatic dead-time insertion, synchronous start/stop across channels, and hardware fault response via POE3D/POEG. The 260 ps HRPWM resolution allows precise edge placement to minimize shoot-through risk and EMI in high-efficiency SiC/GaN-based inverters using the R5F526T9BGFL#30.
How many analog-to-digital converter channels does the R5F526T9BGFL#30 have, and what is their sampling capability?
The R5F526T9BGFL#30 integrates a 12-bit S12ADH ADC with 22 total input channels distributed across three sample-and-hold units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels). Minimum conversion time is 0.9 µs per channel at 60 MHz ADCLK, and simultaneous sampling across all three units is supported - critical for capturing phase currents and DC-link voltage in a single control cycle. This architecture is explicitly confirmed for the 100-pin variant (R5F526T9BGFL#30) in Table 1.2 of R01DS0407EJ0120 Rev.1.20.
Is the R5F526T9BGFL#30 pin-compatible with other RX26T group MCUs in the same package?
Yes, the R5F526T9BGFL#30 is pin-compatible with other RX26T devices in the 100-pin LFQFP (PLQP0100KB-B) package, including R5F526TADGFL#30 and R5F526TBDGFL#30 - sharing identical pin assignments for power, ground, reset, clocks, JTAG/FINE debug, and all peripheral I/O. This allows hardware reuse across memory variants while maintaining software compatibility through Renesas' unified RX Family SDK and e2 studio toolchain for the R5F526T9BGFL#30.
