Product details
Overview
R5F526TBDGFN#10 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 HRPWM timing resolution.
For engineers reviewing the R5F526TBDGFN#10 datasheet, R5F526TBDGFN#10 pinout, R5F526TBDGFN#10 application, or R5F526TBDGFN#10 equivalent, key selection considerations include its 100-pin LFQFP package, dual-bank flash architecture enabling background programming, IEC60730-compliant safety features (IWDT, oscillation-stop detection, RAM test assist), and dedicated motor control peripherals including MTU3d, GPTWa, and HRPWM.
Technical Context
The R5F526TBDGFN#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16-register bank save for fast context switching. Its clock system integrates an 8–24 MHz external crystal oscillator, 240 kHz LOCO, and 16/18/20 MHz HOCO, with PLL multiplication enabling 120 MHz operation across ICLK, PCLKA (up to 120 MHz), and PCLKC (up to 120 MHz) domains.
Motor control execution relies on tightly coupled timer subsystems: MTU3d provides 9-channel 16-bit PWM with automatic dead-time insertion and 3-phase complementary output; GPTWa delivers 8-channel 32-bit PWM with synchronous start/stop and ELC-triggered A/D conversion; HRPWM adds 4-channel sub-nanosecond edge placement (260 ps min) synchronized to GPTW outputs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F526TADGFN#10 | Same RX26T family, identical 100-pin LFQFP package, but with 256 KB code flash and 48 KB SRAM instead of 512 KB/64 KB | Targeted at cost-sensitive motor control where reduced memory footprint suffices for basic FOC or scalar control | Select when firmware size <256 KB and RAM usage <48 KB; retains all peripheral sets (CAN FD, HRPWM, MTU3d) and safety features |
