Product details
Overview
R5F526TFCGND#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 complementary PWM generation with dead-time control.
For engineers reviewing the R5F526TFCGND#10 datasheet, R5F526TFCGND#10 pinout, R5F526TFCGND#10 application, or R5F526TFCGND#10 equivalent, key selection criteria include its 120 MHz GPTWa timer with 10-channel single-phase complementary PWM, 260 ps HRPWM timing resolution, IEC60730-compliant safety features (IWDT, oscillation-stop detection, RAM test assist), and support for simultaneous sampling across three 12-bit A/D units.
Technical Context
The R5F526TFCGND#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 integrates an 8–24 MHz external crystal oscillator, PLL for 120 MHz system clock, and dedicated 120 kHz IWDT oscillator - all supporting IEC60730 Class B compliance.
Motor control is enabled by tightly coupled peripherals: MTU3d (9-channel 16-bit timer) and GPTWa (8-channel 32-bit timer) operate synchronously with PCLKC up to 120 MHz, while HRPWM provides sub-nanosecond edge placement for precise gate drive timing. The ELC allows event-triggered peripheral coordination without CPU intervention - critical for real-time inverter control loops.

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F526TDDGND#10 | Same RX26T family, identical 100-pin PLQP0100KB-B package, but with 256 KB code flash and 48 KB SRAM instead of 512 KB/64 KB. | Targeted at cost-sensitive motor drives where firmware size and RAM usage are constrained - lacks dual-bank flash for seamless firmware updates. | Select when application firmware fits within 256 KB and does not require simultaneous 3-unit ADC sampling or full HRPWM feature set. |
| R5F523T5DDFK#30 | RX23T family part in 64-pin LQFP; 40 MHz CPU, 256 KB flash, 32 KB RAM, single 12-bit ADC unit, no HRPWM or CAN FD. | Entry-level motor control for single-phase or low-power BLDC applications - lacks IEC60730 safety features and advanced PWM timing. | Choose only for non-safety-critical, lower-performance applications where CAN FD, 120 MHz timing, and triple ADC are unnecessary. |
Compared with R5F526TFCGND#10, the R5F526TDDGND#10 offers identical package and peripheral compatibility but reduced memory - ideal for scaled-down firmware; the R5F523T5DDFK#30 is a legacy-generation part with significantly lower performance, no CAN FD, and no HRPWM - unsuitable as a drop-in replacement for demanding inverter designs.
