Product details
Overview
R5F526TBCGNE#10 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, operating at up to 120 MHz with 709 CoreMark performance, 512 KB on-chip code flash, 64 KB SRAM, and integrated CAN FD, high-resolution PWM (260 ps min. resolution), and dual-bank flash for safe firmware updates.
For engineers reviewing the R5F526TBCGNE#10 datasheet, R5F526TBCGNE#10 pinout, R5F526TBCGNE#10 application, or R5F526TBCGNE#10 equivalent, key selection criteria include its 100-pin LFQFP package, 3-phase/5-phase complementary PWM capability, IEC60730 safety features, and support for real-time motor control loops requiring sub-microsecond timing precision and deterministic interrupt latency.
Technical Context
The R5F526TBCGNE#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 in motor control ISR handling. Its clock system supports PLL-synthesized 120 MHz ICLK with independent PCLKA/PCLKC domains enabling simultaneous 120 MHz peripheral operation (MTU3d, GPTWa, HRPWM) and 60 MHz A/D conversion timing.
Hardware acceleration includes dedicated MTU3d (9-channel 16-bit timer) and GPTWa (8-channel 32-bit timer) with synchronized PWM output, dead-time insertion, and ELC-triggered A/D start-enabling tightly coupled current/voltage sampling and gate drive modulation without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F526TADGNE#10 | Same RX26T family, 64-pin HWQFN package (PWQN0064KF-A), reduced I/O count (49 pins), 48 KB SRAM, 256 KB flash. | Suitable for space-constrained inverters with fewer analog inputs and simplified PWM requirements (no 5-phase mode). | Select when board area is critical and full 100-pin I/O and 64 KB SRAM are unnecessary. |
| R5F523T7ADNG#U0 | RX23T family, 64-pin LQFP, 40 MHz max CPU speed, no HRPWM, 128 KB flash, 16 KB SRAM, single 12-bit ADC unit. | Targeted at cost-sensitive fan/pump controllers where sub-µs PWM resolution and dual ADC units are not required. | Choose for entry-level BLDC control where 120 MHz timing and IEC60730 certification are not mandated. |
Compared with R5F526TBCGNE#10, the R5F526TADGNE#10 offers identical peripheral functionality in a smaller footprint but sacrifices I/O count and SRAM capacity, while the R5F523T7ADNG#U0 reduces cost and complexity at the expense of PWM resolution, processing throughput, and safety feature depth - making it suitable only for non-safety-critical, lower-performance motor control.
