Product details
Overview
R5F526T9BGFN#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 timing resolution.
For engineers reviewing the R5F526T9BGFN#10 datasheet, R5F526T9BGFN#10 pinout, R5F526T9BGFN#10 application, or R5F526T9BGFN#10 equivalent, key selection criteria include its dual-bank flash architecture for safe firmware updates, IEC60730-compliant safety features (oscillation-stop detection, RAM test assist, CRC calculator), and dedicated HRPWM circuitry enabling precise gate-drive timing in BLDC/PMSM motor drives.
Technical Context
The R5F526T9BGFN#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-critical for real-time motor control loops. Its clock system integrates PLL, 240-kHz LOCO, and 120-kHz IWDT-dedicated oscillator, with independent PCLKA (120 MHz), PCLKC (120 MHz), and PCLKD (60 MHz) domains to synchronize high-speed timers, HRPWM, and A/D conversion independently.
Peripheral integration centers on deterministic timing control: GPTWa (8-channel 32-bit timer) and MTU3d (9-channel 16-bit timer) support simultaneous 3-phase PWM with automatic dead-time insertion, while ELC enables interrupt-free inter-module triggering (e.g., MTU-triggered A/D sampling). The S12ADH ADC includes three sample-and-hold units for synchronized multi-channel acquisition-essential for current/voltage sensing in vector-controlled inverters.

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, 256 KB flash, 48 KB SRAM, 48-pin HWQFN package-reduced memory and I/O count. | Suitable for cost-sensitive single-phase or low-power BLDC applications where 3-phase PWM and full ADC channel count are not required. | Select when BOM cost reduction outweighs need for dual-bank flash, HRPWM, and full 100-pin I/O expansion. |
| R5F566TEBGFN#10 | RX66T family successor: 160 MHz CPU, 1 MB flash, enhanced GPTP timer, higher CAN FD bandwidth, but no HRPWM circuit. | Targets next-gen high-efficiency inverters needing faster computation and larger code space, but lacks sub-ns PWM timing resolution. | Choose for future-proof designs requiring higher performance and memory headroom, accepting trade-off in ultra-fine PWM timing precision. |
Compared with R5F526T9BGFN#10, R5F526TADGFN#10 reduces flash/SRAM and eliminates HRPWM-making it viable only for simpler motor topologies-while R5F566TEBGFN#10 trades HRPWM's 260 ps resolution for broader peripheral bandwidth and larger memory, better suited for AI-enhanced predictive maintenance rather than nanosecond-critical gate control.
