Product details
Overview
R5F526TBAGFN#30 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 high-resolution PWM with 260 ps timing resolution. It supports IEC60730 safety compliance and operates across –40°C to +105°C.
For engineers reviewing the R5F526TBAGFN#30 datasheet, R5F526TBAGFN#30 pinout, R5F526TBAGFN#30 application, or R5F526TBAGFN#30 equivalent, key selection considerations include its 100-pin HWQFN package (PWQN0064KF-A), dual-bank flash for safe firmware updates, simultaneous sampling across three 12-bit A/D units, and hardware-accelerated trigonometric functions (TFUv2) for real-time motor vector control.
Technical Context
The R5F526TBAGFN#30 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 in interrupt-heavy motor control loops. Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator - enabling independent timing domains for PCLKA (120 MHz), PCLKB (60 MHz), PCLKC (120 MHz), and PCLKD (60 MHz).
Peripheral coordination is managed via the Event Link Controller (ELC), which interconnects 183 internal event signals - allowing MTU3d, GPTWa, and S12ADH to trigger each other without CPU intervention. The device uses Trusted Memory (TM) to protect boot code in flash and includes MPU with eight configurable protection areas for memory safety-critical tasks.

Key Features
| Feature | Design Value |
|---|---|
| Trusted Memory (TM) | Protects boot code in flash from unauthorized read access - only CPU instruction fetch allowed, preventing firmware extraction during field servicing. |
| Event Link Controller (ELC) | Eliminates CPU polling overhead by directly linking 183 internal events - e.g., MTU overflow → GPTW start → A/D conversion trigger → CRCA checksum generation. |
| High-Resolution PWM (HRPWM) | 260 ps minimum timing resolution on GPTW0–GPTW3 outputs - enables sub-microsecond dead-time control critical for SiC/GaN inverter gate drivers. |
| Simultaneous Sampling A/D | Three independent S12ADH units (4+4+14 channels) sample concurrently - captures instantaneous motor phase currents and DC-link voltage without time skew. |
| Trigonometric Function Unit (TFUv2) | Hardware-accelerated sine/cosine/arctan/hypotenuse - reduces FOC computation latency from >10 µs (software) to <1 µs, freeing CPU cycles for communication or diagnostics. |
