Product details
Overview
R5F526TFCDNE#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 R5F526TFCDNE#10 datasheet, R5F526TFCDNE#10 pinout, R5F526TFCDNE#10 application, or R5F526TFCDNE#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 motor control peripherals including MTU3d, GPTWa, and HRPWM supporting real-time dead-time compensation and synchronous A/D triggering.
Technical Context
The R5F526TFCDNE#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-critical for deterministic motor control loops. Its clock system supports independent PCLKA (120 MHz), PCLKC (120 MHz for timer reference), and PCLKD (60 MHz for A/D) domains to decouple high-speed PWM timing from analog conversion timing.
Motor-specific peripherals are tightly coordinated: MTU3d provides 3-phase complementary PWM with automatic dead-time insertion and phase-counting mode; GPTWa delivers up to 10 single-phase complementary PWM outputs at 120 MHz; and HRPWM overlays 260 ps fine timing control on GPTW0–GPTW3 outputs. All three modules synchronize A/D conversion triggers via ELC without CPU intervention.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526TFCDNE#10?
The R5F526TFCDNE#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This benchmark reflects its RXv3 CPU core's efficient pipeline, single-cycle instruction execution, and integrated FPU - enabling deterministic execution of complex motor control algorithms within tight timing budgets. The R5F526TFCDNE#10 sustains this performance with zero-wait-state access to both 512 KB flash and 64 KB SRAM.
Does the R5F526TFCDNE#10 support IEC60730 Class B compliance out of the box?
Yes, the R5F526TFCDNE#10 integrates hardware features required for IEC60730 Class B compliance, including oscillation-stop detection, RAM test assist via DOC, CRCA for data integrity, independent watchdog timer with window function, and register write protection. These capabilities reduce software safety layer complexity and accelerate certification - the R5F526TFCDNE#10 is explicitly validated for use in safety-critical motor control applications per the official Renesas IEC60730 documentation.
How does the Event Link Controller (ELC) improve real-time performance in the R5F526TFCDNE#10?
The ELC in the R5F526TFCDNE#10 eliminates CPU intervention for time-critical peripheral coordination by directly linking 183 internal events (e.g., MTU3d overflow, comparator match) to target functions (e.g., A/D conversion start, GPTWa counter clear). For example, an MTU3d PWM edge event can trigger simultaneous A/D sampling across three S12ADH units - achieving sub-microsecond latency and freeing the CPU for control law computation. This hardware event routing is fully configurable and operates during sleep modes.
What PWM configurations does the R5F526TFCDNE#10 support for 3-phase inverter control?
The R5F526TFCDNE#10 supports three complementary PWM modes essential for 3-phase inverter control: 3-phase complementary PWM (via MTU3d, 2 output channels), 5-phase complementary PWM (via GPTWa, 2 output channels), and single-phase complementary PWM (via GPTWa, 10 output channels). All modes include hardware dead-time insertion, fault-driven output disable (via POEG), and synchronous A/D triggering - enabling robust, high-efficiency motor drive implementations without external logic.
Is the R5F526TFCDNE#10 pin-compatible with other RX26T group MCUs?
No, the R5F526TFCDNE#10 uses the 100-pin PLQP0100KB-B package, which is not pin-compatible with smaller RX26T variants (e.g., 64-pin or 48-pin packages). While peripheral functionality is consistent across the RX26T family, pin assignments for GPTWa, MTU3d, and A/D channels differ between package options. Migration requires PCB redesign; however, firmware reuse is supported through Renesas' common RX driver APIs and e2 studio development environment.
