Renesas R5F526TAAGFM#10

Overview

R5F526TAAGFM#10 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring a 120 MHz CPU core delivering 709 CoreMark, 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 resolution.

For engineers reviewing the R5F526TAAGFM#10 datasheet, R5F526TAAGFM#10 pinout, R5F526TAAGFM#10 application, or R5F526TAAGFM#10 equivalent, this MCU supports IEC60730-compliant safety functions, Trusted Secure IP Lite encryption (AES-128/256), dual-bank flash for seamless firmware updates, and event-linked peripheral coordination via ELC - critical for real-time motor timing, fault response, and secure firmware integrity in embedded power electronics.

Technical Context

The R5F526TAAGFM#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 during interrupt-driven motor control loops. Its clock system integrates PLL-synthesized 120 MHz ICLK, independent IWDT oscillator (120 kHz), and configurable PCLK domains (PCLKA up to 120 MHz, PCLKB/C/D at 60–120 MHz) enabling precise timing separation between CPU, PWM, ADC, and communication peripherals.

Peripheral coordination is managed through the Event Link Controller (ELC), which interconnects 183 internal signals - allowing MTU3d timers, GPTWa PWM units, S12ADH ADCs, and CMPCa comparators to trigger operations without CPU intervention. This architecture enables synchronized dead-time insertion, phase-shifted PWM updates, and simultaneous sampling across three A/D units - essential for vector-controlled PMSM/BLDC inverters.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TAAGFM#10?

The R5F526TAAGFM#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark - measured under standard conditions with the RXv3 core executing the EEMBC benchmark. This performance enables real-time execution of complex field-oriented control (FOC) algorithms with sub-microsecond loop times, directly supporting high-speed PMSM and BLDC motor applications without external co-processors.

Does the R5F526TAAGFM#10 support CAN FD, and what standard does it comply with?

Yes, the R5F526TAAGFM#10 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames at data rates up to 5 Mbps. This allows high-bandwidth diagnostics, firmware updates, and real-time motor status reporting in automotive and industrial networks - with built-in error handling, message filtering, and flexible bit timing configuration accessible via the CANFD register set.

How many A/D converter channels does the R5F526TAAGFM#10 support, and what is its sampling capability?

The R5F526TAAGFM#10 supports 22 total A/D channels across three S12ADH units (4+4+14), with simultaneous sampling capability across all units. Each channel provides 12-bit resolution and a minimum conversion time of 0.9 µs at 60 MHz ADCLK - enabling synchronized acquisition of three-phase currents and DC-link voltage for accurate torque estimation in motor control applications.
