Renesas R5F526TAADFM#30

Overview

R5F526TAADFM#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 functional safety compliance and operates across –40°C to +85°C.

For engineers reviewing the R5F526TAADFM#30 datasheet, R5F526TAADFM#30 pinout, R5F526TAADFM#30 application, or R5F526TAADFM#30 equivalent, key selection criteria include its 120 MHz GPTWa timer with 3-phase/5-phase complementary PWM, dual-bank flash for safe firmware updates, Trusted Secure IP Lite encryption, and hardware-accelerated trigonometric functions (TFUv2) for real-time motor vector control.

Technical Context

The R5F526TAADFM#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. Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator - enabling independent peripheral clock domains (PCLKA up to 120 MHz, PCLKB/C/D at up to 60–120 MHz).

Motor control is enabled by tightly coupled peripherals: MTU3d (9-channel 16-bit timer) and GPTWa (8-channel 32-bit timer) support synchronous PWM generation, dead-time insertion, and A/D trigger synchronization; HRPWM extends GPTW0–GPTW3 output resolution to 260 ps; S12ADH provides three 12-bit A/D units with simultaneous sampling across 22 channels; CMPCa offers six analog comparators with programmable reference inputs.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TAADFM#30?

The R5F526TAADFM#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark points under benchmark conditions. This performance stems from its RXv3 CPU core with single-cycle instruction execution, on-chip FPU, and optimized memory subsystem enabling no-wait access to both 512 KB flash and 64 KB SRAM - all confirmed in the official R01DS0407EJ0120 datasheet Rev.1.20.

Does the R5F526TAADFM#30 support CAN FD, and what standard does it comply with?

Yes, the R5F526TAADFM#30 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames with data rates up to 5 Mbps. The module includes dedicated message RAM, error counters, and loopback/self-test modes - all documented in Section 1.1 and Chapter 32 of the R01DS0407EJ0120 datasheet.

What PWM resolution does the R5F526TAADFM#30 achieve, and how is it implemented?

The R5F526TAADFM#30 achieves a minimum PWM edge resolution of 260 ps using its High-Resolution PWM (HRPWM) circuit, which enhances the timing precision of GPTW0–GPTW3 outputs. This is realized by interpolating between PCLKC cycles (up to 120 MHz) and is explicitly specified in the "High resolution PWM (HRPWM)" section of the R01DS0407EJ0120 datasheet Rev.1.20.

How many A/D converter channels does the R5F526TAADFM#30 support, and what is their architecture?

The R5F526TAADFM#30 supports up to 22 channels across three independent 12-bit S12ADH units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels), each with dedicated sample-and-hold circuits. This configuration enables true simultaneous sampling - a capability verified in Table 1.2 and Section 18.1 of the R01DS0407EJ0120 datasheet.

Is the R5F526TAADFM#30 qualified for IEC60730 functional safety, and which features enable compliance?

Yes, the R5F526TAADFM#30 includes multiple hardware features supporting IEC60730 Class B compliance: oscillation-stop detection, A/D disconnection detection, clock accuracy measurement, independent watchdog timer (IWDTa) with window function, RAM test assist (DOC), CRCA, and register write protection - all explicitly listed under "Useful functions for IEC60730 compliance" in the R01DS0407EJ0120 datasheet Rev.1.20.
