Renesas R5F526TFADNE#30

Overview

R5F526TFADNE#30 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 flash memory with dual-bank support, 64 KB SRAM, 16 KB data flash (100,000 write/erase cycles), integrated CAN FD interface (ISO 11898-1:2015), and hardware-accelerated 3-phase complementary PWM generation - deployed in HVAC compressors and servo drive systems.

For engineers reviewing the R5F526TFADNE#30 datasheet, R5F526TFADNE#30 pinout, R5F526TFADNE#30 application, or R5F526TFADNE#30 equivalent, key selection criteria include its 120 MHz GPTWa timer with 10-channel single-phase complementary PWM, 260 ps HRPWM timing resolution, IEC60730-compliant self-test features (oscillation-stop detection, RAM test assist, CRC calculator), and Trusted Secure IP Lite encryption (AES-128/256, TRNG).

Technical Context

The R5F526TFADNE#30 implements the RXv3 CPU core with collective register bank save, MPU, and IEEE 754-compliant single-precision FPU. Its clock system integrates an 8–24 MHz external crystal oscillator, internal 240 kHz LOCO and 16/18/20 MHz HOCO, and PLL for 120 MHz ICLK generation - with independent PCLKA (120 MHz), PCLKB (60 MHz), PCLKC (120 MHz), and PCLKD (60 MHz) domains enabling precise peripheral timing.

Motor control execution relies on tightly coupled peripherals: MTU3d (9-channel 16-bit timer) and GPTWa (8-channel 32-bit timer) deliver synchronized 3-phase PWM with automatic dead-time insertion and phase-counting mode; HRPWM extends GPTW0–GPTW3 output timing resolution to 260 ps; S12ADH (12-bit ADC) provides simultaneous sampling across three units (4+4+14 channels) with programmable gain amplifiers and analog input disconnection detection.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TFADNE#30?

The R5F526TFADNE#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency with collective register bank save and single-cycle instruction execution. The R5F526TFADNE#30 sustains this performance across its full voltage range (2.7–5.5 V) and temperature range (–40°C to +85°C), making it suitable for demanding real-time motor control tasks where deterministic timing is critical.

Does the R5F526TFADNE#30 support CAN FD, and what standard does it comply with?

Yes, the R5F526TFADNE#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 in FD mode. It includes dedicated TX/RX pins (CANFD_TX/CANFD_RX), message buffering, and error handling logic. The R5F526TFADNE#30's CAN FD implementation enables high-bandwidth communication in industrial networks such as HVAC system controllers and distributed servo drives without requiring external transceivers beyond the PHY layer.

How many channels does the 12-bit A/D converter have on the R5F526TFADNE#30, and what sampling capability does it offer?

The R5F526TFADNE#30 features the S12ADH 12-bit A/D converter with 22 total input channels distributed across three units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels). It supports simultaneous sampling across all three units using dedicated sample-and-hold circuits - critical for accurate current/voltage acquisition in 3-phase motor control. The R5F526TFADNE#30 achieves 0.9 µs minimum conversion time per channel when ADCLK runs at 60 MHz.

What is the HRPWM resolution of the R5F526TFADNE#30, and which timers does it enhance?

The R5F526TFADNE#30 provides High-Resolution PWM (HRPWM) with a minimum timing resolution of 260 ps, applied exclusively to the GPTW0 through GPTW3 output channels. This capability extends the base GPTWa timer's 120 MHz counter resolution by inserting fine-grained delays in the PWM edge timing path. The R5F526TFADNE#30 uses HRPWM to minimize dead-time distortion and improve torque smoothness in PMSM and BLDC motor drives where nanosecond-level timing control is required.

Is the R5F526TFADNE#30 certified for IEC60730 functional safety, and what built-in features support compliance?

The R5F526TFADNE#30 includes hardware features aligned with IEC60730 Class B requirements, including oscillation-stoppage detection, independent watchdog timer (IWDT) with window function, clock frequency accuracy measurement, RAM test assist via DOC, CRC calculator (CRCA), and register write protection. While the R5F526TFADNE#30 itself is not pre-certified, these integrated capabilities reduce external component count and simplify certification efforts for end equipment such as motor drives and HVAC controllers.
