Renesas R5F526TBBGFL#30

Overview

R5F526TBBGFL#30 from Renesas is a 32-bit RXv3 microcontroller designed for high-performance motor control and industrial inverter applications. It operates at up to 120 MHz, integrates 512 KB code flash, 64 KB SRAM, 16 KB data flash, dual-bank flash architecture, and supports CAN FD, 3-phase/5-phase complementary PWM, and 260-ps resolution HRPWM. Its on-chip FPU, MPU, and IEC60730-compliant safety features make it suitable for real-time closed-loop motor drives.

For engineers reviewing the R5F526TBBGFL#30 datasheet, R5F526TBBGFL#30 pinout, R5F526TBBGFL#30 application, or R5F526TBBGFL#30 equivalent, key selection criteria include 120-MHz PWM timing precision, integrated analog front-end (12-bit ADC × 3 units, 6-channel comparator, 2-channel DAC), CAN FD interface compliance with ISO11898-1:2015, and Trusted Secure IP Lite encryption support for firmware integrity.

Technical Context

The R5F526TBBGFL#30 implements the RXv3 CPU core with single-cycle instruction execution, 113 instructions, IEEE 754-compliant single-precision FPU, and collective register bank save for fast context switching. Its clock system combines an 8–24 MHz external crystal with PLL synthesis to deliver 120 MHz ICLK, while PCLKA/PCLKC run at up to 120 MHz for GPTW/HRPWM/MTU modules.

It integrates three independent 12-bit A/D converter units (S12ADH) - two with 3-channel sample-and-hold and one with 14 channels - synchronized via ELC-triggered start signals from GPTW or MTU timers. The HRPWM circuit achieves 260 ps minimum timing resolution by controlling GPTW0–GPTW3 output edges with sub-cycle precision.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TBBGFL#30?

The R5F526TBBGFL#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance stems from its RXv3 CPU core with single-cycle instruction execution, 32-bit multiplier/divider, and barrel shifter. The R5F526TBBGFL#30 sustains this speed across code flash and SRAM with no wait states, enabling deterministic real-time motor control loops.

Does the R5F526TBBGFL#30 support CAN FD, and which standard does it comply with?

Yes, the R5F526TBBGFL#30 integrates a CAN FD module compliant with ISO11898-1:2015, supporting both standard and extended frames at data rates up to 5 Mbps. It includes bit-rate switching, flexible data-length payloads, and error confinement features required for automotive and industrial networked motor control. The R5F526TBBGFL#30 uses this interface for high-integrity diagnostics and host coordination in OBC and PLC applications.

How many A/D converter units does the R5F526TBBGFL#30 include, and what is their configuration?

The R5F526TBBGFL#30 includes three independent 12-bit S12ADH A/D converter units: Unit 0 (4 channels, 3 sample-and-hold circuits), Unit 1 (4 channels, 3 sample-and-hold circuits), and Unit 2 (14 channels). This configuration enables simultaneous sampling of multiple analog signals - such as phase currents, DC-link voltage, and temperature - without inter-channel skew. The R5F526TBBGFL#30 supports ELC-triggered start for precise synchronization with PWM timer events.

What is the resolution and timing capability of the HRPWM in the R5F526TBBGFL#30?

The R5F526TBBGFL#30 features a 4-channel High-Resolution PWM (HRPWM) circuit that controls rising/falling edges of GPTW0–GPTW3 outputs with a minimum resolution of 260 ps when operating at 120 MHz. This enables sub-nanosecond dead-time tuning and phase alignment critical for SiC/GaN-based inverters. The R5F526TBBGFL#30 achieves this via dedicated time-base interpolation logic, not software-based delay loops.

Is the R5F526TBBGFL#30 qualified for industrial temperature range operation?

Yes, the R5F526TBBGFL#30 is rated for operation from –40°C to +105°C (G-version), validated per JEDEC JESD22-A104 and JESD22-A108 standards. Its thermal sensor provides on-die temperature measurement with ±1.0°C relative precision, and the analog peripherals (ADC, DAC, comparator) maintain specified accuracy across this full range. The R5F526TBBGFL#30 is packaged in PLQP0100KB-B, qualified for industrial reflow profiles and long-term reliability in harsh environments.
