Renesas R5F526TFAGFL#30

Overview

R5F526TFAGFL#30 from Renesas is a 32-bit RXv3 core microcontroller optimized for motor control, featuring 120 MHz operation, 512 KB on-chip code flash, 64 KB SRAM, 16 KB data flash, and integrated high-resolution PWM (260 ps min. resolution) with 3-phase/5-phase complementary output capability. It supports CAN FD, I3C, RIIC, RSPI, and RSCI interfaces, and includes dual 12-bit ADC units with simultaneous sampling for real-time current/voltage sensing in inverter drives.

For engineers reviewing the R5F526TFAGFL#30 datasheet, R5F526TFAGFL#30 pinout, R5F526TFAGFL#30 application, or R5F526TFAGFL#30 equivalent, key selection considerations include its 100-pin LFQFP package, 64 KB RAM configuration enabling full GPTWa timer set and dual ADC units, Trusted Secure IP Lite encryption, IEC60730 safety features, and dedicated HRPWM timing control for precision motor phase alignment.

Technical Context

The R5F526TFAGFL#30 implements the RXv3 CPU core with single-cycle instruction execution, 709 CoreMark at 120 MHz, and support for collective register bank save-enabled only in 64 KB RAM variants. Its clock system integrates PLL with 8–24 MHz crystal input, 240 kHz LOCO, and 120 kHz IWDT oscillator, with independent PCLKA/PCLKC domains enabling 120 MHz peripheral operation for GPTWa, MTU3d, and HRPWM.

Motor control architecture centers on synchronized timer subsystems: 32-bit GPTWa (8 channels), MTU3d (9 channels), and HRPWM (4 channels) sharing PCLKC reference clocks; ELC enables event-triggered, CPU-free coordination between timers, ADC triggers, and comparator outputs-critical for deterministic field-oriented control loops.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TFAGFL#30?

The R5F526TFAGFL#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark under those conditions. This performance stems from the RXv3 CPU core's single-cycle instruction execution, collective register bank save, and efficient memory subsystem-enabling real-time motor control loops with minimal jitter. The R5F526TFAGFL#30 sustains this speed across its full 512 KB flash and 64 KB SRAM with zero wait states.

Does the R5F526TFAGFL#30 support CAN FD, and what standard does it comply with?

Yes, the R5F526TFAGFL#30 integrates a CAN FD module compliant with ISO11898-1:2015, supporting both standard and extended frames. It enables data rates up to 5 Mbps for high-bandwidth diagnostics and networked drive control-critical for automotive EPS and industrial automation. The R5F526TFAGFL#30 implements full protocol handling in hardware, including bit rate switching and error confinement, without CPU overhead.

How many ADC channels does the R5F526TFAGFL#30 support, and what is their configuration?

The R5F526TFAGFL#30 supports 22 total ADC input channels across three 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 dual-unit structure enables true simultaneous sampling of up to six analog signals-essential for three-phase current reconstruction in motor control. The R5F526TFAGFL#30 achieves 0.9 µs minimum conversion time per channel at 60 MHz ADCLK.

What safety certifications and self-test features does the R5F526TFAGFL#30 include for IEC60730 compliance?

The R5F526TFAGFL#30 includes dedicated hardware for IEC60730 Class B compliance: main clock oscillation stop detection, ADC disconnection monitoring, RAM test assist via DOC, CRC calculator (CRCA), and register write protection. These features operate autonomously without CPU involvement-reducing software certification burden. The R5F526TFAGFL#30 also supports safe boot via Trusted Memory (TM) and provides documented failure modes for each safety mechanism.

What is the package type and thermal specification of the R5F526TFAGFL#30?

The R5F526TFAGFL#30 uses the PLQP0100KB-B package: a 100-pin LFQFP with 14 mm × 14 mm body, 0.5 mm pitch, and exposed thermal pad. It is rated for operation from –40°C to +105°C (G-version), meeting industrial and automotive under-hood temperature requirements. The package supports reflow soldering per J-STD-020 and includes moisture sensitivity level (MSL) 3 rating.
