Overview

R5F526TBAGFP#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 code flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD interface, and hardware-accelerated 3-phase complementary PWM with dead-time control. It supports IEC60730 safety compliance and operates across –40°C to +85°C.

For engineers reviewing the R5F526TBAGFP#30 datasheet, R5F526TBAGFP#30 pinout, R5F526TBAGFP#30 application, or R5F526TBAGFP#30 equivalent, key selection criteria include its 120 MHz GPTWa timer with 10-channel single-phase complementary PWM, 260 ps HRPWM resolution, dual-bank flash for safe firmware updates, Trusted Secure IP Lite encryption, and 83-pin general-purpose I/O with 5-V tolerance - all critical for real-time motor drive firmware and functional safety certification.

Technical Context

The R5F526TBAGFP#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 in interrupt-heavy motor control loops. Its clock system integrates PLL-based 120 MHz ICLK, independent IWDT oscillator (120 kHz), and configurable peripheral clocks (PCLKA up to 120 MHz, PCLKB/C/D at derived frequencies) enabling precise timing separation between CPU, PWM, ADC, and communication modules.

Hardware safety features include MPU-enforced memory protection, Trusted Memory (TM) for secure boot code isolation, CRCA for CRC-32/8 computation, oscillation-stop detection, and register write protection - all aligned with IEC60730 Class B requirements. The ELC enables event-triggered peripheral coordination without CPU intervention, allowing synchronized A/D conversion start, PWM update, and fault response in sub-microsecond latency.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TBAGFP#30?

The R5F526TBAGFP#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark. This performance level is measured under standard conditions using the EEMBC CoreMark benchmark and reflects the efficiency of the RXv3 CPU core with its single-cycle instruction execution and integrated FPU. The R5F526TBAGFP#30 sustains this speed across its full temperature range (–40°C to +85°C) with no wait states on code flash access.

Does the R5F526TBAGFP#30 support CAN FD, and what standard does it comply with?

Yes, the R5F526TBAGFP#30 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames. It operates at up to 5 Mbps in the data phase and includes built-in message filtering, FIFO buffering, and error handling. This capability enables high-bandwidth diagnostics and firmware updates in automotive and industrial networks - a core feature confirmed in the R01DS0407EJ0120 datasheet for the R5F526TBAGFP#30.

What is the resolution and timing precision of the High-Resolution PWM (HRPWM) in the R5F526TBAGFP#30?

The R5F526TBAGFP#30 provides 260 ps minimum edge placement resolution for its HRPWM outputs on GPTW0–GPTW3 channels. This precision is achieved by leveraging the 120 MHz system clock and dedicated timing circuitry, enabling sub-nanosecond control of SiC/GaN gate drivers. The R5F526TBAGFP#30 datasheet specifies this value explicitly for products with 64 KB SRAM, which matches the R5F526TBAGFP#30 configuration.

How does the R5F526TBAGFP#30 support IEC60730 Class B compliance?

The R5F526TBAGFP#30 includes dedicated hardware for IEC60730 Class B: oscillation-stop detection, RAM test assist (DOC), CRCA for CRC-32/8, register write protection, independent watchdog timer (IWDT) with window function, and self-diagnostic A/D converter functions. These features are documented in the R01DS0407EJ0120 datasheet as part of the RX26T Group's safety architecture - eliminating the need for external monitoring ICs in certified motor control designs.

What package type and pin count does the R5F526TBAGFP#30 use?

The R5F526TBAGFP#30 uses the PLQP0100KB-B package: a 100-pin LQFP with 14 × 14 mm body size and 0.5 mm pitch. This package supports 83 general-purpose I/O pins, including 5-V tolerant inputs, open-drain outputs, and large-current drive capability. The pinout and mechanical dimensions are fully specified in the R01DS0407EJ0120 datasheet for the R5F526TBAGFP#30.
