Renesas R5F526TBCGND#50

Overview

R5F526TBCGND#50 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring a 120 MHz CPU core (709 CoreMark), 512 KB on-chip code flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD interface, and hardware-accelerated 3-phase/5-phase complementary PWM generation with 260 ps HRPWM timing resolution.

For engineers reviewing the R5F526TBCGND#50 datasheet, R5F526TBCGND#50 pinout, R5F526TBCGND#50 application, or R5F526TBCGND#50 equivalent, key selection criteria include its dual-bank flash architecture enabling background programming, IEC60730-compliant safety features (oscillation-stop detection, RAM test assist, CRC calculator), Trusted Secure IP Lite encryption (AES-128/256), and dedicated motor control peripherals including MTU3d (9-channel 16-bit timer), GPTWa (8-channel 32-bit PWM), and CMPCa (6-channel analog comparator).

Technical Context

The R5F526TBCGND#50 implements the RXv3 CPU core with single-cycle instruction execution, 32×32→64-bit multiplier, IEEE 754-compliant single-precision FPU, and collective register bank save for fast context switching. Its clock system integrates an 8–24 MHz external crystal oscillator, internal 240 kHz LOCO and 16/18/20 MHz HOCO, and PLL supporting up to 120 MHz ICLK with independent PCLKA/PCLKB/PCLKC/PCLKD domains.

Motor control execution relies on tightly coupled peripherals: MTU3d provides 3-phase complementary PWM with automatic dead-time insertion and phase-counting mode; GPTWa delivers high-resolution waveform control with synchronous start/stop across channels; HRPWM refines GPTW0–GPTW3 outputs to 260 ps minimum edge placement resolution; and ELC enables interrupt-free inter-module event linking (e.g., timer-triggered ADC conversion).

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TBCGND#50?

The R5F526TBCGND#50 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance level is enabled by the RXv3 CPU core's single-cycle instruction execution, 32×32→64-bit hardware multiplier, and efficient pipeline design-making it suitable for real-time motor control algorithms requiring deterministic timing and high computational throughput.

Does the R5F526TBCGND#50 support CAN FD, and what standard does it comply with?

Yes, the R5F526TBCGND#50 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frame formats at data rates up to 5 Mbps. This enables high-bandwidth diagnostics, firmware updates, and distributed control messaging in industrial automation networks where legacy CAN 2.0B bandwidth limitations are insufficient.

What PWM resolution does the R5F526TBCGND#50 provide, and how is it achieved?

The R5F526TBCGND#50 delivers 260 ps minimum edge placement resolution via its High-Resolution PWM (HRPWM) circuit, which refines outputs from GPTW0–GPTW3 timers. This is achieved through dedicated timing logic synchronized to the 120 MHz system clock, enabling precise dead-time control critical for SiC/GaN-based inverter designs where nanosecond-level timing prevents shoot-through failures.

How does the R5F526TBCGND#50 support IEC60730 functional safety compliance?

The R5F526TBCGND#50 includes multiple IEC60730 Class B support features: oscillation-stop detection for main clock failure, RAM test assist via DOC, CRC calculator (CRCA) for memory/data integrity, register write protection, and analog input disconnection detection in the S12ADH ADC. These features collectively enable systematic safety mechanisms required for certification in motor-driven appliances and industrial equipment.

What package type and thermal rating does the R5F526TBCGND#50 use?

The R5F526TBCGND#50 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), making it suitable for under-hood automotive ancillaries and industrial environments with elevated ambient temperatures and thermal cycling stress.
