Renesas R5F526TBCGNE#50

Overview

R5F526TBCGNE#50 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control, featuring a 120 MHz CPU core, 512 KB on-chip code flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD interface, and high-resolution PWM with 260 ps timing resolution. It supports IEC60730 safety compliance and targets inverter-driven industrial motors and servo systems.

For engineers reviewing the R5F526TBCGNE#50 datasheet, R5F526TBCGNE#50 pinout, R5F526TBCGNE#50 application, or R5F526TBCGNE#50 equivalent, key selection criteria include its 100-pin PLQP0100KB-B package, dual-bank flash architecture enabling background programming, 3-phase/5-phase complementary PWM capability, and Trusted Secure IP Lite encryption support for firmware integrity.

Technical Context

The R5F526TBCGNE#50 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. Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator - enabling independent peripheral clock domains (PCLKA up to 120 MHz, PCLKB up to 60 MHz).

Motor control is enabled by tightly coupled peripherals: GPTWa (8-channel 32-bit timer) and MTU3d (9-channel 16-bit timer) both synchronized to PCLKC for precise PWM generation; HRPWM (4 channels) overlays sub-nanosecond timing control onto GPTW outputs; and ELC links A/D conversion triggers directly to timer events without CPU intervention.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TBCGNE#50?

The R5F526TBCGNE#50 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark points under benchmark conditions. This performance level enables execution of complex motor control algorithms such as field-oriented control (FOC) and sensorless estimation within tight real-time deadlines. The RXv3 CPU core's single-cycle instruction execution and integrated FPU further enhance deterministic computation for embedded motor applications.

Does the R5F526TBCGNE#50 support CAN FD, and what standard does it comply with?

Yes, the R5F526TBCGNE#50 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames at data rates up to 5 Mbps. This enables high-bandwidth diagnostics, firmware updates, and real-time control messaging in automotive and industrial networks - a key differentiator from legacy CAN 2.0 implementations in the RX26T family.

What package type and pin count does the R5F526TBCGNE#50 use?

The R5F526TBCGNE#50 uses the PLQP0100KB-B package: a 100-pin low-profile quad flat package (LQFP) with 14 × 14 mm body size and 0.5 mm lead pitch. This package provides 83 general-purpose I/O pins, including 5-V tolerant inputs, open-drain outputs, and large-current drive capability - optimized for direct interface with gate drivers and sensors in motor control boards.

How does the R5F526TBCGNE#50 support IEC60730 functional safety compliance?

The R5F526TBCGNE#50 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stop detection, RAM test assist (DOC), CRC calculator (CRCA), register write protection, and self-diagnostic A/D functions. These reduce software overhead and verification effort for safety-critical motor control applications - confirmed in Renesas' official safety manual R01UL0247EJ0200.

What is the resolution and timing capability of the HRPWM in the R5F526TBCGNE#50?

The R5F526TBCGNE#50 features a High-Resolution PWM (HRPWM) block with 260 ps minimum timing resolution when operating at 120 MHz. This capability applies to GPTW0 through GPTW3 outputs and enables precise dead-time adjustment, reduced torque ripple, and improved efficiency in high-frequency inverter designs - a specification explicitly validated in the R01DS0407EJ0120 datasheet.
