Renesas R5F526TBBGND#50

Overview

R5F526TBBGND#50 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.

For engineers reviewing the R5F526TBBGND#50 datasheet, R5F526TBBGND#50 pinout, R5F526TBBGND#50 application, or R5F526TBBGND#50 equivalent, this MCU targets high-precision timing-critical systems requiring simultaneous sampling across multiple analog channels, deterministic real-time interrupt response, secure firmware execution via Trusted Secure IP Lite, and IEC60730-compliant functional safety features.

Technical Context

The R5F526TBBGND#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. It integrates dual-bank flash enabling background programming while executing from alternate bank, and supports little-endian or big-endian data arrangement.

Its clock system combines an 8–24 MHz external crystal oscillator with PLL synthesis to generate up to 120 MHz ICLK, while independent PCLKA (120 MHz), PCLKB (60 MHz), PCLKC (120 MHz), and PCLKD (60 MHz) domains enable precise peripheral clock gating and domain-specific timing control for motor control peripherals like MTU3d and GPTWa.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TBBGND#50?

The R5F526TBBGND#50 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, on-chip FPU, and optimized memory subsystem enabling deterministic real-time response critical for motor control loops. The R5F526TBBGND#50 maintains this speed across its full operating voltage range (2.7–5.5 V).

Does the R5F526TBBGND#50 support CAN FD, and what standard does it comply with?

Yes, the R5F526TBBGND#50 integrates a CAN FD module compliant with ISO11898-1:2015, supporting both standard (11-bit) and extended (29-bit) frame formats at data rates up to 5 Mbps. It includes dedicated TX/RX pins, message RAM with flexible filtering, and error handling consistent with automotive and industrial CAN FD requirements. The R5F526TBBGND#50 requires no external transceiver for physical layer signaling.

How many analog-to-digital converter channels does the R5F526TBBGND#50 provide, and what is their resolution?

The R5F526TBBGND#50 includes a 12-bit S12ADH analog-to-digital converter with 21 total input channels distributed across three sample-and-hold units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels). Minimum conversion time is 0.9 µs per channel when ADCLK runs at 60 MHz. The R5F526TBBGND#50 supports simultaneous sampling across all three units for phase-aligned current/voltage measurement in 3-phase motor control.

What PWM capabilities does the R5F526TBBGND#50 offer for motor control applications?

The R5F526TBBGND#50 provides three complementary PWM subsystems: 8-channel 32-bit GPTWa, 9-channel 16-bit MTU3d, and 4-channel HRPWM with 260 ps minimum timing resolution. It supports single-phase (10 outputs), 3-phase (3 outputs), and 5-phase (2 outputs) complementary PWM modes with hardware dead-time insertion, automatic waveform inversion, and ELC-synchronized ADC triggering. These features make the R5F526TBBGND#50 ideal for inverter gate driver control with minimal software overhead.

Is the R5F526TBBGND#50 qualified for industrial temperature range, and what package does it use?

Yes, the R5F526TBBGND#50 is rated for –40°C to +105°C (G-version) and housed in the PLQP0100KB-B package: a 100-pin LQFP with 14 mm × 14 mm body, 0.5 mm pitch, and exposed thermal pad. This package supports high-power dissipation in motor control applications and is compatible with standard reflow soldering profiles. The R5F526TBBGND#50 meets JEDEC J-STD-020 moisture sensitivity level 3 requirements.
