Renesas R5F526TBCDNE#30

Overview

R5F526TBCDNE#30 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring a 120 MHz CPU core, 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 timing resolution.

For engineers reviewing the R5F526TBCDNE#30 datasheet, R5F526TBCDNE#30 pinout, R5F526TBCDNE#30 application, or R5F526TBCDNE#30 equivalent, this MCU delivers deterministic real-time control for brushless DC and permanent magnet synchronous motor drives, supports IEC 60730 Class B safety compliance via built-in self-test functions, and integrates Trusted Secure IP Lite for AES-128/256 encryption and true random number generation.

Technical Context

The R5F526TBCDNE#30 implements the RXv3 CPU core with single-cycle instruction execution, 113 instructions (including DSP and floating-point), and a collective register bank save function enabling fast context switching. It integrates dual-bank flash for safe firmware updates and supports simultaneous sampling across three 12-bit A/D converter units with programmable gain amplifiers.

Its timer subsystem combines eight 32-bit GPTWa channels, nine 16-bit MTU3d channels, and four HRPWM channels synchronized to PCLKC at up to 120 MHz - enabling precise dead-time compensation, phase-counting, and non-overlapping waveform generation for 3-phase inverters without CPU intervention via ELC event linking.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TBCDNE#30?

The R5F526TBCDNE#30 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, 32-bit multiplier/divider, and barrel shifter - all verified in the official Renesas R01DS0407EJ0120 datasheet. The R5F526TBCDNE#30 sustains full-speed operation across its 512 KB flash and 64 KB SRAM without wait states.

Does the R5F526TBCDNE#30 support CAN FD, and what standard does it comply with?

Yes, the R5F526TBCDNE#30 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames at data rates up to 5 Mbps. Its CAN FD interface includes dedicated transmit/receive buffers, error counters, and loopback self-test modes - all documented in Section 1.1 of the R01DS0407EJ0120 datasheet. The R5F526TBCDNE#30 uses differential CTX0/CRX0 pins for robust noise immunity in motor control environments.

How many A/D converter channels does the R5F526TBCDNE#30 provide, and what is their resolution?

The R5F526TBCDNE#30 provides 22 total channels across three 12-bit A/D converter units (S12ADH): Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels), all with 12-bit resolution and 0.9 µs minimum conversion time at 60 MHz ADCLK. Each unit includes sample-and-hold circuits, programmable gain amplifiers, and digital comparison logic - confirmed in Table 1.1 and Section 1.1 of the R01DS0407EJ0120 datasheet. The R5F526TBCDNE#30 supports simultaneous sampling across all three units for multi-sensor acquisition.

What PWM capabilities does the R5F526TBCDNE#30 offer for motor control applications?

The R5F526TBCDNE#30 delivers comprehensive motor control PWM: eight 32-bit GPTWa channels, nine 16-bit MTU3d channels, and four HRPWM channels with 260 ps minimum resolution. It supports 10 single-phase, 3 three-phase, or 2 five-phase complementary PWM outputs with automatic dead-time insertion and phase-counting mode - all synchronized to PCLKC at 120 MHz. These capabilities are detailed in Sections 1.1 and 2.3 of the R01DS0407EJ0120 datasheet. The R5F526TBCDNE#30 uses these resources to generate non-overlapping gate drive signals for SiC/GaN inverters.

Is the R5F526TBCDNE#30 qualified for IEC 60730 safety compliance, and which features enable this?

Yes, the R5F526TBCDNE#30 includes hardware features certified for IEC 60730 Class B compliance: oscillation-stop detection, independent watchdog timer (IWDTa) with window function, RAM test assist (DOC), CRC calculator (CRCA), memory protection unit (MPU), and register write protection. These are explicitly listed in the "Useful functions for IEC60730 compliance" section of the R01DS0407EJ0120 datasheet. The R5F526TBCDNE#30 leverages these integrated functions to reduce external safety component count in motor control designs.
