Renesas R5F526TBAGND#30

Overview

R5F526TBAGND#30 from Renesas is a 32-bit RXv3 microcontroller designed for motor control and industrial inverter applications, featuring 120 MHz operation, 512 KB on-chip flash memory, 64 KB SRAM, integrated CAN FD interface, and hardware-accelerated 3-phase complementary PWM generation with dead-time control.

For engineers reviewing the R5F526TBAGND#30 datasheet, R5F526TBAGND#30 pinout, R5F526TBAGND#30 application, or R5F526TBAGND#30 equivalent, key selection considerations include its 100-pin LFQFP package, dual-bank flash architecture enabling background programming, 260 ps HRPWM timing resolution, IEC60730 safety support, and Trusted Secure IP Lite encryption engine.

Technical Context

The R5F526TBAGND#30 implements the RXv3 CPU core with single-cycle instruction execution at 120 MHz, supporting IEEE 754-compliant single-precision FPU and collective register bank save for fast context switching. Its clock system integrates PLL, 240-kHz LOCO, and 16/18/20-MHz HOCO oscillators, with independent 120-kHz IWDT-dedicated oscillator for functional safety.

Peripheral coordination is managed via Event Link Controller (ELC), enabling 183 internal event signals to trigger timer starts/stops, A/D conversion triggers, or port output changes without CPU intervention-critical for deterministic motor control timing and low-latency response in inverter gate drive sequences.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TBAGND#30?

The R5F526TBAGND#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance stems from the RXv3 CPU core's single-cycle instruction execution, 32-bit multiplier/divider, and barrel shifter-enabling deterministic real-time motor control loops. The R5F526TBAGND#30 sustains this speed across its full 512 KB flash and 64 KB SRAM without wait states.

Does the R5F526TBAGND#30 support IEC60730 Class B compliance out of the box?

Yes, the R5F526TBAGND#30 includes dedicated hardware for IEC60730 Class B compliance: oscillation-stop detection, RAM test assist via DOC, CRCA for data integrity, register write protection, and independent watchdog timer with window function. These features are documented in the R01DS0407EJ0120 datasheet and require no external components-reducing certification effort for R5F526TBAGND#30-based designs.

What PWM resolution does the R5F526TBAGND#30 achieve, and how is it implemented?

The R5F526TBAGND#30 delivers a minimum PWM timing resolution of 260 ps using its High-Resolution PWM (HRPWM) circuit, which controls rising/falling edges of GPTWa-generated waveforms at 120 MHz. This is achieved through dedicated fine-delay logic synchronized to the PCLKC peripheral clock-enabling precise dead-time insertion and gate-drive skew compensation critical for high-efficiency SiC/GaN inverter designs using the R5F526TBAGND#30.

How many A/D converter channels does the R5F526TBAGND#30 support, and what is their configuration?

The R5F526TBAGND#30 supports 22 total channels across three 12-bit S12ADH units: Unit 0 (4 channels, 3 sample-and-hold circuits), Unit 1 (4 channels, 3 sample-and-hold circuits), and Unit 2 (14 channels). This configuration enables simultaneous sampling of current/voltage feedback in multi-phase motor control-leveraging ELC-triggered conversion start for cycle-aligned acquisition relative to PWM center points in R5F526TBAGND#30 applications.

What is the package type and thermal specification of the R5F526TBAGND#30?

The R5F526TBAGND#30 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 the D-version operating temperature range of –40°C to +85°C, with thermal resistance θJA of 32°C/W (JEDEC JESD51-7 standard). This package supports robust thermal dissipation in compact inverter modules where the R5F526TBAGND#30 manages high-frequency switching losses.
