Renesas R5F526TFBGND#30

Overview

R5F526TFBGND#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 flash memory, 64 KB SRAM, 16 KB data flash, integrated CAN FD interface, and hardware-accelerated 3-phase PWM generation with dead-time control.

For engineers reviewing the R5F526TFBGND#30 datasheet, R5F526TFBGND#30 pinout, R5F526TFBGND#30 application, or R5F526TFBGND#30 equivalent, key selection criteria include its 120 MHz real-time PWM timing resolution (260 ps minimum), dual-bank flash for safe firmware updates, IEC60730-compliant safety features, and support for simultaneous sampling across three 12-bit A/D units - critical for high-fidelity motor current sensing.

Technical Context

The R5F526TFBGND#30 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 in real-time motor control loops. Its clock system supports PLL-synthesized 120 MHz operation using an external 8–24 MHz crystal or internal HOCO.

Peripheral timing is segmented across four PCLK domains: PCLKA (up to 120 MHz) drives MTU3d, GPTWa, and CAN FD; PCLKC (up to 120 MHz) clocks HRPWM and timer reference clocks; PCLKB (up to 60 MHz) serves SCI, RIIC, and S12ADH; and PCLKD (up to 60 MHz) feeds the A/D converter's ADCLK - enabling precise, independent domain optimization.

FAQ

What is the maximum operating frequency and CPU architecture of the R5F526TFBGND#30?

The R5F526TFBGND#30 operates at a maximum frequency of 120 MHz using the 32-bit RXv3 CPU core. It delivers 709 CoreMark performance and supports single-cycle instruction execution, IEEE 754-compliant single-precision floating-point operations, and collective register bank save for rapid context switching - all critical for deterministic motor control loop execution in the R5F526TFBGND#30.

Does the R5F526TFBGND#30 support IEC60730 Class B compliance out of the box?

Yes, the R5F526TFBGND#30 integrates multiple hardware features required for IEC60730 Class B compliance, including oscillation-stop detection, RAM test assist (DOC), CRC calculator (CRCA), independent watchdog timer (IWDT) with window function, register write protection, and self-diagnostic A/D disconnection detection - enabling certified safety firmware implementation without external components in the R5F526TFBGND#30.

What package type and pin count does the R5F526TFBGND#30 use?

The R5F526TFBGND#30 uses the PLQP0100KB-B package: a 100-pin Low-Profile Quad Flat Package (LFQFP) with 14 × 14 mm body size, 0.5 mm pitch, and exposed thermal pad. This package provides 82 general-purpose I/O pins, two 5-V tolerant inputs, and dedicated pins for CAN FD, high-resolution PWM, and synchronized A/D triggering in the R5F526TFBGND#30.

How many A/D converter units does the R5F526TFBGND#30 include, and what is their sampling capability?

The R5F526TFBGND#30 includes three independent 12-bit S12ADH A/D converter units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels), all supporting simultaneous sampling triggered by a single event. Minimum conversion time is 0.9 µs per channel at 60 MHz ADCLK - enabling precise, skew-free current and voltage acquisition for FOC in the R5F526TFBGND#30.

What is the role of the Event Link Controller (ELC) in the R5F526TFBGND#30?

The Event Link Controller (ELC) in the R5F526TFBGND#30 enables hardware-level interconnection of 183 internal peripheral events - such as MTU3d overflow, GPTWa compare match, or IWDT timeout - to trigger actions like A/D conversion start, PWM output disable, or port state change without CPU intervention. This reduces interrupt latency and CPU load in real-time motor control tasks within the R5F526TFBGND#30.
