Product details
Overview
R5F526TBAGFM#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 PWM generation with dead-time control - deployed in HVAC compressors, servo drives, and industrial PMSM/BLDC motor systems.
For engineers reviewing the R5F526TBAGFM#30 datasheet, R5F526TBAGFM#30 pinout, R5F526TBAGFM#30 application, or R5F526TBAGFM#30 equivalent, key selection criteria include its 120 MHz GPTWa timer with 10-channel single-phase complementary PWM, 260 ps HRPWM timing resolution, IEC60730-compliant safety features (IWDT, oscillation-stop detection, CRC, RAM test assist), and dual-bank flash enabling safe firmware updates during operation.
Technical Context
The R5F526TBAGFM#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 integrates PLL-driven 120 MHz ICLK, independent IWDT oscillator (120 kHz), and configurable peripheral clocks (PCLKA up to 120 MHz, PCLKB/C/D at derived frequencies) to synchronize high-speed timers and analog peripherals.
Motor control execution relies on tightly coupled peripherals: MTU3d (9-channel 16-bit timer) and GPTWa (8-channel 32-bit timer) operate on PCLKC for precise PWM edge placement; HRPWM overlays sub-260 ps timing adjustments onto GPTW outputs; S12ADH A/D converter supports simultaneous sampling across three units (4+4+14 channels) with programmable gain amplifiers and digital comparison for overcurrent detection.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526TBAGFM#30?
The R5F526TBAGFM#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark points under benchmark conditions. This performance stems from the RXv3 CPU core's single-cycle instruction execution, 32-bit multiplier/divider, and barrel shifter - enabling deterministic loop execution essential for real-time motor control algorithms. The R5F526TBAGFM#30 maintains this speed across its full 2.7–5.5 V supply range with no wait states on code flash or SRAM access.
Does the R5F526TBAGFM#30 support IEC60730 Class B compliance out of the box?
Yes, the R5F526TBAGFM#30 includes multiple hardware features required for IEC60730 Class B compliance: independent watchdog timer (IWDT) with windowing, main clock oscillation-stop detection, CRC calculator (CRCA), RAM test assist via DOC, analog comparator disconnection detection, and register write protection. These are documented in the R01DS0407EJ0120 datasheet and enable certified self-test routines without external components - reducing validation effort for R5F526TBAGFM#30-based designs.
What PWM configurations does the R5F526TBAGFM#30 support for 3-phase motor control?
The R5F526TBAGFM#30 supports three complementary PWM modes for 3-phase motor control: 10-channel single-phase, 3-channel 3-phase, and 2-channel 5-phase - all implemented via GPTWa and MTU3d timers. It delivers non-overlapping waveforms with hardware-managed dead-time insertion, automatic fault shutdown via POE3D, and HRPWM overlay for sub-260 ps edge timing adjustment. These capabilities are validated for use in PMSM and BLDC inverter topologies per the RX26T Group reference designs.
How many A/D converter channels does the R5F526TBAGFM#30 provide, and what sampling capability does it offer?
The R5F526TBAGFM#30 includes the S12ADH 12-bit A/D converter with three independent sample-and-hold units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels), totaling 22 configurable inputs. It supports simultaneous sampling across all units, 0.9 µs minimum conversion time at 60 MHz ADCLK, and programmable gain amplifiers on Units 0 and 1 - enabling precise, synchronized current and voltage sensing for vector control in motor drive applications using the R5F526TBAGFM#30.
