Product details
Overview
R5F526TFBDND#30 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring 120 MHz operation, 512 KB code flash, 64 KB SRAM, 16 KB data flash, CAN FD interface, and integrated high-resolution PWM with 260 ps timing resolution. It supports IEC60730 safety compliance and includes hardware encryption (AES-128/256), FPU, and dual-bank flash for seamless firmware updates.
For engineers reviewing the R5F526TFBDND#30 datasheet, R5F526TFBDND#30 pinout, R5F526TFBDND#30 application, or R5F526TFBDND#30 equivalent, key selection criteria include its 100-pin LFQFP package, 3-phase/5-phase complementary PWM capability, simultaneous sampling across three 12-bit A/D units, and dedicated HRPWM circuitry enabling sub-nanosecond dead-time control in motor drive designs.
Technical Context
The R5F526TFBDND#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. Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator, enabling precise timing for motor control loops and safety monitoring.
Peripheral architecture centers on event-driven operation via the Event Link Controller (ELC), which interconnects 183 internal signals-enabling timer-triggered ADC conversions, comparator-initiated PWM shutdown, and GPTW/MTU synchronization without CPU intervention-while maintaining low-latency response in sleep modes.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526TFBDND#30?
The R5F526TFBDND#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 efficient execution of motor control algorithms such as FOC and PID without external acceleration. The R5F526TFBDND#30 sustains this speed across its full memory map with no wait states.
Does the R5F526TFBDND#30 support IEC60730 Class B compliance out of the box?
Yes, the R5F526TFBDND#30 includes hardware features required for IEC60730 Class B compliance: oscillation-stop detection, A/D converter disconnection monitoring, clock accuracy measurement, independent watchdog timer (IWDTa), RAM test assist via DOC, and CRC calculator (CRCA). These are implemented in silicon-not software libraries-reducing certification effort. The R5F526TFBDND#30 also supports register write protection to prevent unintended configuration changes during runtime.
What PWM configurations does the R5F526TFBDND#30 support for 3-phase motor control?
The R5F526TFBDND#30 supports multiple 3-phase PWM modes: 10-channel single-phase complementary, 3-channel 3-phase complementary (via MTU3d), and 2-channel 5-phase complementary (via GPTWa). Its HRPWM circuit adds 260 ps edge resolution to GPTW0–GPTW3 outputs-enabling precise dead-time insertion critical for SiC/GaN inverter efficiency. All modes synchronize with ADC sampling via ELC-triggered ADTRG signals for deterministic current sensing.
How many A/D converter channels does the R5F526TFBDND#30 provide, and what is their sampling capability?
The R5F526TFBDND#30 includes three independent 12-bit S12ADH units totaling 22 channels: Unit 0 (4 channels, 3 sample-and-hold circuits), Unit 1 (4 channels, 3 sample-and-hold circuits), and Unit 2 (14 channels). It supports simultaneous sampling across all units with minimum conversion time of 0.9 µs per channel at 60 MHz ADCLK. This enables concurrent acquisition of three-phase currents and DC-link voltage without multiplexing delay-essential for accurate vector control.
What package type and pin count does the R5F526TFBDND#30 use, and is it RoHS compliant?
The R5F526TFBDND#30 uses a 100-pin Low-Profile Quad Flat Package (LFQFP) designated PLQP0100KB-B, measuring 14 × 14 mm with 0.5 mm pitch and an exposed thermal pad. It is RoHS compliant and rated for industrial temperature range (–40°C to +85°C). The package provides 82 general-purpose I/O pins, including two 5-V tolerant inputs and 15 large-current outputs-optimized for direct connection to gate drivers and sensors in motor control PCB layouts.
