Product details
Overview
R5F526T9ADND#30 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring a 120 MHz CPU core delivering 709 CoreMark, 512 KB on-chip code flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD interface, and hardware-accelerated 3-phase complementary PWM with dead-time control - deployed in HVAC compressors, servo drives, and industrial PMSM/BLDC motor systems.
For engineers reviewing the R5F526T9ADND#30 datasheet, R5F526T9ADND#30 pinout, R5F526T9ADND#30 application, or R5F526T9ADND#30 equivalent, key selection criteria include real-time PWM resolution (260 ps HRPWM), IEC60730 safety support (oscillation detection, RAM test assist, CRC, register write protection), dual-bank flash for safe firmware updates, and 83 GPIOs with 5-V tolerance and configurable drive strength.
Technical Context
The R5F526T9ADND#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16-register bank save for fast context switching in motor control interrupt routines. Its clock system integrates PLL with 8–24 MHz crystal input, 240 kHz LOCO, and 120 kHz IWDT-dedicated oscillator - enabling independent timing domains for CPU (ICLK up to 120 MHz), peripherals (PCLKA up to 120 MHz), and ADC (ADCLK up to 60 MHz).
Motor-specific peripherals include eight 32-bit GPTWa channels supporting 10-channel single-phase, 3-channel 3-phase, and 2-channel 5-phase complementary PWM; nine-channel MTU3d with automatic dead-time insertion and phase-counting; six-channel analog comparator; and simultaneous-sampling 12-bit S12ADH with three sample-and-hold units - all coordinated via Event Link Controller (ELC) to eliminate CPU intervention during waveform generation and A/D triggering.

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F526T7ADND#30 | Same RX26T family, 256 KB code flash, 48 KB SRAM, 49-pin I/O count, no HRPWM module | Targeted at cost-sensitive single-phase or low-power BLDC applications without 5-phase PWM or sub-ns timing needs | Select when flash/SRAM requirements are lower and HRPWM resolution is not required for gate driver timing. |
| R5F566TEADFP#30 | RX66T family, 160 MHz CPU, 1 MB flash, 256 KB SRAM, enhanced GPTW with 12-channel 3-phase PWM, no HRPWM | Designed for higher-performance servo drives requiring >100 kHz PWM carrier frequency and larger code footprint | Choose for next-generation designs needing higher clock speed, larger memory, and extended timer channel count - but without 260 ps edge control. |
Compared with R5F526T9ADND#30, R5F526T7ADND#30 reduces memory and removes HRPWM for cost-sensitive use cases, while R5F566TEADFP#30 increases performance and scale but lacks the ultra-fine PWM timing critical for SiC/GaN gate drivers - making R5F526T9ADND#30 optimal for precision inverter control where nanosecond-level dead-time accuracy is mandatory.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526T9ADND#30?
The R5F526T9ADND#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 - enabling deterministic real-time response in motor control loops. The R5F526T9ADND#30 sustains this speed across its 512 KB flash and 64 KB SRAM with zero wait states.
Does the R5F526T9ADND#30 support IEC60730 functional safety certification?
Yes, the R5F526T9ADND#30 includes multiple hardware features required for IEC60730 Class B compliance: oscillation-stop detection for main clock, self-diagnostic A/D converter, RAM test assist via Data Operation Controller (DOC), CRC calculator (CRCA), register write protection, and independent watchdog timer (IWDTa) with window function. These capabilities are documented in the R01DS0407EJ0120 datasheet and enable certified safety firmware implementation - critical for R5F526T9ADND#30-based appliance and industrial drive designs.
What PWM configurations does the R5F526T9ADND#30 support for 3-phase inverter control?
The R5F526T9ADND#30 supports three complementary PWM modes essential for 3-phase inverter control: 3-channel 3-phase complementary PWM (via MTU3d), 10-channel single-phase complementary PWM, and 2-channel 5-phase complementary PWM (via GPTWa). It also provides hardware dead-time insertion, synchronous counter clearing, and HRPWM with 260 ps minimum edge resolution - allowing precise gate timing for SiC and GaN power stages. All configurations are accessible through the R5F526T9ADND#30's unified timer peripheral architecture.
How many analog-to-digital converter channels does the R5F526T9ADND#30 have, and what sampling capability is supported?
The R5F526T9ADND#30 integrates a 12-bit S12ADH A/D converter with 22 total input channels: 4+4+14 across three units. It supports simultaneous sampling using three independent sample-and-hold circuits (Unit 0: 3 channels, Unit 1: 3 channels, Unit 2: 14 channels), enabling synchronized current/voltage acquisition across motor phases. Minimum conversion time is 0.9 µs per channel at 60 MHz ADCLK - a capability confirmed in the R5F526T9ADND#30 datasheet and critical for high-bandwidth motor control.
What package type and pin count does the R5F526T9ADND#30 use?
The R5F526T9ADND#30 uses the PLQP0100KB-B package: a 100-pin Low-Profile Quad Flat Package with 14 mm × 14 mm body size, 0.5 mm lead pitch, and exposed thermal pad. This package supports 83 general-purpose I/O pins with 5-V tolerance, open-drain capability, and configurable drive strength - validated in Renesas' official packaging documentation for the RX26T Group and directly applicable to the R5F526T9ADND#30 variant.
