Product details
Overview
R5F526T9ADFP#10 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 complementary PWM with dead-time control - deployed in HVAC compressors, servo drives, and industrial PMSM/BLDC motor systems.
For engineers reviewing the R5F526T9ADFP#10 datasheet, R5F526T9ADFP#10 pinout, R5F526T9ADFP#10 application, or R5F526T9ADFP#10 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, RAM test assist), and dual-bank flash enabling safe firmware updates during operation.
Technical Context
The R5F526T9ADFP#10 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 with external 8–24 MHz crystal support, internal HOCO (16/18/20 MHz), and dedicated 120 kHz IWDT oscillator.
Peripheral coordination is managed via the Event Link Controller (ELC), enabling 183 internal event signals to trigger timer starts/stops, A/D conversions, or port output changes without CPU intervention - critical for deterministic timing in field-oriented control (FOC) and sensorless commutation algorithms.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526T9ADFP#10?
The R5F526T9ADFP#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance level enables deterministic execution of complex motor control algorithms such as field-oriented control (FOC) and sensorless commutation within tight timing constraints. The RXv3 CPU core's single-cycle instruction execution and integrated FPU further accelerate mathematical operations required by R5F526T9ADFP#10-based drive systems.
Does the R5F526T9ADFP#10 support IEC60730 Class B compliance out of the box?
Yes, the R5F526T9ADFP#10 includes multiple hardware features required for IEC60730 Class B certification: independent watchdog timer (IWDT) with dedicated 120 kHz oscillator, oscillation-stop detection, RAM test assist via DOC, CRC calculator (CRCA), and register write protection. These capabilities reduce external component count and simplify safety validation - making R5F526T9ADFP#10 suitable for certified industrial motor control applications without requiring additional safety monitors.
What PWM configurations does the R5F526T9ADFP#10 support for 3-phase inverter control?
The R5F526T9ADFP#10 supports three complementary PWM modes essential for 3-phase inverter control: 10-channel single-phase, 3-channel three-phase, and 2-channel five-phase complementary outputs via its GPTWa module. It also includes MTU3d with automatic dead-time insertion and non-overlapping waveform generation. Combined with HRPWM offering 260 ps timing resolution, R5F526T9ADFP#10 delivers precise gate-drive control for SiC and GaN-based inverters used in high-efficiency motor drives.
How many analog-to-digital converter channels does the R5F526T9ADFP#10 provide, and what is their sampling capability?
The R5F526T9ADFP#10 integrates the S12ADH 12-bit ADC with 22 total channels across three independent units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels). Each unit includes dedicated sample-and-hold circuits, enabling true simultaneous sampling - critical for accurate current reconstruction in 3-phase motor control. Minimum conversion time is 0.9 µs per channel when ADCLK runs at 60 MHz, and conversion can be triggered by software, timers, or ELC events.
What package type and pin count does the R5F526T9ADFP#10 use, and is it pin-compatible with other RX26T variants?
The R5F526T9ADFP#10 uses the PLQP0100KB-B package: a 100-pin LQFP measuring 14 × 14 mm with 0.5 mm pitch. It is not pin-compatible with smaller RX26T variants (e.g., 64-pin or 48-pin packages) due to differing pin counts and signal allocations. However, it shares the same RX26T architecture, peripheral register map, and software ecosystem - allowing firmware reuse across the family when migrating between package sizes.
