Product details
Overview
R5F526T9ADFM#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 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 safe firmware updates.
For engineers reviewing the R5F526T9ADFM#30 datasheet, R5F526T9ADFM#30 pinout, R5F526T9ADFM#30 application, or R5F526T9ADFM#30 equivalent, key selection considerations include its 100-pin LFQFP package, 3-phase/5-phase complementary PWM capability, simultaneous sampling across three 12-bit A/D units, and support for real-time event linking via ELC - critical for deterministic motor control timing.
Technical Context
The R5F526T9ADFM#30 implements the RXv3 CPU core with single-cycle instruction execution at 120 MHz, delivering 709 CoreMark performance and supporting little-endian or big-endian data arrangement. Its memory subsystem includes dual-bank 512 KB flash enabling background programming and bank-swapping during operation, plus 64 KB zero-wait SRAM with SED error detection.
Motor control is enabled by tightly coupled peripherals: GPTWa (32-bit × 8 channels) and MTU3d (16-bit × 9 channels) provide synchronized PWM generation, dead-time insertion, and phase-counting; HRPWM adds 260 ps fine timing control to GPTW0–GPTW3 outputs; and S12ADH delivers simultaneous sampling across 23 analog inputs (Unit 0: 4 ch × 3 SH, Unit 1: 4 ch × 3 SH, Unit 2: 14 ch) with programmable gain amplifiers.

The R5F526T9ADFM#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This benchmark reflects its RXv3 CPU core's efficiency in executing real-time motor control algorithms, including field-oriented control (FOC) loops and trigonometric calculations via its integrated FPU. The R5F526T9ADFM#30 sustains this performance with zero-wait-state access to both 512 KB flash and 64 KB SRAM.
Does the R5F526T9ADFM#30 support IEC60730 Class B compliance out of the box?
Yes, the R5F526T9ADFM#30 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stop detection, RAM test assist (DOC), clock frequency accuracy measurement, independent watchdog timer (IWDTa), and register write protection. These are implemented in silicon and require no external components. When used with Renesas' certified safety libraries, the R5F526T9ADFM#30 enables certified motor control designs without adding safety co-processors.
What PWM capabilities does the R5F526T9ADFM#30 offer for 3-phase inverter control?
The R5F526T9ADFM#30 provides comprehensive PWM support for 3-phase inverters via MTU3d (9-channel 16-bit) and GPTWa (8-channel 32-bit), both synchronized to PCLKC at up to 120 MHz. It supports complementary PWM with automatic dead-time insertion, 3-phase/5-phase modes, and HRPWM with 260 ps resolution on GPTW0–GPTW3 outputs. The R5F526T9ADFM#30 also integrates POE3D for hardware-triggered output disable during overcurrent events.
How many analog input channels does the R5F526T9ADFM#30 support, and what is its sampling capability?
The R5F526T9ADFM#30 integrates three 12-bit S12ADH A/D converter units: Unit 0 (4 channels with 3 sample-and-hold circuits), Unit 1 (4 channels with 3 sample-and-hold circuits), and Unit 2 (14 channels). This enables simultaneous sampling across up to 23 analog inputs - essential for capturing phase currents, DC-link voltage, and temperature in a single cycle. Minimum conversion time is 0.9 µs per channel at 60 MHz ADCLK.
Is the R5F526T9ADFM#30 pin-compatible with other RX26T group MCUs?
Yes, the R5F526T9ADFM#30 is pin-compatible with other 100-pin RX26T variants such as R5F526TADFM#30 and R5F526TKDFM#30, sharing the PLQP0100KB-B LFQFP package and identical pin functions. This allows hardware reuse across designs with varying flash/SRAM configurations. However, it is not pin-compatible with 64-pin or 80-pin RX26T devices due to differing pin counts and signal allocations.
