Product details
Overview
R5F526TBCDFP#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, 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), a temperature sensor (±1.0°C), and dual-bank flash for safe firmware updates.
For engineers reviewing the R5F526TBCDFP#30 datasheet, R5F526TBCDFP#30 pinout, R5F526TBCDFP#30 application, or R5F526TBCDFP#30 equivalent, key selection criteria include its 120 MHz GPTWa timer with 3-phase/5-phase complementary PWM, simultaneous sampling across three 12-bit A/D units (up to 7 channels), 6-channel analog comparator, and support for 5 V-tolerant I/O in a 100-pin LFQFP package.
Technical Context
The R5F526TBCDFP#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 an 8–24 MHz external crystal oscillator, internal HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator - all supporting PLL multiplication up to 120 MHz system clock (ICLK).
Peripheral synchronization is segmented: PCLKA (up to 120 MHz) drives MTU3d, GPTWa, HRPWM, RSPI, and CAN FD; PCLKC (up to 120 MHz) serves as counter reference for timers and HRPWM; PCLKD (up to 60 MHz) clocks the S12ADH A/D converter. The ELC enables 183 internal event signals to trigger module operations without CPU intervention - critical for deterministic motor control timing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F526TADFP#30 | Same RX26T family, identical 100-pin LFQFP package and 512 KB flash, but with 48 KB SRAM (vs. 64 KB) and reduced A/D units (two 12-bit units vs. three) | Limited to applications needing ≤2 simultaneous A/D sampling units and <64 KB real-time control buffer memory | Select when cost sensitivity outweighs need for full simultaneous 3-unit A/D sampling and larger SRAM for complex FOC or observer algorithms |
| R5F523T7DDFP#30 | RX23T family, 100-pin LFQFP, 256 KB flash, 32 KB SRAM, 12-bit A/D (2 units), no HRPWM, no I3C, lower CoreMark (525 @ 40 MHz) | Targeted at entry-level inverters with simpler control and lower switching frequencies (<10 kHz) | Choose for legacy-compatible designs where 120 MHz timing resolution and triple A/D unit concurrency are not required |
Compared with R5F526TBCDFP#30, the R5F526TADFP#30 offers identical package and flash but trades 16 KB SRAM and one A/D unit for lower cost, while the R5F523T7DDFP#30 delivers reduced performance and feature set at lower price - making both viable alternatives only when specific high-end capabilities (HRPWM, triple A/D, I3C, 64 KB SRAM) are unused in the target design.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526TBCDFP#30?
The R5F526TBCDFP#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark points under benchmark conditions. This performance stems from its RXv3 CPU core with single-cycle instruction execution, on-chip FPU, and efficient memory subsystem - enabling real-time execution of complex motor control algorithms such as field-oriented control (FOC) and model predictive control (MPC) without external acceleration.
Does the R5F526TBCDFP#30 support CAN FD, and what standard does it comply with?
Yes, the R5F526TBCDFP#30 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard (11-bit) and extended (29-bit) frame formats. It enables data rates up to 5 Mbps in the data phase, making it suitable for high-bandwidth automotive and industrial network applications where traditional CAN 2.0B is insufficient for firmware updates or diagnostic streaming.
How many A/D converter units does the R5F526TBCDFP#30 have, and what is their sampling capability?
The R5F526TBCDFP#30 includes three independent 12-bit A/D converter units (S12ADH): 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 three units - critical for capturing synchronized current, voltage, and temperature measurements in 3-phase motor control applications.
What is the resolution and timing capability of the HRPWM in the R5F526TBCDFP#30?
The HRPWM in the R5F526TBCDFP#30 provides a minimum timing resolution of 260 ps when operating at 120 MHz. It enhances the GPTWa timer outputs (GPTW0–GPTW3) to enable ultra-fine dead-time adjustment and asymmetric PWM edge placement - essential for minimizing shoot-through risk and optimizing efficiency in SiC and GaN-based inverter designs.
Is the R5F526TBCDFP#30 qualified for IEC60730 Class B safety compliance?
Yes, the R5F526TBCDFP#30 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stop detection, A/D converter self-diagnosis and disconnection detection, clock frequency accuracy measurement, independent watchdog timer (IWDTa), RAM test assist (DOC), CRC calculator (CRCA), and register write protection.
