Product details
Overview
R5F526TFDDND#10 from Renesas is a 32-bit RXv3 microcontroller designed for high-performance motor control and industrial inverter applications. It operates at up to 120 MHz, integrates 512 KB code flash, 64 KB SRAM, 16 KB data flash, dual-bank flash architecture, and supports CAN FD, 3-phase/5-phase complementary PWM, and 260-ps high-resolution PWM timing control.
For engineers reviewing the R5F526TFDDND#10 datasheet, R5F526TFDDND#10 pinout, R5F526TFDDND#10 application, or R5F526TFDDND#10 equivalent, key selection criteria include its 120-MHz real-time PWM capability with dead-time compensation, integrated analog front-end (12-bit ADC × 3 units, 6-channel comparator, 2-channel DAC), IEC60730 safety features, and Trusted Secure IP Lite encryption support.
Technical Context
The R5F526TFDDND#10 implements the RXv3 CPU core with single-precision FPU, 113 instructions, and collective register bank save-enabling fast context switching for deterministic motor control loops. Its clock system combines PLL-synthesized 120-MHz ICLK with independent PCLKA/PCLKC domains to drive GPTWa timers and HRPWM at full resolution while decoupling peripheral timing.
It integrates dedicated hardware acceleration for safety-critical functions: oscillation-stop detection, RAM test assistance via DOC, CRC calculation (CRCA), register write protection, and self-diagnostic A/D disconnection detection-all aligned with IEC60730 Class B compliance requirements for appliance and industrial drives.

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F526TADDFP#30 | Same RX26T Group, 64-pin HWQFN (7 × 7 mm), 256 KB flash, 48 KB SRAM, 48 I/O pins | Limited PWM channels (16-bit GPTWa), reduced ADC unit count (2 units), no HRPWM | Select for space-constrained cost-sensitive inverters where 3-phase PWM and basic safety suffice |

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526TFDDND#10?
The R5F526TFDDND#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance stems from its RXv3 CPU core with optimized pipeline, single-cycle instruction execution, and integrated 32-bit multiplier/divider-making it suitable for real-time motor control algorithms requiring deterministic timing and high computational throughput.
Does the R5F526TFDDND#10 support IEC60730 Class B compliance out of the box?
Yes, the R5F526TFDDND#10 includes built-in hardware features required for IEC60730 Class B compliance: oscillation-stop detection, RAM test assistance via DOC, CRC calculator (CRCA), register write protection, and self-diagnostic A/D disconnection detection. These are documented in Renesas Application Note R01AN4299JJ0100 and validated per the RX26T Functional Safety Manual.
What package type and pin count does the R5F526TFDDND#10 use?
The R5F526TFDDND#10 uses the PLQP0100KB-B package: a 100-pin Low-Profile Quad Flat Package measuring 14 mm × 14 mm with 0.5 mm pitch. It is rated for –40°C to +85°C operation (D-version) and includes an exposed thermal pad for enhanced heat dissipation in high-power motor control applications.
How many ADC units and channels does the R5F526TFDDND#10 support?
The R5F526TFDDND#10 supports three independent 12-bit S12ADH ADC units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels), totaling 22 configurable analog inputs. Each unit includes dedicated sample-and-hold circuits-enabling true simultaneous sampling across multiple current/voltage sensing paths in motor control systems.
What is the role of the Event Link Controller (ELC) in the R5F526TFDDND#10?
The Event Link Controller (ELC) in the R5F526TFDDND#10 enables hardware-level interconnection of 183 internal peripheral events-such as MTU overflow, GPTW compare match, or ADC completion-without CPU interrupt overhead. For example, an MTU3d timer overflow can directly trigger ADC conversion start and subsequent DMACA transfer, ensuring sub-microsecond deterministic response in real-time control loops.
