Overview
R5F526TACGFL#50 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 flash memory, 64 KB SRAM, 16 KB data flash, integrated CAN FD interface, and hardware-accelerated 3-phase/5-phase complementary PWM with 260 ps timing resolution.
For engineers reviewing the R5F526TACGFL#50 datasheet, R5F526TACGFL#50 pinout, R5F526TACGFL#50 application, or R5F526TACGFL#50 equivalent, key selection considerations include its dual-bank flash architecture enabling background programming, IEC60730-compliant safety features (oscillation-stop detection, RAM test assist, CRC calculator), and dedicated high-resolution PWM engine for precise gate timing in BLDC/PMSM inverters.
Technical Context
The R5F526TACGFL#50 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. It integrates a dedicated HRPWM module synchronized to GPTWa timers, achieving 260 ps minimum pulse-edge resolution at 120 MHz system clock.
Its clock system combines an 8–24 MHz external crystal oscillator with PLL synthesis, internal HOCO/LOCO oscillators, and independent IWDT-dedicated 120 kHz oscillator. Peripheral clocks are independently configurable: PCLKA up to 120 MHz for MTU3d/GPTWa/HRPWM, PCLKB up to 60 MHz for most peripherals, and PCLKD up to 60 MHz for A/D conversion.

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F526TADGFL#50 | Same RX26T family, identical 100-pin LFQFP package and 512 KB flash, but rated for –40°C to +85°C (D-version) instead of +105°C | Suitable for non-automotive industrial enclosures with lower ambient thermal stress | Select when extended temperature range is not required and cost optimization is prioritized |
| R5F523T5ADFP#30 | RX23T family, 100-pin LFQFP, 256 KB flash, 32 KB SRAM, no HRPWM, lower CoreMark (520 @ 40 MHz), lacks I3C and RI3C | Targeted at cost-sensitive, lower-performance motor control where 260 ps PWM resolution is unnecessary | Choose for simpler inverter designs with basic 3-phase PWM and reduced peripheral requirements |
Compared with R5F526TACGFL#50, the R5F526TADGFL#50 offers identical functionality at a lower temperature grade, while the R5F523T5ADFP#30 reduces flash/SRAM capacity and omits HRPWM/I3C to meet budget constraints-making the R5F526TACGFL#50 optimal for thermally demanding, high-precision motor control requiring safety certification and future-proof interfaces.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526TACGFL#50?
The R5F526TACGFL#50 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This benchmark reflects its RXv3 CPU core's efficient instruction pipeline, single-cycle execution capability, and integrated FPU-enabling real-time motor control loop execution within strict timing budgets. The R5F526TACGFL#50 sustains this performance across its full operating temperature range (–40°C to +105°C).
Does the R5F526TACGFL#50 support IEC60730 functional safety compliance?
Yes, the R5F526TACGFL#50 includes multiple hardware features supporting Class B IEC60730 compliance: oscillation-stop detection for main clock failure, self-diagnostic ADC with disconnection monitoring, CRC calculator (CRCA) for memory/data integrity, RAM test assist via DOC, and register write protection. These are documented in the R01DS0407EJ0120 datasheet and validated per Renesas' safety manual for the RX26T Group.
What PWM resolution does the R5F526TACGFL#50 achieve, and how is it implemented?
The R5F526TACGFL#50 achieves a minimum PWM edge resolution of 260 ps using its dedicated HRPWM module synchronized to the 32-bit GPTWa timers running at 120 MHz. This is realized through fine-grained counter clock division and digital delay adjustment-enabling precise dead-time control critical for minimizing shoot-through in 3-phase inverter bridges. The R5F526TACGFL#50 delivers this resolution across all four HRPWM channels.
Which communication interfaces are included in the R5F526TACGFL#50, and what are their key capabilities?
The R5F526TACGFL#50 integrates CAN FD (ISO11898-1:2015, up to 5 Mbps), 4× SCI, 3× RSCI (with Manchester encoding and HBS), 1× I²C (RIICa, 400 kbps), 1× I3C (RI3C, SDR mode), and 2× RSPI (RSPId/RSPIA, up to 30 Mbps). Its ELC allows event-triggered transfers-e.g., timer overflow initiating ADC sampling-eliminating software overhead and ensuring deterministic timing in motor control loops.
What is the flash and SRAM configuration of the R5F526TACGFL#50, and how does it support firmware updates?
The R5F526TACGFL#50 features 512 KB of on-chip code flash memory organized in a dual-bank structure and 64 KB of no-wait SRAM. The dual-bank architecture enables background programming (BGO): firmware updates can be written to one bank while the application executes from the other-ensuring zero downtime during field upgrades. This capability is natively supported by Renesas' Flash Development Toolkit and documented in the R5F526TACGFL#50's flash programming specifications.
