Product details
Overview
R5F526TBAGFP#50 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, operating at up to 120 MHz with 709 CoreMark performance, integrated 512 KB code flash, 64 KB SRAM, 16 KB data flash, and hardware-accelerated 3-phase/5-phase complementary PWM generation. It integrates CAN FD, dual 12-bit A/D converters (22-channel total), 6-channel analog comparators, 2-channel 12-bit D/A, HRPWM with 260 ps timing resolution, and Trusted Secure IP Lite encryption.
For engineers reviewing the R5F526TBAGFP#50 datasheet, R5F526TBAGFP#50 pinout, R5F526TBAGFP#50 application, or R5F526TBAGFP#50 equivalent, key selection considerations include its 100-pin LFQFP package, 120 MHz real-time PWM timing capability, IEC60730 safety support, dual-bank flash for safe firmware updates, and dedicated motor control peripherals including MTU3d, GPTWa, and POE3D.
Technical Context
The R5F526TBAGFP#50 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and 16-register bank save for fast context switching in motor control interrupt service routines. Its clock system supports PLL-synthesized 120 MHz ICLK, independent PCLKA/PCLKC domains enabling concurrent high-speed peripheral operation (e.g., GPTWa at 120 MHz, S12ADH at 60 MHz ADCLK).
It features tightly coupled motor control subsystems: MTU3d provides 3-phase complementary PWM with automatic dead-time insertion and phase-counting mode; GPTWa delivers 8-channel 32-bit PWM with synchronous start/stop and ELC-triggered A/D conversion; HRPWM refines GPTW0–GPTW3 outputs to 260 ps resolution for precise gate timing in SiC/GaN inverters.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526TBAGFP#50?
The R5F526TBAGFP#50 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This benchmark reflects its real-time capability for complex motor control algorithms such as field-oriented control (FOC) and model predictive control (MPC), validated under actual 120 MHz operation with no wait states. The RXv3 core's single-cycle instruction execution and collective register bank save further enhance deterministic interrupt response in the R5F526TBAGFP#50.
Does the R5F526TBAGFP#50 support IEC60730 Class B compliance out of the box?
Yes, the R5F526TBAGFP#50 includes hardware features required for IEC60730 Class B compliance: oscillation-stop detection, RAM test assist (DOC), CRC calculator (CRCA), A/D converter disconnection detection, independent watchdog timer (IWDTa) with window function, and register write protection. These are documented in the R01DS0407EJ0120 datasheet and enable certified self-test routines without external components - a key design advantage of the R5F526TBAGFP#50.
What PWM resolution does the R5F526TBAGFP#50 achieve, and how is it implemented?
The R5F526TBAGFP#50 achieves a minimum PWM timing resolution of 260 ps using its High-Resolution PWM (HRPWM) circuit, which refines outputs from GPTW0–GPTW3 channels. This is realized by injecting fine delay adjustments into the 120 MHz GPTW counter path, enabling sub-nanosecond edge placement critical for SiC/GaN gate drivers. The R5F526TBAGFP#50 datasheet confirms this value applies specifically to the 100-pin G-version devices like R5F526TBAGFP#50.
How many A/D converter channels does the R5F526TBAGFP#50 support, and what is their architecture?
The R5F526TBAGFP#50 supports 22 total 12-bit A/D converter channels across three units: S12ADH Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels). Each of Units 0 and 1 includes three dedicated sample-and-hold circuits, enabling true simultaneous sampling across up to six channels - essential for accurate three-phase current reconstruction. This architecture is confirmed for the 64 KB RAM variant, which the R5F526TBAGFP#50 implements.
What is the package type and temperature grade of the R5F526TBAGFP#50?
The R5F526TBAGFP#50 uses the PLQP0100KB-B package: a 100-pin low-profile quad flat package (LFQFP) with 14 × 14 mm body size and 0.5 mm pin pitch. It is rated for the G-version operating temperature range of –40°C to +105°C, making it suitable for under-hood automotive auxiliary systems and industrial environments with elevated ambient temperatures - a defined specification for the R5F526TBAGFP#50 in the official Renesas documentation.
