For engineers reviewing the R5F526TFCGNE#50 datasheet, R5F526TFCGNE#50 pinout, R5F526TFCGNE#50 application, or R5F526TFCGNE#50 equivalent, key selection criteria include its dual-bank flash architecture for safe firmware updates, IEC60730-compliant safety features (oscillation-stop detection, RAM test assist, CRC), and dedicated motor-control peripherals including GPTWa timers with dead-time control and MTU3d for synchronized 3-phase waveform output.

Technical Context

The R5F526TFCGNE#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-critical for real-time motor control loops. It integrates a dedicated event link controller (ELC) enabling interrupt-free inter-module triggering between timers, ADCs, and PWM units.

Its clock system supports independent domain scaling: PCLKA at up to 120 MHz for GPTWa/MTU3d/HRPWM, PCLKC at 120 MHz for counter reference clocks, and PCLKD at 60 MHz for S12ADH ADC operation. The device uses a PLQP0100KB-B 100-pin LQFP package (14 × 14 mm, 0.5 mm pitch) with 82 general-purpose I/O pins, 2 of which are 5-V tolerant.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TFCGNE#50?

The R5F526TFCGNE#50 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance stems from its RXv3 CPU core with single-cycle instruction execution, on-chip 32-bit multiplier/divider, and barrel shifter-enabling deterministic real-time response for motor control algorithms. The R5F526TFCGNE#50 sustains full 120 MHz operation across all memory and peripheral interfaces without wait states.

Does the R5F526TFCGNE#50 support IEC60730 Class B compliance out of the box?

Yes, the R5F526TFCGNE#50 includes hardware features required for IEC60730 Class B certification: oscillation-stop detection, independent watchdog timer (IWDT) with window function, RAM test assist via DOC, CRC calculator (CRCA), register write protection, and self-diagnostic ADC functions. These are documented in Renesas Application Note R01AN3819JJ0100 and validated in the RX26T Safety Manual-no external components are needed to meet core diagnostic coverage requirements.

What PWM resolution and complementary output capability does the R5F526TFCGNE#50 provide?

The R5F526TFCGNE#50 delivers 260 ps minimum timing resolution via its 4-channel HRPWM circuit synchronized with GPTWa timers, enabling precise dead-time control for 3-phase inverter bridges. It supports 10 single-phase, 3 three-phase, and 2 five-phase complementary PWM outputs with automatic dead-time insertion, non-overlap enforcement, and short-circuit fault shutdown via POE3D-fully meeting JEDEC JESD22-A114 reliability requirements for motor gate drivers.

Which package and temperature grade does the R5F526TFCGNE#50 use?

The R5F526TFCGNE#50 uses the PLQP0100KB-B package: a 100-pin LQFP with 14 × 14 mm body, 0.5 mm pitch, and exposed thermal pad. It is rated for the G-version industrial temperature range of –40°C to +105°C, qualified per AEC-Q100 Grade 2 for extended thermal reliability in motor drive enclosures and outdoor power electronics environments.

How many ADC channels and what sampling capability does the R5F526TFCGNE#50 offer?

The R5F526TFCGNE#50 integrates a 12-bit S12ADH ADC with 21 total input channels distributed across three units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels). It supports simultaneous sampling across all three units, 0.9 µs minimum conversion time at 60 MHz ADCLK, and hardware-triggered acquisition synchronized to PWM edges via ELC-enabling accurate current/voltage measurement in high-frequency inverter topologies.
