For engineers reviewing the R5F526TBBGNE#50 datasheet, R5F526TBBGNE#50 pinout, R5F526TBBGNE#50 application, or R5F526TBBGNE#50 equivalent, key selection considerations include its 100-pin LQFP package with 82 general-purpose I/Os (2× 5-V tolerant), dual-bank flash for safe firmware updates, HRPWM with 260 ps timing resolution, and built-in safety features supporting IEC 60730 Class B compliance.

Technical Context

The R5F526TBBGNE#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. Its clock system integrates a PLL with 8–24 MHz external crystal support, internal HOCO/LOCO oscillators, and independent IWDT-dedicated 120 kHz oscillator.

Peripheral architecture centers on deterministic real-time control: GPTWa (32-bit × 8 channels) and MTU3d (16-bit × 9 channels) provide synchronized PWM, input capture, and phase-counting; ELC enables interrupt-free inter-module event chaining; and S12ADH supports simultaneous sampling across three 12-bit A/D units with programmable gain amplifiers.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TBBGNE#50?

The R5F526TBBGNE#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 in motor control loops. The R5F526TBBGNE#50 sustains this speed with no-wait access to both 512 KB flash and 64 KB SRAM.

Does the R5F526TBBGNE#50 support CAN FD, and what standard does it comply with?

Yes, the R5F526TBBGNE#50 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard (11-bit) and extended (29-bit) frame formats at data rates up to 5 Mbps. It includes dedicated TX/RX pins, message buffering, and error handling logic-making the R5F526TBBGNE#50 suitable for high-bandwidth industrial networked drives and automotive auxiliary systems.

What PWM resolution and channel count does the R5F526TBBGNE#50 offer for motor control?

The R5F526TBBGNE#50 delivers 10 single-phase, 3 three-phase, and 2 five-phase complementary PWM channels via its GPTWa and MTU3d timers, plus 4-channel High-Resolution PWM (HRPWM) with minimum timing resolution of 260 ps at 120 MHz. This enables precise dead-time insertion and phase alignment critical for minimizing electromagnetic interference and conduction losses in inverter designs using the R5F526TBBGNE#50.

How does the R5F526TBBGNE#50 support IEC 60730 Class B compliance?

The R5F526TBBGNE#50 includes multiple hardware features for IEC 60730 Class B certification: oscillation-stop detection, RAM test-assist via DOC, CRC calculator (CRCA), self-diagnostic A/D disconnection detection, register write protection, and independent watchdog timer with windowing. These functions are implemented in silicon-not software-ensuring deterministic behavior required for safety-critical appliance inverters using the R5F526TBBGNE#50.

What package type and thermal specifications apply to the R5F526TBBGNE#50?

The R5F526TBBGNE#50 uses the PLQP0100KB-B package: a 100-pin LQFP with 14 mm × 14 mm body, 0.5 mm pitch, and exposed thermal pad. It is rated for operation from –40°C to +105°C (G-version), with thermal resistance θJA ≈ 32°C/W. The package supports reflow soldering per J-STD-020 and is RoHS compliant-ensuring reliability in thermally demanding motor control environments where the R5F526TBBGNE#50 is deployed.
