For engineers reviewing the R5F526TFDDNE#50 datasheet, R5F526TFDDNE#50 pinout, R5F526TFDDNE#50 application, or R5F526TFDDNE#50 equivalent, key selection criteria include its 120 MHz PWM timing resolution (260 ps minimum), triple 12-bit A/D converter units supporting simultaneous sampling, 6-channel analog comparator, and Trusted Secure IP Lite encryption with AES-128/256 for IEC 60730-compliant safety-critical firmware.

Technical Context

The R5F526TFDDNE#50 implements the RXv3 CPU core with collective register bank save, memory protection unit (MPU), and single-precision FPU conforming to IEEE 754. It supports three low-power modes and operates from a single 2.7–5.5 V supply.

Its real-time peripheral architecture includes event-linking controller (ELC) enabling interrupt-free inter-module coordination, GPTWa timers with 3-phase/5-phase complementary PWM generation, and HRPWM circuit synchronized to GPTW0–GPTW3 for sub-nanosecond edge placement - all clocked at up to 120 MHz on PCLKA/PCLKC domains.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TFDDNE#50?

The R5F526TFDDNE#50 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance under benchmark conditions. This reflects the efficiency of its RXv3 CPU core with optimized instruction pipeline and on-chip memory subsystem - enabling real-time execution of complex motor control algorithms such as field-oriented control (FOC) without latency bottlenecks. The R5F526TFDDNE#50 sustains this performance across its full temperature range (–40°C to +85°C).

Does the R5F526TFDDNE#50 support CAN FD, and what standard does it comply with?

Yes, the R5F526TFDDNE#50 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames with data rates up to 5 Mbps in FD mode. It includes dedicated TX/RX pins (CANFD_TX/CANFD_RX), built-in bit-rate switching, and error confinement logic - making the R5F526TFDDNE#50 suitable for high-bandwidth diagnostics and firmware updates in industrial networks where legacy CAN 2.0B is insufficient.

How many A/D converter channels does the R5F526TFDDNE#50 support, and what is their sampling capability?

The R5F526TFDDNE#50 supports 22 total A/D input channels distributed across three independent 12-bit S12ADH units (4+4+14), enabling true simultaneous sampling with matched sample-and-hold timing. Minimum conversion time is 0.9 µs per channel at 60 MHz ADCLK, and the R5F526TFDDNE#50 allows group-priority scanning and digital comparison against programmable thresholds - essential for fast current-loop closure in servo drives.

What PWM resolution and complementary output capabilities does the R5F526TFDDNE#50 provide?

The R5F526TFDDNE#50 delivers 32-bit GPTWa timers with 8 channels and 4-channel HRPWM achieving a minimum timing resolution of 260 ps at 120 MHz - enabling nanosecond-accurate dead-time insertion and phase-edge calibration. It supports single-phase (10 outputs), 3-phase (3 outputs), and 5-phase (2 outputs) complementary PWM modes with automatic dead-time generation and synchronous counter clearing - all coordinated via the R5F526TFDDNE#50's ELC for CPU-free operation.

Is the R5F526TFDDNE#50 qualified for IEC 60730 safety compliance, and what features enable this?

Yes, the R5F526TFDDNE#50 includes multiple hardware features certified for IEC 60730 Class B compliance: oscillation-stop detection, RAM test assist (DOC), CRC calculator (CRCA), self-diagnostic A/D disconnection check, independent watchdog timer (IWDTa) with window function, and register write protection. These are implemented in silicon - not software libraries - ensuring deterministic behavior. The R5F526TFDDNE#50's Trusted Secure IP Lite further supports secure boot and firmware authentication required for end-product certification.
