It operates across –40°C to +85°C and supports IEC60730 functional safety compliance.

For engineers reviewing the R5F526TBBDFP#10 datasheet, R5F526TBBDFP#10 pinout, R5F526TBBDFP#10 application, or R5F526TBBDFP#10 equivalent, key selection criteria include real-time PWM timing precision (260 ps), dual-bank flash for safe firmware updates, on-chip Trusted Secure IP Lite encryption, simultaneous sampling across three 12-bit A/D units, and event-driven peripheral coordination via ELC-critical for deterministic motor control loop execution.

Technical Context

The R5F526TBBDFP#10 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 in interrupt-heavy motor control tasks. Its clock system integrates PLL-synthesized 120 MHz ICLK, independent PCLKA/PCLKC domains for peripheral timing isolation, and dedicated IWDT oscillator for fail-safe watchdog operation.

Peripheral architecture centers on deterministic timing: GPTWa (32-bit × 8 channels) and MTU3d (16-bit × 9 channels) provide synchronized PWM output with dead-time compensation, while ELC enables direct inter-module triggering without CPU intervention-enabling sub-microsecond response between analog capture, PWM update, and fault shutdown events.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TBBDFP#10?

The R5F526TBBDFP#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance level enables real-time execution of complex field-oriented control (FOC) algorithms, fast Fourier transforms for vibration analysis, and multi-axis motion profiling-all within a single R5F526TBBDFP#10 device.

Does the R5F526TBBDFP#10 support IEC60730 Class B compliance out of the box?

Yes, the R5F526TBBDFP#10 includes dedicated hardware features required for IEC60730 Class B certification: oscillation-stop detection, RAM test assist via DOC, CRC calculator (CRCA), register write protection, independent watchdog timer with window function, and self-diagnostic A/D converter functions. These capabilities reduce external component count and simplify certification documentation for the R5F526TBBDFP#10.

What PWM configurations does the R5F526TBBDFP#10 support for 3-phase inverter control?

The R5F526TBBDFP#10 supports 3-phase complementary PWM using both MTU3d (9 channels) and GPTWa (8 channels), with automatic dead-time insertion, non-overlapping waveform generation, and synchronous update across all phases. It also provides 5-phase complementary mode (2 channels) and single-phase complementary mode (10 channels), all controllable via hardware ELC triggers for deterministic timing in the R5F526TBBDFP#10.

How many analog input channels can be sampled simultaneously on the R5F526TBBDFP#10?

The R5F526TBBDFP#10 supports simultaneous sampling across three independent 12-bit A/D units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels), totaling up to 22 channels. This capability is enabled by dedicated sample-and-hold circuits per unit and hardware synchronization via MTU/GPTW triggers-ensuring phase-aligned current and voltage measurements critical for the R5F526TBBDFP#10's motor control applications.

What package type and pin count does the R5F526TBBDFP#10 use?

The R5F526TBBDFP#10 uses the PLQP0100KB-B package: a 100-pin Low-Profile Quad Flat Package (LFQFP) with 14 × 14 mm body size, 0.5 mm pitch, and exposed thermal pad. This industrial-grade package provides robust thermal performance and 5-V tolerant I/O-ideal for high-noise motor drive environments where the R5F526TBBDFP#10 is deployed.
