For engineers reviewing the R5F526TBCGFP#10 datasheet, R5F526TBCGFP#10 pinout, R5F526TBCGFP#10 application, or R5F526TBCGFP#10 equivalent, key selection criteria include its 100-pin LFQFP package, dual-bank flash for safe firmware updates, simultaneous sampling across three 12-bit A/D units, 3-phase/5-phase complementary PWM generation, and hardware-accelerated trigonometric functions (TFUv2) for real-time motor vector control.

Technical Context

The R5F526TBCGFP#10 implements the RXv3 CPU core with single-cycle instruction execution at 120 MHz, supporting IEEE 754-compliant single-precision FPU and 113 instructions including DSP extensions. Its memory subsystem integrates dual-bank 512 KB flash enabling background programming while executing from alternate bank, plus 64 KB zero-wait SRAM with SED error detection.

Peripheral architecture centers on deterministic real-time control: GPTWa timers deliver 32-bit PWM with synchronous start/stop across 8 channels; MTU3d provides 9-channel 16-bit timer resources with dead-time compensation and phase-counting mode; HRPWM achieves 260 ps edge placement resolution for precise gate drive timing in SiC/GaN inverter designs.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TBCGFP#10?

The R5F526TBCGFP#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency, including single-cycle instruction execution, 32-bit multiplier/divider, and barrel shifter - all critical for real-time motor control loop execution. The R5F526TBCGFP#10 maintains this performance across its full operating temperature range (–40°C to +105°C).

Does the R5F526TBCGFP#10 support simultaneous sampling across multiple A/D units?

Yes, the R5F526TBCGFP#10 supports simultaneous sampling using three independent 12-bit A/D units (S12ADH): two units with 4 channels each (including sample-and-hold) and one unit with 14 channels. This capability enables synchronized acquisition of motor phase currents and DC-link voltage within a single PWM period - a requirement for high-fidelity field-oriented control. The R5F526TBCGFP#10 uses hardware triggers from GPTWa or MTU3d to initiate concurrent conversions.

What PWM resolution does the R5F526TBCGFP#10 provide, and how is it achieved?

The R5F526TBCGFP#10 delivers 260 ps minimum edge placement resolution via its 4-channel High-Resolution PWM (HRPWM) peripheral, which enhances the timing accuracy of GPTWa outputs. This resolution is achieved by interpolating between PCLKC cycles (up to 120 MHz) using dedicated HRPWM logic - enabling precise gate drive timing for SiC and GaN power devices. The R5F526TBCGFP#10 applies this resolution specifically to GPTW0 through GPTW3 outputs, not to MTU3d or other timers.

Which safety standards does the R5F526TBCGFP#10 support out of the box?

The R5F526TBCGFP#10 includes hardware features certified for IEC60730 Class B compliance: oscillation-stop detection, A/D disconnection monitoring, clock accuracy measurement, independent watchdog timer (IWDTa), RAM test assistance via DOC, CRC calculator (CRCA), and register write protection. These are implemented in silicon and require no external components. The R5F526TBCGFP#10 also supports optional Trusted Secure IP Lite for secure boot and firmware authentication, extending safety into the security domain.

What is the package type and pin count of the R5F526TBCGFP#10?

The R5F526TBCGFP#10 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 operation from –40°C to +105°C (G-version). This package provides 82 general-purpose I/O pins with 5-V tolerance, 15 high-current outputs, and dedicated signal routing for motor control peripherals - including separate power domains for analog and digital sections.
