For engineers reviewing the R5F526TFADFP#30 datasheet, R5F526TFADFP#30 pinout, R5F526TFADFP#30 application, or R5F526TFADFP#30 equivalent, key selection criteria include its 100-pin LFQFP package, 3-phase/5-phase complementary PWM capability, simultaneous sampling across three 12-bit ADC units, and support for real-time event-driven operation via ELC - critical for closed-loop motor control and power conversion systems.

Technical Context

The R5F526TFADFP#30 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 loops. Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator, enabling precise timing synchronization across PCLKA (120 MHz), PCLKC (120 MHz for timer reference), and PCLKD (60 MHz for ADC).

Peripheral integration centers on deterministic real-time control: GPTWa (32-bit × 8 channels) and MTU3d (16-bit × 9 channels) deliver synchronized PWM generation with dead-time compensation and phase-counting; HRPWM extends GPTW0–GPTW3 timing resolution to 260 ps; S12ADH provides up to 22-channel 12-bit ADC with three independent sample-and-hold units for simultaneous current/voltage sensing in 3-phase inverters.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TFADFP#30?

The R5F526TFADFP#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance level is sustained across its full temperature range (–40°C to +85°C) and enables real-time execution of complex motor control algorithms such as field-oriented control (FOC) and model predictive control (MPC) without external acceleration. The R5F526TFADFP#30 delivers deterministic timing for critical PWM and ADC operations at this clock rate.

Does the R5F526TFADFP#30 support IEC60730 Class B compliance out of the box?

Yes, the R5F526TFADFP#30 includes hardware features required for IEC60730 Class B certification: oscillation-stop detection, ADC disconnection check, RAM test assist via DOC, CRC calculator (CRCA), register write protection, and independent watchdog timer (IWDTa) with window function. These capabilities are implemented in silicon and documented in the R01DS0407EJ0120 datasheet. The R5F526TFADFP#30 does not require external components to meet core self-test requirements.

What PWM resolution does the R5F526TFADFP#30 achieve, and which timers support it?

The R5F526TFADFP#30 achieves a minimum PWM timing resolution of 260 ps using its High-Resolution PWM (HRPWM) circuit, which enhances the timing control of GPTW0 through GPTW3 outputs. This resolution is realized at 120 MHz system clock and applies specifically to those four GPTWa channels - not to MTU3d or other timers. The R5F526TFADFP#30 uses HRPWM to minimize dead-time uncertainty in SiC/GaN inverter designs.

How many ADC channels and sample-and-hold units does the R5F526TFADFP#30 provide?

The R5F526TFADFP#30 includes three 12-bit ADC units (S12ADH): Unit 0 (4 channels with 3 dedicated sample-and-hold circuits), Unit 1 (4 channels with 3 dedicated sample-and-hold circuits), and Unit 2 (14 channels). This configuration enables true simultaneous sampling across up to 6 analog inputs - essential for capturing synchronized current and voltage waveforms in 3-phase motor control. The R5F526TFADFP#30 supports <0.9 µs conversion time per channel when ADCLK runs at 60 MHz.

What package type and pin count does the R5F526TFADFP#30 use?

The R5F526TFADFP#30 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 industrial temperature range (–40°C to +85°C) and provides 82 general-purpose I/O pins, including 5-V tolerant inputs and large-current output drivers. This package matches the full-featured variant of the RX26T Group and is compatible with standard LFQFP reflow profiles.
