FAQ
What is the maximum operating frequency and CoreMark score of the R5F526TBADFP#30?
The R5F526TBADFP#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This benchmark reflects its real-time computational capability for demanding motor control algorithms. The RXv3 core's single-cycle instruction execution and integrated FPU contribute directly to this score, and the value is measured under specified conditions in the official Renesas datasheet R01DS0407EJ0120. The R5F526TBADFP#30 maintains full performance across its rated temperature range of –40°C to +85°C.
Does the R5F526TBADFP#30 support simultaneous sampling across all A/D channels?
Yes, the R5F526TBADFP#30 supports simultaneous sampling using three independent 12-bit S12ADH units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels), totaling 22 channels. This capability is confirmed in the datasheet for devices with 64 KB SRAM, which the R5F526TBADFP#30 implements. Simultaneous sampling is triggered via hardware events (e.g., MTU3d overflow) and is essential for accurate current reconstruction in 3-phase motor control. The R5F526TBADFP#30 does not require software synchronization or channel multiplexing for this function.
What PWM resolution does the R5F526TBADFP#30 achieve with its HRPWM feature?
The R5F526TBADFP#30 achieves a minimum timing resolution of 260 ps using its High-Resolution PWM (HRPWM) circuit, which operates in conjunction with GPTW0–GPTW3 timers at 120 MHz. This specification is explicitly stated in the "Features" section of the R01DS0407EJ0120 datasheet and applies directly to the R5F526TBADFP#30. The 260 ps resolution enables precise dead-time control and reduced torque ripple in PMSM/BLDC motor drives, and it is maintained across the full operating voltage and temperature range of the R5F526TBADFP#30.
Is the R5F526TBADFP#30 certified for IEC60730 functional safety compliance?
The R5F526TBADFP#30 includes hardware features required for IEC60730 Class B compliance - including oscillation-stop detection, RAM test assist (DOC), CRCA, self-diagnostic A/D, analog input disconnection detection, and register write protection. These are documented in the "Useful functions for IEC60730 compliance" section of the R01DS0407EJ0120 datasheet. While the R5F526TBADFP#30 itself is not pre-certified, it provides the necessary on-chip mechanisms to implement a certified safety firmware layer. Customers must complete their own system-level validation per IEC60730-1.
What package type and pin count does the R5F526TBADFP#30 use?
The R5F526TBADFP#30 uses the PLQP0100KB-B package: a 100-pin Low-Profile Quad Flat Package (LFQFP) with 14 mm × 14 mm body size, 0.5 mm lead pitch, and exposed thermal pad. This package is explicitly listed in the "Package Information" section of the R01DS0407EJ0120 datasheet as applicable to the R5F526TBADFP#30. It provides 82 general-purpose I/O pins, two 5-V tolerant inputs, and dedicated pins for CAN FD, high-resolution PWM, and simultaneous A/D sampling - all physically realized in this 100-pin configuration.
