For engineers reviewing the R5F526TBCDND#10 datasheet, R5F526TBCDND#10 pinout, R5F526TBCDND#10 application, or R5F526TBCDND#10 equivalent, key selection criteria include its 120 MHz real-time PWM timing resolution (260 ps minimum), dual-bank flash for safe firmware updates, IEC60730-compliant safety features including oscillation-stop detection and RAM test assistance, and support for simultaneous sampling across three 12-bit A/D units.

Technical Context

The R5F526TBCDND#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. It integrates dedicated motor control peripherals including 8-channel 32-bit GPTWa timers supporting 10-channel single-phase, 3-channel 3-phase, and 2-channel 5-phase complementary PWM modes.

Clock architecture includes a PLL-synchronized 120 MHz system clock (ICLK), independent PCLKA/PCLKC domains enabling concurrent high-speed peripheral operation (e.g., MTU3d at 120 MHz, S12ADH at 60 MHz ADCLK), and an IWDT-dedicated 120 kHz oscillator for fail-safe timing. Safety functions include MPU, Trusted Memory (TM), CRC calculator (CRCA), and register write protection.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TBCDND#10?

The R5F526TBCDND#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance stems from the RXv3 CPU core's single-cycle instruction execution, 32-bit multiplier/divider, and barrel shifter-enabling deterministic real-time response for motor control loops. The R5F526TBCDND#10 sustains this speed across all memory and peripheral accesses without wait states.

Does the R5F526TBCDND#10 support CAN FD, and what standard does it comply with?

Yes, the R5F526TBCDND#10 integrates a CAN FD module compliant with ISO11898-1:2015, supporting both standard and extended frames. It enables data rates up to 5 Mbps in FD mode while maintaining backward compatibility with classical CAN networks. The R5F526TBCDND#10 uses dedicated CAN_TX/CAN_RX pins and includes message RAM with configurable mailboxes for deterministic interrupt handling in real-time motor control systems.

What PWM resolution and complementary output capabilities does the R5F526TBCDND#10 provide?

The R5F526TBCDND#10 delivers 260 ps minimum timing resolution via its 4-channel HRPWM circuit applied to GPTW0–GPTW3 outputs. It supports 10-channel single-phase, 3-channel 3-phase, and 2-channel 5-phase complementary PWM modes with automatic dead-time insertion. The R5F526TBCDND#10 uses POE3D and POEG modules to safely disable outputs during fault conditions-critical for inverter gate driver reliability.

How does the R5F526TBCDND#10 support IEC60730 functional safety compliance?

The R5F526TBCDND#10 includes multiple hardware features for IEC60730 Class B compliance: oscillation-stop detection for main clock failure, self-diagnostic A/D converter, RAM test assistance using DOC, independent watchdog timer (IWDT) with window function, CRC calculator (CRCA), and register write protection. These features are documented in Renesas' RX26T Functional Safety Manual (R01UM0145EJ0100), and the R5F526TBCDND#10 is qualified for use in safety-critical motor control applications.

What package type and pin count does the R5F526TBCDND#10 use?

The R5F526TBCDND#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 package supports 83 general-purpose I/O pins-including 5-V tolerant, open-drain, and large-current drive variants-and is rated for operation from –40°C to +85°C (D-version). The R5F526TBCDND#10's pinout is fully documented in Section 2.2 of R01DS0407EJ0120.
