For engineers reviewing the R5F526TBADFM#30 datasheet, R5F526TBADFM#30 pinout, R5F526TBADFM#30 application, or R5F526TBADFM#30 equivalent, key selection criteria include its 120 MHz GPTWa timer with 3-phase/5-phase complementary PWM, dual-bank flash for safe firmware updates, Trusted Secure IP Lite encryption, and 83-pin PLQP0100KB-B package with 5-V-tolerant I/Os.

Technical Context

The R5F526TBADFM#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. Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator - enabling independent peripheral clock domains (PCLKA up to 120 MHz, PCLKB up to 60 MHz).

Motor control is enabled by tightly coupled peripherals: MTU3d (9-channel 16-bit timer) and GPTWa (8-channel 32-bit timer) both synchronized to PCLKC at up to 120 MHz, HRPWM (4-channel) for sub-nanosecond PWM edge placement, and ELC for interrupt-free inter-module event chaining - including A/D trigger generation and dead-time compensation.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TBADFM#30?

The R5F526TBADFM#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark points under benchmark conditions. This performance stems from the RXv3 CPU core's single-cycle instruction execution, 32-bit multiplier/divider, and barrel shifter - all validated in the official Renesas R01DS0407EJ0120 datasheet. The R5F526TBADFM#30 sustains full-speed operation across its entire voltage range (2.7–5.5 V) and temperature range (–40°C to +85°C).

Does the R5F526TBADFM#30 support CAN FD, and what standard does it comply with?

Yes, the R5F526TBADFM#30 integrates a single-channel CAN FD module compliant with ISO 11898-1:2015, supporting both standard (11-bit) and extended (29-bit) frame formats. It enables data rates up to 5 Mbps in the data phase while maintaining backward compatibility with classical CAN. This capability is confirmed in Section 1.1 and Table 1.1 of the R01DS0407EJ0120 datasheet, and the R5F526TBADFM#30 uses dedicated CANH/CANL pins in its PLQP0100KB-B package.

What PWM resolution and channel count does the R5F526TBADFM#30 provide for motor control?

The R5F526TBADFM#30 provides three layered PWM resources: 8-channel 32-bit GPTWa timers, 9-channel 16-bit MTU3d timers, and 4-channel High-Resolution PWM (HRPWM) with a minimum timing resolution of 260 ps at 120 MHz. This enables single-phase (10 outputs), 3-phase (3 outputs), and 5-phase (2 outputs) complementary PWM generation with automatic dead-time insertion - all documented in the "Timers" section of the R01DS0407EJ0120 datasheet for the R5F526TBADFM#30.

How does the R5F526TBADFM#30 support IEC60730 functional safety compliance?

The R5F526TBADFM#30 includes multiple hardware features certified for IEC60730 Class B: oscillation-stop detection, RAM test assist (via DOC), CRC calculator (CRCA), independent watchdog timer (IWDTa) with window function, register write protection, and self-diagnostic A/D functions. These are explicitly listed in the "Useful functions for IEC60730 compliance" section of the R01DS0407EJ0120 datasheet and apply directly to the R5F526TBADFM#30 device variant.

What is the package type and pin count of the R5F526TBADFM#30?

The R5F526TBADFM#30 is packaged in a PLQP0100KB-B - a 100-pin low-profile quad flat package measuring 14 × 14 mm with 0.5 mm pitch. It provides 83 general-purpose I/O pins (including 2×5-V tolerant and 15×large-current drive), plus dedicated power, ground, clock, reset, and debug pins. This package information is specified in the "Package Information" section of the R01DS0407EJ0120 datasheet and confirmed for the R5F526TBADFM#30 orderable part number.
