For engineers reviewing the R5F526T9ADFN#30 datasheet, R5F526T9ADFN#30 pinout, R5F526T9ADFN#30 application, or R5F526T9ADFN#30 equivalent, key selection criteria include its 48 KB RAM configuration, 64-pin HWQFN (PWQN0064KF-A) package, dual-bank flash for safe firmware updates, 12-bit A/D converter with simultaneous sampling across two units (7+8 channels), and 3-phase complementary PWM capability via MTU3d and GPTWa timers.

Technical Context

The R5F526T9ADFN#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16 register banks for fast context switching-enabling deterministic real-time motor control loops. Its clock system integrates PLL with external 8–24 MHz crystal reference, internal HOCO (16/18/20 MHz), and dedicated 120 kHz IWDT oscillator.

Peripheral coordination is managed through the Event Link Controller (ELC), which enables 183 internal event signals-including MTU3d compare-match, GPTWa PWM triggers, and A/D conversion starts-to initiate module operations without CPU intervention, even during sleep mode. The device uses PCLKA (up to 120 MHz) for high-speed peripherals like MTU3d and GPTWa, while PCLKD (up to 60 MHz) clocks the 12-bit S12ADH A/D converter at 0.9 µs minimum conversion time per channel.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526T9ADFN#30?

The R5F526T9ADFN#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark points under benchmark conditions. This performance level is enabled by the RXv3 CPU core's single-cycle instruction execution, 16 register banks, and integrated 32-bit multiplier/divider - making the R5F526T9ADFN#30 suitable for computationally intensive field-oriented control (FOC) algorithms in real-time motor applications.

Does the R5F526T9ADFN#30 support IEC60730 Class B compliance out of the box?

Yes, the R5F526T9ADFN#30 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stop detection, RAM test assist via DOC, CRCA for data integrity, register write protection, and self-diagnostic A/D functions. These capabilities reduce reliance on external components and simplify certification - though final system-level validation remains the responsibility of the end equipment manufacturer using the R5F526T9ADFN#30.

What package type and pin count does the R5F526T9ADFN#30 use?

The R5F526T9ADFN#30 uses the PWQN0064KF-A package: a 64-pin HWQFN with 9 × 9 mm body size, 0.5 mm pitch, and exposed thermal pad. It provides 49 general-purpose I/O pins, including 5-V tolerant inputs, and is optimized for thermal dissipation in compact inverter modules where the R5F526T9ADFN#30 serves as the primary motor control MCU.

How many A/D converter channels does the R5F526T9ADFN#30 support, and what is their configuration?

The R5F526T9ADFN#30 includes the S12ADH 12-bit A/D converter with two independent units: Unit 0 (7 channels) and Unit 2 (8 channels), totaling 15 channels. Both units support simultaneous sampling triggered by MTU3d or GPTWa events - critical for accurate three-phase current reconstruction in motor control. Minimum conversion time is 0.9 µs per channel when ADCLK runs at 60 MHz.

Is CAN FD supported on the R5F526T9ADFN#30, and what standard does it comply with?

Yes, the R5F526T9ADFN#30 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames with data rates up to 5 Mbps. This enables high-bandwidth telemetry from motor controllers to central ECUs in industrial automation and EV systems - a key differentiator over legacy CAN implementations in the R5F526T9ADFN#30's target applications.
