FAQ

What is the maximum operating frequency and CPU performance of the R5F523T5AGFM#30?

The R5F523T5AGFM#30 operates at a maximum frequency of 40 MHz and delivers 65.6 DMIPS of processing performance using the RXv2 32-bit CPU core. Its 5-stage pipeline, variable-length instruction set, and hardware divider enable deterministic execution of motor control algorithms, with typical FOC loop times under 10 µs when leveraging the integrated FPU and MTU3c timer unit.

Does the R5F523T5AGFM#30 support IEC 60730 Class B compliance for safety-critical motor applications?

Yes, the R5F523T5AGFM#30 includes multiple hardware features to support IEC 60730 Class B compliance: self-diagnostic functions for the 12-bit ADC and comparator C, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with dedicated oscillator, RAM test assistance via the data operation circuit (DOC), and analog input disconnection detection - all documented in the R01DS0248EJ0110 datasheet.

What PWM capabilities does the R5F523T5AGFM#30 provide for 3-phase inverter control?

The R5F523T5AGFM#30 integrates the MTU3c timer unit with six 16-bit channels supporting three-phase complementary PWM output across two independent sets. Each set provides non-overlapping waveform generation, automatic dead-time insertion, adjustable duty cycle (0–100%), and reset-synchronized PWM mode - enabling direct control of 6-switch inverter bridges without external logic or gate driver timing compensation.

What is the analog peripheral configuration of the R5F523T5AGFM#30, and how is it used in motor current sensing?

The R5F523T5AGFM#30 features a 12-bit S12ADE ADC with 10 input channels, three integrated sample-and-hold circuits, double data registers, and comparator C (3 channels). For motor current sensing, AN000–AN007 accept shunt voltage signals; per-channel sampling time control and simultaneous A/D trigger generation from MTU3c ensure synchronized capture of phase currents at precise PWM center points - critical for accurate FOC implementation.

What package and pin count does the R5F523T5AGFM#30 use, and what are its thermal characteristics?

The R5F523T5AGFM#30 uses the PLQP0064KB-C package: a 64-pin LFQFP with 10 × 10 mm body, 0.5 mm pitch, and exposed thermal pad. This package supports junction-to-ambient thermal resistance (θ_JA) of ≤45°C/W under standard PCB layout conditions, enabling reliable operation at full 40 MHz in motor drive applications up to +105°C ambient - validated per the G-version industrial temperature specification.
