FAQ

What is the maximum operating frequency of the R5F513T3AGNE#20 CPU core?

The R5F513T3AGNE#20 features the RXv1 32-bit CPU core with a maximum operating frequency of 48 MHz. This frequency is achieved using the on-chip PLL with an external crystal or ceramic resonator. The core delivers 1.25 DMIPS/MHz performance, enabling sub-microsecond interrupt response times critical for real-time motor commutation. All timing specifications in the R5F513T3AGNE#20 datasheet assume operation at this rated frequency under specified voltage and temperature conditions.

Does the R5F513T3AGNE#20 support hardware-based field-oriented control (FOC)?

Yes, the R5F513T3AGNE#20 supports hardware-accelerated FOC through tight integration of its MTU3 timer, 12-bit ADC, and analog comparators. The MTU3 generates synchronized PWM waveforms with programmable dead time, while the ADC triggers conversions on MTU3 events for precise current sampling. Hardware comparator outputs can directly disable PWM outputs within 100 ns - enabling cycle-by-cycle overcurrent protection without CPU involvement. This architecture makes the R5F513T3AGNE#20 capable of executing full FOC loops in under 5 µs.

What package type and pin count does the R5F513T3AGNE#20 use?

The R5F513T3AGNE#20 is packaged in a 48-pin LFQFP (Low-profile Quad Flat Package) with 7 mm × 7 mm body size and 0.5 mm lead pitch. This package is RoHS-compliant and rated MSL3. It provides dedicated analog and digital power/ground pins, isolated PWM output banks, and configurable GPIOs - optimized for compact motor drive PCB layouts. The pinout matches other 48-pin RX13T variants, allowing design reuse across memory and feature variants.

Can the R5F513T3AGNE#20 operate from a 3.3 V supply only?

Yes, the R5F513T3AGNE#20 operates from a single 3.3 V nominal supply, with specified operation across 2.7 V to 3.6 V. Its internal regulators provide stable core and analog voltages regardless of input rail variation. The device includes low-voltage detection (LVD) circuitry that generates interrupts or resets when VCC drops below user-configurable thresholds (e.g., 2.85 V or 2.7 V), ensuring safe shutdown before logic corruption occurs. This makes the R5F513T3AGNE#20 compatible with standard 3.3 V industrial power supplies without external level-shifting.

Is the R5F513T3AGNE#20 qualified for industrial temperature range?

Yes, the R5F513T3AGNE#20 is fully qualified for the industrial temperature range of –40°C to +85°C. This rating is verified per Renesas' standard qualification tests (JESD22-A104, A108, A110) and applies to all electrical characteristics in the datasheet. The device's thermal design - including junction-to-case resistance and internal thermal shutdown - ensures reliable operation in enclosed motor drive environments without forced air cooling. Renesas classifies the R5F513T3AGNE#20 as a "Standard" grade product, intended for industrial equipment including HVAC, appliances, and factory automation.
