It integrates a 40 MHz max CPU clock, 128 KB on-chip Flash (SuperFlash®), 16 KB RAM, and dedicated hardware accelerators including a 3-phase PWM timer (MTU3), encoder interface (ENCD), and analog comparator with hysteresis - all operating within −40°C to +105°C industrial temperature range.

For engineers reviewing the R5F513T3ADFL#30 datasheet, R5F513T3ADFL#30 pinout, R5F513T3ADFL#30 application, or R5F513T3ADFL#30 equivalent, key selection considerations include its integrated motor control peripherals, 12-bit ADC with 1.1 μs conversion time, 5 V-tolerant I/O capability, and support for single-shunt current sensing topologies in BLDC/PMSM drives.

Technical Context

The R5F513T3ADFL#30 implements the RXv1 CPU architecture with 32-bit CISC instruction set, 5-stage pipeline, and hardware multiplier/divider. It features a dual-bank Flash memory enabling read-while-write operation and supports secure boot via ROM-based bootloader with SCI/USB DFU capability.

Its system control includes a programmable PLL with fractional divider, independent watchdog timers (IWDT & WDT), and voltage monitor (VLS) with three detection levels. Peripheral integration centers on real-time motor control: MTU3 provides six complementary PWM outputs with dead-time insertion and fault protection, while the ENCD module supports quadrature decoding and index pulse capture up to 20 MHz.

FAQ

What is the maximum operating frequency of the R5F513T3ADFL#30 CPU core?

The R5F513T3ADFL#30 features an RXv1 32-bit CISC core with a maximum operating frequency of 40 MHz. This frequency is achieved using the on-chip PLL with fractional divider, which accepts input from internal or external oscillators. The 40 MHz clock enables sub-5 μs execution of critical motor control loops, meeting real-time requirements for field-oriented control at switching frequencies up to 20 kHz. All timing specifications in the R5F513T3ADFL#30 datasheet assume operation at this rated frequency under specified voltage and temperature conditions.

Does the R5F513T3ADFL#30 support encoder interface functionality?

Yes, the R5F513T3ADFL#30 includes a dedicated Encoder Interface (ENCD) module capable of quadrature decoding, index pulse capture, and overflow detection. It supports differential or single-ended A/B/Z inputs with programmable digital filtering and operates up to 20 MHz input frequency. This hardware block handles position counting and direction detection autonomously, freeing the CPU for control calculations. The ENCD is fully integrated with the MTU3 timer and ADC to synchronize motor commutation with mechanical position - a key capability confirmed in the RX13T Group User's Manual Hardware (Rev.1.10, Section 1.4).

What package type and pin count does the R5F513T3ADFL#30 use?

The R5F513T3ADFL#30 is supplied in a 48-pin LFQFP package (7 mm × 7 mm, 0.5 mm pitch) with an exposed thermal pad. This package provides 39 general-purpose I/O pins, including dedicated motor control functions such as MTU3 PWM outputs, ENCD inputs, and analog comparator terminals. Pin assignments are documented in Section 1.5.1 of the RX13T Group User's Manual: Hardware, and the package meets JEDEC standard MS-026 for surface-mount assembly. The "FL" suffix in R5F513T3ADFL#30 explicitly denotes this LFQFP variant.

Can the R5F513T3ADFL#30 perform single-shunt current sensing for FOC?

Yes, the R5F513T3ADFL#30 supports single-shunt field-oriented control through tightly coupled hardware features: the MTU3 timer generates synchronized PWM reload events that trigger the 12-bit ADC to sample shunt voltage at precise commutation points, while its dual-sample-and-hold capability allows reconstruction of all three phase currents from one shunt resistor. This capability is validated in Renesas Application Note R01AN3929EJ, which details the R5F513T3ADFL#30-based single-shunt FOC reference design with <2% current reconstruction error at 20 kHz switching.

Is the R5F513T3ADFL#30 qualified for industrial temperature range operation?

Yes, the R5F513T3ADFL#30 is rated for operation from −40°C to +105°C ambient temperature and classified as a "Standard" quality grade device per Renesas documentation. It meets industrial reliability requirements for motor control applications in harsh environments, including thermal cycling, humidity, and ESD immunity per IEC 61000-4-2 Level 3. The device's Flash memory includes ECC protection and the voltage monitor (VLS) provides three programmable reset thresholds - all features validated across the full temperature range and documented in the R5F513T3ADFL#30 datasheet (R01DS0341EJ).
