Renesas R5F513T5ADNH#20

Overview

R5F513T5ADNH#20 from Renesas Electronics is a 32-bit RXv1 core microcontroller in the RX13T Group, designed for motor control and power conversion applications. It integrates a 40 MHz CPU, 128 KB on-chip Flash (SuperFlash®), 16 KB RAM, hardware FPU, and dedicated motor control peripherals including three 16-bit timer units with complementary PWM outputs, a 12-bit ADC with 16 channels, and an encoder interface. It operates from 2.7–5.5 V and supports industrial temperature range (−40°C to +85°C).

For engineers reviewing the R5F513T5ADNH#20 datasheet, R5F513T5ADNH#20 pinout, R5F513T5ADNH#20 application, or R5F513T5ADNH#20 equivalent, key selection criteria include integrated high-resolution PWM timing, real-time ADC sampling synchronized to PWM cycles, on-chip op-amps for current sensing, and support for sensorless FOC algorithms - all in a compact 48-pin LFQFP package.

Technical Context

The R5F513T5ADNH#20 implements the RXv1 CPU core with 32-bit CISC architecture, 5-stage pipeline, and hardware FPU for deterministic motor control math. It features a dedicated Motor Control Timer (MTU3) with dead-time insertion, complementary output pairs, and synchronous trigger capability for ADC conversion.

Its peripheral set includes a 12-bit ADC with 1.0 μs conversion time, sample-and-hold circuitry, and hardware synchronization to MTU3 events; plus two independent op-amps with programmable gain (1×, 2×, 4×, 8×) and rail-to-rail input/output - enabling single-shunt or dual-shunt current sensing without external signal conditioning.

FAQ

What is the maximum operating frequency of the R5F513T5ADNH#20?

The R5F513T5ADNH#20 operates at a maximum CPU frequency of 40 MHz using its on-chip PLL, which can multiply the 4 MHz internal oscillator or an external crystal input. This frequency is fully supported across the entire −40°C to +85°C industrial temperature range and 2.7–5.5 V supply voltage, ensuring deterministic timing for motor control loops without derating.

Does the R5F513T5ADNH#20 support sensorless FOC algorithms out of the box?

Yes, the R5F513T5ADNH#20 includes hardware features essential for sensorless FOC: high-resolution MTU3 PWM with hardware dead-time insertion, ADC hardware triggering synchronized to PWM center points, and a hardware FPU for fast Clarke/Park transforms and PI control. Renesas provides validated motor control libraries (RX13T Motor Control Library) that run directly on the R5F513T5ADNH#20 without modification.

What package type and pin count does the R5F513T5ADNH#20 use?

The R5F513T5ADNH#20 uses a 48-pin LFQFP package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad. This package is pin-compatible across the RX13T Group, allowing direct substitution with R5F513T3ADNH#20 and R5F513T6ADNH#20 in existing PCB layouts - no redesign required when scaling memory capacity.

How many analog comparators are integrated into the R5F513T5ADNH#20?

The R5F513T5ADNH#20 integrates two analog comparators, each associated with one of its two rail-to-rail op-amps. These comparators support fast overcurrent detection (<100 ns response) and can be configured to generate interrupt requests or directly trigger PWM shutdown via the MTU3 fault input - enabling hardware-level protection independent of CPU intervention.

Is the R5F513T5ADNH#20 qualified for automotive applications?

No, the R5F513T5ADNH#20 is rated for industrial temperature range (−40°C to +85°C) and classified as a "Standard" quality grade device per Renesas documentation. It is not AEC-Q100 qualified and is not intended for automotive powertrain or safety-critical systems. For automotive motor control, Renesas recommends the RX23T or RX66T families instead.
