Renesas R5F513T3ADNH#20

Overview

R5F513T3ADNH#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 max CPU clock, 128 KB on-chip Flash (SuperFlash®), 16 KB RAM, and dedicated hardware timers including MTU3 and POEG for precise three-phase PWM generation with dead-time insertion. The device supports single-supply operation from 2.7–5.5 V and targets brushless DC (BLDC) and permanent magnet synchronous motor (PMSM) drives.

For engineers reviewing the R5F513T3ADNH#20 datasheet, R5F513T3ADNH#20 pinout, R5F513T3ADNH#20 application, or R5F513T3ADNH#20 equivalent, key selection criteria include integrated motor timing peripherals, Flash endurance (100k write/erase cycles), operating temperature range (−40 to +85 °C), and LFQFP-48 package compatibility with industrial motor control PCB layouts.

Technical Context

The R5F513T3ADNH#20 implements the RXv1 CPU core with 32-bit CISC architecture, 5-stage pipeline, and hardware multiply/divide. It features a dedicated Motor Timer Unit 3 (MTU3) supporting complementary PWM outputs with programmable dead-time, phase-shift, and synchronization across multiple channels - essential for field-oriented control (FOC) of three-phase inverters.

System-level integration includes a 12-bit ADC with 1.1 μs conversion time and simultaneous sampling across up to 4 channels, plus a programmable gain amplifier (PGA) for current sensing. Clock management uses an on-chip PLL with fractional divider and independent oscillators (sub-clock, IWDT, BCLK) enabling robust startup and fail-safe timing in variable-speed drive systems.

FAQ

What is the maximum operating frequency of the R5F513T3ADNH#20 CPU core?

The R5F513T3ADNH#20 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, supporting stable operation across the full −40 to +85 °C temperature range. The 5-stage pipeline and hardware multiply/divide enable efficient execution of motor control algorithms in the R5F513T3ADNH#20 without external acceleration.

Does the R5F513T3ADNH#20 support hardware-based dead-time insertion for three-phase PWM?

Yes, the R5F513T3ADNH#20 includes the MTU3 (Motor Timer Unit 3), which provides hardware-configurable dead-time insertion on complementary PWM outputs. Dead-time can be set in increments as fine as 1 ns and is applied automatically across all six output channels. This capability is integral to safe inverter switching in the R5F513T3ADNH#20 and eliminates software overhead or external logic for shoot-through prevention.

What ADC capabilities does the R5F513T3ADNH#20 offer for motor current sensing?

The R5F513T3ADNH#20 integrates a 12-bit SAR ADC with 1.1 μs conversion time and supports simultaneous sampling across up to four channels. It includes a programmable gain amplifier (PGA) on select inputs (AD00–AD03) for direct low-side shunt amplification. These features enable accurate dual-shunt current reconstruction - a critical function for field-oriented control implemented in the R5F513T3ADNH#20.

Is the R5F513T3ADNH#20 pin-compatible with other devices in the RX13T Group?

The R5F513T3ADNH#20 in the 48-pin LFQFP package shares identical pin assignments with other RX13T Group members in the same package variant (e.g., R5F513T5ADNH#20). However, pin compatibility does not extend to devices in different packages (e.g., 32-pin LQFP) or variants lacking certain peripherals like POEG. Always verify peripheral mapping and register configuration when migrating to another RX13T part, even within the same R5F513T3ADNH#20 family.

What is the Flash endurance specification for the R5F513T3ADNH#20?

The R5F513T3ADNH#20 uses SuperFlash® technology for its 128 KB on-chip Flash memory, rated for 100,000 write/erase cycles and data retention exceeding 20 years at +85 °C. This endurance supports robust field firmware updates and runtime parameter storage in motor control applications where the R5F513T3ADNH#20 operates continuously under industrial conditions.
