Renesas R5F523T5AGFL#10

Overview

R5F523T5AGFL#10 from Renesas is a 40-MHz 32-bit RXv2 CPU-based microcontroller optimized for inverter motor control, featuring integrated FPU (IEEE 754 single-precision), 128-KB flash, 12-KB SRAM, and dual three-phase complementary PWM outputs via MTU3c. It operates from 2.7–5.5 V across −40 to +105°C and integrates 10-channel 12-bit ADC with three sample-and-hold circuits and comparator C.

For engineers reviewing the R5F523T5AGFL#10 datasheet, R5F523T5AGFL#10 pinout, R5F523T5AGFL#10 application, or R5F523T5AGFL#10 equivalent, key selection criteria include IEC60730-compliant self-diagnostic features, 40-MHz PWM timing accuracy, on-chip CAC for clock validation, and 48-pin LFQFP (7 × 7 mm, 0.5 mm pitch) package compatibility with industrial motor drive layouts.

Technical Context

The R5F523T5AGFL#10 implements a CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and 65.6 DMIPS performance at 40 MHz. Its RXv2 core includes dual 72-bit accumulators, 32-bit multiplier/divider, barrel shifter, and memory protection unit (MPU) for safety-critical execution.

Peripherals are clocked independently: ICLK (system) and PCLKA/B/D (peripheral) all support 40 MHz operation, enabling simultaneous high-speed PWM generation (MTU3c), ADC sampling (1.0 µs min conversion time), and SCI/RSPI communication without bus contention.

FAQ

What is the maximum operating frequency and associated performance of the R5F523T5AGFL#10?

The R5F523T5AGFL#10 operates at a maximum frequency of 40 MHz, delivering 65.6 DMIPS of processing performance. This enables sub-25 µs execution of field-oriented control (FOC) loops, critical for high-speed BLDC and PMSM motor applications. The RXv2 core's 5-stage pipeline and variable-length instruction set ensure efficient code density and deterministic interrupt latency.

Does the R5F523T5AGFL#10 support IEC60730 compliance for household appliances?

Yes, the R5F523T5AGFL#10 includes dedicated hardware features for IEC60730 Class B compliance: self-diagnostic routines for the ADC, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT), RAM test assistance via DOC, and analog input disconnection detection. These reduce external component count and simplify certification efforts.

What PWM capabilities does the R5F523T5AGFL#10 provide for inverter control?

The R5F523T5AGFL#10 integrates the MTU3c timer unit, supporting two independent sets of three-phase complementary PWM outputs with automatic dead-time insertion, adjustable duty cycle (0–100%), and reset-synchronized operation. It also provides phase counting mode and A/D conversion trigger generation - all essential for precise inverter gate driving without external logic.

What is the ADC resolution, channel count, and key timing specification of the R5F523T5AGFL#10?

The R5F523T5AGFL#10 features a 12-bit S12ADE ADC with 10 input channels, three independent sample-and-hold circuits, and a minimum conversion time of 1.0 µs when ADCLK runs at 40 MHz. Sampling time per channel is individually configurable, and the ADC supports group scan mode with priority control for time-critical current sensing in motor control.

Which package type and pin count does the R5F523T5AGFL#10 use?

The R5F523T5AGFL#10 uses a 48-pin LFQFP package (PLQP0048KB-B) with 7 × 7 mm body size and 0.5 mm pitch. This compact footprint supports high-density PCB layouts typical in inverter modules, while providing 37 general-purpose I/O pins, 10 ADC inputs, and dedicated MTU3c waveform output pins for three-phase motor control.
