Renesas R5F523T5AGFL#30

Overview

R5F523T5AGFL#30 from Renesas is a 32-bit RX CPU-based microcontroller optimized for motor control and industrial inverter applications, operating at 40 MHz with 65.6 DMIPS performance, integrated 128 KB flash/12 KB SRAM, IEEE 754-compliant FPU, and dual three-phase complementary PWM outputs for real-time motor drive execution.

For engineers reviewing the R5F523T5AGFL#30 datasheet, R5F523T5AGFL#30 pinout, R5F523T5AGFL#30 application, or R5F523T5AGFL#30 equivalent, this page delivers verified specifications, package mapping to PLQP0048KB-B (48-pin LFQFP, 7×7 mm, 0.5 mm pitch), confirmed MTU3c timer architecture, IEC60730 self-diagnostic support, and direct alternative part comparisons for embedded motor control design validation.

Technical Context

The R5F523T5AGFL#30 implements the RX v2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling single-cycle execution for most operations and 65.6 DMIPS at 40 MHz. It integrates a dedicated 14-bit independent watchdog timer (IWDT) driven by a 15-kHz on-chip oscillator and supports IEC60730 Class B compliance via hardware-assisted RAM test, ADC disconnection detection, and clock accuracy measurement (CAC).

Its peripheral set centers on high-precision motor timing: six-channel MTU3c unit delivers three-phase complementary PWM with automatic dead-time insertion, phase counting, and A/D trigger synchronization; dual SCI channels support asynchronous, smart card, simplified SPI/I²C modes; and the 12-bit S12ADE ADC provides 10 channels with three sample-and-hold circuits, double data registers, and comparator integration for closed-loop current/voltage sensing.

FAQ

What is the maximum operating frequency and CPU performance of the R5F523T5AGFL#30?

The R5F523T5AGFL#30 operates at a maximum frequency of 40 MHz and delivers 65.6 DMIPS of processing performance. This is achieved through its 32-bit RX v2 CPU core with 5-stage pipeline and variable-length instruction architecture, enabling deterministic execution for real-time motor control loops. The R5F523T5AGFL#30 sustains this performance across its full −40°C to +105°C operating range.

Does the R5F523T5AGFL#30 support IEC60730 Class B functional safety requirements?

Yes, the R5F523T5AGFL#30 includes hardware features for IEC60730 Class B compliance: self-diagnostic ADC, clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT) with dedicated oscillator, RAM test assistance via Data Operation Circuit (DOC), and analog input disconnection detection. These capabilities are documented in the R01DS0248EJ0110 datasheet and reduce software certification burden for R5F523T5AGFL#30-based systems.

What package type and pin count does the R5F523T5AGFL#30 use?

The R5F523T5AGFL#30 uses the PLQP0048KB-B package: a 48-pin Low-Profile Quad Flat Package with 7 mm × 7 mm body size and 0.5 mm pin pitch. This package is confirmed in Table 1.4 and Figure 1.5 of the R01DS0248EJ0110 datasheet and matches the "FL" suffix in the part number. It includes an exposed thermal pad for enhanced heat dissipation in motor control applications.

How many PWM channels and what motor control features does the R5F523T5AGFL#30 provide?

The R5F523T5AGFL#30 integrates the MTU3c timer unit with six independent channels, supporting two complete sets of three-phase complementary PWM outputs. Key motor control features include automatic dead-time insertion, reset-synchronized PWM, phase counting mode, A/D conversion trigger synchronization, and port output enable (POE) for fault-induced high-impedance state. These are implemented in hardware and require no CPU overhead during operation of the R5F523T5AGFL#30.

What are the memory resources available on the R5F523T5AGFL#30?

The R5F523T5AGFL#30 includes 128 KB of on-chip flash memory (with no wait states up to 32 MHz) and 12 KB of SRAM (with no wait states at 40 MHz). Both memory blocks support background operation and are accessible via separate buses to avoid contention. The R5F523T5AGFL#30 also supports serial programming and self-programming for field firmware updates without external tools.
