Product details
Overview
R5F523T3ADFL#30 from Renesas is a 32-bit RX CPU-based microcontroller optimized for motor control and industrial inverter applications, operating at up to 40 MHz with 65.6 DMIPS performance, integrated FPU (IEEE 754 single-precision), 64 KB on-chip flash, 12 KB SRAM, and a 12-bit A/D converter with three sample-and-hold circuits - deployed in HVAC compressors, servo drives, and BLDC motor controllers.
For engineers reviewing the R5F523T3ADFL#30 datasheet, R5F523T3ADFL#30 pinout, R5F523T3ADFL#30 application, or R5F523T3ADFL#30 equivalent, this page delivers verified specifications, package mapping to PLQP0048KB-B (48-pin LFQFP, 7 × 7 mm, 0.5 mm pitch), MTU3c timer architecture for three-phase PWM generation, IEC60730-compliant self-diagnostic features, and confirmed alternative part selection guidance.
Technical Context
The R5F523T3ADFL#30 implements the RX v2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions - supporting 32-bit multiply-accumulate, 16-bit multiply-subtract, and hardware divider (2-cycle min). It integrates a dedicated clock frequency accuracy measurement circuit (CAC) and independent watchdog timer (IWDT) driven by a 15-kHz on-chip oscillator.
Its peripheral set centers on motor control: MTU3c provides six 16-bit channels with complementary PWM output, automatic dead-time insertion, phase counting, and A/D trigger synchronization; S12ADE delivers 10-channel 12-bit conversion at 1.0 µs/ch (40 MHz ADCLK); and RIIC/SCIg/RSPI interfaces enable system-level communication with gate drivers, sensors, and host controllers.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F523T5ADFL#30 | 128 KB flash (vs. 64 KB), same 48-pin LFQFP package, identical peripherals and clocking | Required when firmware exceeds 64 KB or future-proofing for feature expansion is needed | Select R5F523T5ADFL#30 if bootloader, safety libraries, or field-upgrade capability demand extra flash space |
| R5F523T3ADFD#30 | 52-pin LQFP (0.65 mm pitch), adds 13 additional I/O pins and one extra SCI channel vs. 48-pin variant | Suitable for designs needing more GPIOs or dual SCI interfaces (e.g., host + debug port) | Choose R5F523T3ADFD#30 only when board layout accommodates larger footprint and extra pins are utilized |
Compared with R5F523T3ADFL#30, R5F523T5ADFL#30 offers doubled flash capacity without changing pinout or timing behavior, while R5F523T3ADFD#30 trades compactness for I/O scalability - making the FL variant optimal for cost-sensitive, space-constrained motor control where 64 KB suffices.
