Renesas R5F524UEAGFP#50

Overview

R5F524UEAGFP#50 from Renesas Electronics is a 32-bit RXv2 microcontroller designed for industrial motor control and safety-critical embedded systems. It operates at up to 80 MHz (153.6 DMIPS), integrates a single-precision IEEE754 FPU, 512 KB on-chip flash, 32 KB SRAM, and 8 KB data flash with 1M erase/write cycles. It supports IEC60730-compliant self-diagnostic functions and delivers three-phase complementary PWM across two MTU3 channels.

For engineers reviewing the R5F524UEAGFP#50 datasheet, R5F524UEAGFP#50 pinout, R5F524UEAGFP#50 application, or R5F524UEAGFP#50 equivalent, key selection considerations include its 100-pin LFQFP package, CAN 2.0B compliance, 12-bit ADC with 3-channel simultaneous sampling, programmable gain amplifiers per unit, and hardware-assisted RAM/ADC/clock diagnostic features required for Class B appliance certification.

Technical Context

The R5F524UEAGFP#50 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and fast interrupt response. Its memory protection unit (MPU) enforces eight configurable regions with read/write/execute access control, while the register write protection function safeguards critical configuration registers against unintended overwrites.

Timing subsystems include dual clock domains: ICLK at 80 MHz for CPU/core logic, PCLKA at 80 MHz for MTU3/GPT/SCI11, and PCLKB at 40 MHz for most peripherals. The CAC circuit continuously monitors main oscillator, PLL, and on-chip oscillator accuracy against a reference, supporting real-time clock integrity verification for functional safety applications.

FAQ

What is the maximum operating frequency and performance rating of the R5F524UEAGFP#50?

The R5F524UEAGFP#50 operates at a maximum frequency of 80 MHz and delivers 153.6 DMIPS of processing performance. This is achieved using the RXv2 CPU core with a 5-stage pipeline, on-chip FPU, and optimized instruction set. The R5F524UEAGFP#50 maintains zero-wait-state access to its 32 KB SRAM at this speed, enabling deterministic real-time execution critical for motor control loops.

Does the R5F524UEAGFP#50 support IEC60730 Class B compliance out of the box?

Yes, the R5F524UEAGFP#50 includes hardware features essential for IEC60730 Class B certification: memory protection unit (MPU), data operation circuit (DOC) for RAM testing, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with dedicated oscillator, and ADC self-diagnostic functions. These capabilities are documented in the R01DS0278EJ0100 datasheet and require proper configuration-but no external components-to meet core diagnostic requirements. The R5F524UEAGFP#50 is designed for use in certified appliance control systems.

What ADC and PWM capabilities does the R5F524UEAGFP#50 provide for motor control?

The R5F524UEAGFP#50 integrates a 12-bit S12ADF ADC with 22 channels across three units-including 3-channel simultaneous sampling in Unit 1-and programmable gain amplifiers on four channels. For PWM, its MTU3 unit delivers two independent 3-phase complementary outputs with automatic dead-time insertion and phase counting mode. The R5F524UEAGFP#50 also supports GPT-based single-phase complementary and three-phase PWM with comparator interlocking, enabling precise inverter gate timing and current sensing synchronization.

What package type and pin count does the R5F524UEAGFP#50 use?

The R5F524UEAGFP#50 uses a 100-pin LFQFP package designated PLQP0100KB-B: 14 × 14 mm body size with 0.5 mm pitch. It provides 79 general-purpose I/O pins, 2 5-V tolerant inputs, and 61 open-drain outputs. Pin functions-including MTU3/GPT waveform I/O, ADC trigger outputs (ADSM0/ADSM1), and port output enable inputs (POE0#–POE12#)-are fully documented in the R01DS0278EJ0100 datasheet. The R5F524UEAGFP#50 shares pin compatibility with other RX24U 100-pin variants like R5F524UCAGFP#50.

Does the R5F524UEAGFP#50 include CAN interface support?

Yes, the R5F524UEAGFP#50 integrates a single-channel CAN module (RSCAN) compliant with ISO11898-1, supporting both standard and extended frames. It includes 16 message boxes with configurable acceptance filtering and FIFO functionality. The CAN peripheral operates independently of the main CPU clock domain and supports bit rates up to 1 Mbps. This makes the R5F524UEAGFP#50 suitable for industrial fieldbus communication and automotive subsystem integration where robust, deterministic messaging is required.
