Overview

R5F524UCAGFB#10 from Renesas Electronics is a 32-bit RXv2 core microcontroller with 384 KB on-chip flash, 32 KB SRAM, and 8 KB data flash, operating at up to 80 MHz (153.6 DMIPS), featuring integrated FPU, 12-bit ADC with 3-channel simultaneous sampling, CAN interface (ISO11898-1), and three-phase complementary PWM for motor control in industrial inverters.

For engineers reviewing the R5F524UCAGFB#10 datasheet, R5F524UCAGFB#10 pinout, R5F524UCAGFB#10 application, or R5F524UCAGFB#10 equivalent, key selection considerations include its 144-pin LFQFP package, 5-V tolerant I/O, IEC60730 safety support, and dual 8-bit DAC outputs usable as comparator references.

Technical Context

The R5F524UCAGFB#10 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and on-chip MPU for memory protection. It integrates a dedicated IWDT with 15-kHz oscillator and supports IEEE754-compliant single-precision floating-point operations via hardware FPU.

Clock management includes main oscillator (1–20 MHz), PLL (4–12.5 MHz input), and multiple on-chip oscillators with CAC for real-time accuracy monitoring. Peripheral clock domains are segmented: ICLK (80 MHz), PCLKA (80 MHz for MTU3/GPT/SCI11), PCLKB (40 MHz), PCLKD (40 MHz for ADC), and FCLK (32 MHz).

FAQ

What is the maximum operating frequency and DMIPS rating of the R5F524UCAGFB#10?

The R5F524UCAGFB#10 operates at a maximum frequency of 80 MHz and delivers 153.6 DMIPS (Dhrystone MIPS) performance. This is achieved by the RXv2 CPU core with 5-stage pipeline, hardware divider, and barrel shifter. The R5F524UCAGFB#10 maintains zero-wait-state access to 32 KB SRAM at this speed, enabling deterministic real-time execution critical for motor control loops.

Does the R5F524UCAGFB#10 support IEC60730 Class B compliance out of the box?

Yes, the R5F524UCAGFB#10 includes dedicated hardware features for IEC60730 Class B compliance: self-diagnostic A/D converter, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with dedicated oscillator, RAM test assistance using the DOC, and analog input disconnection detection. These capabilities are documented in the R01DS0278EJ0100 datasheet and reduce external component count for safety certification. The R5F524UCAGFB#10 implements them without requiring additional ICs.

How many ADC channels does the R5F524UCAGFB#10 support, and what is its simultaneous sampling capability?

The R5F524UCAGFB#10 integrates three 12-bit S12ADF units totaling 22 channels: unit 0 (5 channels), unit 1 (5 channels), and unit 2 (12 channels). Unit 1 includes a 3-channel simultaneous sample-and-hold circuit, enabling true concurrent sampling for motor phase current reconstruction. Each channel supports programmable sampling time and gain (via integrated PGA), and group scan priority control allows prioritized conversion sequencing. This configuration is fixed for the R5F524UCAGFB#10 per its package and memory variant.

What communication interfaces are available on the R5F524UCAGFB#10, and is CAN included?

The R5F524UCAGFB#10 includes CAN (RSCAN module, ISO11898-1 compliant, 16 message boxes), six SCI channels (with asynchronous, clock-synchronous, simple I²C, and simple SPI modes), one I²C bus interface (RIIC, up to 400 kbps), and one serial peripheral interface (RSPI, up to 20 Mbps). CAN is fully integrated and pin-assigned on the 144-pin LFQFP package. All interfaces support hardware-triggered DMA transfers via the DTC, reducing CPU overhead in high-throughput applications like industrial networking.

What is the package type and pin count of the R5F524UCAGFB#10, and are its I/O pins 5-V tolerant?

The R5F524UCAGFB#10 uses the PLQP0144KA-B package: a 144-pin Low-profile Quad Flat Package with 20 mm × 20 mm body and 0.5 mm lead pitch. Its general-purpose I/O ports include 5-V tolerant pins-specifically two pins designated as 5-V tolerant in the datasheet-allowing direct interfacing with legacy 5 V logic without level shifters. The full I/O count is 110 pins, with open-drain, pull-up, and driving-capacity switching support across most ports.
