Renesas R5F524UCAGFB#30

Overview

R5F524UCAGFB#30 from Renesas 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#30 datasheet, R5F524UCAGFB#30 pinout, R5F524UCAGFB#30 application, or R5F524UCAGFB#30 equivalent, key selection considerations include its 144-pin LFQFP package, IEC60730 safety support, dual 8-bit DAC outputs usable as comparator references, and MTU3/GPT-based PWM timing precision for real-time motor phase control.

Technical Context

The R5F524UCAGFB#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions, enabling single-cycle execution for most operations and 153.6 DMIPS at 80 MHz. It integrates an IEEE 754-compliant 32-bit floating-point unit and hardware divider with two-cycle minimum latency.

Its peripheral subsystem includes a 12-bit S12ADF ADC with three independent units (5/5/12 channels), programmable gain amplifiers (1+3 channels), and sample-and-hold on Unit 1 - all synchronized via MTU3-triggered start requests. The RSCAN CAN module supports standard/extended frames across 16 message boxes with dedicated RAM buffers.
