Product details
Overview
R5F52315AGFL#30 from Renesas is a 32-bit RXv2 microcontroller operating at up to 54 MHz (88.56 DMIPS), featuring 128 KB on-chip flash, 32 KB SRAM, 8 KB data flash, integrated FPU (IEEE 754 single-precision), and hardware encryption (TSIP-Lite AES-128/256). It supports USB 2.0 full-speed host/function/OTG, CAN, SD host interface, 24-channel 12-bit ADC (0.83 µs conversion), dual 12-bit DAC, RTC with battery backup, and capacitive touch sensing (24 keys) - deployed in industrial HMI and smart sensor nodes requiring deterministic real-time control and secure firmware updates.
For engineers reviewing the R5F52315AGFL#30 datasheet, R5F52315AGFL#30 pinout, R5F52315AGFL#30 application, or R5F52315AGFL#30 equivalent, this MCU delivers verified 54-MHz timing accuracy via CAC, ELC-driven event-triggered peripheral coordination without CPU wake-up, IEC60730-compliant self-test functions for A/D, IWDT, and RAM, and production-ready support for USB BC1.2 charging detection and SDIO 3.01 physical layer compliance.
Technical Context
The R5F52315AGFL#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. Its memory subsystem includes no-wait 54-MHz SRAM access, flash accelerator-assisted execution above 32 MHz, and background operation (BGO) for 8-KB data flash programming during active code execution.
Peripherals are orchestrated via the Event Link Controller (ELC), which routes 61 event signals directly between modules (e.g., TPU output compare → ADC start trigger) while the CPU remains in deep sleep. Clock domains are strictly partitioned: ICLK (54 MHz system clock), PCLKA (54 MHz for MTU2a), PCLKD (54 MHz for S12ADE), and BCLK (32 MHz for external bus), ensuring deterministic timing across mixed-criticality tasks.
