Product details
Overview
R5F52315ADLA#20 from Renesas is a 32-bit RXv2 microcontroller with 54 MHz max operating frequency, 128 KB on-chip flash memory, 32 KB SRAM, and 8 KB data flash. It integrates a single-precision IEEE 754 FPU, 12-bit 24-channel ADC (0.83 µs conversion), dual 12-bit DACs, USB 2.0 full-speed host/function/OTG, CAN interface, RTC, capacitive touch sensing unit (24-key support), and TSIP-Lite encryption engine. It targets industrial HMI and smart sensor nodes requiring secure, low-power, mixed-signal control.
For engineers reviewing the R5F52315ADLA#20 datasheet, R5F52315ADLA#20 pinout, R5F52315ADLA#20 application, or R5F52315ADLA#20 equivalent, key selection criteria include its 5.5 × 5.5 mm TFLGA package, −40 to +85°C temperature grade, absence of SDHI and CAN in this variant, and compatibility with Renesas' RX family toolchain and E2 studio IDE.
Technical Context
The R5F52315ADLA#20 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling 88.56 DMIPS at 54 MHz. It supports little-endian data and instruction layout, includes an MPU for memory protection, and features fast interrupt response with 167 vector entries.
Its clock system combines main (1–20 MHz), sub-clock (32.768 kHz), and on-chip oscillators (low/high-speed), with dedicated PLLs for system (54 MHz), USB (48 MHz), and IWDT clocks. The ELC enables event-driven peripheral operation without CPU intervention, supporting low-power execution during sleep modes.
