Product details
Overview
R5F52317ADLA#20 from Renesas is a 32-bit RXv2 microcontroller with 384 KB on-chip flash, 54 MHz max CPU frequency, IEEE 754-compliant FPU, and integrated 12-bit A/D (24 channels), 12-bit D/A (2 channels), USB 2.0 full-speed host/function/OTG, CAN, capacitive touch sensing (24 keys), and TSIP-Lite encryption. It targets industrial HMI, smart sensor nodes, and embedded control requiring real-time processing, secure firmware, and mixed-signal interfacing.
For engineers reviewing the R5F52317ADLA#20 datasheet, R5F52317ADLA#20 pinout, R5F52317ADLA#20 application, or R5F52317ADLA#20 equivalent, this page delivers verified specifications, package mapping to PTLG0100KA-A (5.5 × 5.5 mm TFLGA), functional pinout, real-world use cases, and two validated alternative parts for design flexibility.
Technical Context
The R5F52317ADLA#20 implements the RXv2 CPU core with 5-stage CISC Harvard pipeline, 88.56 DMIPS at 54 MHz, and hardware FPU for deterministic floating-point math. Its clock system includes main oscillator (1–20 MHz), sub-clock (32.768 kHz), PLL (4–12.5 MHz input), and USB-dedicated PLL enabling concurrent 54 MHz ICLK and 48 MHz USBCLK.
Peripheral integration centers on event-driven operation via ELC: 61 event sources trigger timer starts, A/D conversions, or DMA transfers without CPU intervention. The MCU supports IEC60730 safety compliance with self-diagnostic A/D, RAM test assistance, and clock accuracy measurement (CAC).
