Product details
Overview
R5F52317BDNE#40 from Renesas is a 32-bit RXv2 microcontroller with 54 MHz max operating frequency, 384 KB on-chip flash memory, 32 KB SRAM, and integrated 12-bit A/D converter (24 channels), 12-bit D/A converter (2 channels), USB 2.0 full-speed host/function/OTG, CAN interface, capacitive touch sensing unit (24-key support), and hardware AES encryption (TSIP-Lite). It operates across −40 to +85°C and targets industrial HMI and secure embedded control applications.
For engineers reviewing the R5F52317BDNE#40 datasheet, R5F52317BDNE#40 pinout, R5F52317BDNE#40 application, or R5F52317BDNE#40 equivalent, key selection considerations include its 48-pin HWQFN (PWQN0048KB-A) package, absence of SDHI and CAN in this variant, RTC availability, and compatibility with Renesas' E2 studio and CS+ development tools.
Technical Context
The R5F52317BDNE#40 implements the RXv2 CPU core with IEEE 754-compliant 32-bit FPU, 32×32-bit multiplier, and 32-bit divider (2-cycle min latency). Its clock system supports main oscillator (1–20 MHz), sub-clock (32.768 kHz), and USB-dedicated PLL for concurrent 54 MHz ICLK and 48 MHz USBCLK generation.
Peripheral integration includes ELC for interrupt-free inter-module triggering, DTC for efficient data transfers, and MPC for flexible pin function assignment. The device supports three low-power modes-sleep, deep sleep, and software standby-with LPT active during standby and IWDT driven by dedicated 15-kHz oscillator.
