Product details
Overview
R5F52317BDNE#00 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 TSIP-Lite encryption engine. It operates across −40 to +85°C and targets industrial HMI, smart sensor nodes, and embedded control systems requiring real-time performance and secure firmware execution.
For engineers reviewing the R5F52317BDNE#00 datasheet, R5F52317BDNE#00 pinout, R5F52317BDNE#00 application, or R5F52317BDNE#00 equivalent, this device delivers deterministic real-time response via fast interrupt handling, hardware-accelerated floating-point and DSP instructions, ELC-driven peripheral coordination without CPU wake-up, and IEC60730-compliant self-test functions for safety-critical firmware deployment.
Technical Context
The R5F52317BDNE#00 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instruction set supporting 88.56 DMIPS at 54 MHz. It integrates a single-precision IEEE 754 FPU, 32-bit multiplier, and divider with two-cycle minimum latency.
Its peripheral subsystem includes a 6-channel MTU2 timer for complementary PWM and phase counting, 6-channel TPU for input capture/output compare, 4-channel DMAC with software/external/interrupt triggers, and ELC enabling direct event-driven inter-module operation-such as triggering A/D conversion from MTU output-while the CPU remains in deep sleep mode.
