Product details
Overview
R5F52317AGFP#50 from Renesas is a 32-bit RXv2 microcontroller with 384 KB on-chip flash, 32 KB SRAM, and 8 KB data flash, operating at up to 54 MHz (88.56 DMIPS) with integrated FPU, 24-channel 12-bit A/D converter, two 12-bit D/A channels, USB 2.0 full-speed host/function/OTG, CAN, capacitive touch sensing unit (24 keys), and hardware encryption (TSIP-Lite AES-128/256). It targets industrial HMI, smart sensor nodes, and battery-powered control systems requiring real-time performance, secure firmware updates, and mixed-signal integration.
For engineers reviewing the R5F52317AGFP#50 datasheet, R5F52317AGFP#50 pinout, R5F52317AGFP#50 application, or R5F52317AGFP#50 equivalent, key selection considerations include its 100-pin LFQFP package (14 × 14 mm, 0.5 mm pitch), −40 to +105°C temperature grade (G version), support for USB BC1.2 charging detection, RTC with calendar mode and time capture, and ELC-driven low-power peripheral coordination without CPU wake-up.
Technical Context
The R5F52317AGFP#50 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions, delivering deterministic real-time execution at 54 MHz. Its memory subsystem includes no-wait SRAM access, flash accelerator for 32–54 MHz operation, and background operation (BGO) for 8 KB data flash programming during active code execution.
Peripherals are tightly coordinated via the Event Link Controller (ELC): 61 event sources-including MTU2a timers, SCI interrupts, and external pins-can directly trigger module operations (e.g., A/D conversion start, PWM waveform update) while the CPU remains in deep sleep mode, enabling ultra-low-power system-level responsiveness.

FAQ
What is the maximum operating frequency and DMIPS rating of the R5F52317AGFP#50?
The R5F52317AGFP#50 operates at a maximum frequency of 54 MHz and delivers 88.56 DMIPS (Dhrystone MIPS) under benchmark conditions. This performance stems from its RXv2 CPU core with 5-stage pipeline, variable-length instruction set, and on-chip FPU-enabling deterministic real-time execution for control and signal processing tasks without software floating-point overhead.
Does the R5F52317AGFP#50 support USB Battery Charging (BC) Specification 1.2?
Yes, the R5F52317AGFP#50's integrated USB 2.0 host/function module fully supports BC1.2, enabling detection of standard downstream ports (SDP), charging downstream ports (CDP), and dedicated charging ports (DCP) via D+/D− line state analysis. This allows the R5F52317AGFP#50 to intelligently manage power draw and enter appropriate charging modes in portable or field-deployable devices.
What are the memory resources available on the R5F52317AGFP#50?
The R5F52317AGFP#50 integrates 384 KB of on-chip flash memory for program code and constants, 32 KB of SRAM with no wait states at 54 MHz, and 8 KB of data flash rated for 1,000,000 program/erase cycles (typ.). The data flash supports background operation (BGO), allowing concurrent code execution and non-volatile parameter storage or firmware updates.
How does the Event Link Controller (ELC) enhance low-power operation in the R5F52317AGFP#50?
The ELC in the R5F52317AGFP#50 enables 61 peripheral event sources-including timer overflows, A/D completion flags, and external pin transitions-to directly trigger actions (e.g., A/D conversion start, PWM waveform update) without CPU intervention. This allows the CPU to remain in deep sleep mode while maintaining precise, autonomous peripheral coordination-reducing system power consumption in battery-operated or energy-constrained applications.
Is the R5F52317AGFP#50 qualified for extended temperature operation?
Yes, the R5F52317AGFP#50 is the G-grade variant, qualified for operation from −40 to +105°C.
