Overview
R5F52317ADFP#50 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 keys), and hardware AES encryption (TSIP-Lite). It operates across −40 to +85°C and targets industrial HMI and smart sensor nodes requiring real-time control, secure firmware updates, and mixed-signal interfacing.
For engineers reviewing the R5F52317ADFP#50 datasheet, R5F52317ADFP#50 pinout, R5F52317ADFP#50 application, or R5F52317ADFP#50 equivalent, this page delivers verified specifications, package mapping to PLQP0100KB-B (100-pin LFQFP, 14 × 14 mm), functional pinout, real-world use cases, and two validated alternative parts - all derived exclusively from Renesas R01DS0261EJ0120 Rev.1.20 documentation.
Technical Context
The R5F52317ADFP#50 implements the RXv2 CPU core with IEEE 754-compliant 32-bit floating-point unit, 32-bit multiply-accumulate, and fast interrupt handling (167 vectors). Its clock system supports independent domain clocks: ICLK at 54 MHz for CPU, PCLKA at 54 MHz for MTU2a, PCLKD at 54 MHz for S12AD, and PCLKB at 32 MHz for most peripherals.
It integrates ELC (Event Link Controller) for interrupt-free module triggering, DTC (Data Transfer Controller) with chain transfer, and TSIP-Lite for AES-128/256 (GCM/CBC/ECB), true random number generation, and key protection - all designed for IEC 60730 Class B compliance in safety-critical embedded systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F52318ADFP#30 | 512 KB flash, 64 KB SRAM, same package and peripheral set; adds SDHI interface | Required when local SD card logging or firmware storage is needed beyond internal flash capacity | Select R5F52318ADFP#30 if application requires >384 KB code space or SD memory support; otherwise R5F52317ADFP#50 offers optimal cost/performance balance. |
| R5F52317BDLA#20 | TFLGA 100-pin (5.5 × 5.5 mm), same memory and peripherals; no CAN or SDHI, but adds external bus interface | Suitable for space-constrained designs needing external memory expansion (e.g., frame buffer or code overlay) | Choose R5F52317BDLA#20 only when board layout demands ultra-compact footprint and external bus access is required; PLQP0100KB-B remains preferred for standard industrial layouts. |
Compared with R5F52318ADFP#30, R5F52317ADFP#50 trades 128 KB flash and SDHI for lower unit cost and identical real-time performance; versus R5F52317BDLA#20, it retains CAN and uses a larger but more manufacturable QFP package with better thermal dissipation for sustained 54 MHz operation.
