Product details
Overview
R5F52318AGFP#30 from Renesas is a 32-bit RXv2 microcontroller with 54 MHz max operating frequency, 512 KB on-chip flash, 64 KB SRAM, and 8 KB data flash. It integrates a single-precision IEEE 754 FPU, 12-bit 24-channel ADC (0.83 µs conversion), dual 12-bit DACs, USB 2.0 full-speed host/function/OTG, CAN 2.0B, and capacitive touch sensing-targeting industrial HMI and embedded control systems requiring real-time performance and functional safety support.
For engineers reviewing the R5F52318AGFP#30 datasheet, R5F52318AGFP#30 pinout, R5F52318AGFP#30 application, or R5F52318AGFP#30 equivalent, this MCU delivers deterministic 88.56 DMIPS execution, IEC60730-compliant self-test features (RAM test, A/D diagnostic, clock accuracy measurement), and hardware encryption (TSIP-Lite AES-128/256) for secure firmware updates and data protection in temperature-critical environments.
Technical Context
The R5F52318AGFP#30 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and on-chip MPU-enabling deterministic interrupt latency and memory protection for safety-critical tasks. Its clock system supports independent domain control: ICLK at 54 MHz for CPU/core, PCLKA at 54 MHz for MTU2a, PCLKD at 54 MHz for S12AD, and PCLKB at 32 MHz for most peripherals.
It features dual timer subsystems: six-channel MTU2a and TPU units supporting complementary PWM, phase counting, and event-triggered A/D start; plus ELC-driven module linking without CPU intervention-critical for low-power synchronized peripheral operation during sleep modes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F52318ADFP#30 | D-version (−40 to +85°C); identical peripherals and memory, but lower temperature grade. | Suitable for indoor industrial equipment without extended thermal stress. | Select when ambient operating temperature remains below +85°C and cost optimization is prioritized over extended temp margin. |
| R5F52317AGFP#30 | 384 KB flash, same 64 KB RAM, identical package and peripheral set except reduced SDHI/CAN availability per Table 1.2. | Limited by smaller code space and missing SDHI/CAN-appropriate for simpler HMI or control tasks without mass storage or automotive bus needs. | Choose when application firmware fits within 384 KB and SDHI/CAN are not required, reducing BOM cost while retaining identical footprint and toolchain compatibility. |
Compared with R5F52318AGFP#30, the D-version alternative trades extended temperature capability for lower cost in benign environments, while the R5F52317AGFP#30 reduces flash capacity and removes SDHI/CAN-making it viable only for scaled-down implementations where those modules remain unused.
