Product details
Overview
R5F52318AGFM#30 from Renesas is a 32-bit RXv2 microcontroller with 54 MHz max operating frequency, 512 KB on-chip flash memory, 64 KB SRAM, and integrated FPU compliant with IEEE754 single-precision floating-point standard. It supports USB 2.0 full-speed host/function/OTG, CAN 2.0B (1 Mbps), 24-channel 12-bit A/D converter (0.83 µs conversion time), and capacitive touch sensing unit for up to 24 keys - deployed in industrial HMI and smart sensor edge nodes.
For engineers reviewing the R5F52318AGFM#30 datasheet, R5F52318AGFM#30 pinout, R5F52318AGFM#30 application, or R5F52318AGFM#30 equivalent, key selection criteria include its 64-pin LFQFP package (PLQP0064KB-C), −40 to +105°C extended temperature grade, SDHI interface support, and absence of CAN module per Table 1.4 - critical for thermal-critical embedded control designs requiring USB+touch+RTC integration without external bus expansion.
Technical Context
The R5F52318AGFM#30 belongs to the RX231 Group and implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions. It integrates TSIP-Lite encryption engine supporting AES-128/256 in GCM/CBC/ECB modes, plus hardware CRC calculator with three polynomials and true random number generator.
Its clock system includes main oscillator (1–20 MHz), sub-clock (32.768 kHz), PLL (4–12.5 MHz input), USB-dedicated PLL (4/6/8/12 MHz), and CAC for frequency accuracy measurement. Real-time clock operates from sub-clock with calendar mode, alarm, and time-capture functions - all functional in the G-version's −40 to +105°C range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F52318AGFP#30 | Same RX231 Group, 100-pin LFQFP (14×14 mm), adds external bus interface and 4 more SCI channels | Required for systems needing parallel memory expansion or additional UARTs; larger footprint and higher pin count | Select when external NOR/PSRAM or multi-SCI bridging is needed - not drop-in compatible due to package and pinout mismatch |
| R5F52317AGFM#30 | Same 64-pin LFQFP package and temperature grade, but 384 KB flash, 32 KB RAM, and no SDHI interface | Suitable for cost-sensitive designs omitting SD card logging or high-resolution touch UI | Drop-in replacement only if SDHI and extra 128 KB flash are unused - identical pinout and peripheral register map |
