Product details
Overview
R5F52318AGFP#50 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, SD host interface, capacitive touch sensing unit (24 keys), and TSIP-Lite encryption engine. It targets industrial HMI and connected sensor nodes requiring real-time control, secure firmware updates, and mixed-signal processing.
For engineers reviewing the R5F52318AGFP#50 datasheet, R5F52318AGFP#50 pinout, R5F52318AGFP#50 application, or R5F52318AGFP#50 equivalent, key selection considerations include its −40 to +105°C extended temperature rating, PLQP0100KB-B 100-pin LFQFP package, absence of CAN and SDHI in D-version variants, and compatibility with Renesas e2 studio and CS+ IDE toolchains.
Technical Context
The R5F52318AGFP#50 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-delivering 88.56 DMIPS at 54 MHz. It supports little-endian data arrangement and includes memory protection unit (MPU), on-chip divider (2-cycle min), and fast interrupt response.
Its clock system features independent ICLK (54 MHz), PCLKA (54 MHz for MTU2a), PCLKD (54 MHz for S12AD), and BCLK (32 MHz for external bus), with dedicated PLLs for USB (48 MHz) and IWDT (15 kHz oscillator). The ELC enables event-triggered peripheral operation without CPU intervention, enabling low-power synchronized module chaining.

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 | D-version variant: identical peripherals but rated for −40 to +85°C; same PLQP0100KB-B package and pinout | Suitable for commercial/indoor environments where extended temperature is not required | Select R5F52318ADFP#30 if ambient operating temperature remains ≤+85°C and cost optimization is prioritized |
| R5F52317AGFP#30 | 384 KB flash, 64 KB RAM, same package/temp rating; lacks SDHI and CAN modules per Table 1.2 | Targeted at cost-sensitive HMI or sensor nodes without SD card or CAN bus requirements | Choose R5F52317AGFP#30 when application firmware fits in 384 KB and SDHI/CAN are unused-reducing memory overhead and licensing costs |
Compared with R5F52318AGFP#50, the D-version R5F52318ADFP#30 offers identical functionality at lower thermal grade, while R5F52317AGFP#30 reduces flash capacity and removes SDHI/CAN-making both viable alternatives when those specific features are unnecessary for the target design.

FAQ
What is the maximum operating frequency and CPU performance of the R5F52318AGFP#50?
The R5F52318AGFP#50 operates at a maximum frequency of 54 MHz using the RXv2 32-bit CPU core, delivering 88.56 DMIPS. Its Harvard architecture with 5-stage pipeline, variable-length instructions, and on-chip FPU enable deterministic real-time execution for motor control, protocol stacks, and sensor fusion tasks within the R5F52318AGFP#50's thermal envelope.
Does the R5F52318AGFP#50 support USB device and host functionality simultaneously?
Yes, the R5F52318AGFP#50 integrates a USB 2.0 host/function/OTG module supporting full-speed (12 Mbps) and low-speed (1.5 Mbps) modes. It can operate as either host or device-and switch roles dynamically-enabling applications like USB-configurable HMI panels or field service tools that connect to PCs or peripherals using the same R5F52318AGFP#50 hardware.
What are the memory resources available on the R5F52318AGFP#50?
The R5F52318AGFP#50 includes 512 KB of on-chip flash memory (with no-wait access up to 32 MHz), 64 KB of SRAM (no-wait at 54 MHz), and 8 KB of data flash rated for 1,000,000 program/erase cycles. This memory configuration supports complex firmware, real-time buffers, and secure firmware update storage-all within the R5F52318AGFP#50's single-chip architecture.
How does the R5F52318AGFP#50 handle low-power operation in battery-powered applications?
The R5F52318AGFP#50 supports three low-power modes-sleep, deep sleep, and software standby-with the low-power timer (LPT) active during software standby. Its 1.8–5.5 V supply range, RTC operation on battery backup, and event-driven peripheral activation via ELC allow the R5F52318AGFP#50 to achieve µA-level idle current while maintaining responsiveness to external triggers or scheduled wake-ups.
Is the R5F52318AGFP#50 pin-compatible with other members of the RX231 Group?
Within the same package type (e.g., PLQP0100KB-B), the R5F52318AGFP#50 is pin-compatible with other RX231 Group 100-pin variants like R5F52318ADFP#30 and R5F52317AGFP#30. However, peripheral availability differs-R5F52318AGFP#50 includes SDHI and CAN, while R5F52317AGFP#30 omits them-so firmware and layout must verify module enablement per the specific R5F52318AGFP#50 datasheet.
