Product details
Overview
R5F52318AGFP#10 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 unit - deployed in industrial HMI and smart sensor nodes requiring real-time control and secure connectivity.
For engineers reviewing the R5F52318AGFP#10 datasheet, R5F52318AGFP#10 pinout, R5F52318AGFP#10 application, or R5F52318AGFP#10 equivalent, this page delivers verified package mapping (100-pin LFQFP, 14 × 14 mm), confirmed peripheral counts (6× TPU, 6× MTU2, 7× SCI), validated clock tree (54 MHz ICLK, 48 MHz USB clock), and precise functional boundaries (SDHI and CAN enabled; RTC supported; no security engine).
Technical Context
The R5F52318AGFP#10 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 domain control: ICLK (54 MHz for CPU), PCLKA (54 MHz for MTU2a), PCLKD (54 MHz for S12AD), and BCLK (32 MHz for external bus). The ELC enables direct event-triggered module operation without CPU intervention, supporting low-power synchronized peripheral chaining 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; same 100-pin LFQFP package | Suitable for commercial/industrial environments without extended temperature requirement | Select when ambient operating temperature remains below +85°C and cost sensitivity favors D-grade qualification |
| R5F52317AGFP#30 | 384 KB flash, 64 KB SRAM, same package and peripheral set; lacks SDHI and CAN modules | Targeted at cost-optimized HMI or sensor nodes where SD card logging or CAN networking is unnecessary | Choose when application firmware size fits within 384 KB and CAN/SDHI are unused - reduces licensing and validation scope |
Compared with R5F52318AGFP#10, the D-version alternative offers identical functionality at lower thermal grade, while the R5F52317AGFP#30 reduces flash capacity and removes SDHI/CAN - enabling design reuse with simplified qualification for non-automotive or non-data-logging use cases.

FAQ
What is the maximum operating temperature rating for the R5F52318AGFP#10?
The R5F52318AGFP#10 is rated for −40 to +105°C operation (G version), validated per Renesas specification R01DS0261EJ0120. This extended temperature range supports deployment in under-hood automotive modules, industrial drives, and outdoor equipment enclosures where ambient heat exceeds +85°C. The R5F52318AGFP#10 maintains full functionality-including 54 MHz CPU operation, ADC linearity, and USB compliance-across this full range.
Does the R5F52318AGFP#10 include a hardware encryption engine?
No, the R5F52318AGFP#10 does not include the TSIP-Lite security engine. While the RX231 Group datasheet lists TSIP-Lite as an option for certain variants (e.g., R5F52318BDLA), the R5F52318AGFP#10 specifically omits this feature - confirmed by Table 1.4 (G version product list) which shows "Not available" under Security Function. Applications requiring AES-128/256 or true random number generation must implement software-based alternatives or select a TSIP-equipped variant.
Which communication interfaces are enabled on the R5F52318AGFP#10?
The R5F52318AGFP#10 enables USB 2.0 full-speed host/function/OTG, CAN 2.0B (1 Mbps), 7× SCI (including IrDA via SCI5), 1× I2C (RIIC), 1× RSPI, 1× SSI, and 1× SDHI - all confirmed in Table 1.4 and Section 1.2 of R01DS0261EJ0120. Notably, SDHI and CAN are present (marked "Available"), distinguishing it from RX230 Group parts and lower-pin-count RX231 variants like the 48-pin R5F52318AGNE#U0.
What package type and pin count does the R5F52318AGFP#10 use?
The R5F52318AGFP#10 uses a 100-pin LFQFP package (PLQP0100KB-B), measuring 14 × 14 mm with 0.5 mm pitch and an exposed thermal pad. This matches the "GFP" suffix per Renesas part numbering convention and is explicitly listed in Table 1.4. The 100-pin count enables full peripheral access - including all 24 ADC channels, 2 DAC outputs, USB/SDHI/CAN signal routing, and 79 GPIOs - unlike 64-pin or 48-pin RX231 variants.
Is the RTC module functional on the R5F52318AGFP#10?
Yes, the R5F52318AGFP#10 includes a fully functional Realtime Clock (RTCe) module with calendar count mode, alarm/periodic interrupts, time capture on external events, and sub-clock (32.768 kHz) source - confirmed in Table 1.2 (RX231 Group, 100-pin row) and Section 1. Overview. Unlike some 64-pin RX231 variants where RTC is "Not supported", the R5F52318AGFP#10 retains RTC capability, enabling timestamping, scheduling, and battery-backed timekeeping in industrial and medical applications.
