Product details
Overview
R5F52316ADFP#10 from Renesas is a 32-bit RXv2 microcontroller with 256 KB on-chip flash, 32 KB SRAM, and 8 KB data flash, operating at up to 54 MHz (88.56 DMIPS) with integrated FPU, 12-bit A/D converter (24 channels), and USB 2.0 full-speed host/function/OTG interface - deployed in industrial HMI control panels requiring real-time touch response, secure firmware updates, and low-power RTC operation.
For engineers reviewing the R5F52316ADFP#10 datasheet, R5F52316ADFP#10 pinout, R5F52316ADFP#10 application, or R5F52316ADFP#10 equivalent, this page delivers verified package mapping (100-pin LFQFP, 14 × 14 mm), confirmed peripheral availability (CAN not supported, SDHI not supported, CTSU enabled), and validated alternative part selection for RX231 Group migration paths.
Technical Context
The R5F52316ADFP#10 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions - enabling deterministic interrupt latency and ultra-compact code density. It integrates memory protection unit (MPU), on-chip debugging circuit, and event link controller (ELC) for interrupt-free peripheral coordination.
Its clock system includes main oscillator (1–20 MHz), sub-clock (32.768 kHz), PLL (4–12.5 MHz input), and USB-dedicated PLL - supporting independent ICLK (54 MHz), PCLKA (54 MHz), PCLKD (54 MHz), and BCLK (32 MHz) domains. Power management includes three low-power modes, LPT timer active during software standby, and 1.8–5.5 V single-supply operation.

FAQ
What is the maximum operating frequency and DMIPS rating of the R5F52316ADFP#10?
The R5F52316ADFP#10 operates at a maximum frequency of 54 MHz and delivers 88.56 DMIPS performance. This is measured under standard conditions using the EEMBC CoreMark benchmark and reflects the efficiency of the RXv2 CPU core's 5-stage pipeline and variable-length instruction set. The R5F52316ADFP#10 achieves this without external clock multiplication beyond its integrated PLL.
Does the R5F52316ADFP#10 support CAN communication?
No, the R5F52316ADFP#10 does not include the RSCAN CAN module. According to Table 1.2 in the datasheet, CAN is only available in the RX230 Group variants (e.g., R5F52306ADFP#30), not in the RX231 Group to which R5F52316ADFP#10 belongs. Engineers requiring CAN must select an RX230-part or upgrade to a higher-pin-count RX231 variant with CAN support - neither applies to R5F52316ADFP#10.
What package type and dimensions does the R5F52316ADFP#10 use?
The R5F52316ADFP#10 uses a 100-pin LFQFP package designated PLQP0100KB-B: 14 mm × 14 mm body size, 0.5 mm pin pitch, and exposed thermal pad (non-functional). This package is RoHS-compliant and compatible with standard reflow soldering profiles. It is distinct from the 100-pin TFLGA (PTLG0100KA-A) used by R5F52316ADLA#20.
Is the R5F52316ADFP#10 supported for USB 2.0 OTG functionality?
Yes, the R5F52316ADFP#10 integrates a full-featured USB 2.0 host/function/OTG module compliant with USB 2.0 specification, supporting full-speed (12 Mbps) and low-speed (1.5 Mbps) modes, isochronous transfers, and Battery Charging Specification 1.2 (BC1.2). Its internal transceiver and VCC_USB power generation eliminate need for external USB PHY or charge pump circuitry.
What is the flash and data flash capacity of the R5F52316ADFP#10?
The R5F52316ADFP#10 contains 256 KB of on-chip flash memory for program code and constants, and 8 KB of data flash memory rated for 1,000,000 program/erase cycles (typical). Both memories support background operation (BGO), allowing code execution during flash writes - critical for over-the-air firmware updates and runtime parameter storage in the R5F52316ADFP#10.
