Product details
Overview
R5F52316ADFL#10 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 54 MHz (88.56 DMIPS), featuring 256 KB on-chip flash, 32 KB SRAM, 8 KB data flash, 12-bit A/D converter (24 channels), 12-bit D/A converter (2 channels), capacitive touch sensing unit (6 channels), RTC, USB 2.0 full-speed host/function/OTG, CAN, and TSIP-Lite encryption. It targets industrial HMI and consumer appliance control requiring integrated analog, timing, connectivity, and security functions.
For engineers reviewing the R5F52316ADFL#10 datasheet, R5F52316ADFL#10 pinout, R5F52316ADFL#10 application, or R5F52316ADFL#10 equivalent, key selection criteria include its 48-pin LFQFP package, −40 to +85°C temperature grade, absence of SDHI and CAN modules, and presence of USB, CTSU, and TSIP-Lite in this specific variant.
Technical Context
The R5F52316ADFL#10 belongs to the RX231 Group and implements the RXv2 CPU core with IEEE 754-compliant 32-bit FPU, memory protection unit (MPU), and fast interrupt response. Its clock system supports main oscillator (1–20 MHz), sub-clock (32.768 kHz), PLL (4–12.5 MHz input), and USB-dedicated PLL for independent 48 MHz USB clock generation.
Peripheral integration includes ELC for event-driven module activation without CPU intervention, DTC for interrupt-triggered data transfers, and MPC for flexible pin function assignment. The device supports three low-power modes-sleep, deep sleep, and software standby-with LPT operating during standby and IWDT driven by a dedicated 15-kHz on-chip oscillator.

FAQ
What is the maximum operating frequency and core type of the R5F52316ADFL#10?
The R5F52316ADFL#10 operates at a maximum frequency of 54 MHz using the 32-bit RXv2 CPU core, delivering 88.56 DMIPS performance. Its architecture includes a 5-stage pipeline, variable-length instructions, on-chip FPU compliant with IEEE 754, and memory protection unit (MPU). This core enables deterministic real-time execution ideal for motor control and sensor processing tasks within the R5F52316ADFL#10's 48-pin constraint.
Does the R5F52316ADFL#10 support CAN or SD host interface?
No, the R5F52316ADFL#10 does not support CAN or SD host interface (SDHI). As confirmed in Table 1.2 of the datasheet, these modules are explicitly marked "Not supported" for the 48-pin RX231 variants including R5F52316ADFL#10. The device retains USB 2.0 full-speed host/function/OTG, SCI (4 channels), I²C, RSPI, and IrDA-but omits CAN and SDHI to optimize die size and cost for its target applications.
What is the package type and pin count of the R5F52316ADFL#10?
The R5F52316ADFL#10 uses the PLQP0048KB-B package: a 48-pin Low-profile Quad Flat Package measuring 7 mm × 7 mm with 0.5 mm lead pitch. This RoHS-compliant package includes an exposed thermal pad and supports reflow soldering. Its compact footprint aligns with space-constrained industrial and consumer designs where the R5F52316ADFL#10 delivers full USB, touch sensing, and analog capabilities without requiring larger packages.
How much flash and RAM memory does the R5F52316ADFL#10 include?
The R5F52316ADFL#10 integrates 256 KB of on-chip flash memory for program storage and 32 KB of SRAM for runtime data. It also includes 8 KB of data flash rated for 1,000,000 program/erase cycles, supporting background operation (BGO) for seamless firmware updates. These memory resources are fixed for this part number and verified in Table 1.3 of the official datasheet R01DS0261EJ0120.
Is the R5F52316ADFL#10 qualified for extended temperature operation?
The R5F52316ADFL#10 is rated for −40 to +85°C operation (D version), not the extended −40 to +105°C (G version). Its ordering code suffix "D" confirms industrial-grade temperature qualification. Designs requiring operation above +85°C must select a G-version part such as R5F52316AGFL#30, which shares the same 48-pin LFQFP package but is specified for higher ambient temperatures.
