Product details
Overview
R5F52316ADNE#20 from Renesas is a 32-bit RXv2 microcontroller with 54 MHz max operating frequency, 256 KB on-chip flash memory, 32 KB SRAM, and integrated 12-bit A/D converter (24 channels), 12-bit D/A converter (2 channels), USB 2.0 full-speed host/function/OTG, CAN interface, capacitive touch sensing unit (24 keys), and hardware AES encryption (TSIP-Lite). It targets industrial HMI, smart sensors, and battery-powered control systems requiring real-time performance, low-power operation, and secure firmware.
For engineers reviewing the R5F52316ADNE#20 datasheet, R5F52316ADNE#20 pinout, R5F52316ADNE#20 application, or R5F52316ADNE#20 equivalent, key selection considerations include its 48-pin HWQFN package (7 × 7 mm, 0.5 mm pitch), −40 to +85°C temperature grade (D version), absence of SDHI and CAN in this variant, and compatibility with Renesas' RX family toolchain and e2 studio IDE.
Technical Context
The R5F52316ADNE#20 implements the RXv2 CPU core with IEEE 754-compliant 32-bit floating-point unit, 32-bit multiply-accumulate, and fast interrupt handling (167 vectors). 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 concurrent 54 MHz system clock and 48 MHz USB clock.
Peripheral integration includes ELC for event-driven module triggering without CPU intervention, DTC for efficient data transfers, and MPC for flexible pin function assignment. Power management features three low-power modes, LPT timer active during software standby, and voltage detection circuits with programmable thresholds across eight levels.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F52316ADFL#30 | Same core, memory, and peripherals but in 48-pin LFQFP (PLQP0048KB-B); larger footprint, easier hand-soldering | Preferred for prototyping or low-volume production where QFN reflow is impractical | Select when board assembly process favors exposed-pad-free packages or requires higher thermal margin |
| R5F52315ADNE#U0 | 128 KB flash, 32 KB SRAM, same 48-pin HWQFN package; lacks data flash (0 KB vs. 8 KB) | Suitable for cost-sensitive applications with smaller firmware footprints and no need for field-updatable calibration data | Choose when firmware size ≤128 KB and persistent non-volatile parameter storage is handled externally |
Compared with R5F52316ADNE#20, R5F52316ADFL#30 offers identical functionality in a more manufacturable package, while R5F52315ADNE#U0 reduces flash capacity and removes data flash-making it viable only where firmware and runtime data storage needs are strictly bounded.

The R5F52316ADNE#20 operates at a maximum frequency of 54 MHz using the RXv2 32-bit CPU core, delivering 88.56 DMIPS. Its architecture includes a 5-stage pipeline, variable-length instructions, and hardware FPU compliant with IEEE 754, enabling deterministic real-time execution for control and signal processing tasks within the R5F52316ADNE#20.
Does the R5F52316ADNE#20 support USB and CAN interfaces?
The R5F52316ADNE#20 integrates a full-speed USB 2.0 host/function/OTG module supporting 12 Mbps transfer, isochronous mode, and BC1.2 battery charging. However, per Table 1.2 in the datasheet, the 48-pin HWQFN package variant (PWQN0048KB-A) does not include the CAN module-CAN is only available in 64-pin and larger RX231 packages. This applies specifically to the R5F52316ADNE#20.
What analog peripherals are included in the R5F52316ADNE#20?
The R5F52316ADNE#20 includes a 12-bit S12ADE analog-to-digital converter with 24 input channels and 0.83 µs minimum conversion time, a 12-bit R12DAA digital-to-analog converter with two output channels (0.4–AVCC0−0.5 V range), an on-chip temperature sensor, and two comparator units (CMPBa) with window mode capability-all accessible within the R5F52316ADNE#20's 48-pin footprint.
Is the R5F52316ADNE#20 suitable for low-power applications?
Yes-the R5F52316ADNE#20 supports three low-power modes (sleep, deep sleep, software standby), a low-power timer (LPT) that runs during software standby using the sub-clock or IWDT oscillator, and voltage detection circuits with programmable thresholds. These features enable µA-level sleep current and rapid wake-up, making the R5F52316ADNE#20 appropriate for battery-operated edge devices.
What security features does the R5F52316ADNE#20 provide?
The R5F52316ADNE#20 integrates TSIP-Lite, Renesas' Trusted Secure IP engine, supporting AES-128/256 encryption in ECB, CBC, GCM, and other modes, a true random number generator, and secure key management. It also includes IEC 60730-compliant self-test functions for ADC, clock accuracy measurement, and RAM, all implemented in hardware within the R5F52316ADNE#20.
