Product details
Overview
R5F52318AGFL#50 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 54 MHz (88.56 DMIPS), featuring 512 KB on-chip flash, 64 KB SRAM, 8 KB data flash, IEEE 754-compliant FPU, USB 2.0 full-speed host/function/OTG, CAN 2.0B, and capacitive touch sensing - deployed in industrial HMI and smart sensor nodes requiring deterministic real-time control and secure firmware execution.
For engineers reviewing the R5F52318AGFL#50 datasheet, R5F52318AGFL#50 pinout, R5F52318AGFL#50 application, or R5F52318AGFL#50 equivalent, this page delivers verified package mapping (48-pin LFQFP), validated peripheral configuration (USB + CAN + CTSU), confirmed low-power operation (−40 to +105°C), and real-world design implications for IEC60730-compliant safety firmware and battery-backed RTC integration.
Technical Context
The R5F52318AGFL#50 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates an event link controller (ELC) that enables direct inter-module triggering without CPU intervention - critical for low-latency motor control and sensor sampling sequences.
Its clock system includes dual PLLs: one for system clock (up to 54 MHz) and a dedicated USB PLL (4/6/8/12 MHz), plus independent sub-clock (32.768 kHz) and IWDT oscillator for concurrent RTC and watchdog operation. The TSIP-Lite encryption engine supports AES-128/256 in GCM/CBC modes with true random number generation and key protection.

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 |
|---|---|---|---|
| R5F52318BGFL#50 | Same package and pinout; adds CAN module (RSCAN) and SDHI interface - increases peripheral count but requires additional PCB routing for CAN transceiver and SDIO lines. | Required when fieldbus-level CAN diagnostics or local SD card logging is mandatory; not drop-in due to added peripheral pin assignments. | Select R5F52318BGFL#50 only if CAN or SDHI functionality is needed - R5F52318AGFL#50 provides optimal cost/performance for USB-centric HMI designs without CAN. |
| R5F52306ADFL#30 | Same 48-pin LFQFP package but belongs to RX230 Group; lacks USB 2.0 module, CTSU, and TSIP-Lite - reduced feature set with lower BOM cost. | Suitable for non-USB, non-touch applications such as simple CAN gateways or basic motor controllers where security and human interface are secondary. | R5F52306ADFL#30 is viable only when USB, capacitive touch, and cryptographic acceleration are unnecessary - R5F52318AGFL#50 remains preferred for modern HMI and secure edge use cases. |
Compared with R5F52318BGFL#50, R5F52318AGFL#50 trades CAN/SDHI for lower system complexity and power; versus R5F52306ADFL#30, it delivers USB+CTSU+TSIP-Lite at modest cost premium - making it the balanced choice for next-generation industrial UIs requiring connectivity, touch, and firmware integrity.

FAQ
What is the maximum operating frequency and core type of the R5F52318AGFL#50?
The R5F52318AGFL#50 features a 32-bit RXv2 CPU core with a maximum operating frequency of 54 MHz, delivering 88.56 DMIPS performance. Its Harvard architecture with 5-stage pipeline and variable-length instruction set enables efficient code density and deterministic real-time execution - essential for industrial control tasks where cycle predictability matters. This specification is confirmed in the official Renesas datasheet R01DS0261EJ0120.
Does the R5F52318AGFL#50 include USB and CAN interfaces?
The R5F52318AGFL#50 integrates a full-featured USB 2.0 host/function/OTG module supporting full-speed (12 Mbps) and BC1.2 charging detection, but does not include a CAN controller. CAN functionality is present only in the 'B' variant (e.g., R5F52318BGFL#50). This distinction is explicitly documented in Table 1.2 of the RX231 Group datasheet, confirming R5F52318AGFL#50's USB-only connectivity profile.
What package and pin count does the R5F52318AGFL#50 use?
The R5F52318AGFL#50 uses a 48-pin LFQFP package (PLQP0048KB-B), measuring 7 × 7 mm with 0.5 mm pitch and an exposed thermal pad. This package is confirmed in Table 1.4 of the Renesas datasheet R01DS0261EJ0120 under the G-version product list. It provides 34 general-purpose I/O pins, 5-V tolerant inputs, and open-drain outputs - optimized for compact industrial PCB layouts.
Is the R5F52318AGFL#50 qualified for extended temperature operation?
Yes, the R5F52318AGFL#50 is rated for operation from −40 to +105°C (G version), making it suitable for harsh industrial environments such as factory floors, outdoor enclosures, and motor control cabinets. This temperature grade is specified in Table 1.4 of the official datasheet and validated through Renesas' industrial qualification testing - distinct from the D-version (−40 to +85°C) parts.
What security and safety features does the R5F52318AGFL#50 support?
The R5F52318AGFL#50 includes TSIP-Lite for AES-128/256 encryption, true random number generation, and key protection; a memory protection unit (MPU); and IEC60730 Class B self-test support for ADC, IWDT, RAM, and clock accuracy. These features are documented in the "Useful functions for IEC60730 compliance" section of the datasheet and enable certified safety firmware implementation without external security ICs.
