Product details
Overview
R5F52318AGNE#00 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 USB 2.0 full-speed host/function/OTG, CAN 2.0B (1 Mbps), 24-channel 12-bit A/D converter (0.83 µs conversion), dual 12-bit D/A outputs, capacitive touch sensing (24 keys), and TSIP-Lite encryption engine (AES-128/256). It targets industrial HMI and embedded control systems requiring secure, low-power, mixed-signal processing.
For engineers reviewing the R5F52318AGNE#00 datasheet, R5F52318AGNE#00 pinout, R5F52318AGNE#00 application, or R5F52318AGNE#00 equivalent, this MCU delivers deterministic real-time performance with FPU, MPU, ELC event-driven peripheral coordination, and IEC60730-compliant self-test functions - critical for safety-aware motor control, smart sensor nodes, and battery-powered human interface devices.
Technical Context
The R5F52318AGNE#00 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions, achieving 88.56 DMIPS at 54 MHz. It includes a single-precision IEEE754-compliant FPU, 32-bit multiplier, and hardware divider with two-cycle minimum latency.
Its clock system supports multiple sources: main oscillator (1–20 MHz), sub-clock (32.768 kHz), on-chip high-/low-speed oscillators, PLL (4–12.5 MHz input), and USB-dedicated PLL (4/6/8/12 MHz). System clock (ICLK) runs up to 54 MHz; peripheral clocks (PCLKA/B/D) are independently configurable up to 54 MHz, 32 MHz, or 54 MHz depending on module - enabling precise timing isolation for ADC, timers, and USB.

Does the R5F52318AGNE#00 include CAN interface functionality?
No, the R5F52318AGNE#00 does not integrate a CAN module. According to Renesas' official product table (R01DS0261EJ0120, Table 1.4), the "AG" prefix denotes the RX231 Group variant without CAN support. For CAN capability, select the R5F52318BGNE#U0, which shares the same 48-pin HWQFN package and adds one ISO11898-1-compliant CAN channel.
What package type and pin count does the R5F52318AGNE#00 use?
The R5F52318AGNE#00 uses the PWQN0048KB-A package: a 48-pin HWQFN with 7 × 7 mm body size, 0.5 mm pitch, and an exposed thermal pad. This compact, surface-mount package supports high-density PCB layouts while maintaining thermal performance for industrial ambient conditions up to +105°C.
What security features are implemented in the R5F52318AGNE#00?
The R5F52318AGNE#00 integrates TSIP-Lite - Renesas' Trusted Secure IP subsystem - supporting AES-128/256 encryption in GCM, CBC, and ECB modes, a true random number generator, and hardware key protection. It also includes a Memory Protection Unit (MPU) and IEC60730-compliant self-test functions for ADC, IWDT, and clock accuracy measurement.
Is the R5F52318AGNE#00 suitable for operation at extended temperature ranges?
Yes, the R5F52318AGNE#00 is rated for −40 to +105°C operation (G version), validated across its full voltage range (1.8–5.5 V). This makes it suitable for under-hood automotive auxiliary modules, industrial drives, and outdoor equipment where thermal resilience is critical - confirmed by Renesas' official datasheet revision 1.20.
