Product details
Overview
R5F52318BGNE#20 from Renesas is a 32-bit RXv2 microcontroller with 54 MHz max operating frequency, 512 KB on-chip flash memory, 64 KB SRAM, and integrated USB 2.0 full-speed host/function/OTG, CAN, capacitive touch sensing (10 channels), 12-bit A/D converter (12 channels), and TSIP-Lite encryption engine. It operates across −40 to +105°C and targets industrial HMI and connected sensor nodes requiring secure, low-power real-time control.
For engineers reviewing the R5F52318BGNE#20 datasheet, R5F52318BGNE#20 pinout, R5F52318BGNE#20 application, or R5F52318BGNE#20 equivalent, this device delivers deterministic real-time performance via its 88.56 DMIPS CPU core, hardware FPU, MPU, and event-link controller-enabling interrupt-free peripheral coordination in sleep states for battery-powered edge devices.
Technical Context
The R5F52318BGNE#20 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and ultra-compact code density. It integrates an IEEE 754-compliant 32-bit single-precision FPU, 32×32→64-bit multiplier, and 32-bit divider with two-cycle minimum execution.
Its clock system supports independent domain control: ICLK at 54 MHz for CPU/system, PCLKA at 54 MHz for MTU2a, PCLKD at 54 MHz for S12AD, and PCLKB at 32 MHz for most peripherals. The ELC enables direct event-triggered module operation without CPU intervention, including timer-A/D start triggers and port output enable control.
