It features USB 2.0 full-speed host/function/OTG, CAN interface, 24-channel 12-bit ADC, 2-channel 12-bit DAC, capacitive touch sensing unit (CTSU), and TSIP-Lite encryption engine. It targets industrial HMI, smart sensor nodes, and USB-connected embedded control systems.
For engineers reviewing the R5F52318AGFL#10 datasheet, R5F52318AGFL#10 pinout, R5F52318AGFL#10 application, or R5F52318AGFL#10 equivalent, key selection considerations include its 48-pin LFQFP package, −40 to +105°C extended temperature grade, SDHI and CAN support status, CTSU channel count, and absence of external bus interface - all confirmed for this specific variant.
Technical Context
The R5F52318AGFL#10 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling 88.56 DMIPS at 54 MHz. It integrates a dedicated USB-dedicated PLL (4/6/8/12 MHz outputs) and system PLL supporting 54 MHz ICLK and 48 MHz USB clock.
Its peripheral set includes ELC for interrupt-free module linking, DTC for efficient data transfers, and MPU for memory protection. The device supports three low-power modes (sleep, deep sleep, software standby) with LPT active during standby and RTC operation on sub-clock (32.768 kHz) with battery backup capability.
