It features USB 2.0 full-speed host/function/OTG, CAN interface (ISO 11898-1), 24-channel 12-bit A/D converter (0.83 µs conversion time), and capacitive touch sensing unit supporting up to 24 keys - deployed in industrial HMI and smart sensor edge nodes.
For engineers reviewing the R5F52317AGFL#10 datasheet, R5F52317AGFL#10 pinout, R5F52317AGFL#10 application, or R5F52317AGFL#10 equivalent, key selection considerations include its 48-pin LFQFP package (7 × 7 mm, 0.5 mm pitch), −40 to +105°C extended temperature grade (G version), SDHI absence, and CAN-only communication configuration versus higher-pin-count variants.
Technical Context
The R5F52317AGFL#10 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions, delivering 88.56 DMIPS at 54 MHz. It integrates TSIP-Lite encryption engine supporting AES-128/256 in GCM/CBC modes and a true random number generator for secure boot and firmware update.
Its peripheral set includes one CAN channel (1 Mbps), six SCI channels (asynchronous/clock-synchronous/smart card), one I²C bus interface (400 kbps), one RSPI (16 Mbps), and event link controller (ELC) enabling interrupt-free inter-module triggering - optimized for deterministic real-time control in thermally demanding environments.
