Overview
R5F52316AGFL#10 from Renesas is a 32-bit RXv2 microcontroller with 54 MHz max operating frequency, 256 KB on-chip flash memory, 32 KB SRAM, and integrated 12-bit A/D converter (24 channels), 12-bit D/A converter (2 channels), USB 2.0 full-speed host/function/OTG, CAN interface, capacitive touch sensing unit (24-key support), and TSIP-Lite encryption engine. It targets industrial HMI, smart sensor nodes, and battery-powered control systems requiring real-time responsiveness, secure firmware updates, and mixed-signal integration.
For engineers reviewing the R5F52316AGFL#10 datasheet, R5F52316AGFL#10 pinout, R5F52316AGFL#10 application, or R5F52316AGFL#10 equivalent, this page delivers verified technical context, package mapping to PLQP0048KB-B (48-pin LFQFP, 7 × 7 mm, 0.5 mm pitch), confirmed peripheral channel counts, power supply range (1.8–5.5 V), and functional distinctions versus RX230/RX231 group variants.
Technical Context
The R5F52316AGFL#10 implements the RXv2 CPU core with IEEE 754-compliant 32-bit single-precision FPU, 88.56 DMIPS performance at 54 MHz, and CISC Harvard architecture with 5-stage pipeline. It supports little-endian or big-endian data arrangement and includes a memory protection unit (MPU) for runtime memory access control.
Its clock system integrates main (1–20 MHz), sub-clock (32.768 kHz), and on-chip oscillators, with PLL-based system clock up to 54 MHz and USB-dedicated PLL at 48 MHz. The ELC enables event-triggered peripheral operation without CPU intervention, and the DTC supports chain transfer for low-CPU-overhead data movement.
