Product details
Overview
R5F52316AGFL#30 from Renesas is a 32-bit RXv2 microcontroller operating at up to 54 MHz (88.56 DMIPS), featuring 256 KB on-chip flash, 32 KB SRAM, 8 KB data flash, single-precision FPU (IEEE 754), and integrated USB 2.0 full-speed host/function/OTG, CAN, SD host interface, and capacitive touch sensing unit - deployed in industrial HMI and smart sensor edge nodes requiring deterministic real-time control and secure firmware updates.
For engineers reviewing the R5F52316AGFL#30 datasheet, R5F52316AGFL#30 pinout, R5F52316AGFL#30 application, or R5F52316AGFL#30 equivalent, this page delivers verified specifications, package mapping to PLQP0048KB-B (48-pin LFQFP, 7 × 7 mm, 0.5 mm pitch), functional pin roles, IEC60730-compliant safety features, and validated alternative MCUs for migration or second-sourcing.
Technical Context
The R5F52316AGFL#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions - enabling 1-instruction-per-cycle execution at 54 MHz. It integrates an event link controller (ELC) that triggers peripheral operations (e.g., A/D conversion start, PWM output) without CPU intervention, supporting low-power operation during sleep modes.
Its clock system includes main (1–20 MHz), sub-clock (32.768 kHz), and dedicated on-chip oscillators for IWDT and USB PLL (4/6/8/12 MHz), allowing independent domain clocks: ICLK (54 MHz), PCLKA/B/D (up to 54/32/54 MHz), BCLK (32 MHz), and FCLK (32 MHz). The MCU supports three low-power modes (sleep, deep sleep, software standby) with LPT active in standby.
