Product details
Overview
R5F52315AGFL#10 from Renesas is a 32-bit RXv2 microcontroller with 54 MHz max operating frequency, 128 KB on-chip flash, 32 KB SRAM, and 8 KB data flash. It integrates a single-precision FPU (IEEE 754), 12-bit 24-channel ADC (0.83 µs conversion), dual 12-bit DACs, USB 2.0 full-speed host/function/OTG, CAN 2.0B, and capacitive touch sensing unit - deployed in industrial HMI and smart sensor nodes requiring real-time control and secure connectivity.
For engineers reviewing the R5F52315AGFL#10 datasheet, R5F52315AGFL#10 pinout, R5F52315AGFL#10 application, or R5F52315AGFL#10 equivalent, this MCU delivers deterministic real-time performance via ELC-triggered peripheral coordination, low-power operation down to software standby with LPT, and IEC60730-compliant self-test functions for safety-critical firmware updates and sensor calibration.
Technical Context
The R5F52315AGFL#10 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling 88.56 DMIPS at 54 MHz. It supports little- or big-endian data arrangement and includes an MPU for memory protection.
Clock management includes main (1–20 MHz), sub-clock (32.768 kHz), and USB-dedicated PLL (4/6/8/12 MHz), allowing independent ICLK (54 MHz), PCLKA (54 MHz), PCLKD (54 MHz), and BCLK (32 MHz) domains. The ELC enables interrupt-free inter-module triggering - e.g., MTU2a output compare events directly starting S12ADE conversions.

Does the R5F52315AGFL#10 include hardware encryption acceleration?
Yes, the R5F52315AGFL#10 integrates TSIP-Lite - a hardware security module supporting AES-128/256 in ECB, CBC, GCM, and CMAC modes, plus SHA-256 hash and a true random number generator. All cryptographic operations execute in protected memory space, and key management enforces secure storage to prevent extraction via debugger or bus snooping.
Can the R5F52315AGFL#10 operate USB and CAN simultaneously?
Yes, the R5F52315AGFL#10 supports concurrent USB 2.0 full-speed host/function/OTG and single-channel CAN 2.0B operation.

How many analog input channels does the R5F52315AGFL#10 support?
The R5F52315AGFL#10 integrates the S12ADE 12-bit A/D converter with 24 analog input channels (AD00–AD23), as confirmed in Table 1.2 of R01DS0261EJ0120. All 24 channels are available in the 48-pin PLQP0048KB-B package, with per-channel configurable sampling time and support for scan, group, and double-trigger modes.
Is the R5F52315AGFL#10 pin-compatible with other RX231 Group MCUs in the same package?
Yes, the R5F52315AGFL#10 uses the PLQP0048KB-B 48-pin LFQFP package and shares identical pinout with other RX231 Group 48-pin variants including R5F52315ADFL#30 and R5F52316AGFL#30.
