Product details
Overview
R5F51405AGFL#10 from Renesas is a 32-bit RXv2 core MCU operating at up to 48 MHz, featuring 128 KB flash, 32 KB SRAM, 8 KB data flash, integrated FPU, 12-bit A/D converter (11 external channels), two 8-bit D/A channels, and CAN 2.0B compliance. It targets industrial control nodes requiring deterministic real-time response, low-power operation, and IEC60730-compliant safety functions.
For engineers reviewing the R5F51405AGFL#10 datasheet, R5F51405AGFL#10 pinout, R5F51405AGFL#10 application, or R5F51405AGFL#10 equivalent, key selection criteria include its 48-MHz RXv2 CPU with 204 CoreMark score, 0.67 µs A/D conversion time, software standby current of 0.25 µA, and support for capacitive touch sensing up to 24 keys in LFQFP-48 package.
Technical Context
The R5F51405AGFL#10 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and on-chip FPU compliant with IEEE-754 single-precision. Its clock system integrates HOCO (48 MHz ±1%), sub-clock (32.768 kHz), PLL, and IWDT-dedicated 15-kHz oscillator, enabling flexible domain-specific clocking (ICLK/PCLKB/FCLK).
It supports event-driven peripheral coordination via ELC-allowing timer-triggered A/D conversion or CAN transmission without CPU wake-up-and includes module stop control, four low-power modes, and LPT operation during software standby. The device integrates IEC60730 self-test aids for A/D, RTC, IWDT, RAM, and clock accuracy measurement (CAC).
