Product details
Overview
R5F51406AGNE#30 from Renesas is a 48-MHz 32-bit RXv2 core MCU with on-chip FPU, 256 KB flash, 64 KB SRAM, 8 KB data flash, dual 8-bit DACs, 12-bit ADC (11 external channels), capacitive touch sensing (24-key self-capacitance), CAN 2.0B, and hardware AES/RNG - designed for industrial control and smart sensor nodes operating from –40°C to +105°C.
For engineers reviewing the R5F51406AGNE#30 datasheet, R5F51406AGNE#30 pinout, R5F51406AGNE#30 application, or R5F51406AGNE#30 equivalent, key selection considerations include its HWQFN-48 package, 48 MHz max frequency, 11-channel ADC, CAN interface, and temperature-grade G specification.
Technical Context
The R5F51406AGNE#30 implements the RXv2 CPU core with IEEE-754-compliant 32-bit floating-point unit and 32×32→64-bit multiplier, enabling deterministic real-time math in motor control and sensor fusion. Its clock system integrates HOCO (48 MHz ±1%), sub-clock (32.768 kHz), PLL, and CAC for accuracy monitoring.
Peripheral integration includes ELC for interrupt-free inter-module triggering, DTC for autonomous transfers, and CTSU2SL supporting self-capacitance up to 24 keys - all operating under four low-power modes with 0.25 µA software standby current and 6.2 µs wake-up time from HOCO 32 MHz.
