Product details
Overview
R5F51406BGFK#30 from Renesas is a 32-bit RXv2 core MCU operating at up to 48 MHz, featuring 256 KB flash, 64 KB SRAM, 8 KB data flash, on-chip FPU, and AES-128/256 hardware acceleration. It integrates CAN, 6-channel MTU2, 12-bit A/D (18 ch), dual 8-bit D/A, CTSU2SL capacitive touch (32 keys), RTC, and IEC60730-compliant safety functions for industrial control and smart sensor nodes.
For engineers reviewing the R5F51406BGFK#30 datasheet, R5F51406BGFK#30 pinout, R5F51406BGFK#30 application, or R5F51406BGFK#30 equivalent, this device delivers deterministic real-time performance with low-power software standby (0.25 µA), fast wake-up (6.2 µs), and secure firmware execution-critical for battery-powered HMI, motor control, and functional-safety–enabled edge devices.
Technical Context
The R5F51406BGFK#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions, achieving 204 CoreMark at 48 MHz. Its on-chip FPU complies with IEEE-754 single-precision, and the 32-bit divider completes in two clock cycles.
It supports four low-power modes-including software standby with LPT operation-and features ELC for interrupt-free peripheral chaining, DTC for five transfer modes, and MPC for flexible pin function assignment across its 64-pin LQFP package.
