Overview
R5F51406BDFL#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, AES-128/256 hardware accelerator, and capacitive touch sensing unit supporting up to 24 keys - deployed in industrial HMI and smart sensor nodes requiring secure, low-power real-time control.
For engineers reviewing the R5F51406BDFL#30 datasheet, R5F51406BDFL#30 pinout, R5F51406BDFL#30 application, or R5F51406BDFL#30 equivalent, key selection criteria include its 48-pin LFQFP (7 × 7 mm, 0.5 mm pitch) package, 1.8–5.5 V single-supply operation, IEC60730-compliant self-test features, and integrated CAN, RSPI, and dual SCI interfaces for deterministic communication in resource-constrained embedded systems.
Technical Context
The R5F51406BDFL#30 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and ultra-compact code density. It integrates an IEEE-754-compliant 32-bit FPU, 32-bit multiplier, and on-chip divider completing division in two clock cycles - enabling high-precision math in motor control and sensor fusion without external coprocessors.
Its low-power design includes four operational modes (sleep, deep sleep, software standby, snooze), with 0.25 µA typical supply current in software standby and 6.2 µs wake-up time from that mode using the 32 MHz HOCO clock - optimized for battery-powered edge devices requiring rapid responsiveness and extended runtime.
