R5F100BEANA#40 Renesas RL78/G13 16-bit Low-Power MCU 64KB Flash 32MHz QFN-32

R5F100BEANA#40 Product Overview

When selecting an MCU for general-purpose embedded applications, designers typically focus on three things: low enough power consumption, wide enough operating voltage, and sufficient peripheral integration to reduce external components. The Renesas R5F100BEANA#40 from the RL78/G13 series was built for exactly that requirement. It features a 16-bit RL78 CISC core running at up to 32MHz with 41 DMIPS performance. Its true low-power platform consumes only 66μA per MHz during operation and just 0.57μA with only RTC and LVD active. Operating from 1.6V to 5.5V, it offers 64KB code flash and 4KB data flash in a compact QFN-32-EP(5×5) package, making it ideal for industrial automation, consumer electronics, IoT edge devices, and building automation where power and space are critical.
