The R5F51116ADNE#UA supports three low-power modes: Sleep, Deep Sleep, and Software Standby. In Software Standby mode, it draws just 0.44 µA while retaining RAM and register contents, with a 4.8 µs wake-up time. RTC alarm, external interrupt, or ELC event can trigger exit - enabling ultra-low-energy operation in battery-powered applications such as wireless sensors, where the R5F51116ADNE#UA achieves multi-year runtime on coin-cell batteries.
Is the R5F51116ADNE#UA pin-compatible with other members of the RX111 Group?
Yes, the R5F51116ADNE#UA shares identical pinout and electrical characteristics with all other 48-pin HWQFN variants in the RX111 Group (e.g., R5F51115ADNE#UA, R5F51117ADNE#UA), differing only in flash/RAM capacity and temperature grade. This allows hardware reuse across product tiers - for example, designing one PCB to support multiple memory configurations, with the R5F51116ADNE#UA serving as the mid-tier option balancing cost and feature set.
