Renesas’ RL78/L23 16-bit MCUs present section LCD management and capacitive contact sensing for responsive HMIs in sensible dwelling home equipment, client electronics, and metering programs. Operating at 32 MHz, these low-power MCUs embody 512 KB of dual-bank flash reminiscence, enabling seamless over-the-air firmware updates.
The MCUs supply an energetic present of 109 µA/MHz and a standby present as little as 0.365 µA, with a quick 1‑µs wakeup time. With a large voltage vary of 1.6 V to five.5 V, they’ll function instantly from 5‑V energy provides generally utilized in dwelling home equipment and industrial programs.
The reference mode of the built-in LCD controller reduces show energy by roughly 30% in comparison with the RL78/L1X sequence. A sleep mode sequencer (SMS) permits dynamic section updates with out CPU intervention, additional enhancing vitality effectivity.
Improvement instruments for the RL78/L23 embody the Sensible Configurator and QE for Capacitive Contact, which simplify system design and firmware setup. Renesas additionally supplies the RL78/L23 Quick Prototyping Board, suitable with the Arduino IDE, and a capacitive contact analysis system for {hardware} testing and validation.
RL78/L23 MCUs can be found now from the Renesas web site or distributors.
