Renesas has introduced a brand new ultra-low-power microcontroller concentrating on human-machine interfaces in good residence gadgets: the RL78/L23.
“The Renesas RL78 household of 16-bit microcontrollers has been some of the profitable merchandise since its launch greater than 10 years in the past, notably in residence home equipment,” claimed Renesas’ vice-president of embedded processing Daryl Khoo of the household into which the brand new mannequin launches. “I am happy to announce the RL78/L23, a brand new technology of RL78 microcontrollers with wealthy options, ideally fitted to good residence home equipment and cost-sensitive IoT [Internet of Things] options. With these gadgets, we goal to supply a greater person expertise with our intuitive growth atmosphere in order that clients can get to manufacturing sooner with confidence, primarily based on market-proven Renesas applied sciences.”

The RL78/L23 has a single 16-bit RL78 microcontroller core working at as much as 32MHz, as much as 32kB of static RAM (SRAM) and 8kB of information flash plus as much as 512kB of dual-bank flash concentrating on protected over-the-air (OTA) firmware updates. Because the specs might counsel, it isn’t designed to be a velocity demon: the RL78/L23 is optimized for low-power ,with a claimed lively present draw of 109µA/MHz and a standby present of 0.365µA with a 1µs wake-up time.
Elsewhere on the chip is a section LCD controller, which is once more optimized for energy — with Rensas claiming a discount in LCD working present of round 30 per cent in comparison with the RL78/L1x household, due to an offload engine dubbed the Snooze Mode Sequencer (SMS) that may hold the LCD section show lively with out waking the CPU. There is a capacitive contact enter, an IH timer for three-channel induction warmth management, and help for working voltages of 1.6–5.5VDC and working temperatures of -40–105°C (-40–221°F).

As is custom for the corporate’s product launches, Renesas is providing a “Successful Mixture” reference design which mixes the brand new RL78/L23 with different elements from the corporate’s catalog to construct an induction-based rice cooker — utilizing the microcontroller to drive each the heating block itself and the human-machine interface.
Extra info on the RL78/L23 is offered on the Renesas web site; the corporate has additionally introduced a Quick Prototyping Board with section LCD panel, and a Capacitive Contact Analysis System.
