A 16-bit microcontroller presents low energy, quick wake-up, and show management, altering how residence and IoT units reply. See extra!
Renesas Electronics has launched the 16-bit RL78/L23 microcontroller (MCU) group, increasing its low-power RL78 sequence. Operating at 32MHz, these MCUs are designed for sensible residence units, client electronics, IoT, and metering programs, combining low energy consumption with options for display-based human-machine interfaces (HMI).
The RL78/L23 presents ultra-low energy operation, consuming 109μA/MHz throughout energetic use and simply 0.365μA in standby, with a 1μs wake-up time. Its dual-bank flash reminiscence helps firmware updates through FOTA, letting one financial institution run this system whereas the opposite receives updates, making certain uninterrupted operation in crucial purposes.
The MCUs characteristic a built-in phase LCD controller with a brand new VL4 reference mode that cuts LCD present by about 30% versus the RL78/L1X group. SMS (SNOOZE Mode Sequencer) allows dynamic LCD phase show with out CPU intervention, lowering wake-ups and saving energy. The IH timer (Timer KB40) permits exact multi-channel warmth management, appropriate for home equipment like rice cookers and induction cooktops.
These MCUs function throughout 1.6V–5.5V, permitting direct use with 5V energy provides, and combine capacitive contact, a temperature sensor, and an inside oscillator, lowering PCB dimension and element prices. The mixture of compact design, low energy, and HMI options makes RL78/L23 excellent for responsive, energy-efficient interfaces in fashionable units.
“The Renesas RL78 Household of 16-bit microcontrollers has been one of the crucial profitable merchandise since its launch greater than 10 years in the past, notably in residence home equipment,” mentioned Daryl Khoo, Vice President of Embedded Processing at Renesas. “I’m happy to announce the RL78/L23, a brand new era of RL78 microcontrollers with wealthy options, ideally fitted to sensible residence home equipment and cost-sensitive IoT options. With these units, we goal to offer 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.”
