CNX Software ☛ Renesas RL78/L23 16-bit MCU features segment LCD interface, SMS for low-power HMI systems
Renesas’ RL78/L23 is a low-power 16-bit MCU with built-in segment LCD, capacitive touch, dual-bank flash for FOTA, and a wide 1.6–5.5 V operating voltage range. It targets HMI appliances, metering, and low-cost IoT products with support up to 2037. Key features include up to 512 KB dual-bank flash, 32 KB SRAM, 8 KB data flash, with ~1 µs wake-up, and SMS (Snooze Mode Sequencer) to run LCD/touch tasks without waking the CPU. It integrates a segment LCD controller with a new VL4 reference mode that cuts LCD current by ~30% compared to the RL78/L1x.

CNX Software ☛ Silicon Labs FG23L low-cost Arm Cortex-M33 SoC targets proprietary Sub-GHz IoT applications
Silicon Labs EFR32FG23L, or FG23L for short, is an ultra-low power, Sub-GHz wireless Arm Cortex-M33 SoC, which the company claims offers the best price/performance ratio for Sub-GHz IoT applications such as home and industrial automation, key fobs, and smart city sensor nodes. It’s a cost-down version of the PSA Certified Level 3 FG23 SoC equipped with less memory (32KB vs 64KB) and storage (128KB vs 512KB), less advanced security features, no segment LCD interface, and fewer GPIOs.
