Entry-level MCUs within the Renesas RA0L1 group mix low present consumption with capacitive contact sensing for responsive HMIs. A 32-bit Arm Cortex-M23 core operating at 32 MHz makes them well-suited for client electronics, home equipment, industrial management, and constructing automation.
The units draw 2.9 mA in energetic mode and 0.92 mA in sleep mode. Quick wakeup lets them stay in software program standby longer, the place energy drops to simply 0.25 µA—decreasing present consumption by as much as 90% in contrast with different MCUs, based on Renesas.
The RA0L1 units goal cost-sensitive functions with as much as 64 KB of code flash, 16 KB of SRAM, and a 1.6-V to five.5-V working vary that removes the necessity for stage shifters in 5-V methods. A high-speed on-chip oscillator with ±1.0% precision ensures baud charge accuracy with out a standalone oscillator, sustaining stability from -40°C to +125°C. Built-in communications, analog, security, and safety capabilities assist reduce BOM value.
RA0L1 MCUs can be found now in a wide range of packages, together with a compact 4×4-mm, 24-pin QFN.
