Powered by a 32-MHz Arm Cortex-M23 processor, the Renesas RAOE2 group of entry-level MCUs affords low energy consumption and an prolonged temperature vary. The units have a function set that’s optimized for cost-sensitive functions corresponding to battery-operated shopper electronics, small home equipment, industrial management methods, and constructing automation.
RAOE2 MCUs devour 2.8 mA in lively mode and 0.89 mA in sleep mode. An built-in high-speed on-chip oscillator helps quick wakeup, permitting the system to stay in software program standby mode longer—the place energy consumption drops to simply 0.25 µA. With ±1.0% precision, the oscillator additionally improves baud fee accuracy and maintains stability throughout a temperature vary of -40°C to +125°C.
The MCUs function from 1.6 V to five.5 V, eliminating the necessity for a degree shifter or regulator in 5-V methods. They provide as much as 128 KB of code flash and 16 KB of SRAM, together with built-in timers, serial communication interfaces, analog capabilities, and security options. Safety capabilities embody a novel ID, true random quantity generator (TRNG), AES libraries, and flash learn safety.
RAOE2 MCUs can be found now in a wide range of packages, together with a 5×5-mm, 32-lead QFN.
The publish MCUs lower energy to 0.25 µA in standby appeared first on EDN.
