U172E
U172E is the designation used for a family of hypothetical low-power 8-bit microcontrollers developed by NovaCircuit, intended for embedded control in consumer electronics and IoT devices. The line emphasizes low cost, small form-factor packages, and energy efficiency. The core is a simplified RISC architecture compatible with standard toolchains; clock speeds range up to 32 MHz, with on-chip flash memory of 16 to 64 KB and RAM of 2 to 8 KB. Peripherals include UART, I2C, SPI, a 10-bit ADC, PWM outputs, and several timers. Integrated features such as a low-power sleep mode, brown-out detector, and common I/O multiplexing support compact designs for battery-powered devices. In packaging, U172E devices are offered in 14- and 20-pin SOIC and 28-pin QFN options, with supply voltage range from 2.0 to 3.6 V.
Variants include U172E-A, a basic version focused on cost-sensitive deployments; U172E-C, which adds a small crypto
Applications span home automation sensors, handheld meters, small appliances, and educational microcontroller kits. The U172E family
