32-bit ARM CortexTM-M23 - NuMicro® Family

NUC1262 Series

The series of NuMicro Family 32-bit microcontrollers based on the ARM Cortex-M23 core using ARMv8-M architecture. They are equipped with LED Light Strip Interface (LLSI) and many others peripherals and communication interfaces, including UART, SPI, I2C, ADC and USB 2.0 FS Device using built-in 48 MHz oscillator to support the communication with PC and Mobile accessories. They are mainly designed for industrial control, light control, and home appliance.
All Ics are RoHS compliant.

* Status: P - mass production, S - samples, UD - under development, N - not recommended for new design.
