The NM1100/NM1200 series can run up to 48 MHz and operate at 2.1V ~ 5.5V, -40℃ ~ 105℃, and thus can afford to support a variety of industrial control and applications which need high performance. The NM1200/NM1100 series offers 17.5K-bytes embedded program flash, size configurable Data Flash (shared with program flash), 2K-byte flash for the ISP, and 2K-byte SRAM.

Many system level peripheral functions, such as I/O Port, Timer, UART, SPI, I²C, PWM, ADC, Watchdog Timer, Analog Comparator and Brown-out Detector, have been incorporated into the NM1100/NM1200 series in order to reduce component count, board space and system cost.

Additionally, the NM1100/NM1200 series is equipped with ISP (In-System Programming) and ICP(In-Circuit Programming) functions, which allow the user to update the program memory without removing the chip from the actual end product.
