GENERAL DESCRIPTION

The NuMicro® NM1200/NM1100 series 32-bit microcontroller is embedded with ARM® Cortex® -

M0 core for industrial control and applications which require high performance, high integration,

and low cost. The Cortex® -M0 is the newest ARM® embedded processor with 32-bit performance

at a cost equivalent to the traditional 8-bit microcontroller.

The NM1200/NM1100 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

CPU 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

NM1200/NM1100 series in order to reduce component count, board space and system cost.

These useful functions make the NM1200/NM1100 series powerful for a wide range of

applications.

Additionally, the NM1200/NM1100 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. The NM1200/NM1100 series also supports In-

Application-Programming (IAP) function, user switches the code executing without the chip reset

after the embedded flash updated.
