GENERAL DESCRIPTION

The NuMicro

M051 DN/DE series 32-bit microcontroller is embedded with ARM

Cortex

® -M0

core for industrial control and applications which need rich communication interfaces. The

NuMicro

M051

DN/DE

series

includes

the

following

part

numbers:

M052xDN/xDE,

M054xDN/xDE, M058xDN/xDE and M0516xDN/xDE.

The NuMicro

® M051 DN/DE series can run up to 50 MHz and operate at 2.5V ~ 5.5V, -40℃ ~

℃, while M05xxDE operates at -40℃ ~ 105℃, and thus can afford to support a variety of

industrial control and applications which need high CPU performance. The NuMicro

M051

DN/DE series offers 8/16/32/64 KB flash, 4 KB Data Flash, 4 KB flash for the ISP, and 4 KB

SRAM.

Many system level peripheral functions, such as I/O Port, EBI (External Bus Interface), Timer,

UART, SPI, I

2C, PWM, ADC, Watchdog Timer, Window Watchdog Timer, Analog Comparator and

Brown-out Detector, have been incorporated into The NuMicro

® M051 DN/DE series in order to

reduce component count, board space and system cost. These useful functions make The

NuMicro

® M051 DN/DE series powerful for a wide range of applications.

Additionally, the NuMicro

® M051 DN/DE series is equipped with ISP (In-System Programming)

and ICP (In-Circuit Programming) functions, and IAP (In-Application Programming), which allow

the user to update the program memory without removing the chip from the actual end product.
