M051 DN/DE
1
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℃ ~
85℃, 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, I2C, 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.
