NuMicro™ Mini51 Technical Reference Manual
1 GENERAL DESCRIPTION
The NuMicro Mini51™ series 32-bit microcontroller is embedded with an ARM® Cortex™-M0 core
for industrial controls 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 NuMicro Mini51™ series can run up to 24 MHz, and thus can afford to support a variety of
industrial controls and applications requiring high CPU performance. The NuMicro Mini51™ series
provides 4K/8K/16K-byte embedded program flash, size configurable data flash (shared with
program flash), 2K-byte flash for the ISP, and 2K-byte embedded SRAM.
A number of system-level peripheral functions, such as I/O Port, Timer, UART, SPI, I2C, PWM,
ADC, Watchdog Timer, and low voltage detector, have been incorporated in the NuMicro Mini51™
series to reduce component count, board space, and system cost. These useful functions make
the NuMicro Mini51™ series powerful for a wide range of applications.
Additionally, the NuMicro Mini51™ series is equipped with ISP (In-System Programming) and ICP
(In-Circuit Programming) functions, allowing user to update program memory without removing a
chip from an actual end product.
