The NuMicro Mini51™ series can run up to 24 MHz and operate at 2.5V ~ 5.5V, -40℃ ~ 105℃, and thus can afford to support a variety of industrial control and applications which need high CPU performance. The NuMicro Mini51™ series offers 4K/8K/16K-bytes embedded program flash, size configurable data flash (shared with program flash), 2K-byte flash for the ISP, and 2Kbyte SRAM. Many system level peripheral functions, such as I/O Port, Timer, UART, SPI, I2
C, PWM, ADC, Watchdog Timer, Analog Comparator and Brown-out Detector, have been incorporated into the NuMicro Mini51™ series in order 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, which allow the user to update the program memory without removing the chip from the actual end product.
