In stock NUC029FAE MCU TSSOP20 Nuvoton

The NuMicro® NUC029FAE series 32-bit microcontroller is embedded with ARM® Cortex® -M0 core for industrial control and applications which need rich communication interfaces or 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® NUC029 series includes four part numbers: NUC029LAN, NUC029ZAN, NUC029TAN and NUC029FAE.

The NUC029FAE can run up to 50 MHz and operate at 2.5V ~ 5.5V, -40℃ ~ 85℃, and the NUC029FAE can run up to 24 MHz and operate at 2.5V ~ 5.5V, -40℃ ~105℃. Therefore, the NUC029 series can afford to support a variety of industrial control and applications which need high CPU performance.

The NUC029FAE offers 64K/64K/32K bytes flash, 4 Kbytes Data Flash, 4 Kbytes flash for the ISP, and 4 Kbytes SRAM. The NUC029FAE offers 16 Kbytes flash, size configurable Data Flash (shared with program flash), 2 Kbytes flash for the ISP, and 2K- bytes SRAM.

Many system level peripheral functions, such as I/O Port, EBI (External Bus Interface), Timer, UART, SPI, I2C, PWM, ADC, WDT (Watchdog Timer), WWDT (Window Watchdog Timer), Analog Comparator and Brown-out Detector, have been incorporated into the NUC029 series in order to reduce component count, board space and system cost. These useful functions make the NUC029 series powerful for a wide range of applications.

Additionally, the NuMicro® NUC029 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.
