NUVOTON NUC029FAE MCU M0 32M TSSOP20

GENERAL DESCRIPTION

The NuMicro®NUC029series 32-bit microcontroller isembedded with ARM®Cortex®-M0 core for industrial  control  and  applications  which need  rich  communication  interfacesor requirehigh performance,  highintegration,  andlowcost. 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®NUC029series includes fourpart numbers: NUC029LAN, NUC029NAN,NUC029ZAN, NUC029TANand NUC029FAE.

The NUC029LAN/NUC029NAN/NUC029ZAN/NUC029TANcan run up to 50MHz and operate at 2.5V  ~  5.5V,-40°C~ 85°C, andthe NUC029FAEcan  run  up  to  24  MHzand operate  at  2.5V~ 5.5V,-40°C~ 105°C.Therefore,the NUC029series can  afford  to  support  a  variety  of  industrial control and applications which need high CPU performance.

The NUC029LAN/NUC029NAN/NUC029ZAN/NUC029TANoffers  64K/64K/32Kbytes  flash,  4KbytesData Flash, 4Kbytesflash for  the ISP, and  4KbytesSRAM.The NUC029FAEoffers 16Kbytes flash, size configurable Data Flash(shared with program flash), 2Kbytesflash for the ISP, and 2K-bytesSRAM.

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 NUC029seriesin order to reduce  component  count,  board  space  and  system  cost.  These  useful  functions make  the NUC029 seriespowerful for a wide range of applications.

Additionally,  the  NuMicro®NUC029 series  is  equipped  with  ISP  (In-System  Programming)  and ICP  (In-Circuit  Programming)  functions, andIAP  (In-Application  Programming),  which  allow  the user to update the program memory without removing the chip from the actual end product.
