NuMicro NUC230 / NUC240 series of 32-bit ARM microcontrollers
Nuvoton Technology Corporation company introduced two new series of 32-bit microcontrollers with embedded ARM® Cortex™-M0 core:
NuMicro NUC230 (CAN series) and NUC240 (Connectivity Series) designed for consumer electronics and industrial control applications.
They provide the high 72 MHz operating speed and are equipped with a rich set of peripherals. Compared to the older series
NUC230 and NUC240, NUC230 / NUC240 microcontrollers have additional CAN communication interface.
They key features are:
- ARM® Cortex™-M0 core which runs up to 72 MHz and supports 32-bit hardware multiplier
- NVIC for the 32 interrupt inputs, each with 4-levels of priority
- supports Serial Wire Debug (SWD) interface
- built-in LDO for wide operating voltage ranged from 2.5 V to 5.5 V
- In-System-Programming (ISP) and In-Application?Programming (IAP)
- 32/64/128 KB Flash for program code
- 8/16 KB SRAM
- fixed 4 KB Data Flash for the 32 KB and 64 KB systems and configurable Data Flash address and size for 128 KB system
- 8 KB Flash for ISP loader
- 9-channel PDMA
- four 32-bit timers
- Watchdog Timer
- Real Time Clock (RTC)
- 4-channel 16-bit PWM,
- up to 83 (NUC230) or 79 (NUC240) GPIOs
- 5 clock sources:
- external 4~24 MHz high-speed crystal oscillator for system operation
- external 32768 Hz crystal oscillator for RTC function and low power system operation
- internal 22,1184 MHz trimmable high-speed RC oscillator for system operation
- internal 10 kHz RC oscillator for Watchdog and Wake-up operation
