Cortex-M4, 84 MHz
NuMicro M4 Family
The NuMicro NUC442 and NUC472 with embedded Cortex-M4F core with DSP extensions and a Floating Point Unit runs up to 84 MHz
with 256/512 Kbytes embedded flash memories and 64K-byte embedded SRAM. It is also equipped with plenty of peripheral devices, such as Timers, Watchdog Timers,
RTC, PDMA, EBI, UART, Smart Card interface, SD HOST, SPI, I2C, I2S, PWM Timer, GPIO, LIN, CAN, PS/2, 12-bit ADC, analog comparator, operational amplifier,
temperature sensor, Low Voltage Reset Controller and Brown-out Detector. The NUC442 also provides USB 2.0 full-speed Device/Host/OTG, USB 2.0 HS device and
security functions such as tamper detection, symmetric cryptographic accelerator and secure Hash function accelerator.
NUC472 also provides Ethernet 10/100 MAC with MII and RMII interface.
