Nuvoton has launched the newest addition to the NuMicro family, in the form of the 32-bit M051 series. The new MCU is powered by the ARM Cortex-M0 processor and delivers wide operating voltages and includes mixed-signal components and a variety of high-speed communication interfaces.
With an operating frequency of up to 50 MHz, equivalent to 45 DMIPS (45 Dhrystone MIPS), the NuMicro M051 series features a 32-bit single-cycle multiplier, NVIC (nested vectored interrupt controller) and dual-channel APB. The series offers built-in Flash memory from 8 KB to 64 KB, 4 KB SRAM and external bus interface (EBI) for external address expansion. In terms of peripherals, the M051 series equips high-speed interfaces such as two UARTs, two SPIs and one I²C. Analog peripherals include 8 channels of 12-bit SAR ADC, low voltage detector and brown out detector. Other features include four 32-bit timers, a watchdog timer and a built-in oscillator.
In terms of development tools, Nuvoton provides easy-to-use, full-featured development systems to customers to develop products using the NuMicro M051 series. Hardware tools including the NuTiny-M051, Nu-Link (ICE bridge), Nu-LB (development learning board), standalone writer and gang-programmer are provided. Besides the tools provided by Nuvoton, Keil, IAR and others also support the complete development tool chain for the Cortex-M series products.
