32-bit ARM-based MCUs

2 May 2012 DSP, Micros & Memory

Nuvoton Technology has launched its new Mini51 series 32-bit microcontroller, powered by the ARM Cortex-M0 processor.

The MCU runs up to 24 MHz (21,6 DMIPS) and features a 32-bit single-cycle multiplier, NVIC (nested vectored interrupt controller), built-in Flash memory from 4 KB to 16 KB, 2 KB SRAM, size-configurable data Flash, and high-speed communication interfaces such as SPI, I²C and UART . The series also offers rich analog peripherals, including eight channels of 10-bit high-speed SAR ADC, 2-channel comparators, power on reset (POR) and brown-out detect (BOD) reset.

Additional functions include six PWM outputs with dead-zone control and centre alignment, two 32-bit timers, internal 10 kHz RC driven watchdog timer, 22,1184 MHz internal oscillator (HIRC), and dynamically calibrating the HIRC OSC to 22,0 MHz ±% from -400°C to 850°C by the external 32,768 kHz crystal oscillator (LXT).

In terms of development tools, Nuvoton provides the NuTiny-Mini51 SDK development tool and Nu-LB-Mini51 learning board, standalone writer and gang-programmer. Besides these, Keil RVMDK, IAR EWARM and CooCox – a free and open development tool – also support the complete development tool chain with project manager, editor, compiler tools and other C-SPY debugger for the Mini51 series.
