Brand New 32-bit MCU Powered by the ARM Cortex-M0
Following the success of the NuMicro M051 series, Nuvoton Technology launched the brand new Mini51 series 32-bit microcontroller, powered by the ARM Cortex-M0 processor. Equipped with a variety of analog and mixed signal components and high-speed communication interfaces, the Mini51 series has been elaborated to meet customer’s need in reduced component count, board space, low power consumption, low cost, and high performance.
The Mini51 series with the ARM Cortex-M0 core 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 4KB to 16KB, 2K Bytes SRAM, size configurable Data Flash, and high-speed high-performance communication interfaces, such as SPI , I2C , and UART . The series also offers rich analog peripherals, including 8 channels of 10-bit high speed SAR ADC, 2-channel comparators, power on reset (POR), and brown-out detect (BOD) reset, etc. In addition, a number of functions also enrich the capability of the Mini51 series, including six PWM outputs with dead-zone control and center 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 ±1% from -400C to 850C by the external 32.768 kHz crystal oscillator (LXT).
In terms of development tools, Nuvoton Technology provides simple, easy-to-use and full-featured development systems for customers to develop products using the Mini51 series. With ISP, ICP, On-line/Off-line programming capability, abundant hardware tools including the NuTiny-Mini51 SDK development tool and Nu-LB-Mini51 learning board, standalone writer and gang-programmer are available to help customers shorten the time-to-market for product development and production. Besides the tools provided by Nuvoton Technology, 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.
Currently mass production of the Mini51 series has begun and all products in the series are packaged with the QFN33 (5mm×5mm), QFN33 (4mm×4mm), and LQFP48 (7mm×7mm). For PCB size consideration, the QFN33 (4mm×4mm) is the best choice. Also, there are different built-in memory options in the same package with the same pin assignment to meet the needs of different program functions.
