M031FB0AE

Introduction

The NuMicro® M031/M032 series 32-bit microcontroller, developed by Nuvoton, is based on the Arm® Cortex®-M0 core that comes with a 32-bit hardware multiplier/divider. The specialization of this product lies in its ability to operate from 1.8 ~ 3.6 V voltage, tolerance to a 5 V I/O and its capacity to run at a maximum speed of 48/72 MHz within -40℃ ~105℃. It is designed to provide a solution for applications demanding 1.8 V low-voltage interface connection and an augmented fast 2 MSPS conversion rate 12-bit ADC, among other features.

Function & Applications

The M031 series offers support for a variety of applications that need fast and accurate data conversion for voltage, current, and sensor data – and then a rapid response control to the external device. It also integrates plenty of peripherals which include Universal Serial Control Interface (USCI) that can be flexibly set as UART/SPI/I2C. Furthermore, it offers up to 10 sets of UART, 4 sets of SPI, 4 sets of I^2C, and 1-wire UART interface for data communication between master and slave devices. It's also suitable for a broad range of applications including laser distance meter, air detector/cleaner, mobile LCD panel controller, IoT sensing device, HMI controller, etc.

Performance Parameters

The M031/M032 series assures an efficient performance by providing Flash size from 16 Kbytes to 512 Kbytes and SRAM size from 2 Kbytes to 96 Kbytes. It supports high-speed SPI with 4x32 byte FIFO & Tx / Rx PDMA function and PWM input clock source from PLL (frequency up to 96/144 MHz).

Package Types, Interface & Pin Configuration
