Introduction

The NuMicro® M031/M032 series, of which M031KG8AE is a part, are 32-bit microcontrollers based on Arm® Cortex®-M0 core. It features a wide operating voltage range between 1.8V and 3.6V, and can run up to 48/72 MHz within an ambient temperature range of -40℃ ~105℃. The M031KG8AE, specifically, operates ideally at a frequency up to 72 MHz with a 1.8V ~ 3.6V operating voltage.

Function and Applications

Developed by Nuvoton, the M031KG8AE under the M031 series provides a solution for applications that require low-voltage interface connection. It supports enhanced fast 2 MSPS conversion rate 12-bit ADC, comparators, and up-to 24-channel 144 MHz PWM control. It also features a fast and precise data conversion for voltage, current, and sensor data. Some of the targeted applications include laser distance meters, air detectors/cleaners, mobile LCD panel controllers, micro printers, gaming keyboards and mice, and IoT sensing devices.

Performance Parameters

The M031KG8AE yields high performance with its 256 KB flash memory and 64 KB SRAM, along with features like 2 MSPS ADC, 144 MHz PWM, 24 MHz SPI, and 7.2 MHz UART. It provides fast and precise data conversion of voltage, current, and sensor data, ensuring a swift response control for external devices, making it an excellent choice for industrial control and consumer applications.

Package Types, Interface and Pin Configuration

The product is packaged in a LQFP128 14 x 14 mm format and supports a variety of interfaces including UART, SPI, I2C, PDMA, and GPIO, among others. It also supports a package pin-compatible form factor for different part numbers, making system design and parts exchange quite seamless.

Reliability and Lifespan

With its wide temperature operating range (- 40 ℃ ~ + 105 ℃), the M031KG8AE guarantees a high level of reliability and durability. Additionally, its high ESD HBM (5 kV) and EFT (4.4 kV) values demonstrate resistance to electrostatic discharge and electrical fast transients, contributing even more to the product lifespan.

Standards and Certifications

The M031/M032 series, including the M031KG8AE, supports IEC60730 safety specifications for automated electrical controls for household and similar use.
