Cortex M0 MCU
The Nuvoton NuMicro® M032KG8AE is part of the advanced M032 Series. This series comprises of 32-bit microcontrollers that are outfitted with an Arm® Cortex®-M0 CPU complete with a 32-bit hardware multiplier/divider. The M032KG8AE operates at a voltage range of 1.8V ~ 3.6V and features 5V I/O tolerance. It can operate at speeds of up to 48/72 MHz within a temperature range of -40℃ to +105℃.
Function and Applications:
The M032 series is designed specifically for Crystal-less USB applications requiring a 1.8V low-voltage interface. This is aptly supported by an enhanced fast 2 MSPS conversion rate 12-bit ADC, comparators, and up to 24-ch 96/144 MHz PWM control. This enables fast and accurate data conversion for voltage, current, and sensor data, as well as rapid response control for external devices. Potential applications include use in mobile LCD panel controllers, IoT sensing devices, micro printers, gaming keyboards and mice, and TWS chargers, among others.
Key features of the M032KG8AE include a core based on the Arm® Cortex®-M0 processor capable of running at speeds up to 72 MHz, 256 KB Flash memory, 64 KB SRAM, up to 16 channels 12-bit 2 MSPS ADC, and a host of communication interfaces, including 2-sets of USCI interfaces, 6-set of 7.2 MHz UART interfaces, 1-set of QSPI interface, 1-set of 24 MHz SPI /I2S interface, and 2-set of 1 MHz I2C interfaces.
Package Types, Interface, & Pin Configuration:
The M032 series offers the package of LQFP128; all pin-compatible for different part numbers, simplifying system design and parts exchange. The M032KG8AE model comes in an LQFP128 14 mm x 14 mm package.
Reliability & Lifespan:
The M032KG8AE is designed to operate under a wide temperature range of - 40℃ to + 105℃, which, along with the features of 4.4 kV EFT and 5 kV ESD HBM, testifies to its high reliability. Further aspects of reliability include RTC with Calendar and Alarm, Support IEC60730 safety specifications and up to 107 GPIO (except analog pins, Support 5V tolerant I/O).
Standards & Certifications:
The M032KG8AE is designed to meet high industrial standards, including the IEC60730 safety specifications.
Application Cases & Reference Designs:
Target applications for the M032KG8AE include the Laser Distance Meter, Air Detector/Cleaner, Mobile LCD Panel Controller, Micro Printer, and WPC Wireless Charger. For development purposes, Nuvoton provides the NuMaker evaluation boards and the Nuvoton Nu-Link debugger, with third-party IDE support (Keil MDK, IAR EWARM, Eclipse IDE with GNU GCC compilers, etc.). These can serve as reference designs and starting points for applications integrating this microcontroller.
