The Microchip Technology ATSAMR21E18A-MFT is a 32-bit RISC microcontroller featuring an ARM Cortex-M0 CPU operating at up to 48MHz. This CMOS device offers 262KB of FLASH program memory and 34.688KB of on-chip data RAM. Connectivity options include I2C, LIN, SPI, UART, USART, and USB interfaces, supported by 16 I/O lines. The peripheral set includes 12 DMA channels, 6 timers, a real-time clock (RTC), watchdog timer (WDT), brown-out detector (BOD), power-on reset (POR), and two comparators. It also incorporates 4 channels of 12-bit Analog-to-Digital converters and PWM capabilities. Designed for surface mounting, this component is housed in a 32-terminal QCCN package with a 0.500mm pitch. Operating within an industrial temperature range of -40°C to 125°C, it is suitable for applications in industrial automation, consumer electronics, and IoT devices.
