Microchip Bootloaders
Bootloaders are used to upgrade firmware on a target device without using an external programmer or debugger. Commonly used with microcontrollers (MCUs), a bootloader contains code that loads and executes an application program. Bootloaders can also perform additional tasks such as validating the code integrity and authenticity.
SAM D Videos Playlist
With Flash memory options up to 256 KB and SRAM up to 32 KB, the SAM D2x series features Arm® Cortex®-M0+-based microcontrollers (MCUs) optimized for low-power and cost-sensitive applications. They support various peripherals including ADCs, DACs and communication interfaces like UART, SPI and I2C. Notably, the SAM D2x family is pin compatible with other SAM D series MCUs, allowing for easy design upgrades and flexibility without the need for significant changes to existing PCB layouts.
