SAML21J in SAM Microcontrollers Family
The SAML21J sub-family by Microchip Technology is a series of ultra-low-power 32-bit microcontrollers based on the ARM Cortex-M0+ architecture. Designed to meet the stringent energy requirements of battery-operated devices, these MCUs feature proprietary picoPower technology. They operate at speeds up to 48MHz and provide a sophisticated power management system, including multiple sleep modes and an ultra-low-power internal voltage regulator, making them a staple for modern IoT and portable sensing applications.
Variants in This Sub-Family
| Part Number | Difference | Stock |
|---|---|---|
| ATSAML21J17B-MUT (Microchip Technology) | 256KB Flash | 6,190 |
Variants within the SAML21J sub-family primarily scale based on integrated memory density and thermal ratings. Flash memory options range from 64KB to 256KB, paired with SRAM configurations up to 40KB. While the core architecture remains consistent, specific part numbers denote different package types including TQFP and QFN. Some variants also offer specialized temperature grades for industrial environments, ensuring reliable operation across varying thermal conditions without compromising the ultra-low-power profile.
