SAML21E in SAM Microcontrollers Family
The SAML21E series is a sub-family of ultra-low-power microcontrollers from Microchip Technology, based on the 32-bit ARM Cortex-M0+ processor. These MCUs are engineered specifically for energy-sensitive applications where battery life is critical. Utilizing Microchip's proprietary picoPower technology, the SAML21E achieves industry-leading power consumption in active and sleep modes, featuring efficient power gating, multiple voltage domains, and a sophisticated Event System for CPU-independent peripheral interaction.
Variants in This Sub-Family
Variants within the SAML21E sub-family primarily differ in their integrated memory density and physical packaging. Options include Flash capacities ranging from 32KB to 256KB and SRAM allocations up to 32KB. Package types vary from compact 32-pin QFN and TQFP formats to WLCSP options, catering to space-constrained PCB layouts while maintaining consistent pin-to-pin peripheral compatibility across the specific 32-pin E-series footprint.
