SAML11E in SAM Microcontrollers Family
The SAML11E sub-family, manufactured by Microchip Technology, is a series of ultra-low-power microcontrollers based on the 32-bit ARM Cortex-M23 architecture. These devices integrate robust security features, including Arm TrustZone and hardware-based cryptographic acceleration, alongside advanced capacitive touch sensing capabilities. Designed for power-sensitive applications, they provide a secure foundation for Internet of Things nodes and battery-operated embedded systems that require both hardware-level isolation and high energy efficiency.
Variants in This Sub-Family
Variants within the SAML11E sub-family primarily differ in their integrated Flash memory capacity, ranging from 16KB to 64KB, and SRAM density from 8KB to 16KB. Packaging options include 32-pin TQFP, VQFN, and WLCSP formats to accommodate various PCB space constraints. While the core security features and TrustZone support remain constant across the sub-family, specific temperature grades (85C vs 105C) are available for industrial environmental requirements.
