SAML22G in SAM Microcontrollers Family
The SAML22G is a series of ultra-low-power microcontrollers developed by Microchip Technology, based on the 32-bit ARM Cortex-M0+ processor architecture. Designed specifically for energy-sensitive applications, these devices integrate an ultra-low-power segment LCD controller, sophisticated power management features, and robust security capabilities. They are engineered to maximize battery life in portable devices while providing sufficient processing power for complex human-machine interface tasks and peripheral control in modern embedded systems.
Variants in This Sub-Family
Variants within the SAML22G sub-family are primarily distinguished by their integrated Flash memory capacity, ranging from 64KB to 256KB, and SRAM density, which scales up to 32KB. While the 'G' designation signifies a 48-pin package footprint (TQFP or QFN), minor differences exist in the number of available I/O pins and specific peripheral channel counts. All variants maintain pin-to-pin compatibility within the G-series package types to simplify hardware migration.
