SAML21G16B

SAM L21 Family Data Sheet SAM L21 Introduction Atmel® SMART SAM L21 is a series of ultra-low power microcontrollers using 32-bit Arm® Cortex®-M0+ processor at maximum 48 MHz (2.46 CoreMark®/MHz) and up to 256 KB Flash and 40 KB of SRAM in a 32-pin, 48-pin, and 64-pin packages. The sophisticated power management technologies, such as power domain gating, SleepWalking, ultra-low power peripherals allow very low-power consumptions. The highly configurable peripherals include a touch controller supporting capacitive interfaces with proximity sensing. Features Processor – Arm Cortex-M0+ CPU running at up to 48 MHz Single-cycle hardware multiplier Micro Trace Buffer Memories – 32/64/128/256-KB in-system self-programmable Flash – 1/2/4/8-KB Flash Read-While-Write section – 4/8/16/32-KB SRAM main memory – 2/4/8/8-KB SRAM low-power memory System – Power-on Reset (POR) and Brown-out Detection (BOD) – Internal and external clock options – External Interrupt Controller (EIC) – 16 external interrupts – One non-maskable interrupt – Two-pin Serial Wire Debug (SWD) programming, testing, and debugging interface Low Power – Idle, Stand-by, Backup, and Off Sleep modes – SleepWalking peripherals – Static and Dynamic Power Gating Architecture – Battery backup support – Two performance levels – Embedded Buck/LDO regulator supporting on-the-fly selection Peripherals – 16-channel Direct Memory Access Controller (DMAC) – 12-channel Event System – Up to five 16-bit Timer/Counters (TC) i...
