SAML22J

SMART ARM-based Microcontroller SAM L22G / L22J / L22N Summary DATASHEET SUMMARY Introduction Atmel® | SMART SAM L22 is a series of Ultra low-power segment LCD microcontrollers using the 32-bit ARM® Cortex®-M0+ processor, ranging from 48- to 100-pins with up to 256KB Flash and 32KB of SRAM and to drive up to 320 LCD segments. The SAM L22 devices operate at a maximum frequency of 32MHz and reach 2.46 CoreMark®/MHz. With sophisticated power management technologies the SAM L22 devices run down to 39µA/MHz (CPU running CoreMark) in active mode and down to 490nA in ultra low-power backup mode with RTC. Features Processor – ARM Cortex-M0+ CPU running at up to 32MHz Single-cycle hardware multiplier Micro Trace Buffer Memory Protection Unit (MPU) Memories – 64/128/256KB in-system self-programmable Flash – 2/4/8KB Flash Read-While-Write section – 8/16/32KB SRAM Main Memory System – Power-on reset (POR) and programmable brown-out detection (BOD) – Internal and external clock options – External Interrupt Controller (EIC) 16 external interrupts that can use any I/O-Pin One non-maskable interrupt on one I/O-Pin – Two-pin Serial Wire Debug (SWD) Low Power – Idle, Standby, Backup, and Off sleep modes – SleepWalking peripherals Atmel-42402E-SAM L22G / L22J / L22N Summary_Datasheet_Summary-07/2016 – Battery backup support – Two runtime selectable power/performance levels – Embedded Buck/LDO regulator supporting on-the-fly selection – Active mode: <50µA/MHz – Standby with fu...
