SMART ARM-based Microcontrollers
SAM L22G / L22J / L22N
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.
