Leading EDGE COMPUTING
1. Introduction
The AmITX-AL-I is a low-profile Thin Mini-ITX embedded board supporting an Intel®Atom™ processor E3900 series, Intel®Pentium®
processor N4200, and Intel®Celeron®processor N3350 system-on-chip (SoC). The AmITX-AL-I is specifically designed for customers who
need optimized processing and graphics performance with low power consumption in a long product life solution.
The Intel® Atom™ processor, Intel® Pentium® processor, and Intel® Celeron® processor support non-ECC type DDR3L dual-channel
memory at 1600/1867 MHz to provide excellent overall performance. Integrated Intel® Gen9 LP Graphics includes features such as OpenGL
4.3, DirectX 12, OpenCL 2.0; and support for H.265/HEVC, H.264, MPEG2, VC1, VP9, MVC, JPEG/MJPEG hardware decode. Up to three
independent displays are available from DDI ports supporting HDMI/DisplayPort, optional single/dual-channel 18/24-bit LVDS, and optional
eDP.
The AmITX-AL-I supports dual stacked SODIMM sockets for up to 16 GB non-ECC type DDR3L memory, and graphics outputs include
DisplayPort, HDMI, and optional eDP and optional dual-channel 18/24-bit LVDS. I/O features include HD Audio, dual Gigabit Ethernet port,
4x USB 3.0 ports and 3x USB 2.0 ports, 6x COM ports, PCIe x1 slot, Mini PCIe slot, mSATA slot, and 2x SATA 6 Gb/s ports. A feature
connector provides 10 GPIO, SMBus, and I2C, and optional SIM card slot and microSD card slot are available. The AmITX-AL-I is equipped
with SPI AMI EFI BIOS, supporting embedded features such as hardware monitor and watchdog timer.
The Thin Mini-ITX form factor is the “premier standard for designing and assembling all-in-one PCs,” according to Intel. Measuring 170 mm
square and less than 25 mm thick, Thin Mini-ITX fulfills requirements for applications in digital signage, infotainment, medical, and industrial
automation that are running in limited-space environments. ADLINK’s thin Mini-ITX board also follows the Form, Fit, Function design
principle to offer standardized pinout locations and is compatible with the Micro-ATX and regular ATX chassis. The AmITX-AL-I provides an
easy and fast path to creating industrial computing solutions.
