nanoX-TCR
CPU
The nanoX-TCR offers three versions of the Intel
®
Atom™ E6XXT CPU—the E620T, E660T, and
E680T—operating at 600MHz, 1.3GHz, and 1.6GHz, respectively. The E6XXT integrates a high-
performance x86 Processor Core with Memory Controller and 3D Graphics Engine. This single chip is
based on 45-nm process technology and provides an open-standard PCI Express v1.0 interface, supporting
user-defined PCH, ASIC, FPGA, and off-the-shelf discrete components, ideal for deeply embedded
applications.
Graphics
The E6XXT CPU provides a 2D/3D graphics engine that performs pixel shading and vertex shading within
a single hardware accelerator, which minimizes access to memory and improves render performance.
Memory
The nanoX-TCR employs two ranks of four system DRAM memory chips, which provide up to 2GB of
extended memory, supporting aggressive power management to reduce power consumption, shallow self-
refresh and a new deep self-refresh, proactive page closing policies to close unused pages, and partial writes
through data mask pins.
