'''EPYC Embedded 3351''' is a {{arch|64}} [[12-core]] [[x86]] embedded microprocessor introduced by [[AMD]] in early [[2018]] for dense servers and edge devices. This [[multi-chip package|multi-chip processor]] has CPU cores based on the {{amd|Zen|Zen microarchitecture|l=arch}} and is fabricated on a [[GlobalFoundries]] [[14 nm#GlobalFoundries|14&nbsp;nm]] process. It operates at 1.9 GHz with a {{abbr|TDP}} of 80 W and a {{amd|precision boost|turbo frequency}} of up to 3.0 GHz. This model supports a configurable TDP-down of 60 W, and up to 1 TiB of quad-channel DDR4-2666 memory.

== Expansions ==
The EPYC Embedded 3351 integrates four 8-port, 16-lane PCIe Gen 1/2/3 (8 GT/s) controllers. All lanes are configurable as x16/x8/x4/x2/x1 wide (e.g. 1x4 + 4x1 + 1x8) PCIe links, some lanes alternatively as SATA Gen 1/2/3 (6 Gb/s) or 10 Gbit/s Ethernet ports. Up to sixteen SATA ports and eight GbE ports are available on this model, as well as four USB 3.1 Gen 1 (5 Gb/s) ports, and the following low speed interfaces: {{abbr|eMMC}}, {{abbr|UART}}, {{abbr|LPC}}, {{abbr|SPI/eSPI}}, {{abbr|I<sup>2</sup>C}}, {{abbr|SMBus}}, {{abbr|GPIO}}.
