'''Ryzen Embedded V2748''' is a {{arch|64}} [[octa-core]] embedded [[x86]] microprocessor introduced by [[AMD]] in November [[2020]]. This processor is based on AMD's {{amd|Zen 2|Zen 2 microarchitecture|l=arch}} and uses a single monolithic die fabricated on a TSMC [[7 nm process]]. The V2748 operates at a base frequency of 2.9 GHz with a [[TDP]] of 45 W and a {{amd|Precision Boost|boost}} frequency of up to 4.25 GHz. This model supports a configurable TDP-down of 35 W and TDP-up of 54 W.

== Memory controller ==
This SoC features two memory controllers, each supporting DDR4 or LPDDR4x memory. In DDR4 mode the controllers support up to 64 GiB of 64-bit dual-channel memory, one DIMM per channel, with data rates of up to 3200 MT/s (25.6 GB/s per channel) and ECC. In LPDDR4x mode the controllers support up to 32 GiB of 32-bit quad-channel memory with data rates of up to 4266 MT/s (17.07 GB/s per channel).

== Expansions ==
The Ryzen Embedded V2748 supports up to 20 PCIe Gen 3 (8 GT/s) lanes configurable as one x8 and three x4 links, presumably also x2 and x1 links, with a maximum of 9 links total. Two x4 links can be configured as NVMe interface. Two SATA Gen 3 (6 Gb/s) ports are available and SATA Express is supported.   Eight USB ports are available. Four ports support USB 3.1 (10 Gb/s) speeds, two of these support Type-C connectors with DisplayPort Alternate Mode and Power Delivery capability. Four additional ports are USB 2.0 compliant, The following low speed interfaces are available: 1 × 4-wire or 2 × 2-wire UART, 4 × I2C, 2 × SMBus, LPC, SPI, GPIO.
