Component Details
Processor
Exynos 850 is a System-on-Chip(SoC) based on 64-bit RISC cost-effective, low-power, high-performance optimized Little
Cortex-A55 Octa micro-processor for smart phone, tablet and also embedded applications
Exynos 850 supports 64-bit code with Cortex-A55 octa-core with LPDDR4x 2-channels, provides the Mali-G52 MP1 GPU with
wide range of APIs as OpenGL ES 1.1/2/0/3.2, OpenCL 2.0 Full Profile and Vulkan 1.0/1/1. This processor supports
FHD+(1080x2520) resolution.
Exynos 850 has an integrated Image Signal Processor(ISP). Dual camera scenario supports with single 21.7mega pixel@30fps
and dual 16+5 mega pixels @30fps preview w/BDS. ISP provides zero-shutter lag of camera shooting. Sensor defect
compensation, Dynamic range compression and Geometric distortion correction can be also supported.
PMIC
There are a PMIC and two dedicated DC - DC converters for Exynos 850 platform.
S2MPU12 is a power management system chip, containing 5 buck converters , 1 high efficient boost converter and 36
LDOs(22 PMOS LDOs, 14 NMOS LDOs).
S2MPU12 supports following Audio CODEC:
• Audio performance
- 84/89 dB SNR : Stereo audio ADC output for MIC input with 20dB/0dB gain setting
- 120/120/99/97 dB SNR : DAC to Stereo Headphone/Mono line & Earpiece & Speaker
- AVC (Adaptive Volume control) for a DAC to HP path for increases dynamic range
• Audio interface
Memory (DRAM)
The WinLink E850 Development Board provides 4GB LPDDR4-SDRAM which is a 2-channel and 32bit width bus
implementation interfacing directly to the Exynos 850 build-in LPDDR controller. The DDR clock is up to 2133MHz. It is
mounted on E850 96Board.
Storage
The WinLink E850 Development Board provides an 64GB flash memory which is compliant with eMMC 5.1.
Micro SDHC
The WinLink E850 Development Board SD slot signals are routed directly to the Exynos 850’s XMMC_CARD interface. It
meets the SD3.0 standard.
Boot ROM
The WinLink E850 Development Board boots up from the eMMC.
Networking
WiFi
 Supports dual-band (2.4/5GHz) single stream 802.11 ac mode. (20/40/80MHz bandwidth)
 Highly integrated front-end eliminates external PA and LNA matching.
 Concurrent WLAN + BT reception.
 Integrated power detector to support per packet Tx power control
The WinLink E850 Development Board also has a RF connector to connect the external antenna or other RF device. If you
want to use this function, you should put the cable to CN7 connector(MS-156C2:Hirose). It will automatically switch RF input
from chip antenna(ANT1) to connected device(CN7).

Bluetooth
 Include RF transceiver, mixed ADC/DAC and baseband modem for BT5.0
 Support for BT-WLAN coexistence operation, including concurrent receive via shared LAN with WLAN.
 Support for class 1 and class 2 power-level transmissions without requiring an external PA.
HDMI
The 96Boards specification calls for an HDMI port to be present on the board. The Exynos 850 doesn’t include a built-in
HDMI interface. The WinLink E850 Development Board deploys the built-in DPI interface as the source for the HDMI output.
A peripheral Bridge IC (U9, LT8912B) performs this task and it supports a resolution from 480i to 1080p at 60Hz.
MIPI-DSI
The 96Boards specification calls for a MIPI-DSI implementation via the High Speed Expansion Connector.
The WinLink E850 Development Board implements a 4-lane MIPI_DSI interface meeting this requirement. It can support up
to FHD(1080p@60fps). The WinLink E850 Development Board routes the MIPI_DSI interface signals to the XMIPI_DSI4L
interface of the Exynos 850.
Camera Interface
The 96Boards specification calls for two camera interfaces.
The WinLink E850 Development Board supports two camera interfaces, one with a 4-lane MIPI_CSI interface and one with 2-
lane MIPI_CSI interface, meeting this requirement. The 4-lane MIPI_CSI interface can support 25M camera and the 2-lane
MIPI_CSI interface can support 8M camera.
* CN4 connector is also provided for 2-lane MIPI_CSI with I2C4 control signals.

USB Ports
The WinLink E850 Development Board supports a USB device port and three USB host ports via a USB MUX(U6).
The input channel( D+/D-) of USB MUX is connected to the P0 port of the SOC Exynos 850, and the two output
channels(1D+/1D-,2D+/2D-) are connected to micro USB port and USB hub respectively. The three USB host ports are
connected to the downstream ports of the USB hub. The control of U6(TS3USB221A) is done via a SW1’s 1st pin
(HOST_SEL). When this signal is logic low, ‘0’, the USB data lines are routed to the Micro USB connector and XEINT4 pin of

Exynos 850 is set to low, ‘0’, an external interrupt for Exynos 850 SoC as device mode. When ‘HOST_SEL’ is logic level high,
‘1’, the USB data lines are routed to U16 (a 4-port USB HUB) and the Exynos 850 is set to host mode.
USB Host ports
The WinLink E850 Development Board supports three USB host port via a USB2.0 hub (U16 LAN9514). Its upstream signal is
connected to USB_P0 interface of Exynos 850.
Port 1 of the USB HUB is routed to P2, a Type ‘A’ USB Host connector
Port 2 of the USB HUB is routed to P3, a Type ‘A’ USB Host connector
Port 3 of the USB HUB is routed to the High Speed Expansion connector.
USB Device ports
The WinLink E850 Development Board implements a device port. The port is located at J1, a Micro USB type B. It is routed to
USB_P0 interface of Exynos 850.
Note: the board can work in one mode at a time, Host mode or Device mode, not both.
Audio
The WinLink E850 Development Board has four audio ports: BT, HDMI, PCM and analog port. The analog port which
connected to PMIC(U2:S2MPU12) includes a stereo handset IO outputs.
