1. Introduction
Libre LS6-N22S is a complete network media module. It includes an 802.11n MAC and baseband, a
2.4 GHz 2x2 MIMI radio and FEM, a 580MHz MIPS
®
24K™ CPU core, with supporting FLASH and
DRAM memory. The module also includes all the necessary I/O and control interfaces required to
build feature rich networked media products, yet cost effective with very little additional electronic
design.
The embedded high performance CPU can process many advanced applications, such as network
media streaming, rendering, routing, security and special advanced Libre technology features. The
LS6-N22S also includes a selection of interfaces to support a variety of applications, such as I2S audio
interface, a USB port and SD port for accessing external storage, SPI and UART for data and control.
Combined with the extensive LibreSync software, this small form factor and low cost design provide
excellent Wi-Fi and processing performance for the wireless connectivity required in today CE
products.
