1 Functional description

1.1 Overview

The EMMY-W1 series provides a complete short range transceiver solution that can easily be integrated into

automotive and industrial applications. The modules are designed for both simultaneous and independent

operation of the following technologies:

 IEEE 802.11a/b/g/n/ac payload data rates for Wi-Fi

 Dual-mode Bluetooth v4.2

 NFC

The EMMY-W1 series is a surface-mount device (SMD) component and can be used as a Wi-Fi micro-access point

supporting up to 10 clients. A coexistence feature on chip level improves parallel use of Bluetooth and Wi-Fi

communication. For highest throughput and performance, a module variant with separated Wi-Fi and Bluetooth

antenna pin is also available.

The modules include an integrated MAC/baseband processor and RF front-end components and can connect to

a host processor through SDIO 3.0 and high-speed UART interfaces. The EMMY-W1 series are offered in

automotive and professional grades (see 9.3 Ordering codes and 1.4 Block diagrams). The automotive grade

variant includes an automotive-qualified (AEC-Q100) chipset. A host driver for Linux 3.x is available free of

charge. The modules are radio type approved

for Europe (ETSI R&TTE), US (FCC CFR 47 part 15 unlicensed

modular transmitter approval) and Canada (IC RSS). Regulatory approvals for using this module in Japan, South

Korea, China, Taiwan and Australia will follow.
