The 802.11a/b/g/n/ac + BT 4.2 Wireless Sip module
WM-BAC-BM-25 which is a small size module based on
mental shielding package that provides full function of

802.11a/b/g/n/ac with Bluetooth 4.2 in a tiny module via
65 pins LGA Footprint.

This multi-functionality and board to board physical
interface provides SDIO v3.0 interfaces for Wi-Fi,
UART/PCM for Bluetooth.

The small size & low profile physical design make it
easier for system design to enable high performance
wireless connectivity without space constrain. The low
power consum ption and excellent radio performance
make it the best solution for OEM customers who
require embedded 802.11a/b/g/n/ac dual-band Wi-Fi +
Bluetooth features , such as, Wireless PDA, Smart
phone, MP3, PMP, slim ty p e N o te b o o k, VoIP phone etc.

The module is based on Cypress 43455 chipset. The
Radio architecture & high integration MAC/BB chip
provide excellent sensitivity. The module is designed as
a single dual-band antenna sh a re d be tween Wi-Fi and
Bluetooth for the application of small size hand held
device.

In addition to WPA, WP A2 and TKIP, AES, CC X, WPS
is suppo r ted to provide the lates t security requireme n t
on your network.

For the software and driver development, USI provides
extensive technical document and reference software
code for the system integration under the agreem ent of
Cypress International Ltd.

Hardware evaluation kit and development utilities will be
released base on listed OS and processors to OEM
customers.

! Support explicit IEEE 802.11ac transmit

beamforming.

! Supports 20, 40, and 80 MH z channels

with optional SGI (256QAM modulation).

! Full IEEE 802.11a/b/g/n legacy

compatibility with enhanced performance.

! Lead Free design w hich supporting G reen

design requirement, RoHS C o m p lian ce ,
and halogen-free.

! Small size suitable for low volume system

integration with Low power consumption

and excellent power managem ent
performance to extend battery life.

! Easy for integration into mobile and

handheld device with flexible system
configuration and antenna design.
