1. General Description
1.1 Product Overview and Functional Description
AzureWave Technologies, Inc. introduces the IEEE 802.11ac/a/b/g/n 2X2 MU-MIMO WLAN &
Bluetooth NGFF module --- AW-CB250NF. The module is targeted to mobile devices including
Notebook, TV, Tablet and Gaming Device which need small package module, low power consumption,
multiple interfaces and OS support. By using AW-CB250NF, the customers can easily enable the Wi-Fi,
and BT embedded applications with the benefits of high design flexibility, short development cycle,
and quick time-to-market.
Compliance with the IEEE 802.11ac/a/b/g/n standard supporting 802.11ac Wave 2, the AW-CB250NF
uses Direct Sequence Spread Spectrum (DSSS), Orthogonal Frequency Division Multiplexing (OFDM),
DBPSK, DQPSK, CCK and QAM baseband modulation technologies. A high level of integration and full
implementation of the power management functions specified in the IEEE 802.11 standard minimize the
system power requirements by using AW-CB250NF. In addition to the support of WPA/WPA2 and WEP
64-bit and 128-bit encryption, the AW-CB250NF also supports the IEEE 802.11i security standard
through the implementation of Advanced Encryption Standard (AES)/Counter Mode CBC-MAC
Protocol (CCMP), Wired Equivalent Privacy (WEP) with Temporal Key Integrity Protocol (TKIP),
Advanced Encryption Standard (AES)/Cipher-Based Message Authentication Code (CMAC), and WLAN
Authentication and Privacy Infrastructure (WAPI) security mechanisms.
For the video, voice and multimedia applications the AW-CB250NF support 802.11e Quality of Service
(QoS). The device also supports 802.11h Dynamic Frequency Selection (DFS) for detecting radar
pulses when operating in the 5GHz range.
For Bluetooth operation, AW-CB250NF is Bluetooth 5.0 (supports Low Energy).
AW-CB250NF supports PCIE, USB 3.0/2.0, and high speed UART interfaces for WLAN and Bluetooth
to the host processor.
AW-CB250NF is suitable for multiple mobile processors for different applications with the support
cellular phone co-existence. AW-CB250NF module adopts Marvell’s latest highly-integrated dual-band
WLAN & Bluetooth SoC---88W8997. All the other components are implemented by all means to reach
the mechanical specification required.

2. Electrical Characteristic
1.1 Absolute Maximum Ratings

1.3 Clock Specifications
1.3.1 External Sleep Clock Timing
External Sleep Clock is necessary for two reasons:
1. Auto frequency Detection
This is where the internal logic will bin the Ref clock source to figure out what is the reference clock frequency
is. This is done so no strapping is needed for telling 88W8997 what the ref clock input is.
2. Allow low current modes for BT to enter sleep modes such as sniff modes.
The AW-CB250NF external sleep clock pin is powered from the 3.3V voltage supply.
1.4 Reset Configuration
The AW-CB250NF is reset to its default operating state under the following conditions:
Power-on reset (POR)
Software/Firmware reset
External pin for power down (PDn)

1.2 USB Interface
The USB device interface is compliant with the Universal Serial Bus Specification, Revision 2.0, April 27, 2000. A
USB host uses the USB cable bus and the USB 2.0 device interface to communicate with the chip. The main
features of the USB device interface include:
High/full speed operation (480/12 Mbps)
Suspend/host resume/device resume (remote wake-up)
Built-in DMA engine that reduces interrupt loads on the embedded processor and reduces the system bus
bandwidth requirement for serving the USB device operation
The USB 2.0 device interface is designed with 3.3V signal level pads.

1.2.1 USB 2.0 Device Interface Description
Table shows the signal mapping between the AW -CB250NF and the USB Specification, Revision 2.0.
1.2.2 USB 2.0 Device Functional Description
The device controller uses internal Scatter/Gather DMA engine to transfer the transmit packet from internal SRAM
to USB and the receive packet from USB to internal SRAM. The Device IN Endpoint DMA (DIEPDMAn) and Device
OUT Endpoint DMA (DOEPDMAn) registers are used by the DMA engine to access the base descriptor. The
application is interrupted after the programmed transfer size extracted from the descriptors is transmitted or
received. By using registers, interrupts, and special data structures, the device controller can communicate with the
device controller driver (application/software) about bus states, host request, and data transfer status. The device
controller driver also has all of the routines to respond to the device framework commands issued by a USB host,
so it controls the attachment, configuration, operation, and detachment of the device.
1.3 High-Speed UART Interface
The AW-CB250NF supports a high-speed Universal Asynchronous Receiver/Transmitter (UART) interface,
compliant to the industry standard 16550 specification. High-speed baud rates are supported to provide the
physical transport between the device and the host for exchanging Bluetooth data. Table shows the rates
supported.
The UART interface features include:
FIFO mode permanently selected for transmit and receive operations
Two pins for transmit and receive operations
Two flow control pins
Interrupt triggers for low-power, high throughput operation
The UART interface operation includes:
Upload boot code to the internal CPU (for debug purposes)

Support diagnostic tests
Support data input/output operations for peripheral devices connected through a standard UART interface

1.3.2.1 Booting from UART
When booting from the UART, the AW-CB250NF device has the following requirements:
- 14 -
1.3.2.2 UART as Test Port
Test diagnostic programs may be uploaded to the CPU through the UART interface. During execution, the
diagnostic program transmits performance and status information through the UART by performing a write to the
PBU address space designated to the UART.
