AMB2301_MA_1_1 3/17 Date: 01/2018 1 Introduction AMBER wireless provides with the AMB2301 a certified, qualified and listed Bluetooth class 2 module. It is based on LMX9830 from Texas Instruments. This module is qualified for a serial data or audio transmission. The module has an integrated PCB-antenna and can be placed into a circuit with surface mount techniques. AMB2301 comes with an integrated firmware with the complete Bluetooth Stack (Bluetooth 2.0). The Stack supports SPP, GAP, SDAP, DUN, OBEX, HSP and onter Profiles. A Point-to-Point connection and a Point-to-Multipoint (Piconet) connection are supported by the firmware. Up to seven active links (Piconet) and one SCO-link (Audio) are possible. The module can be integrated easily in a system. According to the application and the settings the AMB2301 can work as a stand-alone-slave-module e.g. as a virtual cable replacement in combination with any other commercial Bluetooth system. 1.1.1 Block diagram Figure 1 Block diagram

AMB2301_MA_1_1 6/17 Date: 01/2018 3.1 Minimum connection to run the AMB2301 In order to realize a radio transmission, the following connections of the AMB2301 have to be wired: VCC, GND Power supply RX, TX UART data RTS, CTS UART handshake; if does not need: short RTS and CTS or contact CTS at GND (without flow control it can come to overrun and lost data) OP3 High (connect to VCC) OP4, OP5 Configuration UART, see chapter 2.2.3 (open or 1KΩ pull-up) All other pins don’t need to be connected. 3.2 Default settings All parameters are stored inside the internal EEPROM. See [1] and [2]. In the Bluetooth environment, the device announces itself as a XXXXXX (Device Name), whereas XXXXXX has to be replaced by the device’s Bluetooth address. 3.3 Detailed Description 3.3.1 UART configuration with OP4, OP5 The serial interface of the AMB2301 must be configured as follows: OP4 OP5 Function Open Open UART speed read from NVS (EEPROM) Open High UART speed 9.6 kbps High Open UART speed 115.2 kbps High High UART speed 921.6 kbps Caution: Use 1KOhm pull up for OP4 and OP5 High state. While power up OP4 and OP5 are pulled down internally. Using other resistor values might lead to malfunction. 3.3.2 UART interface RX_BT, TX_BT, RTS#_BT and CTS#_BT The interface serves for communication with the AMB2301. Hardware handshake is used (RTS/CTS). If this should not be supported by the host system, RTS#_BT and CTS#_BT must be short circuit or CTS#_BT put on Low levels. This can lead however to data loss due to overrun. Therefore it is recommended to use handshake. 3.3.3 Details to the remaining connections of the AMB2301 ResetBB# Internal Pull up, low active, no external pull up recommended SCLK, SFS, SRD, STD Audio interface, if not used, pins does not attached PG6, PG7 I/O ports, if not used, pins does not attached Vcc, Gnd Power supply 3.4 Commando Interface The AMB2301 based on LMX9830 provides a simple Commando Interface. Detailed Information can be found in the IC documentation [2]. To simplify the use of this commands further a PC tool, the “Simply Blue Commander” is available.

AMB2301_MA_1_1 8/17 Date: 01/2018 4.2 Recommendation for footprint Figure 4 Footprint, all dimensions in mm
AMB2301_MA_1_1 9/17 Date: 01/2018 4.3 Design recommendation 4.3.1 Layout To achieve the maximum of range no metal (ground, strip line, components, etc..) has to be near the antenna, as shown hatched in the following figure. The antenna should have a distance of minimum 12.5mm to any ground, strip line or component. Most suitable is to place the antenna at the edge of the motherboard. Caution: The AMB2301 is not isolated on the bottom side, so even if there are normally no short circuit problems because of the solder resist, an isolation should be placed between AMB2301 and motherboard in case of any copper on the top side of the motherboard underneath the AMB2301. 4.3.2 Power supply For a reliable operation of the module, the power supply has to be provided with a slew rate over 3V per 500 microseconds. Take care of having no voltage on any pin until the power supply is turned on properly (Tip: Pay attention to remaining charges of smoothing capacitors).
AMB2301_MA_1_1 10/17 Date: 01/2018 4.4 Soldering & Reflow  The AMB2301-TR Units suits for automatic assembly reflow process.  AMB2301 are not vacuum packed and must be dried before soldering.  The temperature curve depends on the motherboard its character, like the number and conditioning of parts, etc. Please ask your manufactor.  Depending on the limit values of the components following limits are not allowed to excess o 260°C max. 10s (Crystal) The following drawing shows the example of the temperature curve of a 31cm² PCB assembled on one side. Figure 5 Example of a temperature curve Caution: Soldering profile has to be adapted corresponding to the conditions on the motherboard.
AMB2301_MA_1_1 11/17 Date: 01/2018 4.5 Warning notice Caution! ESD sensitive device. Care should be taken when handling the device in order to prevent permanent damage. MSL 4 Caution! This assembly contains moisture sensitive devices. Care should be taken when processing the device. It requires proper handling per IPC/JEDEC J-STD-033. Please be aware, that the cable of the power supply must not exceed a maximum length of 3 meters to comply with CE requirements regarding EMC. Since the module itself is not fused the voltage supply shall be fed from a limited power source according to EN 62368-1. 5 Modification from AMB2300 to AMB2301 There is no modification required regarding hardware connection or connection to the host (soft and hardware). Due to the new integrated antenna Radio Matters inside the application might be retested. No modification concerning the Bluetooth listing is required, as the AMB2301 comes under the same Declaration ID as the AMB2300. Customer Listings were supposed to link to this Declaration ID since market launch.
