SPBT2632C2A
Description
The SPBT2632C2A.AT2 is an easy to use Bluetooth module, compliant with Bluetooth v3.0.
The module is the smallest form factor available which provides a complete RF platform.
The SPBT2632C2A.AT2 enables electronic devices with wireless connectivity, not requiring
any RF experience or expertise for integration into the final product. The
SPBT2632C2A.AT2 module, being a certified solution, optimizes the time to market of the
final applications.
The module is designed for maximum performance in a minimal space including fast speed
UART and 7 general purpose I/O lines, several serial interface options, and up to 560 kbps
transmission speed with SPP service active, 250 kbps with iAP1 service active.
Optimized design allows the integration of a complete working Bluetooth modem, including
antenna, in the minimum possible size; only an additional external LPO (low power
oscillator) is required to enable low power mode capability.
The SPBT2632C2A.AT2 is a surface mount PCB module that provides fully embedded,
ready to use Bluetooth wireless technology. The reprogrammable Flash memory contains
embedded firmware for serial cable replacement using the Bluetooth SPP profile.
Embedded Bluetooth AT2 command firmware is a friendly interface, which realizes a simple
control for cable replacement, enabling communication with most Bluetooth enabled
devices, provided that the devices support the SPP profile. The SPBT2632C2A.AT2,
supporting iAP1 profile, provides communication with Android, smartphone, and Apple® iOS
Bluetooth enabled devices.
An Apple authentication IC is required to exchange data with an Apple device or access an
Apple device application. The AT2 FW includes the Bluetooth SPP profile capable of
recognizing the Apple authentication chip.

SPBT2632C2A
Hardware design
The SPBT2632C2A module without AT2 command embedded FW supports UART, I2C and
GPIO hardware interfaces. Note that the usage of these interfaces is dependent upon the
firmware that is loaded into the module, and is beyond the scope of this document. The AT2
command interface uses the main UART by default.
Note:
7.1
1
All unused pins should be left floating; do not ground.
2
All GND pins must be well grounded.
3
The area around the module should be free of any ground planes, power planes, trace
routings, or metal for 6 mm from the antenna in all directions.
4
Traces should not be routed underneath the module.
Module reflow installation
The SPB2632C2A is a high temperature strength surface mount Bluetooth module supplied
on a 16-pin, 6-layer PCB. The final assembly recommended reflow profiles are indicated

The soldering phase must be executed with care: In order to avoid undesired melting
phenomenon, particular attention must be paid to the setup of the peak temperature.
The following are some suggestions for the temperature profile based on IPC/JEDEC JSTD-020C, July 2004 recommendations.

UART interface
The UART is compatible with the 16550 industry standard. Four signals are provided with
the UART interface. The TXD and RXD pins are used for data while the CTS and RTS pins
are used for flow control.

Two types of system reset circuits are detailed below.The maximum voltage that can be
supplied to the RESET pin is 2.5 V. As shown in Figure 10 and Figure 11 the RESET is
active low, in absence of a reset circuit the pin is internally pulled up and therefore inactive.

Apple iOS CP reference design
The figures below give an indicative overview of what the hardware concept looks like. A
specific MFI co-processor layout is available for licensed MFI developers from the MFI
program.
The MFI co-processor can be connected to the module through the pins 11 and 12 if the
UART flow control is not required, or through the pins 5 and 6 if the full UART is needed.
As indicated at Table 7: Pin assignment on page 13 the choice between the supported
connection is made setting a FW variable. for more details on FW setting please refer to the
UM1547.

Traceability
Traceability
Each module is univocally identified by serial number stored in a 2D data matrix laser
marked on the bottom side of the module itself.
The serial number has the following format:
WW YY D FF NNN
where
WW = week
YY = year
D = product ID family
FF = production panel coordinate identification
NNN = progressive serial number.
Each module bulk is identified by a bulk ID.
Bulk ID and module 2D data matrix are linked by a reciprocal traceability link.
The module 2D data matrix traces the lot number of any raw material used.
