Description:
The SieMo S50037 is a Class2 Bluetooth Module which can be integrated into various electronic
devices to give them Bluetooth functionality.
The connections to the environment consist of a single positive power supply, a 50 Ohm Antenna
connector, UART, SPI, BCSP USB and PCM Interface, 6 PIO lines, control signals for an external
Power Amplifier and one Pin which allows to switch between two different firmware versions.
SieMo is shipped as an HCI Module, which means that the lower Bluetooth stack up to HCI is
included in the Firmware and it can be changed into a stand-alone Module with the complete BTstack and some simple applications running on the module via a firmware upgrade.
The module supports synchronous voice transmission as well as asynchronous data transfer.

The module is qualified for this temperature range. Functionality has been tested form –40 to +80°
with a small number of samples. Components are specified form –20°C to 70°C. Radio performance
decreases with rising temperature.
