GRAZ, Austria--(BUSINESS WIRE)--SensorDynamics http://www.sensordynamics.cc today launched the new automotive transceiver SD341. This high performance single-chip quad band multi channel and transceiver system is the first fail-safe, fully integrated ISM band transceiver with a universal sensor interface designed to run on very low power generated by energy harvesting.

The transceiver is controlled by an ultra low power management circuit that allows operation with microwatt power only. In a typical application the power management unit activates the on-board 8051 micro controller and other blocks that are needed for a certain task as soon as sufficient energy is detected. Typical applications are car access systems and wireless plus batteryless remote sensors, e.g. tire pressure monitoring systems.

Features

The SD341 supports all four ISM bands, i.e. 315, 433, 868 and 915 MHz, for world-wide license free FSK or ASK operation. Data rates up to 125 kbit/s are possible. The 32 kByte on-chip FLASH is sufficient for complex software. Several interfaces are implemented: up to twelve mixed signal general purpose I/O pins, a four wire- (SPI compatible) and a UART- interface. For the measurement of external sensor signals two 12 bit ADCs with 400 kHz bandwidth are available. For sensor driving purposes an 8 bit DAC is implemented. To cope with different sources of energy like solar cells, electromechanical or thermo electrical energy generators, the SD341 runs with a minimum supply voltage of only 2 V and is not limited to a certain voltage slope on power on. Furthermore it accepts large voltage variations during operation without loss of performance. More details are to be found in the attached SD341 brief data sheet.

Availability and Price

SD341samples in a 6mm x 6mm QFN40 package are available now; the 1k price is 5$. An evaluation board can also be ordered.
