Atmel Corp. has introduced what it claims is the semiconductor industry’s first family of high-precision digital temperature sensors targeted at the consumer, industrial, computer and medical markets.
The Atmel devices include an integrated nonvolatile register and serial EEPROM memory offering voltage range between 1.7V and 5.5V. Atmel said current digital temperature sensors have a very limited voltage range requiring multiple sensors to be bought increasing the overall bill of materials (BOM). The temperature sensors that Atmel has introduced allows engineers to cover all the voltage requirements in various applications with one device, the company said. As a result, this will reduce the overall BOM.
Atmel said the low voltage operation of the temperature sensors reduces the overall power consumption in applications such as portable handheld consumer devices, enabling longer battery life.
Bryce Morgan, strategic marketing manager at Atmel, said in a statement that developers of industrial, consumer and medical applications are looking for ways to reduce their overall BOM and with this temperature family “developers are guaranteed a wide voltage range along with higher temperature accuracy” that will work “across all market segments.” Morgan added the sensors reduce system BOM while “increasing system reliability” and the overall power by using “just one device in this new temp sensor family.”
Atmel’s digital temperature sensor family are available now priced at $0.32 in 5,000 unit quantities.
