STMicroelectronics miniaturizes digital temperature sensors to 2x2mm
June 09, 2010 // Julien Happich
STMicroelectronics launched a super-small and power-efficient temperature sensor allowing portable devices to benefit from features such as intelligent thermal protection. The STTS751 digital temperature sensor (DTS) is mounted on the circuit board to feedback accurate temperature data allowing the system to manage its temperature, for example, by activating a cooling fan or shutting down circuitry.
The new sensor is smaller than previous-generation sensors, measuring 2x2mm, and has an ultra-low 50-microA operating current, a power-saving 3-microA standby current, and a one-shot mode that makes the device suitable for battery-powered devices.
One-shot operation allows the sensor to sleep for extended periods, waking only to provide an instantaneous reading when triggered by the system. The STTS751 is accurate to within 1°C and communicates its temperature data via an industry-standard System-Management Bus (SMBus) interface. It operates at 2.25V in the -40° to +125°C range, programmable with 10 different conversion rates from 0.0625 to 32 conversions/s and four different resolutions (9-, 10-, 11- or 12-bit).
This allows the sensor to be easily designed into a wide range of consumer and professional equipment including solid-state drives, large display backlights, smart batteries, servers and routers, telecom and Internet infrastructure, and e-readers. The chip also feature interrupt and thermostat alarms. It comes in a choice of 6-pin 2x2mm UDFN-6L leadless package or a leaded SOT23-6L package.

The SoCKIT evaluation kit is Arrow's latest development tool, featuring an Altera Cyclone V SoC with a dual-core ARM Cortex-A9 MPCore processor integrated within its 28nm FPGA fabric.
Altera SoCs allow embedded system developers to differentiate their end product with customized hardware and software, and extend the product lifecycle through hardware and software updates in the field. This month, Arrow Electronics is giving away five SoCKIT evaluation kits featuring Altera’s ARM-Based SoCs, worth €249 each, together with the free entrance to one of Arrow’s SoC workshops organized throughout Europe.
And the winners are...
In our previous reader offer, Freescale Semiconductor was giving away five IMX6Q, Sabre-lite kits, worth £128.06 each.
Lucky winners include Mr. X. Salada Sole from the UK, Mrs A. Peric from Germany, Mr Z. Janosy from Hungary, Mr D. Gacina from Croatia and Mr B. Boris from France. All should be receiving their packages soon. Let's wish them some interesting findings with their projects.
