Temp sensors offer 1.8V SMBus and I2C Interface for the latest smartphone, tablet and PC chipsets
Microchip Technology Inc. announced a six-member family of temperature sensor ICs called the EMC118X. The family is presented as the world’s first family of temp sensors with 1.8V SMBus and I2C communications, which is required for interfacing to the latest generation of smartphone, tablet and PC chipsets. This integrated low-voltage I/O support offers reduced cost and board space because it is accomplished without an external voltage level shifter. These are also the first temp sensors, according to the company, to use an advanced sample-frequency-hopping filter, which enables temperature-monitoring traces of up to 8 inches in noisy environments with accurate readings. The EMC118X family serves a broad range of applications in the mobile, commercial and embedded computing markets, by combining the above features with options for dual, triple and quad temperature monitoring, along with hardwired system-shutdown settings that can’t be overridden by software. The sensor family employs frequency-hopping on the sampling frequency, which avoids the injection of coherent noise and enables traces of up to 8 inches while maintaining accurate temperature readings.
