How the DDR5 Temperature Sensor Works
The DDR5 Temperature Sensor device incorporates thermal sensing capability which is controlled and read over I2C and I3C Basic bus serial interface. The TS5 device operates from 1.8V nominal power supply input. The TS5 device is intended to operate up to 12.5 MHz on a 1.0V to 1.2V I3C Basic bus or up to 1 MHz on a 1.0V to 1.2V I2C bus. Â
The TS5 device is intended to interface to I2C/I3C Basic buses which have multiple devices on a shared bus and must be uniquely addressed with fixed addressing on the same bus. The TS5 device responds to specific pre-defined I2C/I3C Basic device select codes on the serial interface bus.Â

Data Center Evolution: DDR5 DIMMs Advance Server Performance
Driven by a confluence of megatrends, global data traffic is increasing at an exponential rate. For example, 5G networks are enabling billions of AI-powered IoT devices untethered from wired networks. Nowhere is the impact of all this growth being felt more intensely than in data centers. Indeed, hyperscale data centers have become the critical hubs of the global data network. DDR5 DRAM will enable the next generation of server systems providing the massive computing power of hyperscale and enterprise data centers. Learn about the benefits of DDR5 memory and the design considerations for implementing DDR5 DIMMs.
