Renesas TS5111 precision temperature sensor for DDR5 memory modules

Renesas Electronics has announced a precision temperature sensor, the TS5111, targeting DDR5 memory modules as well as a host of other applications such as solid-state disks (SSDs), computing motherboards and communications equipment that require real-time temperature monitoring. The JEDEC-compliant temperature sensor enables memory modules and other temperature-sensitive systems to run at peak efficiency with real-time, closed-loop thermal management algorithms.

The product plays a critical role in providing high-precision system temperatures with programmable warning flags that enable systems to exercise thermal control loop mechanisms such as memory refresh rates, fan speeds and bandwidth throttling. Measuring 0.8 x 1.3 mm, the device is suitable for small form-factor systems as well as applications such as memory and storage modules where proximity sensing is critical for ongoing operation. The device supports I²C, SMBus and the I3C Basic protocol for data rates up to 12.5 MHz, as well as features like in-band interrupts, parity check and packet error checks.
