1 / 58 page  TMP139 0.5 °C Accuracy, JEDEC DDR5 Grade B, Digital Temperature Sensor With I2C and I3C Interface 1 Features • Supports JEDEC JESD302-1 DDR5 Grade B temperature sensor • Exceeds JEDEC temperature accuracy specification: – ±0.25 °C typical – ±0.5 °C maximum (+75 °C to +95 °C) – ±0.75 °C maximum (–40 °C to +125 °C) • Operating temperature range: –40 °C to +125 °C • Low power consumption: – 4.7-µA typical average quiescent current – 0.6-µA typical standby current • I/O power supply of 1 V • Core power supply of 1.8 V • Two wire serial bus interface (I2C and I3C basic operation modes) • Up to 12.5-MHz data transfer rate in I3C basic mode • In Band Interrupt (IBI) for alerting host • Parity error check function for host writes • Packet error check function for host read and writes • 11-bit resolution: 0.25 °C (1 LSB) • Standard 6-ball DSBGA (WCSP) package with 0.5-mm pitch 2 Applications • DDR5 DIMM modules • Server • Laptops • Workstations • SSDs 3 Description The TMP139 is a high-accuracy temperature sensor with an I2C / I3C compliant digital interface supporting In Band Interrupts (IBI). Supporting the interface requirements of JEDEC JESD302-1 for Grade-B devices, the TMP139 exceeds the temperature accuracy requirements of the specification, enabling higher performance DDR5 memory modules. Available in a compact 6-ball DSBGA package, TMP139 is designed for high-speed, high-accuracy and low-power thermal monitoring applications. The TMP139 has a typical accuracy of ±0.25 °C over the entire temperature range from –40 °C to +125 °C and offers an on-chip 11-bit analog-to-digital converter (ADC) providing a temperature resolution of 0.25 °C. The TMP139 is designed to operate from a core power supply of 1.8 V and I/O power supply of 1 V, with a low typical average quiescent current of 4.7 µA when performing conversions every 125 ms.
