IDT Introduces Low-power, High-accuracy Temperature Sensor for Solid State Disk Drives

Integrated Device Technology, Inc. (IDT®) (NASDAQ: IDTI), the Analog and Digital Company™ delivering essential mixed-signal semiconductor solutions, today announced a new family of precision temperature sensors targeted at ultra-low-power solid state drive applications. This new family of devices minimizes power consumption and optimizes bill-of-materials (BOM) costs while maintaining compatibility with existing standards for high-volume memory modules.

The IDT TS3000GB0A0 is a low-power, high-accuracy temperature sensor for enterprise server and storage applications. It supports a 1.8 V power supply for reduced power consumption and compatibility with the existing supply voltage for SSD memory modules, eliminating the need for additional voltage regulators. The device continues the IDT tradition of industry-leading temperature accuracy by exceeding the requirements set forth by the Joint Electron Device Engineering Council (JEDEC) JC42.4 specification for Grade B temperature sensors over the temperature range of -20 °C to +125 °C. An innovative analog-to-digital converter (ADC) enables programmable resolution up to 12 bits (0.0625°C) with industry-leading conversion time of less than 100 nanoseconds irrespective of the resolution, dramatically improving the overall precision of thermal control loops across temperature.

“Enterprise SSDs can provide significant performance enhancements with lower power consumption in smaller footprints,” said John Unsworth of Gartner Research. “Demand for enterprise-grade SSDs has gained tremendous traction over the past few years. We predict unit shipments to grow by over 41 percent in the next five years while sales will more than quadruple for SSD providers during that timeframe.”*

“The SSD market is poised to grow explosively over the next decade and is an area of strategic focus for IDT,” said Mario Montana, vice president and general manager of the Enterprise Computing Division at IDT. “Our memory and SSD customers recognize IDT as a leader in high-performance and low-power system solutions. Our latest temperature sensor delivers these qualities and complements our extensive portfolio of enterprise server and storage solutions that includes PCI Express® flash controllers and switches, timing, power management, and other memory interface products.”

The IDT TS3000GB0A0 supports both SMBus and I2C interfaces for compatibility with the latest generation of flash memory and controllers. It is fully JEDEC compatible, offering customers a standards-based solution in a market where most competitive thermal sensors do not follow any standardization effort. The device integrates advanced, on-die power management to minimize power consumption during critical modes, such as when mobile or fault-tolerant enterprise systems are operating on battery power. It also features input glitch filtering and power-up voltage hysteresis to enhance fault tolerance, an important attribute for server and storage equipment.
