Moortec Semiconductor Limited, provider of analog and mixed-signal IP solutions, announces its new High Accuracy Embedded Temperature Sensor targeting UMC’s advanced node 28nm HPC CMOS technology. This latest addition to the temperature sensor range extends Moortec’s position as the leading provider of embedded thermal sensors and on-chip monitoring IP to semiconductor customers worldwide. The new UMC 28nm HPC Embedded Temperature Sensor is a high precision low power junction temperature sensor that has been developed to be embedded into ASIC designs.
On-chip Process, Voltage and Temperature (PVT) monitoring is becoming a key consideration for 40-nanometer (nm), 28-nm and FinFET technology–based designs. Higher accuracy monitors embedded within System on Chip (SoC) designs enable a greater opportunity for dynamic performance optimization, either for lower power or higher data throughput. Sensing die temperature, detecting logic speed and monitoring voltage supply levels can be used intelligently to vary system clock frequencies and the voltage levels of supply domains. A benefit of embedded thermal monitoring in particular is to enhance device reliability and life-time by assessing the electro migration effects of hot spots within the chip.
A key aspect is that PVT data collection can be applied to each and every device, either during production or ‘in-the-field’. Moortec believe that strategies adopted by IC designers over the coming years will be heavily influenced through the analysis of such data harvested from in-chip monitors during the life time of every device.
“There is now a critical need for reliable and accurate on-chip thermal monitoring for semiconductor geometries of 28nm and below”, said Managing Director Stephen Crosher. “Embedded PVT monitoring is an emerging market and we are pleased to be supporting UMC’s customers with our innovative thermal sensing circuit technology.”
Moortec have extended their IP offering within the embedded monitoring space by providing PVT control subsystems, extra digital interfacing options (eg. AMBA APB) and Dynamic Voltage Frequency Scaling (DVFS) sub-systems.
