EnSilica develops sureCore’s ultra-low power IoT reference platform
Semiconductor and IP provider, EnSilica, and sureCore, the low power synchronous random access memory (SRAM) IP developer, have announced that EnSilica has developed sureCore’s ultra-low power IoT reference platform targeted at the development of the next-generation of wearable consumer and medical applications.
Using its low power system on chip (SoC) design for battery powered applications, EnSilica delivered a complete, turnkey service covering complex digital and analogue/radio frequency (RF) technologies for both application specification integrated circuits (ASICs) and SoCs down to 28nm. The service extends from system architecting and design specification through development and implementation to the supply of production silicon. EnSilica also offers point services within the systems design, development and IC supply cycle. It also partners with all the major silicon foundries.
The sureCore IoT reference platform has been taped out using TSMC’s commercially available 40nm Ultra Low Power (40ULP) process technology. TSMC’s 40nm process integrates 193nm immersion lithography technology and ultra-low-k connection material to increase chip performance, while simultaneously lowering power consumption. Specifically developed for IoT and wearable applications, TSMC’s 40ULP process cuts leakage current by up to 70 per cent and lowers power consumption by up to 30 per cent, compared to the foundry’s Low Power (LP) process.
The sureCore IoT reference platform incorporates derivations of both its EverOn and PowerMiser SRAM IP product lines. By examining the fundamental limitations of conventional SRAM architecture to develop patented circuit designs, architecture techniques, and assist circuits, coupled with foundry-supplied, high density SRAM bit cells, sureCore’s SRAM IP operates at near-threshold bit cell retention voltages and delivers “significant” dynamic/static power savings. EverOn is capable of operation with supply voltages between 1.21 and 0.6V on commercially available 40ULP processes, across process corners, and across a -40 to +125 degree C temperature range. The PowerMiser SRAM family delivers more than 50 per cent dynamic power savings and approximately 20 per cent static power savings, compared to industry standard SRAMs available on commercially available 40ULP processes.
