For integrated circuits with really high volumes, such as MCUs, SESAME uHD (ultra High Density), the flagship product in Dolphin Integration's standard cell library offering, is paramount to decrease die costs. It stars its patented pulsed latches as Spinner Cells instead of standard D-flip flops, openly documented in 'Thorough validation: the conundrum of Pulsed latch libraries turned practical as Spinner systems', which come-up best for low-power consumption.

Using such a different technology, together with its industrialised package fully supported with scripts and manuals, users can save up to 20% silicon area on logic blocks, depending on the targeted frequency and the selected VT.

Thanks to the public Motu-Uta benchmark, the comparative evaluation of SESAME uHD with other standard cell libraries is straightforward and users can discover its benefit instantaneously.

Available from 180-40nm (foundry sponsored at TSMC 55nm LP-eFlash) and compatible both with Cadence and Synopsys EDA solutions, SESAME uHD supports Dual voltage to benefit from Low voltage and multiple threshold voltages (HVT, SVT, LVT), which enables users to take advantage of many configurations.

Evaluating SESAME uHD is a must: just request a private access to MyDolphin and benefit from all SESAME uHD results on Motu-Uta.
