Abstract

For realizing low-cost miniaturized 2.5D/3.5D integration, this paper presents scalable embedded multi-die active bridge (S-EMAB) chips with integrated LDOs to provide on-demand I/O routing capability and in-package voltage regulation among multiple dies or chiplets. Each S-EMAB chip is a programmable bridge and implemented by an I/O array and MUX I/Os to support various transmission interfaces. The data rate of I/O array are from 50Mbps to 1Gbps, and MUX I/Os can reach to 8Gbps. Moreover, the number of programmable I/O links can be scaled up by connecting multiple S-EMAB chips in a daisy chain without extra control pins. In addition to miniaturization, LDOs are further integrated in S-EMAB chips to eliminate external LDOs. The proposed work is a fast time-to-market, low-cost, flexible, and miniaturized 3.5D integration solution for various IoT applications.
