Fueling mid-range FPGA innovation with Lattice Avant™ FPGAs and greater design flexibility with the Micron LPDDR4 

LPDDR and NOR for FPGAs

Built on Micron’s mature 1α (1-alpha) tech node, the Micron LPDDR4 complements Lattice Avant™ FPGA families by supporting higher-bandwidth and higher-capacity memory requirements ideal well-suited for applications across AI, automotive, communications, compute, industrial and security uses. Delivering speedy, high-bandwidth data rates (17 GB/s bandwidth in a 32-bit system) without compromising power efficiency, Micron LPDRAM provides longevity beyond 10 years for automotive and industrial markets, thanks to the 1α tech node.

Micron’s 4Gb to 128Gb Xccela and quad NOR products provide a wide temperature range (up to grade 1) and the high quality (auto quality) required for automotive and industrial applications, with higher read performance, reduced pin count, small package size and a simple interface. The 4- and 8-bit data width coupled with high performance enable the Avant FPGAs to provide instant-on boot as fast as 20 mS.

Lattice FPGAs

The Lattice Avant FPGA platform and the Lattice Avant-E, Avant-G and Avant-X FPGA families combine the platform’s power, performance and size advantages with unique features to address ever-more demanding customer applications across the network, from the edge to the cloud. Helping engineers achieve design efficiencies, improve operating costs, enhance reliability and enable size-efficient system designs, Lattice Avant provide power efficiency, advanced connectivity and optimized compute with modernized features suited for demanding AI/ML and computer vision applications.

Avant mid-range FPGAs offer LPDDR4 interfaces operating up to 2400 Mbps. The LPDDR4 interface uses a dedicated DFI (DDR PHY interface) for training, in conjunction with a flexible, high-efficiency controller that supports x16, x32 and x64 bit widths and an AXI-4 host interface. This memory IP solution seamlessly interfaces with the Lattice Propel™ system tool, which features drag-and-drop IP integration, high-productivity HW/SW (hardware or software) debug, and support of industry standard (integrated development environment) IDE when used with a processor-based system. The devices can be coupled with high-performance Xccela SPI memory-enabling instant-on boot as fast as 20 mS.

With the exceptional performance benefit and power efficiency of FPGAs, the demand for application-specific LPDDR4 solutions to support FPGA designs will likely dramatically increase in the coming years — from wider temp ranges to direct execute-in-place operation, all in small footprints to simplify system design.

In the case of industrial automation and robotics, smart factories, robotic arms and automated inspection systems rely on real-time control and data processing. These systems often operate in harsh environments with wide temperature fluctuations and require instant-on capabilities to minimize downtime. LPDDR4 memory, thanks to high bandwidth, enables fast data exchange between sensors and control units.
