The newest devices in the Cost-Optimized Portfolio, Spartan®-7 devices, fulfill the most demanding specifications with tiny form factor packaging and the greatest performance per watt in the industry. These devices have a MicroBlaze soft processor, which is based on 28nm technology and runs over 200 DMIPs with 800 Mb/s DDR3 capability. Spartan-7 devices also have  Q-grade (-40 to +125°C) on all commercial devices, an integrated ADC, and specific security features. These gadgets are perfect for embedded vision, sensor fusion, and any-to-any connection, among other uses in consumer, industrial, and automotive markets. Below is a list of some of the most well-liked Spartan-7 family devices:

Logic

A function generator that comprises a six-input Look Up Table (LUT) with two corresponding flip flops is present in both the Spartan-6 and 7 series. A slice is made up of many flip-flop structures and function generators. Each slice has sixteen flip-flops and eight function generators. There are two kinds of slices in 7 series devices: Slice_M and Slice_L.
The Spartan-6 and 7 series devices have the same Slice_M and Slice_L, however, the Spartan-6 devices also have a Slice_X. The Slice_L, which is offered in the 7 series, can readily handle functions that were implemented using a Slice_X. Devices from the 7 series may perform better after migrating to Slice_L.
