The embedded-FPGAs, or Field Programmable Gate Arrays, are an important type of programmable logic device and an increasingly popular solution for today’s demanding applications. The LCMXO640E-3FT256I is a member of the Lattice Semiconductor family of embedded FPGAs, integrating over 2 million programmable logic gates, 32 TAP controllers, and 64KB of nonvolatile memory for user data. In this document, we will provide a brief overview of the application field and working principle of the LCMXO640E-3FT256I.

The LCMXO640E-3FT256I is a low-power embedded FPGA targeted for use in applications such as industrial control systems, medical electronics, consumer electronics and embedded systems. By combining a high density of programmable logic and a wide range of additional resources such as embedded SRAM and I/O interfaces, the LCMXO640E-3FT256I provides designers with a powerful embedded solution that is compact and low-power.

One of the key features of the LCMXO640E-3FT256I is its low-power design. The device utilizes a power-saving Dynamic Voltage and Frequency Scaling (DVFS) technology to reduce power consumption based on the actual utilization of FPGA resources in the system. In addition to DVFS, the LCMXO640E-3FT256I also features an advanced power-down mode and a unique Power-Interface-State-Save (PISS) feature that saves power by providing an active power management between ports in the device. To further reduce power consumption, the LCMXO640E-3FT256I also features built-in 2-port DLLs (Delay Locked Loops) in its PLLs, which ensures that all clocks remain synchronized throughout the system.

Besides its low-power solution, the LCMXO640E-3FT256I also provides rich design flexibility, allowing designers to program the logic within the device to meet their needs. The device features up to 2 million gates of programmable logic, up to 256k-bits of User Flash memory, up to 32 Direct Memory Access Controllers and up to 128-bits of distributed SRAM. Furthermore, the device also comes with standard I/O interfaces such as Ethernet, USB, CAN, UART and SPI, as well as safety and security interfaces such as an ATCC crypto engine and an AES accelerator.

In addition to its impressive package of features, the LCMXO640E-3FT256I also offers robust development environment and extensive design support tools. The device is supported by the industry-standard Lattice Diamond design tools and by a range of third-party EDA tools. This allows designers to easily and quickly create optimized designs for the device. Furthermore, the device also includes an extensive suite of debugging tools including on-chip trace, an FPGA Logic Analyzer and a Low Voltage Serial (LVS) interface for programming and debugging.

In conclusion, the LCMXO640E-3FT256I is an embedded FPGA solution that provides a rich feature set and robust design environment. Thanks to its low-power design, its flexible logic architecture and its integrated development support, the LCMXO640E-3FT256I is an ideal solution for rapidly deploying advanced embedded designs in applications such as industrial control systems, medical electronics, consumer electronics and embedded systems.
