LCMXO640E-4FN256I

LCMXO640E-4FN256I FPGAs Overview

The LCMXO640E-4FN256I is optimized to meet the requirements of applications traditionally addressed by CPLDs and low capacity FPGAs: glue logic, bus bridging, bus interfacing, power-up control, and control logic. These devices bring together the best features of CPLD and FPGA devices on a single chip.

The devices use look-up tables (LUTs) and embedded block memories traditionally associated with FPGAs for flexible and efficient logic implementation. Through non-volatile technology, the devices provide the single-chip, highsecurity, instant-on capabilities traditionally associated with CPLDs. Finally, advanced process technology and careful design will provide the high pin-to-pin performance also associated with CPLDs.

The ispLEVER design tools from Lattice allow complex designs to be efficiently implemented using the LCMXO640E-4FN256I device. Popular logic synthesis tools provide synthesis library support for MachXO. The ispLEVER tools use the synthesis tool output along with the constraints from its floor planning tools to place and route the design in the MachXO device. The ispLEVER tool extracts the timing from the routing and back-annotates it into the design for timing verification.
