The MachXO 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 MachXO family of non-volatile infinitely reconfigurable Programmable Logic Devices (PLDs) is designed for applications traditionally implemented using CPLDs or low-capacity FPGAs. Widely adopted in a broad range of applications that require general purpose I/O expansion, interface bridging and power-up management functions, MachXO PLDs offer the benefits of increased system integration by providing embedded memory, built-in PLLs, high performance LVDS I/O, remote field upgrade (TransFRTM technology) and a low power sleep mode, all in a single-device.
Designed for a broad range of low density applications, the MachXO PLD family is used in a variety of end markets including consumer, automotive, communications, computing, industrial and medical.

MachXO Family Selection Guide



The MachXO Mini Development Kit is an easy to use, low-cost platform to accelerate the evaluation of MachXO PLDs. The kit features the MachXO LCMXO2280 device, 2 Mbit SPI Flash and 1 Mbit SRAM memory, a temperature sensor, an expansion header for I2C and SPI interfaces, and several LEDs and user switches.

Using the preloaded mini system-on-chip (Mini SoC) design provided with the development kit, you can now test within minutes I2C, SPI, UART and SRAM interfaces in addition to the 8-bit LatticeMico8 microcontroller. You can then build your own designs using the free downloadable reference design source code, implementing these features in less than an hour. The board also features USB channels for JTAG programming and debugging from a host PC. A pin header provides access to a variety of PIO banks of the MachXO PLD and the on-board I2C bus. The board can be controlled with menu driven interface via terminal programs running on a host PC.
