June 4, 2012 -- Lattice Semiconductor Corp.has announced the immediate availability of four new reference designs for the low cost, low power MachXO2 family of programmable logic devices (PLDs). The new reference designs simplify and enhance the usability of the built-in I2C, SPI and user Flash memory functions in the MachXO2 device's Embedded Function Block (EFB). Five new demonstration designs and three updated application notes focused on the embedded, Flash memory-based EFB are also now available.

Since the MachXO2 family's production release, hundreds of organizations have utilized the EFB's built-in I2C, SPI and Flash memory functions to interface with microprocessors, microcontrollers, memories and other system peripherals in applications such as I/O expansion and bridging, data storage, configuration and power sequencing. Now, the new reference designs extend EFB ease-of-use with ready-to-use RTL code for the following functions, each with standard data and command interfaces:

The RTL code is fully commented and parameterized, so it can be easily edited for customized implementations.

The five new demonstration designs implement the EFB reference designs on Lattice low cost hardware development kits, including the discounted MachXO2 Pico Development Kit, in the following system configurations:

These designs, each with commented, pre-verified RTL and C code, are easily re-usable to help engineers get a head start on their own implementations.

Pricing and Availability

Lattice's entire portfolio of reference designs optimized for the MachXO2 family can be downloaded at no cost from the Lattice website at www.latticesemi.com/ip.

Promotional pricing for the MachXO2 Pico Development Kit is $29 for kits ordered via the Lattice online store and through Lattice distributors through December 31, 2012, or while promotional quantities last.

All MachXO2 PLDs are fully production qualified and have been shipping since 2011.
