1.0 INTRODUCTION
The MachXO2 family of ultra-low power, instant-on, non-volatile PLDs has six devices with densities ranging
from 256 to 6864 Look-Up Tables (LUTs). In addition to LUT-based, low-cost programmable logic these devices
feature Embedded Block RAM (EBR), Distributed RAM, User Flash Memory (UFM), Phase Locked Loops
(PLLs), pre-engineered source synchronous I/O support, advanced configuration support including dual-boot
capability and hardened versions of commonly used functions such as SPI controller, I2C controller and
timer/counter. These features allow these devices to be used in low cost, high volume consumer and system
applications.
The MachXO2 devices are designed on a 65nm non-volatile low power process. The device architecture has
several features such as programmable low swing differential I/Os and the ability to turn off I/O banks, on-chip
PLLs and oscillators dynamically. These features help manage static and dynamic power consumption resulting
in low static power for all members of the family.
The MachXO2 devices are available in three options – ultra low power (ZE) and high performance (HC and HE)
devices. The ultra-low power devices are offered in three speed grades -1, -2 and -3, with -3 being the fastest.
Similarly, the high-performance devices are offered in three speed grades: -4, -5 and -6, with -6 being the
fastest. HC devices have an internal linear voltage regulator which supports external VCC supply voltages of
3.3V or 2.5V. ZE and HE devices only accept 1.2V as the external VCC supply voltage. With the exception of
power supply voltage all three types of devices (ZE, HC and HE) are functionally compatible and pin compatible
with each other.
The MachXO2 PLDs are available in a broad range of advanced halogen-free packages ranging from the space
saving 2.5x2.5 mm WLCSP to the 23x23 mm fpBGA. MachXO2 devices support density migration within the
same package.

2.0 LATTICE PRODUCT QUALIFICATION PROGRAM
Lattice Semiconductor Corp. maintains a comprehensive reliability qualification program to assure that each
product achieves its reliability goals. After initial qualification, the continued high reliability of Lattice products is
assured through ongoing monitor programs as described in Lattice Semiconductor‟s Reliability Monitor Program
Procedure (Doc. #70-101667).
All product qualification plans are generated in conformance with Lattice
Semiconductor‟s Qualification Procedure (Doc. #70-100164) with failure analysis performed in conformance with
Lattice Semiconductor‟s Failure Analysis Procedure (Doc. #70-100166). Both documents are referenced in
Lattice Semiconductor‟s Quality Assurance Manual, which can be obtained upon request from a Lattice
Semiconductor sales office. Figure 2.1 shows the Product Qualification Process Flow.
If failures occur during qualification, an 8D process is used to find root cause and eliminate the failure mode
from the design, materials, or process. The effectiveness of any fix or change is validated through additional
testing as required. Final testing results are reported in the qualification reports.
Failure rates in this reliability report are expressed in FITs. Due to the very low failure rate of integrated circuits,
it is convenient to refer to failures in a population during a period of 10 device hours; one failure in 10 device
hours is defined as one FIT.

Product families are qualified based upon the requirements outlined in Table 2.2.
In general, Lattice
Semiconductor follows the current Joint Electron Device Engineering Council (JEDEC) and Military Standard
testing methods. Lattice automotive products are qualified and characterized to the Automotive Electronics
Council (AEC) testing requirements and methods. Product family qualification will include products with a wide
range of circuit densities, package types, and package lead counts. Major changes to products, processes, or
vendors require additional qualification before implementation.
The MachXO2 family is the third generation FPGA product family and first 65 nm (CS200FL) Flash Technology
based product offering. The Lattice Semiconductor MachXO2 FPGA product family qualification efforts are
based on the first MachXO2 devices in the family per the Lattice Semiconductor Qualification Procedure,
doc#70-100164.
Lattice Semiconductor maintains a regular reliability monitor program. The current Lattice Reliability Monitor
Report can be found at www.latticesemi.com/lit/docs/qa/product_reliability_monitor.pdf .
