Overview
Lattice, the inventor of the Generic Array Logic™ (GAL®) family of low density, E2CMOS® PLDs is the leading supplier of low density CMOS PLDs in the world. Features such as industry leading performance, full reprogrammability, low power consumption, 100% testability and 100% programming yields make the GAL family the preferred
choice among system designers. The GAL family contains a comprehensive array of product architectures with a
variety of performance levels specified across commercial, industrial and military (MIL-STD-883) operating ranges
to meet the demands of any system logic design.
A Product for Any System Design Need
Lattice GAL products have the performance, architectural features, low power, and high quality to meet the needs
of the most demanding system designs.
Low Voltage Products
This rapidly growing family of 3.3V products support all speed, power and system logic level requirements.
Included are the world’s fastest PLDs (16LV8D, 20LV8D, 22LV10D and 26CLV12D) which are ideal for high performance, 3.3V logic applications. The 3.3V “zero power” (22LV10Z/ZD, LV22V10Z, 16/20LV8ZD) and the “low power”
(16LV8C, 22LV10C) product lines offer the flexibility of working in either 3.3V or mixed 3.3V and 5V systems. Insystem programmability is also available with the ispGAL22LV10.
Standard Products
Aimed at providing a superior design alternative to the bipolar PLD, the 16V8, 20V8, 22V10, 20RA10 and 20XV10
replace over 98% of all bipolar PAL devices. These GAL devices meet, and in most cases, beat bipolar PAL performance specifications while consuming significantly lower power and offering higher quality and reliability via Lattice
electrically reprogrammable E2CMOS technology.
Extension Products
These products provide enhanced functionality including innovative architectures (GAL18V10, GAL26CV12, and
GAL6001/6002), 64mA high output drive (GAL16VP8 and GAL20VP8), “zero power” operation (GAL16V8Z/ZD and
GAL20V8Z/ZD), and in-system programmability (ispGAL22V10).
