8
© LATTICE SEMICONDUCTOR CORPORATION Uudet mikropiirit Low Density January Lattice Confidential Key Poitns •Digital Logic Uses Only Two Values: 1 and 0 •1 and 0 usually represent a voltage •Example –Digital 1 = 5 volts –Digital 0 = 0 volts OR –1 = ON, 0 = Off –1 = True, 0 = False

9
© LATTICE SEMICONDUCTOR CORPORATION Uudet mikropiirit Low Density January Lattice Confidential Boolean Basics •Manipulation of digital values is done by Boolean Algebra •Boolean algebra uses primarily AND / OR functions •Boolean equation: TRUE OR FALSE = TRUE •Programmable logic implements the AND / OR functions in hardware

10
© LATTICE SEMICONDUCTOR CORPORATION Uudet mikropiirit Low Density January Lattice Confidential Basic Gates •A gate performs a logic function in hardware •Three basic PLD gate types –AND gates –OR gates –Exclusive-OR (XOR) gates •Gates can have any number of inputs

11
© LATTICE SEMICONDUCTOR CORPORATION Uudet mikropiirit Low Density January Lattice Confidential AND Gate Example •Output of an AND gate is TRUE only if all inputs are TRUE –In a 2 input gate both switches must be on to turn the light on OFF ON OFF ON OFF ON

12
© LATTICE SEMICONDUCTOR CORPORATION Uudet mikropiirit Low Density January Lattice Confidential OFF ON OFF ON Or Gate Example •Output of OR Gate Is TRUE if ANY Input is TRUE –If Either Switch Is ON, The Light Will Trun ON ON

13
© LATTICE SEMICONDUCTOR CORPORATION Uudet mikropiirit Low Density January Lattice Confidential XOR Gate Example •Output of XOR Gate Is TRUE Only of One Input Is TRUE –If Only One Switch Is ON, The Light Will Turn ON OFF ON OFF ON OFF

© LATTICE SEMICONDUCTOR CORPORATION Uudet mikropiirit Low Density January Lattice Confidential GAL Devices •Low density GAL product families: 16/20V8, 18/22V10/26V12, 20RA10, 20XV10, 6001/6002. Families are organized based on architectural layout and a common Output Logic Macro Cell (OLMC). Pin counts and array sizes are all that change across a family. •Lattice GAL devices have Macro Cell counts from 8 to 39 and package sizes from 20 pins to 28 pins. •All GAL devices have registered or combinatorial options, OE control, and selectable output polarity.

21
© LATTICE SEMICONDUCTOR CORPORATION Uudet mikropiirit Low Density January Lattice Confidential GAL Devices •There are also various flavors of each device type. –An L in the product name is a low voltage (3.3V) device. –Zero power devices are either Z or ZD, such as 22LV10ZD. –A VP indicates high drive outputs, such as the 16VP8. –The ispGAL16Z8 was the worlds first ISP PLD. –There is also a Confusion Letter, which roughly indicates the process and technology that the device is based on. •Appended to each device type are speed, power, package, etc. –Device speed grades are by TPD in ns. (HD devices are graded by Fmax in MHz.) –Power dissipation (standard, Low, and Quarter), package type (Pdip, Jlcc, Soic), and Temp/VCC range are appended to device names such as 16LV8C-5LJI for 5nS, low power, PLCC, Industrial.

22
© LATTICE SEMICONDUCTOR CORPORATION Uudet mikropiirit Low Density January Lattice Confidential PAL Vs. GAL •PAL: –Programmable Array Logic. –Registers, feedback paths, dynamic I/O, and both output polarities are available. –There are dozens of different devices each with a fixed architecture. For example, a PAL16H2 has 16 inputs and 2 combinatorial outputs each with 8 PTs per OR gate. Output polarity is positive. •GAL: –Generic Array Logic. –GALs are a superset of PALs. A few GAL devices cover all PAL architectures and hundreds of other possible configurations. –GALs add extremely flexible routing and complete reconfigurability. –The structure of GAL devices allows them to replace many PALs with various IO, input and register counts. Therefore, extra programmable areas known as architecture rows are needed for device configuration. There are global configuration modes and well as individual MacroCell options.
