DESCRIPTION

The GAL22V10, at 4ns maximum propagation delay time, com-bines a high performance CMOS process with Electrically Eras-able (E2) floating gate technology to provide the highest perform-ance available of any 22V10 device on the market. CMOS cir-cuitry allows the GAL22V10 to consume much less power whencompared to bipolar 22V10 devices. E2 technology offers highspeed (<100ms) erase times, providing the ability to reprogramor reconfigure the device quickly and efficiently.

The generic architecture provides maximum design flexibility byallowing the Output Logic Macrocell (OLMC) to be configured bythe user. The GAL22V10 is fully function/fuse map/parametriccompatible with standard bipolar and CMOS 22V10 devices.

Unique test circuitry and reprogrammable cells allow completeAC, DC, and functional testing during manufacture. As a result,Lattice Semiconductor delivers 100% field programmability andfunctionality of all GAL products. In addition, 100 erase/writecycles and data retention in excess of 20 years are specified.

OUTPUT LOGIC MACROCELL (OLMC)

OUTPUT LOGIC MACROCELL CONFIGURATIONS

GAL22V10 OUTPUT LOGIC MACROCELL (OLMC)

Each of the Macrocells of the GAL22V10 has two primary func-tional modes: registered, and combinatorial I/O. The modes andthe output polarity are set by two bits (SO and S1), which are nor-mally controlled by the logic compiler. Each of these two primarymodes, and the bit settings required to enable them, are describedbelow and on the following page.

REGISTEREDIn registered mode the output pin associated with an individualOLMC is driven by the Q output of that OLMC’s D-type flip-flop.Logic polarity of the output signal at the pin may be selected byspecifying that the output buffer drive either true (active high) orinverted (active low). Output tri-state control is available as an in-dividual product-term for each OLMC, and can therefore be de-fined by a logic equation. The D flip-flop’s /Q output is fed backinto the AND array, with both the true and complement of thefeedback available as inputs to the AND array.

NOTE: In registered mode, the feedback is from the /Q output ofthe register, and not from the pin; therefore, a pin defined asregistered is an output only, and cannot be used for dynamicI/O, as can the combinatorial pins.

COMBINATORIAL I/OIn combinatorial mode the pin associated with an individual OLMCis driven by the output of the sum term gate. Logic polarity of theoutput signal at the pin may be selected by specifying that theoutput buffer drive either true (active high) or inverted (active low).Output tri-state control is available as an individual product-termfor each output, and may be individually set by the compiler aseither “on” (dedicated output), “off” (dedicated input), or “product-term driven” (dynamic I/O). Feedback into the AND array is fromthe pin side of the output enable buffer. Both polarities (true andinverted) of the pin are fed back into the AND array.

The GAL22V10 has a variable number of product terms perOLMC. Of the ten available OLMCs, two OLMCs have access toeight product terms (pins 14 and 23, DIP pinout), two have tenproduct terms (pins 15 and 22), two have twelve product terms(pins 16 and 21), two have fourteen product terms (pins 17 and20), and two OLMCs have sixteen product terms (pins 18 and 19).In addition to the product terms available for logic, each OLMChas an additional product-term dedicated to output enable control.

The output polarity of each OLMC can be individually programmedto be true or inverting, in either combinatorial or registered mode.This allows each output to be individually configured as eitheractive high or active low.

The GAL22V10 has a product term for Asynchronous Reset (AR)and a product term for Synchronous Preset (SP). These twoproduct terms are common to all registered OLMCs. The Asyn-chronous Reset sets all registers to zero any time this dedicatedproduct term is asserted. The Synchronous Preset sets all reg-isters to a logic one on the rising edge of the next clock pulse afterthis product term is asserted.

NOTE: The AR and SP product terms will force the Q output ofthe flip-flop into the same state regardless of the polarity of theoutput. Therefore, a reset operation, which sets the register outputto a zero, may result in either a high or low at the output pin,depending on the pin polarity chosen.

Note: fmax with external feedback is cal-culated from measured tsu and tco.

fmax with External Feedback 1/( tsu+tco)

Note: tcf is a calculated value, derived by sub-tracting tsu from the period of fmax w/internalfeedback (tcf = 1/fmax - tsu). The value of tcf isused primarily when calculating the delay fromclocking a register to a combinatorial output(through registered feedback), as shown above.For example, the timing from clock to a combi-natorial output is equal to tcf + tpd.

fmax with No Feedback

Note: fmax with no feedback may be lessthan 1/(twh + twl). This is to allow for aclock duty cycle of other than 50%.

ELECTRONIC SIGNATURE

An electronic signature (ES) is provided in every GAL22V10device. It contains 64 bits of reprogrammable memory that cancontain user-defined data. Some uses include user ID codes,revision numbers, or inventory control. The signature data isalways available to the user independent of the state of the se-curity cell.

The electronic signature is an additional feature not present inother manufacturers' 22V10 devices. To use the extra feature ofthe user-programmable electronic signature it is necessary tochoose a Lattice Semiconductor 22V10 device type when com-piling a set of logic equations. In addition, many device program-mers have two separate selections for the device, typically aGAL22V10 and a GAL22V10-UES (UES = User Electronic Sig-nature) or GAL22V10-ES. This allows users to maintain compat-ibility with existing 22V10 designs, while still having the option touse the GAL device's extra feature.

The JEDEC map for the GAL22V10 contains the 64 extra fusesfor the electronic signature, for a total of 5892 fuses. However,the GAL22V10 device can still be programmed with a standard22V10 JEDEC map (5828 fuses) with any qualified device pro-grammer.

OUTPUT REGISTER PRELOAD

When testing state machine designs, all possible states and statetransitions must be verified in the design, not just those requiredin the normal machine operations. This is because certain eventsmay occur during system operation that throw the logic into anillegal state (power-up, line voltage glitches, brown-outs, etc.). Totest a design for proper treatment of these conditions, a way mustbe provided to break the feedback paths, and force any desired(i.e., illegal) state into the registers. Then the machine can besequenced and the outputs tested for correct next state condi-tions.

The GAL22V10 device includes circuitry that allows each regis-tered output to be synchronously set either high or low. Thus, anypresent state condition can be forced for test sequencing. Ifnecessary, approved GAL programmers capable of executing testvectors perform output register preload automatically.

INPUT BUFFERS

GAL22V10 devices are designed with TTL level compatible in-put buffers. These buffers have a characteristically high imped-ance, and present a much lighter load to the driving logic than bi-polar TTL devices.

The input and I/O pins also have built-in active pull-ups. As a re-sult, floating inputs will float to a TTL high (logic 1). However,Lattice Semiconductor recommends that all unused inputs andtri-stated I/O pins be connected to an adjacent active input, Vcc,or ground. Doing so will tend to improve noise immunity andreduce Icc for the device. (See equivalent input and I/O schemat-ics on the following page.)

Typical Input Current

SECURITY CELL

A security cell is provided in every GAL22V10 device to preventunauthorized copying of the array patterns. Once programmed,this cell prevents further read access to the functional bits in thedevice. This cell can only be erased by re-programming thedevice, so the original configuration can never be examined oncethis cell is programmed. The Electronic Signature is always avail-able to the user, regardless of the state of this control cell.

LATCH-UP PROTECTION

GAL22V10 devices are designed with an on-board charge pumpto negatively bias the substrate. The negative bias is of sufficientmagnitude to prevent input undershoots from causing the circuitryto latch. Additionally, outputs are designed with n-channel pullupsinstead of the traditional p-channel pullups to eliminate any pos-sibility of SCR induced latching.

GAL devices are programmed using a Lattice Semiconductor-approved Logic Programmer, available from a number of manu-facturers (see the the GAL Development Tools section). Com-plete programming of the device takes only a few seconds. Eras-ing of the device is transparent to the user, and is done automati-cally as part of the programming cycle.

POWER-UP RESET

(Vref Typical = 3.2V)

(Vref Typical = 3.2V)

Circuitry within the GAL22V10 provides a reset signal to all reg-isters during power-up. All internal registers will have their Q out-puts set low after a specified time (tpr, 1µs MAX). As a result, thestate on the registered output pins (if they are enabled) will beeither high or low on power-up, depending on the programmedpolarity of the output pins. This feature can greatly simplify statemachine design by providing a known state on power-up. Thetiming diagram for power-up is shown below. Because of the asyn-

chronous nature of system power-up, some conditions must bemet to guarantee a valid power-up reset of the GAL22V10. First,the Vcc rise must be monotonic. Second, the clock input mustbe at static TTL level as shown in the diagram during power up.The registers will reset within a maximum of tpr time. As in nor-mal system operation, avoid clocking the device until all input andfeedback path setup times have been met. The clock must alsomeet the minimum pulse width requirements.
