Description

DIP

The GAL22V10, at 4ns maximum propagation delay time, combines

a high performance CMOS process with Electrically Erasable (E²)

floating gate technology to provide the highest performance avail-

able of any 22V10 device on the market. CMOS circuitry allows

the GAL22V10 to consume much less power when compared to

bipolar 22V10 devices. E²technology offers high speed (<100ms)

erase times, providing the ability to reprogram or reconfigure the

device quickly and efficiently.

22V10

The generic architecture provides maximum design flexibility by

allowing the Output Logic Macrocell (OLMC) to be configured by

the user. The GAL22V10 is fully function/fuse map/parametric com-

patible with standard bipolar and CMOS 22V10 devices.

Specifications GAL22V10

Output Logic Macrocell (OLMC)

The GAL22V10 has a variable number of product terms per OLMC.

Of the ten available OLMCs, two OLMCs have access to eight

product terms (pins 14 and 23, DIP pinout), two have ten product

terms (pins 15 and 22), two have twelve product terms (pins 16 and

21), two have fourteen product terms (pins 17 and 20), and two

OLMCs have sixteen product terms (pins 18 and 19). In addition

to the product terms available for logic, each OLMC has an addi-

tional product-term dedicated to output enable control.

The GAL22V10 has a product term for Asynchronous Reset (AR)

and a product term for Synchronous Preset (SP). These two prod-

uct terms are common to all registered OLMCs. TheAsynchronous

Reset sets all registers to zero any time this dedicated product term

is asserted. The Synchronous Preset sets all registers to a logic

one on the rising edge of the next clock pulse after this product term

is asserted.

NOTE: TheAR and SP product terms will force the Q output of the

flip-flop into the same state regardless of the polarity of the output.

Therefore, a reset operation, which sets the register output to a zero,

may result in either a high or low at the output pin, depending on

the pin polarity chosen.

The output polarity of each OLMC can be individually programmed

to be true or inverting, in either combinatorial or registered mode.

This allows each output to be individually configured as either active

high or active low.

Specifications GAL22V10

Electronic Signature

Output Register Preload

An electronic signature (ES) is provided in every GAL22V10

device. It contains 64 bits of reprogrammable memory that can

contain user-defined data. Some uses include user ID codes,

revision numbers, or inventory control. The signature data is

always available to the user independent of the state of the se-

curity cell.

When testing state machine designs, all possible states and state

transitions must be verified in the design, not just those required

in the normal machine operations. This is because certain events

may occur during system operation that throw the logic into an

illegal state (power-up, line voltage glitches, brown-outs, etc.). To

test a design for proper treatment of these conditions, a way must

be provided to break the feedback paths, and force any desired

(i.e., illegal) state into the registers. Then the machine can be

sequenced and the outputs tested for correct next state condi-

tions.

The electronic signature is an additional feature not present in

other manufacturers' 22V10 devices. To use the extra feature of

the user-programmable electronic signature it is necessary to

choose 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 a

GAL22V10 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 to

use the GAL device's extra feature.

The GAL22V10 device includes circuitry that allows each regis-

tered output to be synchronously set either high or low. Thus, any

present state condition can be forced for test sequencing. If

necessary, approved GAL programmers capable of executing test

vectors perform output register preload automatically.

Input Buffers

The JEDEC map for the GAL22V10 contains the 64 extra fuses

for the electronic signature, for a total of 5892 fuses. However,

the GAL22V10 device can still be programmed with a standard

22V10 JEDEC map (5828 fuses) with any qualified device pro-

grammer.

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 and

tri-stated I/O pins be connected to an adjacent active input, Vcc,

or ground. Doing so will tend to improve noise immunity and

reduce Icc for the device. (See equivalent input and I/O schemat-

ics on the following page.)

Security Cell

A security cell is provided in every GAL22V10 device to prevent

unauthorized copying of the array patterns. Once programmed,

this cell prevents further read access to the functional bits in the

device. This cell can only be erased by re-programming the

device, so the original configuration can never be examined once

this cell is programmed. The Electronic Signature is always avail-

able to the user, regardless of the state of this control cell.

Typical Input Current

0

Latch-Up Protection

GAL22V10 devices are designed with an on-board charge pump

to negatively bias the substrate. The negative bias is of sufficient

magnitude to prevent input undershoots from causing the circuitry

to latch. Additionally, outputs are designed with n-channel pullups

instead of the traditional p-channel pullups to eliminate any pos-

sibility of SCR induced latching.

Device Programming

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.

OUTPUT REGISTER

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, the

state on the registered output pins (if they are enabled) will be

either high or low on power-up, depending on the programmed

polarity of the output pins. This feature can greatly simplify state

machine design by providing a known state on power-up. The

timing diagram for power-up is shown below. Because of the asyn-

chronous nature of system power-up, some conditions must be

met to guarantee a valid power-up reset of the GAL22V10. First,

the Vcc rise must be monotonic. Second, the clock input must

be 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 and

feedback path setup times have been met. The clock must also

meet the minimum pulse width requirements.
