*NOTICE:

Stresses beyond those listed under “Absolute Maxi-

mum Ratings” may cause permanent damage to the

device. This is a stress rating only and functional

operation of the device at these or any other condi-

tions beyond those indicated in the operational sec-

tions of this specification is not implied. Exposure to

absolute maximum rating conditions for extended

periods may affect device reliability.

Note:

1. Minimum voltage is -0.6V dc whihc may undershoot

to -2.0V for pulses of less than 20 ns. Maximum pin

Preload of Registered Outputs

The registers in the AT22LV10 and AT22LV10L are pro-

vided with circuitry to allow loading of each register asyn-

chronously with either a high or a low. This feature will

simplify testing since any state can be forced into the regis-

ters to control test sequencing. A V_IHlevel on the I/O pin

will force the register high; a V_ILwill force it low, indepen-

dent of the polarity bit (C0) setting. The preload state is

entered by placing an 11.5V to 13V signal on pin 8 on

DIPs, and pin 10 on SMPs. When the clock pin is pulsed

high, the data on the I/O pins is placed into the ten regis-

ters.

Power-Up Reset

The registers in the AT22LV10 and AT22LV10L are

designed to reset during power up. At a point delayed

slightly from VCC crossing 2.5V, all registers will be reset

to the low state. The output state will depend on the polarity

of the output buffer.

This feature is critical for state machine initialization. How-

ever, due to the asynchronous nature of reset and the

uncertainty of how VCC actually rises in the system, the fol-

lowing conditions are required:

1. The V_CCrise must be monotonis;

2. After reset occurs, all input and feedback setup

times must be met before driving the clock pin high,

Erasure Characteristics

The entire fuse array of an AT22LV10 or AT22LV10L is

erased after exposure to ultraviolet light at a wavelength of

2537 Å. Complete erasure is assured after a minimum of

20 minutes exposure using 12,000 µW/cm²intensity lamps

spaced one inch away from the chip. Minimum erase time

for lamps at other intensity ratings can be calculated from

the minimum integrated erasure dose of 15 W^•sec/cm². To

prevent unintentional erasure, an opaque label is recom-

mended to cover the clear window on any UV erasable

PLD which will be subjected to continuous fluorescent

indoor lighting or sunlight.
