High Speed
UV Erasable
Programmable
Logic Device
Description
The AT22V10 and AT22V10L are CMOS high performance EPROM-based Programma-
ble Logic Devices (PLDs). Speeds down to 15 ns and power dissipation as low as 12 mA
are offered. All speed ranges are specified over the full 5 V ±10% range. All pins offer a
low ±10 µA leakage.
The AT22V10L provides the optimum low power CMOS PLD solution, with low DC power
(8 mA typical) and full CMOS output levels. The AT22V10L significantly reduces total
system power and enhances system reliability.
Full CMOS output levels help reduce power in many other system components.
The AT22V10 and AT22V10L incorporate a variable product term architecture. Each out-
put is allocated from eight to 16 product terms, which allows highly complex logic functions
to be realized.
Two additional product terms are included to provide synchronous preset and asynchro-
nous reset. These terms are common to all 10 registers. All registers are automatically
cleared upon power up.
Register preload simplifies testing. A security fuse prevents unauthorized copying of pro-
grammed fuse patterns.

Power Up Reset
The registers in the AT22V10 and AT22V10L are designed to
reset during power up. At a point delayed slightly from VCC
crossing 3.8 V, 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 uncer-
tainty of how VCC actually rises in the system, the following
conditions are required:
1) The VCC rise must be monotonic,
2) After reset occurs, all input and feedback setup times
must be met before driving the clock pin high, and
3) The clock must remain stable during tPR.Parameter Description Min Typ Max Units

Erasure Characteristics
The entire fuse array of an AT22V10 or AT22V10L 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/cm2 intensity 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 unin-
tentional erasure, an opaque label is recommended to cover
the clear window on any UV erasable PLD which will be sub-
jected to continuous fluorescent indoor lighting or sunlight.
Preload of Registered Outputs
The registers in the AT22V10 and AT22V10L are provided
with circuitry to allow loading of each register asynchro-
nously with either a high or a low. This feature will simplify
testing since any state can be forced into the registers to con-
trol test sequencing. A VIH level on the I/O pin will force the
register high; a VIL will force it low, independent of the polarity
bit (C0) setting. The preload state is entered by placing an
11.5-V to
13-V 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 registers.
