Speeds down to 20 ns and power dissipation as low as 14.4 mW are offered. All speed ranges are specified over the 3.0V to 5.5V range. All pins offer a low 10 A leakage. (continued) Pin Configurations Pin Name CLK/IN IN I/O * VCC Function Clock and Logic Input Logic Inputs Bidirectional Buffers No Internal Connection 3.0V to 5.5V Supply DIP/SOIC PLCC Rev. 0190C--05/98 1 The AT22LV10L provides the optimum low power CMOS PLD solution, with low DC power (1 mA typical at V CC = 3.3V) and full CMOS output levels. The AT22LV10L significantly reduces total system power, allowing battery powered operation. Full CMOS output levels help reduce power in many other system components. The AT22LV10 and AT22LV10L logic architectures are identical to the familiar 22V10. Each output 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 asynchronous reset. These terms are common to all ten registers. All registers are automatically cleared upon power up. Register preload simplifies testing. A security fuse prevents unauthorized copying of programmed fuse patterns.

This feature will simplify testing since any state can be forced into the registers to control 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 11.5V 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 registers. Level forced on registered output pin during preload cycle VIH VIL Register state after cycle High Low 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. However, due to the asynchronous nature of reset and the uncertainty of how VCC actually rises in the system, the following conditions are required: 1. The VCC rise must be monotonis; 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.

Typical values for nominal supply voltage. This parameter is only sampled and is not 100% tested. Erasure Characteristics The entire fuse array of an AT22LV10 or AT22LV10L is erased after exposure to ultraviolet light at a wavelength of 2537 A. Complete erasure is assured after a minimum of 20 minutes exposure using 12,000 W/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 unintentional erasure, an opaque label is recommended to cover the clear window on any UV erasable PLD which will be subjected to continuous fluorescent indoor lighting or sunlight. 7 8 AT22LV10(L) AT22LV10(L) 9 Ordering Information tPD (ns) 20 tS (ns) 10 tCO (ns) 14 Ordering Code AT22LV10-20JC AT22LV10-20PC AT22LV10-20SC AT22LV10-20JI AT22LV10-20PI AT22LV10-20SI 25 12 17 AT22LV10-25JC AT22LV10-25PC AT22LV10-25SC AT22LV10-25JI AT22LV10-25PI AT22LV10-25SI 25 17 14 AT22LV10L-25JC AT22LV10L-25PC AT22LV10L-25SC AT22LV10L-25JI AT22LV10L-25PI AT22LV10L-25SI Package 28J 24P3 24S 28J 24P3 24S 28J 24P3 24S 28J 24P3 24S 28J 24P3 24S 28J 24P3 24S Operation Range Commercial (0C to 70C) Industrial (-40C to 85C) Commercial (0C to 70C) Industrial (-40C to 85C) Commercial (0C to 70C) Industrial (-40C to 85C) Package Type 28J 24P3 24S 28-Lead, Plastic J-Leaded Chip Carrier OTP (PLCC) 24-Lead, 0.300" Wide, Plastic Dual Inline Package OTP (PDIP) 24-Lead, 0.300" Wide, Plastic Gull Wing Small Outline OTP (SOIC) 10 AT22LV10(L) AT22LV10(L) Packaging Information 28J, 28-Lead, Plastic J-Leaded Chip Carrier (PLCC) Dimensions in Inches and (Millimeters) JEDEC STANDARD MS-018 AB 24P3, 24-Lead, 0.300" Wide.
