ATF22LV10CQZ-30XC

Overview

The ATF22LV10CQZ-30XC is a high-performance, electrically erasable programmable logic device (PLD) manufactured by Microchip Technology. It features 12 inputs and 10 I/O macrocells with a variable product term architecture providing 8 to 16 terms per output. The device operates within a 3.0V to 5.5V supply range and delivers a maximum propagation delay of 30 ns. It incorporates Input Transition Detection (ITD) for zero standby power consumption, achieving a typical standby current of 5µA. The component utilizes CMOS technology compatible with both TTL and CMOS standards.

Feature Summary

• Low-voltage operation with 3.0V to 5.5V supply range
• Zero standby power via Input Transition Detection (ITD)
• 10 Macrocells with 8-16 variable product terms each
• CMOS and TTL compatible inputs and outputs

Applications

• Battery-powered systems requiring low power consumption
• Logic replacement for legacy PAL devices
• Industrial control applications within specified temperature ranges

Procurement Notes

Verify the package type corresponding to the 'X' suffix, which indicates a 24-lead Plastic Thin Shrink Small Outline (TSSOP). Confirm that the specific revision matches the industrial or commercial temperature requirements as defined in the ordering information table. Ensure programming equipment supports the EE Flash memory technology used in this PLD family.

Selection Notes

Select this part when a low-power, reprogrammable logic solution is needed with 10 I/O lines. The -30 speed grade offers a 30 ns maximum delay suitable for moderate-speed digital logic. Consider the TSSOP package if space constraints require a surface-mount footprint smaller than SOIC or PDIP options available in the same series.

Part Context

This component belongs to the ATF22LV10CQZ series, representing the second-generation low-voltage PLDs from Atmel/Microchip. It serves as the successor to the older ATF22LV10CZ series, offering improved power efficiency through the ITD feature while maintaining pin compatibility with standard 24-pin PLD packages.

Replacement Considerations

The ATF22LV10CZ series is obsolete and replaced by the CQZ variants. For direct functional replacement, verify pinout compatibility with other 24-pin PLDs such as the ATF22V10CZ, noting differences in voltage levels and power characteristics.
