ATF22LV10CQZ-30PU

Overview

The ATF22LV10CQZ-30PU is an electrically erasable programmable logic device (EEPLD) manufactured by Microchip Technology, formerly Atmel. It features a high-performance CMOS architecture with 10 macrocells and 12 inputs. The device operates within a supply voltage range of 3.0V to 5.5V and supports industrial temperature ranges from -40°C to +85°C. Key electrical parameters include a maximum propagation delay of 30ns for non-registered outputs and a typical standby current of 5µA enabled by Input Transition Detection (ITD). It utilizes Flash memory technology for reprogrammability.

Feature Summary

• Low-power operation with 'zero' standby power mode (25µA max) via Input Transition Detection circuitry.
• CMOS and TTL-compatible I/Os with 5V tolerant inputs.
• Reprogrammable EE Flash memory with 10,000 erase/write cycles and 20-year data retention.
• Variable product term architecture allowing 8 to 16 product terms per output.

Applications

• Battery-powered systems requiring low standby current.
• Logic replacement for legacy PAL devices in industrial environments.
• State machine implementations utilizing synchronous preset and asynchronous reset features.

Procurement Notes

Verify the package type corresponds to the 'PU' suffix, which indicates a 24-pin Plastic Dual Inline Package (PDIP). Confirm that the specific revision meets RoHS compliance requirements if lead-free materials are mandated for the assembly process. Ensure programming equipment supports the specific voltage levels required for the EE Flash array.

Selection Notes

Select this component when a low-voltage PLD with minimal standby power is required compared to standard ATF22V10C variants. The CQZ series offers lower high-frequency ICC than the CZ series. Verify that the 30ns speed grade meets the system timing constraints and that the PDIP package fits the available board space.

Part Context

This part belongs to the ATF22LV10CQZ family, which serves as the low-voltage equivalent to the Atmel ATF22V10CZ. The ATF22LV10CZ is noted as obsolete and replaced by the CQZ variant. The 'PU' suffix specifically designates the industrial temperature range version housed in a 24-pin PDIP package.

Replacement Considerations

The ATF22LV10CZ is obsolete and replaced by the ATF22LV10CQZ series. For pin-compatible upgrades, consider other ATF22LV10CQZ variants with different package options such as SOIC or TSSOP if surface mount is preferred.
