ATF22V10CQZ-20XU

Programmable Logic Device Pld Overview

The ATF22V10CQZ-20XU is an electrically erasable programmable logic device (PLD) manufactured by Microchip Technology. It features a high-performance CMOS architecture with 10 macrocells and a maximum pin-to-pin propagation delay of 20 ns. The device operates at 5 V with industrial temperature range support (-40°C to +85°C). It utilizes Input Transition Detection (ITD) circuitry to achieve zero standby power, drawing a maximum of 100 µA in standby mode. The component is housed in a 24-lead Plastic Thin Shrink Small Outline Package (TSSOP).

Programmable Logic Device Pld Feature Summary

• Zero Standby Power: Utilizes Input Transition Detection (ITD) for automatic power-down, limiting standby current to 100 µA maximum.
• High Reliability: Features 20-year data retention, 100 erase/write cycles, and 2,000V ESD protection.
• Flexible Architecture: Contains 10 I/O macrocells with 8 to 16 product terms each, supporting registered or combinatorial output modes.
• CMOS/TTL Compatibility: Inputs and outputs are compatible with both CMOS and TTL voltage levels.

Programmable Logic Device Pld Applications

• Direct replacement for standard 22V10 family PLDs and most 24-pin combinatorial PLDs.
• State machine initialization utilizing power-up reset functionality.
• PCI compliant digital logic design applications.

Programmable Logic Device Pld Procurement Notes

Verify the package type corresponds to the 'X' suffix, indicating a 24-lead TSSOP. Confirm the 'I' designation for Industrial temperature range (-40°C to +85°C) and the '-20' speed grade matching the 20 ns maximum delay. Ensure the ordering code matches the specific green package option if RoHS compliance is required.

Programmable Logic Device Pld Selection Notes

Select this part when a 20 ns delay is acceptable within an industrial environment. The CQZ variant offers lower high-frequency supply current compared to the CZ series. Verify that the system can accommodate the 5V ±10% operating voltage range and that the 10 macrocell capacity meets the logic density requirements.

Programmable Logic Device Pld Part Context

This component belongs to the ATF22V10CQZ series, which serves as a successor to the obsolete ATF22V10CZ. The CQZ design combines low high-frequency ICC characteristics with Z-feature capabilities. It maintains architectural compatibility with the generic 22V10 family while providing enhanced power management through ITD technology.

Programmable Logic Device Pld Replacement Considerations

The ATF22V10CZ series is obsolete and replaced by the ATF22V10CQZ series. For direct functional replacement of older 22V10 devices, verify compiler mode settings (PAL or GAL) to ensure logical equivalence.
