ATF22V10CQZ-20XC

Overview

The ATF22V10CQZ-20XC is a high-performance CMOS electronically erasable programmable logic device (EEPLD) manufactured by Microchip Technology. It features 12 inputs and 10 I/O macrocells with a maximum pin-to-pin propagation delay of 20 ns. The device operates at 5 V with a typical standby current of 5 µA, utilizing Input Transition Detection for zero-power mode. It supports industrial temperature ranges (-40°C to +85°C) and includes features such as latch hold, security fuses, and a 64-bit user signature.

Feature Summary

• Maximum 20 ns propagation delay with 10 macrocells
• Zero standby power via Input Transition Detection (ITD)
• Industrial temperature range (-40°C to +85°C)
• CMOS/TTL compatible with 200mA latchup immunity

Applications

• Direct replacement for 22V10 family PLDs
• State machine initialization with power-up reset
• PCI compliant logic interfacing

Procurement Notes

Verify the package type '24X' corresponds to TSSOP-24. Confirm the suffix 'XC' indicates the commercial temperature grade (0°C to 70°C) despite the datasheet listing 'XI' for industrial. Check for RoHS compliance status as older 'CZ' variants are obsolete.

Selection Notes

Select this part for designs requiring 20 ns speed in a 24-pin surface mount package. Ensure compiler settings match the GAL or PAL mode requirements. Verify voltage levels against the 5V ±10% specification for industrial applications if used outside commercial limits.

Part Context

This component belongs to the ATF22V10CQZ series, which supersedes the obsolete ATF22V10CZ. It combines low high-frequency ICC with zero-power features. The 'CQZ' designation distinguishes it from the standard 'CZ' variant.

Replacement Considerations

The ATF22V10CZ is obsolete and replaced by the ATF22V10CQZ. For industrial temperature operation, consider the ATF22V10CQZ-20XI variant instead of the commercial XC version.

FAQ

What is the maximum operating frequency?

The maximum external feedback frequency is 38.5 MHz.

How does the device achieve zero standby power?

It uses Atmel's patented Input Transition Detection (ITD) circuitry to automatically power down when idle.

Can unused product terms affect power consumption?

No, unused product terms are automatically disabled by the compiler to decrease power consumption.
