ATF22V10CQZ-20JI

Programmable Logic Device Pld Overview

The ATF22V10CQZ-20JI is an electrically erasable programmable logic device (EEPLD) manufactured by Microchip Technology, formerly Atmel. It features a high-performance CMOS architecture with 12 inputs and 10 I/O macrocells. The maximum pin-to-pin propagation delay is 20 ns, supporting a maximum operating frequency of 50 MHz. It operates at 5 V with a standby power consumption of up to 120 µA in industrial temperature ranges (-40°C to +85°C). The device utilizes Input Transition Detection for zero-power standby modes and includes latch features to hold input states.

Programmable Logic Device Pld Feature Summary

• Zero Power Standby: Utilizes Input Transition Detection (ITD) to achieve low standby current (max 120 µA).
• High Reliability: Features 20-year data retention, 100 erase/write cycles, and 200mA latchup immunity.
• Flexible Architecture: Supports PAL, GAL, and Synario compiler modes with 10 macrocells offering registered or combinatorial outputs.
• Industrial Grade: Operates reliably within the -40°C to +85°C temperature range.

Programmable Logic Device Pld Applications

• Direct replacement for standard 22V10 family PLDs and most 24-pin combinatorial PLDs.
• State machine initialization requiring power-up reset functionality.
• Logic functions requiring reprogrammability and security fuse protection.
• Systems requiring low standby power management through automatic power-down modes.

Programmable Logic Device Pld Procurement Notes

Verify that the component matches the specific speed grade and package type required for the design. Confirm compliance with RoHS standards if lead-free packaging is necessary. Ensure programming equipment supports the Electrically Erasable Flash memory technology used in this device. Check for any export restrictions or documentation requirements associated with the part number before ordering.

Programmable Logic Device Pld Selection Notes

Select the ATF22V10CQZ-20JI when a 20 ns delay specification is acceptable and industrial temperature operation is required. Compare against commercial variants if lower cost is prioritized over extended temperature range. Consider the CQZ series over the obsolete CZ series for new designs due to improved power characteristics and availability. Ensure the design accommodates the 5V supply voltage tolerance of ±10%.

Programmable Logic Device Pld Part Context

This part belongs to the ATF22V10CQZ family, which supersedes the older ATF22V10CZ series. The 'Q' designation indicates the advanced low-power design, while 'Z' denotes RoHS-compliant green packaging options. The 'I' suffix specifies the industrial temperature rating, distinguishing it from commercial grade parts. This lineage ensures compatibility with legacy 22V10 applications while offering enhanced reliability and power efficiency.

Programmable Logic Device Pld Replacement Considerations

The ATF22V10CZ series is obsolete and replaced by the ATF22V10CQZ series. When replacing older devices, ensure the compiler mode settings match the original design intent. Verify that the power supply can handle the active current draw during operation, as standby currents are significantly reduced in the CQZ variant compared to previous generations.

Programmable Logic Device Pld FAQ

What is the maximum operating frequency for the ATF22V10CQZ-20JI?

The maximum operating frequency is 50 MHz, determined by the 20 ns propagation delay and setup time specifications.

How does the device achieve zero standby power?

It uses patented Input Transition Detection (ITD) circuitry that automatically powers down the device to zero power mode when idle, limiting standby current to a maximum of 120 µA.

Can this device replace a standard 22V10 PAL?

Yes, the ATF22V10CQZ incorporates a superset of the generic 22V10 architecture, allowing direct replacement in most applications using standard 24-pin combinatorial PLDs.
