ATF22V10CQZ-20SI Description

The ATF22V10CQZ-20SI is an Electrically Erasable Programmable Logic Device (EE PLD) from Atmel (now Microchip Technology), designed for high-performance digital logic applications. This 20 ns speed-grade device operates at a 5V input voltage and features 10 macrocells, making it suitable for medium-complexity logic implementations. Packaged in a surface-mount tube, it belongs to the 22V10 series, known for its PAL-type architecture and CMOS technology. Though marked as obsolete, it remains relevant in legacy systems requiring reliable, low-power programmable logic solutions.

ATF22V10CQZ-20SI Features

• High-Speed Performance: 20 ns propagation delay ensures rapid logic execution for time-critical applications.
• EE PLD Flexibility: Electrically erasable design allows for reprogrammability, enabling iterative development and field updates.
• Low-Power CMOS: Efficient power consumption compared to bipolar PLDs, ideal for portable or power-sensitive systems.
• 10 Macrocells: Balanced logic density for state machines, glue logic, and interface control.
• Surface-Mount Package: Compact form factor (SOIC) suits space-constrained PCB designs.
• 5V Operation: Compatible with standard TTL logic levels, simplifying integration into existing designs.

ATF22V10CQZ-20SI Applications

• Legacy System Maintenance: Replacing obsolete PALs in industrial control or telecommunications equipment.
• Embedded Control: Custom logic for interfacing peripherals in microcontroller-based systems.
• Signal Routing & Decoding: Address decoding, bus arbitration, or timing control in digital circuits.
• Prototyping: Rapid development of mid-complexity logic before ASIC/FPGA commitment.
• Test Equipment: Customizable logic for instrumentation or automated test systems.

Conclusion of ATF22V10CQZ-20SI

The ATF22V10CQZ-20SI offers a cost-effective, reprogrammable solution for medium-speed logic designs, leveraging Atmel's proven CMOS PLD technology. While newer FPGAs dominate modern designs, this device remains valuable for retrofitting, low-volume production, or educational purposes where simplicity and reliability are prioritized. Its 20 ns speed and 5V compatibility ensure seamless adoption in legacy 5V systems, though designers should consider obsolescence risks for long-term projects.
