ATF22V10CZ-15PC

Overview

The ATF22V10CZ-15PC 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 15 ns, supporting a maximum operating frequency of 83.3 MHz. It operates at a supply voltage of 5 V ±10% within the industrial temperature range of -40°C to +85°C. The device utilizes Flash memory technology for reprogrammability and offers zero standby power dissipation through Input Transition Detection circuitry.

Feature Summary

• Zero Standby Power: Achieves 100 µA maximum standby current via Input Transition Detection (ITD).
• Reprogrammable Architecture: Utilizes Electrically Erasable Flash memory with 100 erase/write cycles.
• High Reliability: Features 20-year data retention, 2,000V ESD protection, and 200mA latchup immunity.
• CMOS/TTL Compatibility: Inputs and outputs are compatible with both CMOS and TTL logic levels.

Applications

• Direct replacement for standard 22V10 family PLDs and most 24-pin combinatorial PLDs.
• State machine implementation utilizing power-up reset functionality.
• Complex logic functions requiring registered or combinatorial output configurations.

Procurement Notes

Verify that the component matches the specific package type indicated by the ordering suffix. Confirm the operational temperature range requirements against the datasheet specifications for commercial versus industrial grades. Ensure programming equipment supports the required voltage levels for the EEPLD architecture.

Selection Notes

Select this part for applications requiring low-power operation with zero standby current when idle. The 15 ns speed grade is suitable for systems operating up to 83.3 MHz. Consider the ATF22V10CQZ series as the recommended successor, as the ATF22V10CZ line is obsolete and not recommended for new designs.

Part Context

This component belongs to the ATF22V10C(Q)Z family of high-performance EEPLDs. The 'Z' suffix denotes the inclusion of the zero-power feature set. The 'PC' in the model number specifies the 24-pin Plastic Dual Inline Package (PDIP) variant. This device serves as a superset of the generic 22V10 architecture.

Replacement Considerations

The ATF22V10CZ series is obsolete and replaced by the ATF22V10CQZ series. For equivalent performance in industrial applications, consider the ATF22V10CQZ-20PI or ATF22V10CQZ-20PU.

FAQ

How does the device achieve zero standby power?

The device uses patented Input Transition Detection (ITD) circuitry to automatically power down to zero power mode when the device is idle.

What is the maximum operating frequency for this speed grade?

The maximum operating frequency is 83.3 MHz, determined by the 15 ns propagation delay.

Is the security fuse programmable?

Yes, a single security fuse can be programmed to prevent unauthorized copying of the fuse patterns, though the 64-bit User Signature remains accessible.
