ATF22V10CZ-15SC

Overview

The ATF22V10CZ-15SC is a high-performance CMOS electrically erasable programmable logic device (PLD) manufactured by Microchip Technology. It features 12 inputs and 10 I/O macrocells, with each macrocell supporting 8 to 16 product terms. The device operates at a maximum propagation delay of 15 ns and supports a maximum frequency of 83.3 MHz. It utilizes Flash memory technology for reprogrammability and offers zero standby power through Input Transition Detection circuitry. The component is housed in a 24-lead SOIC package and is designed for commercial temperature ranges.

Feature Summary

• Zero Standby Power: Utilizes Input Transition Detection (ITD) to automatically power down when idle, achieving typical standby current of 5µA and maximum of 100µA.
• High Reliability: Features 20-year data retention, 100 erase/write cycles, 2,000V ESD protection, and 200mA latchup immunity.
• Universal Architecture: Compatible with industry-standard pinouts, allowing direct replacement of most 24-pin combinatorial PLDs and PAL devices.
• CMOS/TTL Compatibility: Inputs and outputs are compatible with both CMOS and TTL logic levels.

Applications

• State machine implementation requiring power-down capabilities
• Replacement for legacy 22V10 family PLDs
• General-purpose digital logic interfacing

Procurement Notes

Verify the specific speed grade and package configuration against the ordering information table. Note that the ATF22V10CZ series is marked as obsolete and not recommended for new designs; transition to the ATF22V10CQZ series is advised. Confirm RoHS compliance status if required for the application environment.

Selection Notes

Select this component for applications requiring low-power PLD functionality with Flash reprogrammability. Ensure the operating temperature range matches the commercial specification (0°C to 70°C). For industrial temperature requirements (-40°C to +85°C), consider the Industrial grade variants or downgrade the speed grade of the commercial part while de-rating power consumption by 30%.

Part Context

This device belongs to the ATF22V10C(Q)Z family of Electrically Erasable Programmable Logic Devices. It serves as a successor to earlier GAL-based PLDs, offering non-volatile Flash memory storage which eliminates the need for UV erasure. The 'Z' suffix indicates the inclusion of the zero-power feature set.

Replacement Considerations

The ATF22V10CZ series is officially obsolete and replaced by the ATF22V10CQZ series. When replacing existing designs, verify that the CQZ variant meets the timing and power specifications of the original CZ part.

FAQ

How does the device achieve zero standby power?

The device uses Atmel's patented Input Transition Detection (ITD) circuitry. When the device is idle, it automatically powers down to a zero power mode, consuming only leakage current.

What is the maximum number of product terms per macrocell?

Each of the ten I/O macrocells can be allocated up to 16 product terms.

Is the security fuse programmable?

Yes, a single security fuse is provided to prevent unauthorized copying of the fuse patterns. Once programmed, fuse verify and preload are inhibited, though the 64-bit User Signature remains accessible.
