ATF22V10CZ-15JI

Overview

The ATF22V10CZ-15JI is a high-performance Electrically Erasable Programmable Logic Device (EEPLD) 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 CMOS technology with zero standby power dissipation, consuming a typical standby current of 5 µA via Input Transition Detection. The component is housed in a 28-lead Plastic J-leaded Chip Carrier (PLCC) package and is rated for industrial operating temperatures ranging from -40°C to +85°C.

Feature Summary

• Zero Power Mode: Achieves 100 µA maximum standby power using patented Input Transition Detection circuitry.
• High Reliability: Offers 20-year data retention, 100 erase/write cycles, and 200mA latchup immunity.
• Flexible Architecture: Supports PAL, GAL, and Synario compiler modes with automatic configuration.
• Latch Feature: Includes input latches to hold previous logic states during idle periods.

Applications

• Replacement for standard 22V10 family PLDs and combinatorial logic circuits.
• State machine initialization requiring power-up reset functionality.
• Systems requiring low-power operation with automatic power-down capabilities.

Procurement Notes

Verify the specific ordering suffix 'JI' corresponds to the 28-lead PLCC package and Industrial temperature range (-40°C to +85°C). Confirm that the device meets RoHS compliance requirements if applicable, as older manufacturing runs may differ from current green package options. Check for export restrictions or documentation requirements associated with this specific part number before procurement.

Selection Notes

Select the ATF22V10CZ-15JI when a 15 ns speed grade is required within the industrial temperature range. Ensure the design accommodates the 28-lead PLCC footprint. For new designs, consider the ATF22V10CQZ series as the recommended replacement, as the CZ series is marked as not recommended for new designs. Verify voltage compatibility with the 5V ±10% supply requirement.

Part Context

This component belongs to the Atmel ATF22V10C(Q)Z family of high-performance EEPLDs. The datasheet explicitly states that the ATF22V10CZ series is obsolete and has been replaced by the ATF22V10CQZ series. The 'C' designation indicates commercial speed grades adapted for industrial use or specific timing characteristics, while 'Z' denotes the zero-power feature set.

Replacement Considerations

The ATF22V10CQZ-20JI is the officially recommended replacement for the ATF22V10CZ-15JI. While functionally compatible, the CQZ variant has a slower maximum propagation delay of 20 ns compared to the 15 ns of the CZ variant. Designers must verify that the increased delay meets system timing requirements.

FAQ

What is the maximum standby power consumption?

The device features a zero standby power mode with a maximum standby current of 100 µA, achieved through Input Transition Detection circuitry.

How many product terms are available per macrocell?

Each of the 10 I/O macrocells can be allocated between 8 and 16 product terms depending on the configuration.

Is this component suitable for new designs?

No, the datasheet explicitly states that the ATF22V10CZ is not recommended for new designs and should be replaced by the ATF22V10CQZ series.
