ATF22V10CQZ-20PI

Overview

The ATF22V10CQZ-20PI is an electrically erasable programmable logic device (EEPLD) manufactured by Microchip Technology. It features a high-performance CMOS architecture with 12 inputs and 10 I/O macrocells, providing up to 16 product terms per macrocell. The device operates at a maximum propagation delay of 20 ns and supports a maximum frequency of 50 MHz. It utilizes advanced Flash memory technology for reprogrammability and offers zero standby power dissipation through Input Transition Detection (ITD). The component is housed in a 24-pin Plastic Dual Inline Package (PDIP) and is rated for industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Zero Power Dissipation: Achieves 100µA maximum standby power via patented Input Transition Detection (ITD) circuitry.
• High-Speed Performance: Delivers a maximum pin-to-pin delay of 20 ns with a maximum operating frequency of 50 MHz.
• Advanced Flash Memory: Utilizes electrically erasable Flash technology allowing for 100 erase/write cycles and 20-year data retention.
• Universal Architecture: Emulates most 24-pin PAL devices and includes latch features to hold inputs to the previous logic state.

Applications

• Direct replacement for 22V10 family and other 24-pin combinatorial PLDs.
• Implementation of complex logic functions using three configurable modes of operation.
• State machine initialization utilizing power-up reset and register preload capabilities.
• Low-power system designs requiring automatic power-down during idle states.

Procurement Notes

Verify that the ordering suffix 'PI' corresponds to the 24-pin PDIP package and Industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status as the datasheet indicates green package options are available. Ensure programming hardware supports the specific Flash memory requirements of the ATF22V10CQZ series.

Selection Notes

Select this part when a 20 ns speed grade is required within the ATF22V10CQZ family. The 'I' suffix denotes the industrial temperature range, while 'P' specifies the PDIP package. Compare against commercial variants if lower cost is prioritized over extended temperature performance. Consider the 12 input and 10 I/O configuration for logic density requirements.

Part Context

The ATF22V10CQZ-20PI belongs to the ATF22V10C(Q)Z series, which supersedes the obsolete ATF22V10CZ. This series combines low high-frequency ICC of the 'Q' design with the 'Z' feature set. It is designed to be a drop-in replacement for legacy GAL and PAL devices, offering enhanced reliability through a high-reliability CMOS process and 200mA latchup immunity.

Replacement Considerations

The ATF22V10CZ series is obsolete and replaced by the ATF22V10CQZ. For direct functional replacement of 22V10 architectures, verify compiler mode settings (PAL or GAL mode) in design software. Ensure voltage levels match the 5V ±10% requirement for industrial applications.
