ATF22V10C-15PI Equivalent & Substitute Parts

Part Overview

The ATF22V10C-15PI is a 22V10 Programmable Logic Device (PLD) IC manufactured by Microchip Technology, featuring 10 macrocells with 15 nanosecond propagation delay in a 24-pin DIP package. This component is classified as obsolete, indicating discontinued production and limited availability through standard distribution channels. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure project feasibility, and secure long-term component supply for legacy systems and new designs requiring this functional specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATF22V10C-15PI is determined by strict equivalence across the following parameters: series designation (22V10), programmable type (EE PLD), macrocell count (10), input voltage specification (5V), speed rating (15 ns), mounting technology (Through Hole), and physical package format (24-DIP). The ATF22V10C-15PU qualifies as a direct substitute based on identical electrical and mechanical specifications. The primary distinction between these parts is packaging format (tube versus DIP) and product status (active versus obsolete), which do not affect functional compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The ATF22V10C-15PU is the direct functional equivalent of the ATF22V10C-15PI. Selection between these parts should be based on the following criteria:

The ATF22V10C-15PI is obsolete and presents supply chain risk. The ATF22V10C-15PU maintains active product status with verified programmability and higher inventory availability, making it the preferred choice for new designs and ongoing production requirements.

For applications subject to RoHS compliance mandates, the ATF22V10C-15PU satisfies ROHS3 requirements, whereas the ATF22V10C-15PI does not. Both parts carry identical REACH and ECCN classifications.

Both components are electrically and mechanically interchangeable within circuit designs. No schematic modifications, PCB layout changes, or firmware adjustments are required when transitioning from ATF22V10C-15PI to ATF22V10C-15PU.

Frequently Asked Questions (FAQ)

Q: Can ATF22V10C-15PU replace ATF22V10C-15PI in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all functional parameters: 10 macrocells, 5V input, 15 ns speed, and 24-PDIP package. Direct substitution requires no design modifications.

Q: What is the difference between the -15PI and -15PU package designations?

A: The -PI designation indicates DIP packaging format, while -PU indicates tube packaging. Both contain identical die and electrical specifications. The packaging difference affects only handling, storage, and ordering logistics, not circuit performance.

Q: Why is ATF22V10C-15PI listed as obsolete?

A: Obsolete status indicates Microchip Technology has discontinued production of this specific part number variant. The ATF22V10C-15PU remains in active production, providing continuity of supply for the 22V10 PLD architecture.

Q: Are there RoHS compliance implications when substituting these parts?

A: Yes. The ATF22V10C-15PI is RoHS non-compliant, while ATF22V10C-15PU is ROHS3 compliant. For applications requiring RoHS certification or regulatory compliance, ATF22V10C-15PU is the appropriate selection.

Q: Will programming tools and software work with both part numbers?

A: Yes. Both parts use identical EE PLD programming technology and are compatible with standard ATF22V10 programming equipment and software. DiGi-Electronics verification status confirms programmability for ATF22V10C-15PU.
