ATF22V10C-10PC Equivalent & Substitute Parts

Part Overview

The ATF22V10C-10PC is a 22V10 Programmable Logic Device (PLD) IC manufactured by Microchip Technology, featuring 10 macrocells with 10 nanosecond propagation delay in a 24-pin DIP package. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ATF22V10C-10PC is determined by the following critical parameters:

• Series Compatibility: All substitutes must belong to the 22V10 series to maintain functional equivalence
• Macrocell Count: Minimum 10 macrocells required for logic density compatibility
• Package Specification: 24-DIP (0.300", 7.62mm) package mandatory for mechanical and electrical interface compatibility
• Programmable Type: EE PLD (Electrically Erasable Programmable Logic Device) required for programming methodology compatibility
• Input Voltage: 5V operation required for circuit integration compatibility
• Propagation Delay: Speed ratings of 10 ns or faster are acceptable; slower speeds (15 ns) represent functional substitutes with relaxed timing requirements

The ATF22V10C-10PC has two identified substitutes, both from Microchip Technology's active product line, differing primarily in packaging format and propagation delay specification.

Parameter Comparison

Engineering Selection Recommendations

ATF22V10C-10PU is the primary substitute for the ATF22V10C-10PC. Both devices share identical electrical specifications (10 ns propagation delay, 10 macrocells, 5V operation) and mechanical compatibility (24-DIP package). The ATF22V10C-10PU is an active product with ROHS3 compliance, addressing the obsolescence status of the original component while maintaining timing-critical performance requirements.

ATF22V10C-15PU is a secondary substitute suitable for applications where propagation delay tolerance permits 15 nanosecond operation. This device is also an active product with ROHS3 compliance. Selection of this part is appropriate only when system timing margins accommodate the 5 nanosecond delay increase relative to the original specification.

Both substitutes are available in tube packaging (PU designation) rather than the plastic carrier format (PC) of the original part. This packaging difference does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can ATF22V10C-10PU directly replace ATF22V10C-10PC in existing designs?

A: Yes. Both devices are electrically and mechanically identical, with matching 10 nanosecond propagation delay, 10 macrocell configuration, 5V input voltage, and 24-DIP package specification. The packaging format difference (tube versus plastic carrier) does not affect circuit performance or board-level integration.

Q: What is the timing impact of using ATF22V10C-15PU instead of ATF22V10C-10PC?

A: The ATF22V10C-15PU introduces a 5 nanosecond increase in propagation delay (15 ns versus 10 ns). This substitution is valid only for applications where system timing analysis confirms that this delay increase does not violate critical path requirements or timing specifications.

Q: Are there mechanical compatibility concerns between the original part and substitutes?

A: No. All three devices use the 24-DIP (0.300", 7.62mm) package with through-hole mounting. Pin configuration, spacing, and mechanical envelope are identical, ensuring direct board-level compatibility without layout modifications.

Q: Why is the original ATF22V10C-10PC classified as obsolete?

A: The ATF22V10C-10PC is no longer in active production. The ATF22V10C-10PU and ATF22V10C-15PU represent the current active alternatives from Microchip Technology's product portfolio.

Q: Do the substitute parts meet current regulatory compliance requirements?

A: Yes. Both ATF22V10C-10PU and ATF22V10C-15PU are ROHS3 compliant, addressing modern environmental and regulatory standards. The original ATF22V10C-10PC is RoHS non-compliant, making the substitutes preferable for new designs and compliance-sensitive applications.

Q: What is the difference between the PC and PU packaging designations?

A: PC indicates plastic carrier packaging, while PU indicates tube packaging. Both are standard distribution formats for through-hole components and do not affect electrical performance or circuit integration.
