Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATF16V8C-7PI is determined by strict equivalence across the following critical parameters:

• Macrocell Count: 8 macrocells (functional logic capacity)
• Speed Grade: 7.5 ns propagation delay (timing performance)
• Programmable Type: EE PLD (electrically erasable, field-programmable)
• Voltage Rating: 5V input operation
• Package: 20-PDIP through-hole configuration
• Manufacturer: Microchip Technology (same design family)

The ATF16V8C-7PU qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status and packaging format, with the -7PU variant currently in active production.

Parameter Comparison

Engineering Selection Recommendations

The ATF16V8C-7PU is the direct functional equivalent for the obsolete ATF16V8C-7PI. Selection between these parts is determined by regulatory and compliance requirements:

ATF16V8C-7PU is the preferred choice for new designs and production systems requiring:

• Active product status with ongoing manufacturer support
• ROHS3 compliance for regulated markets and applications
• Current availability through distribution channels
• Identical electrical and timing performance

ATF16V8C-7PI remains suitable for legacy system maintenance and repair applications where:

• Existing inventory is available
• RoHS compliance is not a requirement
• Direct pin-for-pin replacement is needed in established designs

Both parts share identical electrical specifications, timing characteristics, and physical package dimensions, ensuring functional interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can ATF16V8C-7PU directly replace ATF16V8C-7PI in existing designs?

A: Yes. Both parts are electrically and mechanically identical, with 8 macrocells, 7.5 ns speed, 5V operation, and 20-PDIP through-hole packaging. No circuit modifications are required.

Q: What is the primary difference between these two part numbers?

A: The ATF16V8C-7PU is the active production variant with ROHS3 compliance, while the ATF16V8C-7PI is obsolete and RoHS non-compliant. Electrical performance and package configuration are identical.

Q: Are there any timing or functional differences between the -7PI and -7PU variants?

A: No. Both variants maintain 7.5 ns propagation delay and identical macrocell architecture. Substitution does not affect circuit timing or logic functionality.

Q: What packaging formats are available for these parts?

A: Both the ATF16V8C-7PI and ATF16V8C-7PU are supplied in tube packaging in 20-PDIP through-hole configuration.

Q: Is the ATF16V8C-7PU suitable for new product designs?

A: Yes. The ATF16V8C-7PU is the recommended choice for new designs due to active product status, ROHS3 compliance, and ongoing manufacturer support.
