ATF16V8C-5XC Equivalent & Substitute Parts

Part Overview

The ATF16V8C-5XC is a 16V8 Programmable Logic Device (PLD) IC manufactured by Microchip Technology, featuring 8 macrocells and 5 ns propagation delay in a 20-TSSOP surface mount package. This device is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations. The ATF16V8C-5XC operates at 5V input voltage and is designed for applications requiring programmable logic functionality with fast switching characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ATF16V8C-5XC is determined by the following critical parameters:

• Series Compatibility: Both main and substitute parts must belong to the 16V8 series
• Macrocell Count: Substitute must provide 8 macrocells minimum
• Programmable Type: EE PLD (Electrically Erasable Programmable Logic Device) type must be maintained
• Input Voltage: 5V operation requirement must be supported
• Package / Case: 20-TSSOP package with identical physical dimensions (0.173", 4.40mm Width)
• Mounting Type: Surface mount configuration must be preserved

The ATF16V8CZ-15XU qualifies as a direct substitute based on these parameters. While the speed specification differs (15 ns versus 5 ns), this represents a relaxed timing characteristic that does not prevent functional substitution in applications where the original 5 ns specification was not a critical design constraint.

Parameter Comparison

Engineering Selection Recommendations

The ATF16V8CZ-15XU is the qualified substitute for the obsolete ATF16V8C-5XC. Selection of this substitute is supported by the following factors:

Product Status: The ATF16V8CZ-15XU maintains active product status with Microchip Technology, ensuring continued availability and manufacturing support compared to the obsolete ATF16V8C-5XC.

Compliance: The ATF16V8CZ-15XU achieves ROHS3 compliance and carries EAR99 ECCN classification, providing improved regulatory alignment for new designs and procurement cycles.

Functional Equivalence: Both devices share identical macrocell count, input voltage specification, package configuration, and programmable logic architecture, ensuring pin-compatible and functionally equivalent operation within the 16V8 series framework.

Speed Consideration: The 15 ns speed specification of the ATF16V8CZ-15XU represents a relaxed timing parameter relative to the 5 ns ATF16V8C-5XC. Component selection should verify that system timing requirements do not mandate the faster 5 ns specification.

Frequently Asked Questions (FAQ)

Q: Can the ATF16V8CZ-15XU directly replace the ATF16V8C-5XC in existing designs?

A: Yes, the ATF16V8CZ-15XU provides direct pin-compatible and functionally equivalent replacement. Both devices use the 20-TSSOP package with identical physical dimensions and pinout. Verification that system timing margins accommodate the 15 ns speed specification is required.

Q: What is the primary difference between these two parts?

A: The primary difference is propagation delay speed: ATF16V8C-5XC operates at 5 ns while ATF16V8CZ-15XU operates at 15 ns. Both devices are electrically erasable programmable logic devices with 8 macrocells operating at 5V.

Q: Why is the ATF16V8C-5XC listed as obsolete?

A: The ATF16V8C-5XC has been discontinued by Microchip Technology. The ATF16V8CZ-15XU remains in active production and is the recommended substitute for new designs and replacement applications.

Q: Are there packaging differences between these parts?

A: Both parts use 20-TSSOP surface mount packaging with identical dimensions (0.173", 4.40mm Width). The ATF16V8CZ-15XU is supplied in tube packaging, while the ATF16V8C-5XC packaging specification was not provided.

Q: What compliance certifications apply to the substitute part?

A: The ATF16V8CZ-15XU is ROHS3 compliant and classified under ECCN EAR99. The original ATF16V8C-5XC is RoHS non-compliant and classified under ECCN 3A991D.
