Z8018216FSC Equivalent & Substitute Parts

Part Overview

The Z8018216FSC is a Z80180 Microprocessor IC featuring a single 8-bit core operating at 16MHz in a 100-QFP surface mount package. This embedded processor includes integrated DRAM controllers and multiple communication interfaces (ASCI, CSIO, SCC, UART), designed for legacy embedded systems requiring Z80-compatible architecture.

The Z8018216FSC is classified as obsolete, making substitute parts necessary for ongoing production support, maintenance, and system redesigns. Identifying compatible alternatives ensures design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Z8018216FSC is determined by strict equivalence across the following critical parameters:

• Core Processor Architecture: Z80180 (identical instruction set and functional compatibility)
• Bus Width & Core Count: 1 Core, 8-Bit (functional equivalence)
• Operating Frequency: 16MHz (exact speed match)
• I/O Voltage: 5.0V (electrical compatibility)
• Package Type: 100-QFP (physical and pinout compatibility)
• Interface Set: ASCI, CSIO, SCC, UART (functional feature parity)
• Temperature Range: 0°C ~ 70°C (operational envelope match)

The Z8018216FSG qualifies as a direct substitute based on identical performance specifications and pinout compatibility. Packaging format differences (tray vs. standard) do not affect functional substitution.

Parameter Comparison

Engineering Selection Recommendations

The Z8018216FSG serves as the direct functional equivalent to the Z8018216FSC. Both parts share identical electrical specifications, pinout configuration, and operational characteristics across all critical parameters.

Product Status Consideration: The Z8018216FSC is classified as obsolete, while the Z8018216FSG carries a Last Time Buy status. This distinction indicates that Z8018216FSG represents the final production availability window for this processor family from Zilog.

Compliance Difference: The Z8018216FSG achieves ROHS3 compliance, whereas the Z8018216FSC is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the Z8018216FSG is the appropriate selection. For legacy systems without RoHS mandates, both parts are functionally interchangeable.

Supply Chain: Current inventory shows 1253 units of Z8018216FSG available, compared to 2400 units of Z8018216FSC. For new designs or extended production runs, Z8018216FSG availability should be confirmed with the supplier given its Last Time Buy status.

Frequently Asked Questions (FAQ)

Q: Can Z8018216FSG replace Z8018216FSC in existing designs?

A: Yes. Both parts are electrically and functionally identical. They share the same core processor (Z80180), operating frequency (16MHz), I/O voltage (5.0V), package type (100-QFP), and interface configuration (ASCI, CSIO, SCC, UART). Direct substitution requires no circuit modifications.

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

A: The primary differences are product status and RoHS compliance. Z8018216FSC is obsolete and RoHS non-compliant, while Z8018216FSG is Last Time Buy and ROHS3 compliant. Functionally, they are identical.

Q: Does packaging format affect substitution?

A: No. The Z8018216FSC is supplied in standard packaging, while Z8018216FSG is supplied in tray packaging. Both contain the same die and pinout. Packaging format does not impact electrical or mechanical compatibility.

Q: Are there any temperature or voltage derating considerations?

A: No. Both parts operate within the identical temperature range (0°C ~ 70°C) and I/O voltage specification (5.0V). No derating or thermal management adjustments are required when substituting between these parts.

Q: What is the MSL rating for these parts?

A: Both parts carry MSL 3 (168 Hours). Standard moisture control procedures during storage and handling apply equally to both variants.

Q: Should I prioritize one part over the other for new designs?

A: For new designs, Z8018216FSG is the appropriate choice due to its Last Time Buy status and ROHS3 compliance. However, verify current availability with your supplier, as Last Time Buy status indicates limited future production windows.
