Z8S18010FSC Equivalent & Substitute Parts

Part Overview

The Z8S18010FSC is a Z180 microprocessor IC manufactured by Zilog, featuring an 8-bit core operating at 10MHz in an 80-QFP surface mount package. This component is classified as obsolete, with 943 units currently in stock. The Z180 series is a single-core, 8-bit embedded processor designed for legacy embedded systems requiring DRAM control and serial communication interfaces (ASCI, CSIO, UART). Due to its obsolete status, identifying equivalent substitute parts is essential for system maintenance, repair, and component sourcing continuity.

Substitute Part Grouping Explanation

Substitution of the Z8S18010FSC is determined by strict equivalence across the following critical parameters:

• Core Processor Architecture: Z8S180 (identical processor core)
• Clock Speed: 10MHz (exact frequency match)
• Bus Width: 1 Core, 8-Bit (identical configuration)
• Package Type: 80-BQFP (identical physical form factor)
• Mounting Technology: Surface Mount (identical mounting method)
• Voltage Rating: 5.0V I/O (identical electrical specification)
• Operating Temperature Range: 0°C ~ 70°C (identical thermal specification)
• Interface Set: ASCI, CSIO, UART (identical communication interfaces)

The Z8S18010FSG qualifies as a direct substitute based on complete alignment with all critical electrical and mechanical parameters. The primary distinction is product status and packaging format, not functional capability.

Parameter Comparison

Engineering Selection Recommendations

The Z8S18010FSG is a direct functional equivalent to the Z8S18010FSC. Both components share identical electrical specifications, processor architecture, clock frequency, package geometry, and interface configuration. Selection between these parts should be based on the following criteria:

Z8S18010FSC: Use only when legacy component matching is required for existing inventory or when RoHS non-compliance is acceptable for the application. Product status is obsolete; availability may become constrained.

Z8S18010FSG: Preferred for new designs, system repairs, and applications requiring regulatory compliance. This part maintains active product status with ROHS3 compliance certification, ensuring continued availability and meeting modern environmental standards. Packaging format is tray-based, suitable for production environments.

Both parts are functionally interchangeable at the circuit level. No design modifications are required when transitioning between these part numbers.

Frequently Asked Questions (FAQ)

Q: Can Z8S18010FSG replace Z8S18010FSC in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The Z8S18010FSG can be used as a direct replacement without circuit modifications or firmware changes.

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

A: The primary differences are product status (obsolete vs. active) and RoHS compliance certification. The Z8S18010FSG is ROHS3 compliant, while the Z8S18010FSC is not. Functionally, both parts are equivalent.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 80-BQFP surface mount package with identical pin configuration, pitch, and physical dimensions. PCB footprints are interchangeable.

Q: What is the significance of the packaging format difference (tray vs. other)?

A: Packaging format affects handling and storage but does not impact electrical performance. Tray packaging (Z8S18010FSG) is standard for production environments and automated assembly processes.

Q: Is the Z8S18010FSG suitable for new product designs?

A: Yes. The active product status and ROHS3 compliance make the Z8S18010FSG appropriate for new designs. The Z180 series remains available through Zilog for legacy system support and maintenance applications.

Q: Do these parts require different handling or storage procedures?

A: Both parts have identical moisture sensitivity levels (MSL 3, 168 hours). Storage and handling procedures are the same.
