Z8018010FSG Equivalent & Substitute Parts

Part Overview

The Z8018010FSG is a Z80180 microprocessor IC manufactured by Zilog, featuring 1 core, 8-bit architecture operating at 10MHz in an 80-QFP surface mount package. This part is classified as "Not For New Designs," indicating it has reached end-of-life status. The Z80180 series provides DRAM controllers and additional interfaces including ASCI, CSIO, and UART functionality, operating at 5.0V I/O voltage across a 0°C to 70°C temperature range.

Due to its obsolescence status, identifying equivalent substitute parts is essential for legacy system maintenance, repair, and continued production support where Z80180-based designs remain in operation.

Substitute Part Grouping Explanation

Substitution eligibility for the Z8018010FSG is determined by strict equivalence across the following parameters:

• Core Processor: Must be Z80180 (identical instruction set and functional compatibility)
• Bus Width: Must be 1 Core, 8-Bit (functional requirement for system integration)
• Operating Speed: Must be 10MHz (timing-critical for system synchronization)
• I/O Voltage: Must be 5.0V (electrical compatibility with host circuitry)
• Package Type: Must be 80-BQFP (physical and electrical pin compatibility)
• Mounting Type: Must be Surface Mount (PCB assembly compatibility)
• Interface Set: Must include ASCI, CSIO, UART (functional requirement for communication protocols)
• RAM Controller: Must support DRAM (memory subsystem compatibility)

The Z8018010FEG meets all substitution criteria. The primary difference is packaging format (Tray vs. unspecified) and extended operating temperature range (-40°C to 100°C vs. 0°C to 70°C), with active product status versus obsolescence.

Parameter Comparison

Engineering Selection Recommendations

The Z8018010FEG is a direct functional equivalent to the Z8018010FSG. Both parts share identical core processor architecture, bus width, operating frequency, I/O voltage, package configuration, and interface specifications. The Z8018010FEG maintains active product status with extended temperature range capability (-40°C to 100°C versus 0°C to 70°C), providing broader operational flexibility for legacy system applications.

Selection between these parts should be based on:

• Availability: Z8018010FEG maintains active inventory status (1020 pcs) versus Z8018010FSG obsolescence status (2770 pcs existing stock)
• Temperature Requirements: Z8018010FEG supports extended operating range suitable for industrial or extreme environment applications
• Compliance: Both parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity ratings

For systems operating within the 0°C to 70°C range, either part provides equivalent functionality. For applications requiring extended temperature operation or long-term supply assurance, Z8018010FEG is the preferred selection.

Frequently Asked Questions (FAQ)

Q: Can Z8018010FEG directly replace Z8018010FSG in existing designs?

A: Yes. Both parts are Z80180 microprocessors with identical core architecture, 8-bit bus width, 10MHz speed, 5.0V I/O voltage, 80-BQFP package, and interface specifications (ASCI, CSIO, UART). Pin-for-pin compatibility is maintained. No circuit modifications are required.

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

A: The primary differences are product status (Z8018010FEG is active; Z8018010FSG is obsolete) and operating temperature range (Z8018010FEG: -40°C to 100°C; Z8018010FSG: 0°C to 70°C). Packaging format differs (Tray vs. unspecified), but electrical and functional specifications are identical.

Q: Are there any compatibility concerns with the extended temperature range of Z8018010FEG?

A: No. Extended temperature range represents enhanced capability. Systems designed for 0°C to 70°C operation remain fully compatible with Z8018010FEG. The part will operate correctly across the original temperature specification and beyond.

Q: Do both parts meet current compliance requirements?

A: Yes. Both Z8018010FSG and Z8018010FEG are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings (MSL 3, 168 hours). Compliance certifications are equivalent.

Q: Which part should be selected for new inventory procurement?

A: Z8018010FEG is recommended. It maintains active product status, ensuring continued availability and supply chain stability. The extended temperature range provides additional operational margin for legacy system support.
