Z8018008FSG Equivalent & Substitute Parts

Part Overview

The Z8018008FSG is a Z80180 microprocessor IC manufactured by Zilog, featuring 1 core, 8-bit architecture operating at 8MHz 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 multiple communication interfaces (ASCI, CSIO, UART) suitable for embedded applications requiring legacy processor compatibility. Due to its discontinued design status, identifying functionally equivalent alternatives is essential for system maintenance, repair, and legacy product support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Z8018008FSG is determined by the following critical parameters:

Core Compatibility Requirements:

• Identical Z80180 core processor architecture
• Matching 1 core, 8-bit bus width configuration
• Identical 80-BQFP package and surface mount technology
• Identical 5.0V I/O voltage specification
• Identical ASCI, CSIO, UART interface set
• Identical DRAM controller functionality

Allowable Variation Parameters:

• Operating frequency (speed) may be equal or higher than the original 8MHz specification
• Operating temperature range may be extended (wider range acceptable)
• Product status may differ (Active status preferred for availability)
• Packaging format (Tray vs. other formats) does not affect electrical compatibility

The Z8018010FEG qualifies as a direct substitute based on these criteria, offering identical core architecture, package, voltage, and interfaces while providing higher clock speed (10MHz) and extended temperature range (-40°C ~ 100°C).

Parameter Comparison

Engineering Selection Recommendations

The Z8018010FEG is the qualified substitute for Z8018008FSG applications. Selection rationale is based on the following engineering factors:

Electrical Compatibility: Both parts share identical core processor architecture, I/O voltage (5.0V), package configuration (80-BQFP), and interface specifications (ASCI, CSIO, UART). The 10MHz clock speed of the Z8018010FEG is backward compatible with systems designed for 8MHz operation, as higher frequency processors operate correctly in lower-speed applications.

Thermal Compatibility: The Z8018010FEG operating temperature range (-40°C ~ 100°C) encompasses the original part's range (0°C ~ 70°C), providing superior thermal margin for extended environmental conditions.

Compliance & Availability: The Z8018010FEG maintains ROHS3 compliance and identical MSL rating (3, 168 Hours) as the original part. Its Active product status ensures continued availability and supply chain support, addressing the obsolescence risk of the Not For New Designs Z8018008FSG.

Pin-for-Pin Compatibility: Identical 80-BQFP package and surface mount technology enable direct PCB-level replacement without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can Z8018010FEG directly replace Z8018008FSG on existing PCBs?

A: Yes. Both parts use identical 80-BQFP packages with surface mount technology. Pin assignments, voltage requirements (5.0V), and interface specifications are identical, enabling direct board-level substitution without PCB redesign.

Q: What is the impact of the higher 10MHz clock speed in Z8018010FEG?

A: The Z8018010FEG operates at 10MHz versus the original 8MHz. Higher clock frequency is backward compatible with 8MHz-designed systems. The processor will execute instructions faster, which does not create functional incompatibility. System timing margins may improve.

Q: Are there any compliance or certification differences?

A: Both parts maintain ROHS3 compliance and identical Moisture Sensitivity Level (MSL 3, 168 Hours). REACH status and ECCN classifications are identical. No compliance barriers exist for substitution.

Q: Why is Z8018008FSG marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status and is no longer recommended for new product development. The Z8018010FEG, with Active product status, is the supported alternative for ongoing applications.

Q: Are the ASCI, CSIO, and UART interfaces identical between both parts?

A: Yes. Both Z8018008FSG and Z8018010FEG provide identical ASCI, CSIO, and UART interface configurations. Communication protocol compatibility is maintained.

Q: What is the temperature operating range difference?

A: Z8018008FSG operates 0°C ~ 70°C; Z8018010FEG operates -40°C ~ 100°C. The substitute provides extended low-temperature and high-temperature capability, suitable for broader environmental applications.
