CP80C88Z Equivalent & Substitute Parts

Part Overview

The CP80C88Z is an 80C88 microprocessor IC manufactured by Renesas Electronics Corporation, featuring 1 core with 16-bit architecture operating at 5MHz. The device is packaged in a 40-pin DIP configuration and operates at 5.0V I/O voltage across a temperature range of 0°C to 70°C. This part is classified as obsolete, making identification of suitable substitutes essential for system maintenance, repair, and legacy equipment support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CP80C88Z is determined by the following critical parameters:

• Core Processor: Must be 80C88 architecture
• Number of Cores/Bus Width: Must maintain 1 Core, 16-Bit configuration
• Package / Case: Must be 40-DIP (0.600", 15.24mm) for mechanical and electrical compatibility
• Voltage - I/O: Must operate at 5.0V
• Operating Temperature Range: Must support 0°C ~ 70°C minimum
• Mounting Type: Must be Through Hole

The CP80C88-2Z qualifies as a direct substitute based on these parameters. While the CP80C88-2Z operates at 8MHz (higher than the 5MHz of the CP80C88Z), this represents an upward-compatible speed rating. All other critical parameters remain identical, ensuring functional and physical interchangeability.

Engineering Selection Recommendations

The CP80C88-2Z is the qualified substitute for the CP80C88Z. Selection should be based on the following factors:

• Product Status: The CP80C88-2Z maintains Active status, ensuring continued availability and supply chain reliability compared to the Obsolete CP80C88Z.
• Compliance: Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements.
• Speed Compatibility: The 8MHz operation of the CP80C88-2Z exceeds the 5MHz specification of the CP80C88Z. In systems where the original 5MHz speed is a design constraint, the higher speed rating of the substitute must be evaluated against system timing requirements and signal integrity considerations.
• Physical Interchangeability: Identical 40-DIP packaging and through-hole mounting ensure direct socket compatibility without PCB modifications.

Frequently Asked Questions (FAQ)

Q: Can the CP80C88-2Z directly replace the CP80C88Z without PCB modifications?

A: Yes. Both parts share identical 40-DIP packaging dimensions (0.600", 15.24mm) and through-hole mounting configuration, enabling direct socket substitution without PCB layout changes.

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

A: The CP80C88-2Z operates at 8MHz, while the CP80C88Z operates at 5MHz. All other electrical and mechanical parameters remain identical, including core architecture, bus width, voltage rating, and temperature range.

Q: Why is the CP80C88Z classified as obsolete?

A: The CP80C88Z has reached end-of-life status with Renesas Electronics Corporation. The CP80C88-2Z remains in active production, making it the recommended choice for new designs and legacy system repairs.

Q: Are there any compliance differences between the two parts?

A: No. Both the CP80C88Z and CP80C88-2Z maintain ROHS3 compliance, REACH Unaffected status, and identical moisture sensitivity levels (MSL 1 - Unlimited).

Q: Will the higher speed of the CP80C88-2Z cause compatibility issues?

A: The CP80C88-2Z's 8MHz rating is upward-compatible with systems designed for 5MHz operation. However, system-level timing analysis should be performed to ensure that the higher clock speed does not introduce signal integrity or synchronization issues in the target application.
