93C56C-E/P EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 93C56C-E/P is a 2Kbit EEPROM memory integrated circuit manufactured by Microchip Technology, designed for non-volatile data storage applications requiring Microwire serial interface communication. This component is actively produced and widely used in embedded systems, industrial controllers, and consumer electronics requiring persistent memory at low power consumption.

Substitute parts become necessary due to inventory constraints, supply chain disruptions, or design optimization requirements. The following equivalent components maintain functional compatibility while meeting the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 93C56C-E/P is determined by strict equivalence across the following critical parameters:

• Memory capacity (2Kbit) and organization (256 x 8, 128 x 16)
• Serial interface protocol (Microwire)
• Electrical specifications (4.5V ~ 5.5V supply, -40°C ~ 125°C operating range)
• Physical package (8-DIP through-hole configuration)
• Write cycle time (2ms maximum)

The 93C56-E/P qualifies as a direct substitute based on these criteria. Clock frequency variation (2 MHz vs. 3 MHz) does not prevent substitution, as the lower frequency specification remains compatible with Microwire protocol timing requirements and does not degrade system performance in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 93C56C-E/P and 93C56-E/P are manufactured by Microchip Technology and maintain Active product status. Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for industrial and commercial applications.

The 93C56-E/P operates at 2 MHz clock frequency compared to the 3 MHz specification of the 93C56C-E/P. This reduced clock speed does not compromise functionality in applications where the main part was originally specified, as Microwire protocol timing remains within acceptable margins. Selection between these parts should be based on inventory availability and supply chain requirements rather than performance differentiation.

Frequently Asked Questions (FAQ)

Q: Can the 93C56-E/P directly replace the 93C56C-E/P in existing circuit designs?

A: Yes. Both components share identical memory capacity, organization, interface protocol, electrical specifications, and physical packaging. The 2 MHz clock frequency of the substitute part is compatible with standard Microwire timing requirements.

Q: Are there any pin configuration differences between these parts?

A: No. Both components use the 8-DIP package with identical pin assignments and through-hole mounting specifications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 93C56C-E/P and 93C56-E/P are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: What is the significance of the clock frequency difference?

A: The 93C56-E/P operates at 2 MHz while the 93C56C-E/P operates at 3 MHz. This difference does not prevent substitution, as both frequencies support standard Microwire serial communication protocols used in typical applications.

Q: Are both parts actively manufactured?

A: Yes. Both components maintain Active product status with Microchip Technology, ensuring continued availability and support.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Identical 8-DIP package dimensions and pin configurations allow direct PCB substitution without layout modifications.
