Microchip 93C76T-E/SN EEPROM Equivalent & Substitute Parts

Part Overview

The Microchip 93C76T-E/SN is an 8Kbit EEPROM memory IC utilizing Microwire serial interface protocol. This non-volatile memory device operates at 2 MHz clock frequency with a 10ms write cycle time and is housed in an 8-SOIC surface mount package. The part is currently in active production status and ROHS3 compliant. Equivalent and substitute parts are identified when design requirements necessitate alternative packaging formats, extended voltage ranges, or automotive-grade qualification while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 93C76T-E/SN is determined by strict equivalence across the following critical parameters: 8Kbit memory capacity, 1K x 8 or 512 x 16 organization, Microwire interface protocol, 2 MHz clock frequency, 8-SOIC package geometry, and surface mount mounting type. All identified substitutes maintain these core specifications. Packaging format differences (Tape & Reel versus Tube) do not affect functional compatibility. Voltage supply range extensions and automotive-grade qualifications represent additional capabilities that do not preclude substitution. All substitute parts maintain ROHS3 compliance and identical operating temperature ranges.

Parameter Comparison

Engineering Selection Recommendations

The 93C76-E/SN from Microchip Technology is a direct functional equivalent with identical electrical specifications and verified programmability. This substitute differs only in packaging format (Tube versus Tape & Reel), making it suitable for applications where reel packaging is not required.

The CAV93C76VE-GT3 from onsemi is a manufacturer-recommended substitute with extended voltage supply range (2.5V ~ 5.5V) and AEC-Q100 automotive qualification. This part is appropriate for automotive applications or systems requiring lower voltage operation. The extended voltage range provides design flexibility without compromising compatibility with standard 4.5V ~ 5.5V supply systems. Programmability verification status differs from the main part; design validation may be required for specific programming applications.

All three parts maintain ROHS3 compliance, identical operating temperature ranges, and core memory specifications. Selection should be based on packaging requirements, voltage range needs, and automotive qualification necessity.

Frequently Asked Questions (FAQ)

Q: Can the 93C76-E/SN replace the 93C76T-E/SN in production? A: Yes. Both parts are manufactured by Microchip Technology with identical electrical and functional specifications. The only difference is packaging format: the 93C76-E/SN is supplied in Tube format while the 93C76T-E/SN is supplied in Tape & Reel format. Functional compatibility is complete.

Q: What is the primary advantage of the CAV93C76VE-GT3 substitute? A: The CAV93C76VE-GT3 offers two distinct advantages: extended voltage supply range (2.5V ~ 5.5V versus 4.5V ~ 5.5V) and AEC-Q100 automotive qualification. These features make it suitable for automotive applications and systems operating at lower supply voltages.

Q: Are all substitutes pin-compatible? A: Yes. All three parts use the 8-SOIC package with identical pin configuration and spacing (0.154" width, 3.90mm). Direct PCB substitution is possible without layout modifications.

Q: Does the CAV93C76VE-GT3 require additional testing before use? A: The CAV93C76VE-GT3 is not marked as DiGi-Electronics programmable verified. If your application requires verified programmability status, design validation testing is recommended before production deployment.

Q: What is the significance of ROHS3 compliance for all parts? A: ROHS3 compliance indicates all three parts meet Restriction of Hazardous Substances regulations. This certification is mandatory for most commercial and industrial applications and ensures environmental compliance across all substitute options.

Q: Can the CAV93C76VE-GT3 be used in non-automotive applications? A: Yes. The CAV93C76VE-GT3 meets or exceeds all specifications of the original 93C76T-E/SN. Automotive qualification is an additional capability that does not restrict use in standard industrial or commercial applications.
