93LC76-I/P EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 93LC76-I/P is an 8Kbit EEPROM memory integrated circuit manufactured by Microchip Technology, designed for non-volatile data storage applications requiring Microwire serial interface communication. This device operates across a wide supply voltage range of 2.5V to 6.0V and supports memory organization in either 1K x 8 or 512 x 16 configurations. The component is actively produced and maintains full RoHS3 compliance with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical specifications, memory capacity, interface protocol, and physical packaging are maintained across the product line.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 93LC76-I/P is determined by strict equivalence across the following critical parameters: memory capacity (8Kbit), memory organization (1K x 8 or 512 x 16), serial interface protocol (Microwire), clock frequency (3 MHz), write cycle time (5ms), physical package (8-DIP through-hole), and operating temperature range (-40°C to 85°C). The supply voltage range represents the primary electrical distinction among qualified substitutes. Parts meeting all other specifications but operating within a narrower voltage window remain functionally compatible in applications where the reduced voltage range is acceptable. RoHS3 compliance and MSL 1 rating are maintained across all substitute candidates.

Parameter Comparison

Engineering Selection Recommendations

The 93LC76C-I/P qualifies as a direct substitute for the 93LC76-I/P in applications where the supply voltage requirement does not exceed 5.5V. Both parts are manufactured by Microchip Technology, maintain active product status, and carry identical RoHS3 and REACH compliance certifications. The 93LC76C-I/P operates within a narrower voltage specification (2.5V to 5.5V versus 2.5V to 6.0V), making it suitable for standard logic-level supply systems. Selection between these parts depends solely on the maximum supply voltage requirement of the target application circuit. Both devices are programmable and suitable for production environments requiring non-volatile memory with Microwire interface capability.

Frequently Asked Questions (FAQ)

Q: Can the 93LC76C-I/P replace the 93LC76-I/P in all applications?

A: The 93LC76C-I/P is compatible with applications where the supply voltage does not exceed 5.5V. If your circuit requires operation at voltages between 5.5V and 6.0V, the 93LC76-I/P is required. For standard 5V logic systems, both parts are interchangeable.

Q: Are the memory capacities identical between these parts?

A: Yes. Both the 93LC76-I/P and 93LC76C-I/P provide 8Kbit storage capacity with identical memory organization options (1K x 8 or 512 x 16) and Microwire interface specifications.

Q: What is the significance of the voltage range difference?

A: The 93LC76-I/P supports extended voltage operation up to 6.0V, while the 93LC76C-I/P operates to 5.5V maximum. This difference is the only electrical distinction between the parts. Applications using standard 5V supplies can use either part without modification.

Q: Are both parts available in the same physical package?

A: Yes. Both devices are supplied in 8-DIP (0.300", 7.62mm) through-hole packages with identical pin configurations and mechanical dimensions.

Q: Do these parts have different compliance certifications?

A: No. Both the 93LC76-I/P and 93LC76C-I/P maintain identical RoHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity ratings.
