Differing Parameters:

• Supply voltage range: 93LC76/P operates 2.5V ~ 6.0V; 93LC76C-I/P operates 2.5V ~ 5.5V
• Operating temperature range: 93LC76/P operates 0°C ~ 70°C; 93LC76C-I/P operates -40°C ~ 85°C

Parameter Comparison

Engineering Selection Recommendations

Both the 93LC76/P and 93LC76C-I/P are active production devices from Microchip Technology with ROHS3 compliance. Selection between these parts depends on application requirements:

Select 93LC76/P when:

• Operating voltage exceeds 5.5V (up to 6.0V maximum)
• Operating temperature range is limited to 0°C ~ 70°C
• Standard industrial temperature specifications are sufficient

Select 93LC76C-I/P when:

• Extended temperature range operation is required (-40°C ~ 85°C)
• Supply voltage remains within 2.5V ~ 5.5V
• Military, aerospace, or automotive environmental specifications apply

Both parts maintain identical memory capacity, interface protocol, and package form factor, ensuring direct pin-compatible substitution within the specified electrical operating ranges.

Frequently Asked Questions (FAQ)

Q: Are the 93LC76/P and 93LC76C-I/P pin-compatible?

A: Yes. Both devices use the 8-DIP (0.300", 7.62mm) package with identical pinout. Direct substitution is possible without PCB modifications.

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

A: The 93LC76C-I/P supports extended operating temperature range (-40°C ~ 85°C) and reduced maximum supply voltage (5.5V vs 6.0V) compared to the 93LC76/P (0°C ~ 70°C, 2.5V ~ 6.0V).

Q: Can I use 93LC76C-I/P in an application designed for 93LC76/P?

A: Substitution is valid only if your application operates within the 93LC76C-I/P specifications: supply voltage 2.5V ~ 5.5V and temperature -40°C ~ 85°C. If your design requires 6.0V operation, the 93LC76/P is required.

Q: Do both parts support the same Microwire protocol?

A: Yes. Both devices implement identical Microwire serial interface at 3 MHz clock frequency with 5ms write cycle time.

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant with REACH unaffected status. No compliance differentiation exists between the two devices.
