Equivalent & Substitute Parts for 11LC080T-I/TT

Part Overview

The 11LC080T-I/TT is an EEPROM memory integrated circuit manufactured by Microchip Technology, designed for non-volatile data storage applications requiring single-wire interface communication. This 8Kbit EEPROM operates at 100 kHz clock frequency with a memory organization of 1K x 8 bits, packaged in SOT-23-3 surface mount configuration. The device is currently in active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the allowed parameter range.

Substitute Part Grouping Explanation

The 11AA080T-I/TT qualifies as a direct substitute for the 11LC080T-I/TT based on the following substitution criteria:

Matching Parameters:

• Memory Type: Non-Volatile EEPROM
• Memory Size: 8Kbit
• Memory Organization: 1K x 8
• Memory Interface: Single Wire
• Clock Frequency: 100 kHz
• Write Cycle Time: 5ms
• Operating Temperature: -40°C ~ 85°C
• Package Type: SOT-23-3
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Voltage Supply Range Consideration: The 11AA080T-I/TT operates across 1.8V ~ 5.5V, which encompasses the 11LC080T-I/TT range of 2.5V ~ 5.5V. This extended lower voltage specification maintains full compatibility for applications within the original device's voltage window.

Parameter Comparison

Engineering Selection Recommendations

Both the 11LC080T-I/TT and 11AA080T-I/TT are active product status devices with full RoHS3 compliance and REACH unaffected status. Selection between these parts is determined by packaging and supply requirements rather than electrical performance. The 11LC080T-I/TT is supplied in Tape & Reel format, while the 11AA080T-I/TT is available in Cut Tape and Digi-Reel format. The extended voltage supply range of the 11AA080T-I/TT (1.8V ~ 5.5V versus 2.5V ~ 5.5V) provides additional operational flexibility for applications operating at lower supply voltages within the original device's specified range. Both devices maintain identical memory specifications, interface characteristics, and thermal operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the 11AA080T-I/TT replace the 11LC080T-I/TT in existing designs?

A: Yes. Both devices share identical memory capacity (8Kbit), organization (1K x 8), interface type (Single Wire), clock frequency (100 kHz), write cycle time (5ms), operating temperature range (-40°C ~ 85°C), and SOT-23-3 package configuration. The 11AA080T-I/TT operates across an extended voltage range (1.8V ~ 5.5V) that fully encompasses the 11LC080T-I/TT specification window (2.5V ~ 5.5V).

Q: What is the difference in packaging between these parts?

A: The 11LC080T-I/TT is supplied in Tape & Reel (TR) format, while the 11AA080T-I/TT is available in Cut Tape (CT) and Digi-Reel® format. Both formats are suitable for surface mount assembly; selection depends on production volume and equipment compatibility.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance status, REACH unaffected designation, and unlimited moisture sensitivity level (MSL 1). Both are manufactured by Microchip Technology with active product status.

Q: Does the extended voltage range of the 11AA080T-I/TT affect compatibility?

A: No. The extended lower voltage specification (1.8V minimum versus 2.5V minimum) does not affect compatibility. Applications designed for the 11LC080T-I/TT operating within its 2.5V ~ 5.5V window will function identically with the 11AA080T-I/TT.

Q: Are the pin configurations identical?

A: Yes. Both devices use the SOT-23-3 package with identical pin assignments and electrical characteristics for single-wire interface operation.
