11LC080T-I/MNY

Memory IC Overview

The Microchip Technology 11LC080T-I/MNY is an 8 Kbit (1,024 x 8) serial EEPROM utilizing the UNI/O single I/O bus interface. It operates within a voltage range of 2.5 V to 5.5 V and supports a maximum bit rate of 100 kbps. The device features a 16-byte page-write buffer and includes block write protection capabilities. It is housed in a 3-lead SOT-23 package and is rated for industrial temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Supports the patented UNI/O single I/O serial bus protocol using Manchester encoding for clock and data transmission on a single pin.
• Includes built-in power-on/off data protection circuitry and a write enable latch to prevent accidental writes.
• Features a 16-byte page-write buffer to optimize write performance and reduce internal write cycle time.

Memory IC Applications

• Microcontroller system configuration storage
• Calibration data retention in embedded devices
• Parameter logging in low-pin-count sensors

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and package type. Confirm that the design utilizes a microcontroller or ASIC capable of generating the proprietary UNI/O Manchester encoded protocol. Ensure the supply voltage remains within the specified 2.5 V to 5.5 V operational range for reliable function.

Memory IC Selection Notes

Select this component when a single I/O interface is required to minimize pin count compared to standard SPI or I2C memories. It is suitable for applications where moderate speed is acceptable but board space is constrained. Consider the 11AA080 variant if operation below 2.5 V is necessary, as the 11LC series requires a minimum of 2.5 V.

Memory IC Part Context

This part belongs to the 11XX family of Serial Electrically Erasable PROMs from Microchip Technology. The family ranges from 1 Kbit to 16 Kbit densities and supports both UNI/O and 1-Wire interfaces depending on the specific model prefix. The 11LC series specifically denotes the UNI/O interface variant with a 2.5 V minimum operating voltage.

Memory IC Replacement Considerations

The 11AA080T-I/MNY serves as a compatible alternative within the same package, offering identical functionality with a lower 1.8 V minimum operating voltage. Other density variants such as the 11LC040 or 11LC160 may be considered if memory capacity requirements differ while maintaining the same interface and package constraints.
