11LC080T-I/MS

Memory IC Overview

The Microchip Technology 11LC080T-I/MS is an 8 Kbit serial electrically erasable programmable read-only memory (EEPROM) utilizing the UNI/O single I/O bus interface. It features a 1,024 x 8 organization with a 16-byte page write buffer. The device operates within a supply voltage range of 2.5 V to 5.5 V and supports a maximum bit rate of 100 kbps. Designed for industrial applications, it functions between -40°C and +85°C. Key electrical characteristics include a typical active current of 1 mA and a maximum standby current of 1 µA. It offers high reliability with 1,000,000 erase/write cycle endurance and data retention exceeding 200 years.

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 write protection mechanisms such as power-on/off data protection circuitry and a software-controlled write enable latch.
• Features block write protection allowing configuration to protect none, one-quarter, one-half, or the entire memory array.
• Incorporates Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce effects.

Memory IC Applications

• Microcontroller-based systems requiring non-volatile data storage
• Industrial control devices needing reliable parameter logging
• Embedded systems with limited I/O pin availability
• Consumer electronics requiring low-power memory solutions

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm that the device address bits are compatible with the system bus architecture. Ensure that the supply voltage levels in the target application fall within the specified 2.5 V to 5.5 V operational range. Check for any recent product change notifications regarding packaging or material composition updates.

Memory IC Selection Notes

Select this component when a single-wire interface is preferred to conserve microcontroller pins. Consider the 16-byte page buffer for efficient sequential data writing operations. Evaluate the low standby current requirement against system power budgets. Ensure the industrial temperature range meets the environmental conditions of the intended deployment scenario.

Memory IC Part Context

This part belongs to the 11XX family of UNI/O serial EEPROMs from Microchip Technology. The family includes variants with densities ranging from 1 Kbit to 16 Kbit. The 'LC' designation indicates a 2.5 V minimum operating voltage, distinguishing it from 'AA' variants that support lower voltages down to 1.8 V. The 'I' suffix denotes the industrial temperature range specification.

Memory IC Replacement Considerations

Consult official Microchip documentation for direct cross-references. Verify compatibility of the UNI/O protocol if substituting with other single-wire EEPROMs. Ensure equivalent voltage ranges and package dimensions for physical replacement.
