11LC010T-I/MS

Overview

The Microchip Technology 11LC010T-I/MS is a 1 Kbit Serial Electrically Erasable PROM organized as 128 x 8 bits. It operates within a supply voltage range of 2.5V to 5.5V and supports a maximum serial bus frequency of 100 kHz. The device utilizes the UNI/O single I/O interface protocol, combining clock and data on the SCIO pin via Manchester encoding. It features a 16-byte page-write buffer and self-timed write cycles with a typical duration of 5 ms. The component is housed in an 8-lead MSOP package and is rated for industrial temperature operation from -40°C to +85°C.

Feature Summary

• Supports the patented UNI/O single I/O serial bus protocol using Manchester encoding for combined clock and data transmission.
• Includes built-in hardware protections such as power-on/off data protection, write enable latches, and block write protection capabilities.
• Features Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce during signal transitions.

Applications

• Interfacing with microcontrollers or ASICs requiring low-pin-count non-volatile memory storage.
• Embedded systems needing configuration data retention with minimal I/O resource usage.
• Industrial applications requiring robust noise immunity and reliable data retention over extended periods.

Procurement Notes

Verify that the specific ordering suffix corresponds to the required tape-and-reel packaging format and the industrial temperature grade. Confirm the device address hardwiring matches system bus requirements. Ensure the design accounts for the single I/O interface timing constraints defined in the datasheet.

Selection Notes

Select this part when a single-wire interface is necessary to conserve microcontroller pins. Choose this model over the 11AA series if the application requires a minimum operating voltage of 2.5V rather than 1.8V. Consider the 16-byte page buffer size for write efficiency compared to byte-write only devices.

Part Context

This component belongs to the 11LCXXX family of serial EEPROMs manufactured by Microchip Technology. The family shares common architectural features including the UNI/O interface and similar command sets, differing primarily in memory density and minimum operating voltage specifications between the LC and AA sub-series.

Replacement Considerations

Direct substitutes within the same package and interface include other densities from the 11LC010 family, such as the 11LC010 in PDIP or SOIC packages. Cross-family replacements like the 11AA010 require verification of the lower 1.8V operating voltage compatibility.
