11LC010-E/P

Overview

The Microchip Technology 11LC010-E/P is a 1 Kbit (128 x 8) serial electrically erasable PROM utilizing the UNI/O single I/O bus interface. It operates within a supply 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, self-timed write cycles, and block write protection capabilities. It is housed in an 8-lead PDIP package and is rated for an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Supports the patented UNI/O single I/O serial bus protocol using Manchester encoding on the SCIO pin.

Applications

• Microcontroller system memory
• ASIC data storage
• Discrete I/O line configuration

Procurement Notes

Verify that the ordering suffix 'E' corresponds to the Automotive temperature grade (-40°C to +125°C) as specified in the datasheet selection table. Confirm the 'P' suffix indicates the 8-lead PDIP package type. Ensure the component matches the 11LC010 density and UNI/O interface before integration.

Selection Notes

Select this part when a low-pin-count serial EEPROM is required for applications needing extended temperature operation up to 125°C. The UNI/O interface minimizes microcontroller I/O usage compared to standard SPI or I2C protocols. Verify that the 1 Kbit capacity and 2.5 V minimum operating voltage align with the system power architecture.

Part Context

This component belongs to the 11XX family of serial EEPROMs manufactured by Microchip Technology. The family includes variants with densities ranging from 1 Kbit to 16 Kbit. The 11LC series specifically denotes devices operating with a minimum supply voltage of 2.5 V, distinguishing them from the 11AA series which supports lower voltages down to 1.8 V.

FAQ

How does the UNI/O interface manage clock and data signals?

The UNI/O interface combines the clock and data into a single serial bit stream (SCIO) using Manchester encoding techniques, allowing the receiver to extract the clock signal to decode timing and values.

What mechanism protects data during power transitions?

The device includes built-in power-on/off data protection circuitry and a write enable latch to prevent unintended writes during power fluctuations.
