11AA080T-I/SN

Overview

The Microchip Technology 11AA080T-I/SN 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 k x 8 organization and operates within a supply voltage range of 1.8 V to 5.5 V. The device supports a maximum bit rate of 100 kbps and includes a 16-byte page-write buffer. It is housed in an SOIC-8 surface-mount package, rated for industrial temperatures from -40°C to +85°C, and supplied in tape-and-reel packaging.

Feature Summary

• Supports the patented UNI/O single I/O serial bus protocol using Manchester encoding on the SCIO pin
• Includes built-in write protection with power-on/off data protection circuitry and block write protection capabilities
• Features Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce
• Provides high reliability with one million erase/write cycle endurance and over 200 years of data retention

Applications

• Microcontroller system configuration storage
• Calibration data and parameter logging
• Low-pin-count embedded device memory
• Industrial sensor data recording

Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the presence of the 'T' designation indicates tape-and-reel packaging rather than tube or cut tape. Ensure the 'I' suffix corresponds to the industrial temperature range requirements for your application environment before finalizing procurement orders.

Selection Notes

Select this component when a microcontroller requires non-volatile storage with minimal pin usage. The UNI/O interface reduces PCB trace count compared to standard SPI or I2C devices. Verify that the host controller software can implement the Manchester encoding protocol required for communication with the SCIO pin.
