Overview
The Microchip Technology 11AA160T-I/TT is a 16 Kbit serial EEPROM utilizing the UNI/O single-wire interface. It features a 2,048 x 8 bit organization with a 16-byte page write buffer. Operating voltages range from 1.8 V to 5.5 V, supporting industrial temperature ranges of -40°C to +85°C. The device includes Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce. It offers high reliability with 1,000,000 erase/write cycles and data retention exceeding 200 years.
Feature Summary
- Supports the patented UNI/O single I/O serial bus protocol using Manchester encoding.
- Includes built-in write protection via power-on/off circuitry and a write enable latch.
- Features block write protection allowing configuration of none, 1/4, 1/2, or all array segments.
- Provides self-timed write cycles with automatic erase capabilities.
Applications
- Microcontroller system memory
- ASIC data storage
- Discrete I/O line interfacing
Procurement Notes
Verify the specific suffix 'TT' corresponds to the SOT-23-3 package and reel packaging format as documented in the datasheet. Confirm that the 'I' designation matches the required industrial temperature range specifications for your application environment.
Selection Notes
Select this component when a low-pin-count solution is required for non-volatile data storage. The UNI/O interface minimizes pin usage compared to standard SPI or I2C devices. Ensure the master controller supports the specific Manchester encoding timing requirements defined in the protocol specification.
Part Context
This part belongs to the 11AAXXX/11LCXXX family of serial EEPROMs. The 'AA' prefix indicates support for low-voltage operation down to 1.8 V, distinguishing it from the 'LC' series which requires a minimum of 2.5 V. Both series share identical functional interfaces and physical package options.
Replacement Considerations
Compatible substitutes within the same family include the 11AA160T-I/MNY (TDFN-8 package) and the 11AA160-I/SN (SOIC-8 package). These parts maintain electrical compatibility but differ in physical footprint and mounting style.
