Microchip 2 kB Serial EEPROM 3-Pin SOT-23 Surface Mount Serial 100kHz 11AA02E48T-I/TT

Microchip 11AA02E48T-I/TT is a 2 kB Serial EEPROM designed for efficient data storage with a simplified, low-pin-count communication interface based on Microchip's UNI/O™ Serial Bus.

This device reduces the required microcontroller I/O pins by combining clock and data into a single serial bit stream, requiring only one host microcontroller pin compared to traditional interfaces like I2C.

The 3-pin SOT-23 surface mount package makes it ideal for compact embedded electronics in industrial, commercial, and consumer applications where board space and power consumption are critical.

The EEPROM operates reliably across a wide temperature range of -40°C to 85°C and accommodates supply voltages between 1.8V and 5.5V, offering design flexibility. With a maximum clock frequency of 100 kHz, it delivers adequate data throughput for monitoring, control, and configuration data storage in embedded systems.

The memory organisation of 256 words by 8 bits and a data retention capability of 200 years ensure integrity and longevity of stored information. Its low supply current of 5 mA supports energy-efficient device designs, making it suitable for battery-powered and portable applications.

Memory capacity of 2 kB suitable for small data storage applications. Single-wire UNI/O™ Serial Bus interface reduces microcontroller pin requirements. Compact 3-pin SOT-23 surface mount package for space-constrained designs.

Wide voltage range from 1.8V to 5.5V supports diverse system voltages. Operating temperature -40°C to 85°C for industrial and automotive support. Maximum clock frequency of 100 kHz enables moderate-speed communication. 256 x 8-bit memory organisation with 8 bits per word format.

Data retention of 200 years ensures reliability over long durations. Low supply current of 5 mA optimizes power consumption. Small physical size 3.05 mm x 2.64 mm x 1.12 mm fits compact layouts.

This EEPROM is suited for applications in industrial control systems, instrumentation, consumer electronics, automotive electronics, and other embedded systems requiring non-volatile memory with minimal interfacing and footprint.
