Microchip 2 kB Serial EEPROM 3-Pin SOT-23 Serial Interface 100kHz Clock 1.8V-5.5V 11AA02E48T-I/TT

Microchip 11AA02E48T-I/TT is a 2 kB serial EEPROM designed with a 3-pin SOT-23 package, featuring Microchip's proprietary UNI/O™ Serial Bus interface. This interface simplifies communication by combining clock and data signals into a single serial bit stream, allowing operation with only one microcontroller I/O pin.

Operating at a maximum clock frequency of 100kHz with a voltage supply ranging from 1.8V to 5.5V, this EEPROM offers flexibility for a variety of low-power embedded applications. The memory is organised as 256 words of 8 bits each, providing 2 kB storage capacity with 200 years data retention, ensuring reliable long-term data storage.

The device is built to function within a temperature range of -40°C to 85°C, making it suitable for many industrial, automotive, and commercial electronics environments. The low supply current of 5 mA supports power-conscious designs.

With a compact height of 1.12mm, length of 3.05mm, and width of 2.64mm in a surface mount SOT-23 package, it is ideal for space-constrained PCBs.

Uniquely, the UNI/O™ protocol requires only one microcontroller I/O instead of multiple lines typical of I2C or SPI buses, reducing system complexity and lowering costs while enabling more compact designs.

This EEPROM is typically employed in various electronic components and semiconductor-based memory chip applications, providing efficient, reliable, and long-life non-volatile memory solutions.

This EEPROM uses Microchips proprietary UNI/O™ Serial Bus requiring only one microcontroller I/O. It features 2 kB memory size organised as 256 x 8 bits. The device is housed in a compact 3-pin SOT-23 package suitable for surface mount technology.

Operates over a temperature range of -40°C to 85°C to suit various industrial applications. Data retention is specified up to 200 years ensuring long-term reliability. Supply current is low at 5 mA enhancing power efficiency in embedded systems.

The device offers ease of integration with high-speed data transmission at 100kHz clock rate. Dimensions are height 1.12mm, length 3.05mm, and width 2.64mm for compact PCB footprint. Ideal for use in electronic components, semiconductors, and memory chip applications.
