Microchip 1 kB Serial EEPROM with 3-Pin SOT-23 Package 11AA010T-I/TT

Microchip 11AA010T-I/TT is a 1 kB Serial EEPROM designed with a 3-pin SOT-23 surface mount package, providing efficient serial memory storage for embedded and industrial electronics applications.

This EEPROM utilizes Microchip’s UNI/O™ Serial Bus technology that combines clock and data signals into a single bit stream, reducing the number of microcontroller I/Os required, thereby minimizing host microcontroller complexity and cost.

The device operates within a voltage range from 1.8 V minimum supply voltage to 5.5 V maximum, supporting a wide variety of power environments. It supports a maximum clock frequency of 100 kHz for serial communication, making it suitable for moderate-speed data access scenarios.

Physically, the EEPROM comes in a small 3-pin SOT-23 package sized at 3.05 mm in length, 2.64 mm width, and 1.12 mm height, ideal for applications with strict space constraints such as compact consumer electronics, automotive auxiliary systems (non-automotive compliant), and industrial controllers.

Its operating temperature range from -40°C to 85°C ensures reliability in harsh environments. The data retention capability of 200 years ensures long-term data preservation even in power-off states. The device consumes a low supply current of 5 mA, supporting energy-efficient embedded designs.

This serial EEPROM is widely employed in electronics industries like industrial automation, communications, embedded control systems, and general semiconductor applications. The device features Microchip’s proprietary UNI/O™ Serial Bus requiring only one I/O pin for clock and data.

It has a memory size of 1 kilobyte organized as 1K x 8 bits supporting 128 words. Operates over a voltage range of 1.8V to 5.5V, suitable for low-voltage applications. Maximum clock frequency of 100 kHz ensures reliable serial communication.

The compact 3-pin SOT-23 package measures 3.05 mm length, 2.64 mm width, and 1.12 mm height. Designed for industrial operating temperature range from -40°C to 85°C. Data retention is guaranteed for up to 200 years, ensuring long-term reliability.

Supply current is low at 5 mA, optimizing power usage in embedded systems. Surface mount type with 3 pins is ideal for compact and automated PCB assembly.
