The Microchip 24LC01BT-E/OT: A Compact Powerhouse for Serial Data Storage

In the realm of embedded systems and electronics design, efficient and reliable non-volatile memory is a fundamental requirement. The Microchip 24LC01BT-E/OT stands out as a quintessential solution, offering 1 Kbit of Electrically Erasable Programmable Read-Only Memory (EEPROM) in an extremely space-efficient package. This memory chip is engineered for applications where board space is at a premium and low-power operation is critical.

As a member of the 24XX series, this device utilizes the ubiquitous I²C (Inter-Integrated Circuit) serial communication protocol. This two-wire interface (comprising Serial Data - SDA and Serial Clock - SCL lines) drastically reduces the number of I/O pins required from a controlling microcontroller, simplifying board layout and minimizing system cost. The 24LC01B supports both standard (100 kHz) and fast (400 kHz) mode operations, providing flexibility for a wide range of application speeds.

A key feature of this EEPROM is its low-power consumption, which makes it exceptionally suitable for battery-powered and portable devices. It boasts a low standby current and active current, ensuring that it has a minimal impact on the overall system's power budget. Furthermore, the memory is organized as 128 x 8 (128 bytes), and it features a page write capability of up to 8 bytes, allowing for more efficient data writes.

The device is designed with exceptional reliability and endurance, capable of supporting over 1 million erase/write cycles. Its data retention period exceeds 200 years, guaranteeing data integrity over the entire lifespan of the product. The 24LC01BT-E/OT is offered in a tiny 5-lead SOT-23 package, which is ideal for ultra-compact designs. It operates across a broad voltage range (1.7V to 5.5V), ensuring compatibility with various logic levels and system voltages.

Housed in a robust SOT-23 package, this EEPROM is built to perform in extended temperature ranges (-40°C to +85°C), catering to industrial and automotive applications beyond standard commercial use cases. Its built-in write-protection scheme safeguards critical data from accidental overwrites.

ICGOOODFIND: The Microchip 24LC01BT-E/OT is an optimal choice for designers seeking a miniature, low-power, and highly reliable serial EEPROM. Its combination of the standard I²C interface, substantial endurance, and wide operating voltage makes it a versatile memory component for countless applications, from consumer electronics to medical devices and industrial control systems.
