EEPROM Memory: Microchip 93LC56AT-I/OT Serial 2K Device
In the realm of non-volatile memory solutions, EEPROM (Electrically Erasable Programmable Read-Only Memory) remains a cornerstone technology, enabling data retention without power. Among the many options available, the Microchip 93LC56AT-I/OT stands out as a highly reliable and versatile serial EEPROM device. This 2K-bit memory component is engineered for a wide array of applications, from consumer electronics to industrial systems, where dependable data storage is critical.
The 93LC56AT-I/OT is organized as 256 x 8 or 128 x 16 bits, offering flexibility in data organization to suit different system architectures. It operates across a broad voltage range, typically from 2.5V to 5.5V, making it compatible with both 3.3V and 5V systems. This feature is particularly valuable in modern designs where power supply voltages may vary. The device supports a simple and efficient 3-wire serial interface (CS, SK, DI/DO), enabling easy communication with microcontrollers and other digital systems while minimizing pin count and board space.
One of the key advantages of this EEPROM is its low power consumption. It features a standby current of just 1 µA (max), which is crucial for battery-powered and portable applications. Additionally, it offers a maximum write current of 3 mA, ensuring energy-efficient operations during programming cycles. The memory supports both byte write and page write operations, allowing up to 16 bytes to be written in a single cycle, which enhances write efficiency and reduces overall programming time.

Endurance and data retention are critical for non-volatile memories. The 93LC56AT-I/OT is designed for over 1,000,000 erase/write cycles and can retain data for more than 200 years, underscoring its reliability for long-term use. It also incorporates advanced write protection mechanisms, including software and hardware write protection, to prevent accidental data corruption.
Housed in a space-saving SOT-23-6 package, this device is ideal for compact PCB designs. Its extended industrial temperature range (-40°C to +85°C) ensures stable performance even in harsh environments.
