Microchip Technology 93LC56A-I/SN EEPROM

The 93LC56A-I/SN is a 2Kb (256 x 8 or 128 x 16-bit) serial Electrically Erasable Programmable Read-Only Memory (EEPROM) chip, developed by Microchip Technology. This device is specifically designed for advanced, low-power applications that require a small data storage component with a robust serial interface. With its industry-standard 3-wire serial bus, the 93LC56A-I/SN is an excellent choice for a wide range of applications in the automotive, industrial, consumer, and telecommunications markets.

Encased in an 8-pin SOIC (Small Outline Integrated Circuit) package, the 93LC56A-I/SN features a self-timed erase and write cycle, meaning no external erase/write timing is necessary. The device also supports both the ORG pin and software command, allowing the user to select the memory configuration as either 256 bytes (8-bit) or 128 words (16-bit), providing flexibility based on the application requirements.

With an operating voltage range of 2.5V to 5.5V, this EEPROM can perform read and write operations over a broad spectrum of power supplies, making it suitable for battery-powered and low-power devices. Additionally, its wide temperature range from -40°C to +85°C ensures reliable operation under extreme conditions.

Key features of the 93LC56A-I/SN include:

• Low-power CMOS technology
• Self-timed erase and write cycles
• Automatic ERAL before WRAL
• Power-on/off data protection circuitry
• Sequential read function
• 100,000 erase/write cycles guaranteed
• Data retention > 200 years
• ESD protection > 4000V
• Industry-standard 3-wire serial interface
• 8-pin SOIC package

The 93LC56A-I/SN also features write protection by programming the write-enable latch (WEL) and write-protect (WP) pin, ensuring critical data is safeguarded against accidental changes. Its small form factor and high reliability make it a suitable non-volatile memory solution for applications such as calibration data storage, device configuration, and ID storage.

This EEPROM from Microchip Technology is an ideal component for designers looking to enhance their systems with a compact, reliable, and cost-effective non-volatile memory option that is easy to integrate and use in a variety of electronic products.
