Microchip 93AA86C-I/SN 7V 16Kb Microwire Serial EEPROM for Data Storage Applications

In the realm of embedded systems and electronic design, reliable non-volatile memory is a cornerstone for storing critical parameters, configuration data, and event logs. The Microchip 93AA86C-I/SN stands out as a robust and efficient solution, specifically engineered to meet these demanding data storage needs. This 16Kbit Microwire Serial EEPROM combines high performance with exceptional reliability, making it a preferred choice for a wide array of applications.

Operating from a single 7V power supply, this memory IC offers a substantial storage capacity of 16 kilobits (2048 x 8 or 1024 x 16), organized in a flexible architecture that supports both 8-bit and 16-bit instruction sets. The device utilizes the simple and efficient 3-wire Microwire serial interface, which requires only a Chip Select (CS), Serial Clock (SK), and Data Input/Output (DI/DO) line for communication. This simplicity reduces the number of GPIO pins required from the host microcontroller, simplifying board layout and lowering overall system cost.

A key feature of the 93AA86C is its robust read/write endurance and data retention. It supports a minimum of 1 million erase/write cycles per cell and guarantees data retention for over 200 years, ensuring data integrity even in the most demanding industrial environments. Furthermore, it incorporates advanced write-protection mechanisms. An onboard memory write protect feature can be enabled via software commands or by driving the ORG pin to a specific state, safeguarding stored data from accidental or malicious corruption.

The 93AA86C-I/SN is offered in the compact 8-lead SOIC (SN) package, making it suitable for space-constrained applications. Its industrial temperature range (-40°C to +85°C) ensures stable operation across harsh environmental conditions. Typical applications are extensive, including:

Automotive electronics for storing mileage, VIN, and calibration data.

Industrial control systems for parameter storage and event logging.

Consumer appliances and smart meters for configuration settings.

Medical devices requiring secure and reliable data storage.
