The AT93C46-SC872 is a 1K-bit serial electrically erasable and programmable read-only memory (EEPROM) manufactured by Atmel (now Microchip Technology). It's organized as 64 pages of 16 bits each. This memory is commonly used to store configuration data, settings, and other non-volatile information in a wide range of electronic devices.
Applications:
- Consumer electronics (TVs, set-top boxes, DVD players)
- Industrial equipment (PLCs, motor drives)
- Automotive electronics (ECUs, instrument clusters)
- Medical devices
- Security systems
Features:
- 1K-bit (128 x 8 or 64 x 16) EEPROM
- Serial interface (Microwire)
- Low voltage operation (2.7V to 5.5V)
- Self-timed write cycle
- High reliability
- 1,000,000 erase/write cycles
- 100-year data retention
- 8-lead SOIC package
Benefits:
- Non-volatile storage of critical data
- Easy integration with microcontrollers via serial interface
- Low power consumption
- Reliable data storage over long periods
- Small package size for space-constrained applications
- Cost-effective solution for memory storage
Additional Details:
The AT93C46-SC872 communicates via a 3-wire serial interface (Microwire), making it simple to connect to microcontrollers and other digital devices. The self-timed write cycle eliminates the need for external timing components. The device offers high endurance, capable of withstanding 1,000,000 erase/write cycles, and guarantees data retention for 100 years. It is offered in an 8-lead SOIC (Small Outline Integrated Circuit) package. The operating temperature range is -40°C to +85°C. The Microwire interface consists of a clock input (SK), a data input (DI), and a data output (DO). It is commonly employed for storing small amounts of persistent configuration or calibration data within embedded systems.
