1Kbit Microwire Serial EEPROM 93C46 SMD SOIC-8

EEPROM Serial 1K, SMD, 93C46, SO88 is a high-performance, 1Kbit (128 x 8bit) electrically erasable programmable read-only memory (EEPROM) from STMicroelectronics. This integrated circuit uses the industry-standard MICROWIRE serial bus, ensuring compatibility with a wide range of microcontrollers and digital systems. The memory array can be flexibly configured either as bytes (x8b) or as words (x16b), providing versatility for different data storage requirements.

This EEPROM operates from a single supply voltage ranging from 2.5V to 5.5V, making it suitable for both 3.3V and 5V systems. It supports a 2MHz clock frequency, enabling fast data transfer. The self-timed programming cycle with auto-erase (5ms) simplifies write operations, while the sequential read operation allows for efficient data retrieval. The device is designed for robustness with enhanced ESD and latch-up behaviour, ensuring reliability in demanding environments.

With more than 1 million write cycles and over 40 years of data retention, this EEPROM offers dependable long-term storage. It operates over an ambient temperature range from -40°C to 85°C, making it ideal for industrial and consumer applications. Packaged in an 8-pin SOIC surface-mount package, it is compact and suitable for automated assembly. This component is widely used in embedded design development, consumer electronics, and portable devices.
