ST93C46CB1 - 1K (64 x 16 or 128 x 8) Serial Microwire EEPROM

The ST93C46CB1 is a compact, high-performance EEPROM (Electrically Erasable Programmable Read-Only Memory) produced by STMicroelectronics. This memory device offers a storage capacity of 1K bits, which can be organized either as 64 words of 16 bits each or 128 words of 8 bits each, depending on the user's requirements. The ST93C46CB1 is designed to deliver a flexible and reliable storage solution for various electronic applications that require non-volatile memory storage.

One of the key features of the ST93C46CB1 is its serial Microwire interface, which ensures simple and efficient integration into a wide range of microcontroller-based systems. The device operates over a supply voltage range of 4.5V to 5.5V, making it suitable for many standard digital circuits and ensuring compatibility with 5V systems.

The ST93C46CB1 boasts a fast access time and low power consumption, which is critical for battery-operated devices. In addition, it supports a write cycle time of 5ms, allowing for quick data updates and minimal system downtime. The EEPROM also includes a write protect feature, ensuring data integrity by preventing accidental data alteration during volatile conditions.

The robustness of the ST93C46CB1 is further enhanced by its ability to withstand up to 1 million write cycles and a data retention period of 40 years. This level of endurance and reliability makes it an excellent choice for applications where data must be preserved over long periods, such as in industrial control systems, medical devices, and consumer electronics.

For ease of implementation, the ST93C46CB1 is available in several package options, including the 8-pin DIP (Dual In-line Package) and SOIC (Small Outline Integrated Circuit), providing flexibility for different design layouts and space constraints.

In summary, the ST93C46CB1 from STMicroelectronics is a versatile and reliable EEPROM solution that offers a balance of performance, power efficiency, and durability, making it a preferred choice for designers looking to incorporate non-volatile memory into their systems.
