ST93C56B6 - EEPROM by STMicroelectronics

The ST93C56B6 is a robust, high-performance EEPROM (Electrically Erasable Programmable Read-Only Memory) chip developed by STMicroelectronics. This memory device provides a storage capacity of 4 Kbit, organized as 256 x 16 bits in the word mode or 512 x 8 bits in the byte mode, which can be selected through the instruction set. It is designed for applications that require data to be stored and retrieved even after power is turned off, making it ideal for a wide range of industrial, automotive, and consumer electronics.

The ST93C56B6 operates over a wide voltage range of 4.5V to 5.5V and features a fast access time, which is critical for high-speed microcontroller-based systems. The device supports a serial I²C bus interface, facilitating easy integration into existing designs with minimal additional components required.

One of the key features of the ST93C56B6 is its high reliability and endurance, with the EEPROM cells capable of withstanding up to 1 million erase/write cycles and a data retention period of 40 years, ensuring the safety and longevity of critical data. Additionally, the device includes a Write Control instruction that enables the hardware protection of the entire memory array, preventing accidental data corruption.

The ST93C56B6 is available in a variety of packages, including the compact SO8N and TSSOP8, which are suitable for space-constrained applications. Its low power consumption in both active and standby modes makes it an energy-efficient choice for battery-operated devices.

In summary, the ST93C56B6 from STMicroelectronics is a versatile and reliable EEPROM solution that provides secure data storage for applications requiring frequent or long-term data retention. Its compatibility with serial communication protocols, coupled with its robust endurance and data retention capabilities, makes it a preferred choice for designers and engineers across various industries.
