STMICROELECTRONICS 93C56 2Kbit Serial EEPROM, SOIC-8

The STMICROELECTRONICS 93C56 is a 2Kbit (256K x 8bit) MICROWIRE serial access EEPROM (Electrically Erasable Programmable Memory) supplied in an 8-pin SOIC surface-mount package. This reliable non-volatile memory chip is designed for a wide range of embedded and electronic applications, offering flexible configuration and robust performance.

The memory array can be configured by the user either in bytes (x8b) or in words (x16b), providing design versatility. It operates on a single supply voltage ranging from 2.5V to 5.5V, making it compatible with various logic levels and suitable for portable, battery-powered devices. Communication is handled via the industry-standard MICROWIRE serial bus with a maximum clock frequency of 2MHz.

Key Features & Specifications

• High Endurance: Capable of more than 1 million write cycles, ensuring long-term reliability for frequently updated data.
• Long Data Retention: Guarantees data integrity for more than 40 years, making it ideal for critical parameter storage.
• Efficient Programming: Features a self-timed programming cycle with auto-erase (5ms). Programming instructions can operate on a single byte, a word, or the entire memory array.
• Sequential Read: Supports fast sequential read operations for efficient data access.
• Enhanced Robustness: Offers improved ESD (Electrostatic Discharge) and latch-up behaviour for greater reliability in demanding environments.
• Wide Temperature Range: Operates reliably across an ambient temperature range from -40°C to +85°C, suitable for industrial and automotive applications.

This EEPROM is a fundamental component for storing configuration data, calibration settings, or user preferences in a vast array of electronic products.
