Product Overview: M93C56

The M93C56 is a 4Kbit (512 x 8 or 256 x 16) serial EEPROM device from STMicroelectronics, designed for use in a wide array of electronic devices and embedded systems. This EEPROM (Electrically Erasable Programmable Read-Only Memory) provides robust, non-volatile memory storage, which means that it retains data even when the power is turned off, making it ideal for applications that require data persistence.

Key Features

• Memory Size: 4Kbit, organized as either 512 bytes (x8) or 256 words (x16), selectable through an external instruction.
• Serial Interface: Accessible through a 2-wire serial interface, supporting the I<sup>2C bus protocol, which simplifies integration into most microcontroller-based systems.
• Write Cycle Time: Efficient write operations with a typical write cycle time of 5ms, ensuring quick data storage and updates.
• Wide Voltage Range: Operates across a voltage range of 2.5V to 5.5V, allowing for flexibility in various power supply conditions.
• High Reliability: Endurance of 1 million write cycles and a data retention period of 40 years, guaranteeing long-term reliability for critical data storage.
• Temperature Range: Industrial temperature range from -40°C to 85°C, suitable for operation in harsh environmental conditions.

Applications

The M93C56 EEPROM is used across various applications that require data storage or configuration settings that must be preserved during power loss. Common applications include:

• Automotive systems
• Industrial control systems
• Medical devices
• Smart meters
• Consumer electronics
• Portable devices

Availability

The M93C56 is available in multiple package options, including SO8, TSSOP8, UFDFPN8 (MLP8), and WLCSP, providing designers with the flexibility to choose the best fit for their design requirements.
