The AT25128B-SSHL is a 128-Kbit Serial Interface Flash Memory device from Microchip (formerly Atmel). It features a Serial Peripheral Interface (SPI) for accessing the memory. This device is designed for a wide range of applications requiring non-volatile memory storage.

Applications

• Storage of configuration data in embedded systems
• Firmware storage
• Data logging
• Consumer electronics
• Industrial control systems

Features

• High-speed SPI Interface: Up to 85 MHz
• Single Supply Voltage: 1.8V to 5.5V
• 128-Kbit (16,384 x 8) organization
• Page Program (up to 256 Bytes)
• Sector Erase (4 KB), Block Erase (64 KB), Chip Erase Operations
• Write Protection: Software controlled
• Low Power Consumption
• Endurance: 100,000 write cycles per page
• Data Retention: 20 years
• Packages: SOIC, TSSOP, and others

Benefits

• Fast data transfer rates via the SPI interface enable quick read and write operations.
• Flexible erase options (sector, block, chip) provide efficient memory management.
• Software write protection prevents accidental data corruption.
• Low power consumption makes it suitable for battery-powered applications.
• Small form factor packages allow for compact designs.
