47L04T-E/ST - High-Performance 4Kbit I2C Serial EERAM by Microchip Technology

The 47L04T-E/ST is a cutting-edge 4Kbit I2C Serial EERAM (Electrically Erasable Random Access Memory) from Microchip Technology, combining the fast write speeds of SRAM with the non-volatile storage capabilities of EEPROM. This innovative memory solution is ideal for applications requiring frequent data updates with automatic backup protection.

Key Features & Benefits:

  • Dual Technology: SRAM performance with EEPROM non-volatility for optimal data integrity
  • Fast Access: 400ns access time with 1MHz I2C clock frequency for rapid data operations
  • Reliable Storage: 4Kbit (512 x 8) memory organization with automatic EEPROM backup
  • Wide Operating Range: Functions reliably from -40°C to 125°C in industrial environments
  • Low Power: 2.7V to 3.6V supply voltage for energy-efficient operation
  • Space-Saving: Compact 8-TSSOP surface mount package (4.40mm width)
  • RoHS Compliant: Environmentally friendly and meets international standards

Ideal Applications:

Perfect for industrial automation, automotive systems, medical devices, data logging, configuration storage, and any application requiring frequent write operations with power-loss protection.
