Device Overview

Summary

EERAM is an SRAM that doesn't lose its content on a power disruption.  Inside each memory cell, transparent to the user, are nonvolatile transistors that capture the SRAM content and hold it through power loss events. On power restore, the SRAM is reloaded with its last content and SRAM operation can continue.

Additional Features
  • 8,192 x 8 bit Serial SRAM with internal nonvolatile data backup
  • High-Speed SPI Interface: Up to 66MHz with Schmitt trigger inputs for noise suppression
  • Low-Power CMOS Technology: Active current: 5 mA (maximum); Standby current: 500 μA (maximum); Hibernate current: 3 μA (maximum)
  • Cell-Based Nonvolatile Backup mirrors SRAM array cell-for-cell and transfers all data to/from SRAM cells in parallel (all cells at same time)
  • Invisible-to-User Data Transfers: VCC level monitored inside device, SRAM automatically saved on power disrupt, and SRAM automatically restored on VCC return
  • 100,000 Backups Minimum (at 20°C)
  • 100 years retention (at 20°C)
  • Operating Voltage Range: 2.7V-3.6V
  • Temperature Range Industrial (I) -40 to 85ºC, Extended (E) -40 to 125ºC
  • 8-SOIC (150mil wide) package; 8-DFN (2x3mm) package
