Product Overview

The 25LC1024-E/SM is a 1024kb serial EEPROM Memory with byte-level and page-level serial EEPROM functions. It also features page, sector and chip erase functions typically associated with flash-based products. These functions are not required for byte or page write operations. The memory is accessed via a simple serial peripheral interface (SPI) compatible serial bus. The bus signals required are a clock input (SCK) plus separate data in (SI) and data out (SO) lines. Access to the device is controlled by a chip select (CS) input. Communication to the device can be paused via the hold pin (HOLD). While the device is paused, transitions on its inputs will be ignored, with the exception of chip select allowing the host to service higher priority interrupts.
  • 256-byte page
  • 6ms Maximum write cycle time
  • No page or sector erase required
  • Low-power CMOS technology
  • Electronic signature for device ID
  • Page erase (6ms maximum)
  • Sector erase (10ms maximum)
  • Chip erase (10ms maximum)
  • Sector write protection (32kB/sector) - Protect none, 1/4, 1/2 or all of array
  • Built-in write protection - Power-on/off data protection circuitry
  • 1M Erase/write cycles endurance
  • >200-year Data retention
  • 4000V ESD protection
ESD sensitive device, take proper precaution while handling the device.
