MICROCHIP  25AA1024-I/SM  EEPROM, 1 Mbit, 128K x 8bit, 20 MHz, SPI, SOIJ, 8 Pins

Product Overview

The 25AA1024-I/SM is a 1024Kbit serial Electrically Erasable Programmable Read-only Memory (EEPROM) 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.
  • Low-power CMOS technology
  • Electronic signature for device ID
  • Self-timed erase and write cycles
  • 6ms Maximum write cycle time
  • Sector write protection (32kB/sector)
  • Built-in write protection
  • High reliability
  • 7mA at 5.5V Maximum write current
  • 10mA at 5.5V/20MHz Maximum read current
  • 1μA at 2.5V, 85°C (deep power-down) Standby current
ESD sensitive device, take proper precaution while handling the device.
