AT28C256-25LM/883 Frequently Asked Questions (FAQs)

  • The AT28C256-25LM/883 is rated for operation from -55°C to +125°C, making it suitable for military and aerospace applications.
  • The device should be stored in a dry, cool place, away from direct sunlight and moisture. It should be handled with anti-static precautions, such as using an anti-static wrist strap or mat, to prevent electrostatic discharge damage.
  • The recommended power-up sequence is to apply VCC before applying any signals to the device. This ensures that the internal voltage regulator has time to stabilize before the device is accessed.
  • Yes, the AT28C256-25LM/883 is compatible with 3.3V systems. However, the device's output voltage levels will be 5V, so level translation may be required if the system is not 5V tolerant.
  • The AT28C256-25LM/883 is a 256K x 8-bit EPROM, organized as 256 blocks of 1024 x 8 bits. The device uses a byte-wide architecture, with each byte consisting of 8 bits.
