AM29F040B-90JI Frequently Asked Questions (FAQs)

  • The AM29F040B-90JI has a minimum of 100,000 erase cycles per sector, and a minimum of 10,000 erase cycles per block.
  • The HOLD# signal should be kept high during power-up and power-down to prevent unwanted writes or erases. It's recommended to tie HOLD# to VCC or use a pull-up resistor to ensure it remains high during these periods.
  • The recommended method is to use the RY/BY# (Ready/Busy#) signal, which goes low during an erase or program operation and returns high when the operation is complete. You can also use the DQ7 (Data Polling) or DQ6 (Toggle) bits to detect the end of an operation.
  • The WP# signal is used to protect the top or bottom 16KB of the memory array from writes or erases. To enable write protection, tie WP# to VCC. To disable write protection, tie WP# to GND or use a pull-down resistor.
  • The AM29F040B-90JI has an operating temperature range of -40°C to +85°C.
