AT28C64E-15PI Frequently Asked Questions (FAQ)
-
The maximum operating temperature range for the AT28C64E-15PI is -40°C to +85°C.
-
Page writes and block erases should be handled using the specific command sequences outlined in the datasheet. It's essential to follow the recommended programming algorithm to ensure data integrity and prevent device damage.
-
The recommended power-up sequence is to apply VCC before VPP, and the recommended power-down sequence is to remove VPP before VCC. This helps prevent unwanted programming or erasure of the device.
-
The device's status can be determined by monitoring the RDY/BUSY output pin, which goes low during a write or erase operation and returns high when the operation is complete.
-
The VPP pin is used to supply the programming voltage for the device. It should be connected to a 12V ± 0.5V power source during programming and erased operations, and can be tied to VCC or left unconnected during read operations.
