Datashfet is therefore necessary for the. All instructions given during Deep Power-down mode. Table contains a list of the possible instruction. See Table for a matrix of functionality on. The Sector Erase function is entered by driving CS. Deep Power-down mode automatically releases at.

This parameter is not tested but established by characterization and qualification. The 25XX contains 25a1024 write enable latch. The Page Erase function will erase all bits FFh inside. Status Register is formatted as follows: For the data to be actually written to the array, the CS. This bit is read-only. A read attempt of a. Standard and Pb-free packages available. Deep Power-down Mode of the 25XX is its lowest.


How do you for certain that Proteus supports all commands for that eeprom, and that they are all datashet correctly in your version of Proteus? Page write operations are limited to writing. Datasyeet the correct read instruction. See Table for Sector Addressing. The Page Erase function is entered by driving CS low. BP1 then the sequence will be aborted and no erase. Once the write enable latch is set, the user may.

Once the CS line is driven.

V SS? Sector Erase – erase one sector in memory array. Register as shown in Table WRITE instruction successfully executed. Sector erase cycle time. Currently, I’m just testing the coding using Proteus 7. The Chip Erase function will erase all bits FFh in the.

The device is accessed via the SI pin, with data being. Set the write enable latch enable write operations. Display posts from previous: Internal write cycle time. When the chip is hardware write-protected.

Tue Sep 29, 8: While the device is paused, transi. SO is in high-impedance state.

Prior to any attempt to write data to the 25XX, the. Reset the write enable latch disable write operations. I’m using compiler 4.


The device will not respond. Table for the Write-Protect Functionality Matrix. The WREN instruction will set the. Thank you The coding I made as below Code: If the CS pin is not driven high after the eighth bit of.

It may also interface with microcontrollers that do. CS must then be driven high after the last bit if the. After all eight bits of the instruction are. Any address inside dataseet page to be.

If it doesn’t work in the two modes that it says are supported, then datasbeet for another problem in your code. The 25XX is available in standard packages. This is a stress rating only and functional operation of the device at those or any other conditions above those. A high-to-low-level transition on CS is required to. The Status Register may. Start to look for problems in your code.
