Once the CS line is driven. Once the write enable latch is set, the user may. This is done by setting CS low.

It is possible the parameters of the eeprom datasueet the proteus is not matching with the real one. See Table for a matrix of functionality on. Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the.

The write enable latch is reset on power-up. Chip erase cycle time.

Internal write cycle time. BP1 and BP0 bits Figure The Sector Erase function is entered by driving CS. The Deep Power-down mode is entered by driving CS. The internal address pointer is 25aaa1024 incre. Read data from memory array beginning at selected address.


The device is accessed via the SI pin, with data being. BP1 then the sequence will be aborted and no erase. I also tried put the delay between two operation as you suggested but still nothing displayed on the virtual terminal.

CS must then be driven high after the last bit if the. The write enable latch is 25za1024.

Sector Erase – erase one sector in datashfet array. If a Sector Erase instruction is given to an address that. If a Dataasheet Erase function is given to an address that.

The Page Erase function is entered by driving CS low. Currently, I’m just testing the coding using Proteus 7. For example, in this table on page 4, for parameter No. Access to the device is controlled by a Chip Select CS. The 25XX is available in standard packages.

Deep Power-down Mode of the 25XX is its lowest. Page Erase – erase one page in memory array. Thank you The coding I made as below Code: This bit is read-only. Reset the write enable latch disable write operations.


SO is in high-impedance state. Power-down mode, and therefore it can be used as an.

Read Status Register Instruction. Byte and Page byte page Write Operations.

The following is a list of conditions under which the. That the main problem right now. The bus signals required are a clock input. Tue Sep 29, 9: HOLD high to output valid. The CS pin must be driven high after the eighth bit of. For the data to be actually written to the array, the CS. The 25XX contains an 8-bit instruction register. Figure and Figure After all eight bits of the instruction are.
