This Data Sheet may be revised by subsequent versions 1 or modifications due to changes in technical specifications. This can be used as an extra software protection mechanism, when the device is not in active use, to protect the device from inadvertent Write, Program or Erase instructions.

I have spi through voltage dividers to the chip, with vcc to 3.

You can still use this for chip select. During voltage transitions, inputs may undershoot V ss to It is possible to write less than bytes, which will be written at the starting address, not affecting the rest of the data on datawheet same page. All other instructions are ignored while the device is in the Deep Power-down mode. Before this can be applied, the bytes of memory need to have been erased to all 1s FFh.

Read Data Instruction Sequence Diagram This Data Sheet may be revised by subsequent versions or modifications due to changes in technical specifications. And forgot to mention, this all started to work after a power cycle on the chip. Before this can be applied, the.

Full text of ” Datasheet: The Status Register contains datahseet number of status and control bits that can be read or set as appropriate by specific instructions. There are bytes of OTP memory, which can be used to store various security data.

8 Megabit Serial Flash Memory With 4Kbytes Uniform Sector

For Mode 0 the SCK signal is normally low. Other mikroE Libraries used in the example: There is 1 item in your cart. Continue shopping Proceed to checkout. The provided application example demonstrates the functionality of the library functions. Data can be read by the Read Data Bytes instruction. The device is first selected by driving Chip Select Low. The used flash module has very good endurance and it can withstand up towrite cycles, with the data retention period of about 20 years.

Before this can be applied, the bytes of memory need to have been erased to all 1s FFh. I connected the hold pin to 3.

When set to 1such a cycle is in progress, when reset to 0 no such cycle is in progress. To spread this overhead, the Page Program PP instruction allows up to bytes to be programmed at. Usually, every write operation will be prefixed with the WREN instruction. Chip Select CS must be driven High after the eighth bit of the last address byte has been latched in, otherwise the Sector Erase SE instruction is not executed.

This is followed by the internal Program cycle of duration tPP. The instruction sequence is shown in Figure The EN25F80 can be configured to protect part of the memory as the software protected mode.

EN25F80 Hoja de datos ( Datasheet PDF ) – 8 Mbit Serial Flash Memory

The primary difference between Mode 0 and Mode 3, as shown in Figure 3, concerns the normal state of the SCK signal when the SPI bus master is in standby and data is not being transferred to the Serial Datasneet. Until datashheet bit is 0, the OTP memory block can be freely programmed, just like any other block.

When deselected, the devices power consumption will be at standby levels unless an internal erase, program or status register cycle is in progress. A dedicated WP write protect pin is used to put the device into the hardware write protect mode.

Power-up Timing Table 7.

It is also possible to read the Status Register continuously, as shown in Figure 7. In the case of SE and BE, exact bit address is a must, any less or more will cause the command to be ignored. If the 8 least significant address bits A7-A0 are not all zero, all transmitted data that goes beyond the end of the current page are programmed from the start address of the same page from the address whose 8 least significant bits A7-A0 are all zero.

When CS is brought low the device will be selected, power consumption will increase to active levels and instructions can be written to and data read from the device.
