The formulae for baud rate calculation as per datasheet are below. This can be achieved with following operations.

Atmel AT45DB642D-CNU, Parallel, Serial-SPI 64Mbit Flash Memory, 6ns; 3V, 8-Pin CASON

Flip Electronics has the expertise, staff, and systems in place to assist you with both routine components and finding a specific component. We are a market leader in sourcing and delivering electronic components. The register comprised of total bytes. By continuing to use this website, you agree to their use.

This flag at45db642x one when transmit buffer is empty and zero when transmit buffer contains data to be transmitted and that has not yet been moved into shift register.

In this case user should read Sector Lockdown Register to determine status of appropriate status lockdown bits. If you have any doubts for the same you can mention it in comments.

Once WP is asserted, the sectors specified by Sector Protection Register will be protected against any program or erase operation. The rest of bits of this register are unused in master SPI mode. During the execution of sector lockdown command if device is powered down then the lockdown of the sector cannot be guaranteed. This flag is set when the entire frame in the transmit shift register has been shifted out and there are no new data in transmit buffer. This register at45db642c user programmable non volatile register that allows the page size of main memory to be configured for either bytes or bytes.


I have left the rest of operations as homework for you guys.

at45sb642d Similar to all other operations, the sector lockdown operation also achieved with the help of 4 opcodes. There are three continuous array read modes. Hence we will write this register as: These 64 bytes are also fixed and cannot be reprogrammed.

LUFA Library: Atmel AT45DBD Dataflash Commands – LUFA/Drivers/Misc/AT45DBD.h

Sector Protection Register is used in order to specify the sectors, which is to be protected or unprotected. It ca be done as below: We also take the testing of our products rather seriously by incorporating several evaluation and inspection tools. Specialists in Our Trade We have a dedicated training program in place for our staff to ensure that the components we receive from our suppliers pass specific quality controls in-house.

Request a quote today so that we can help you find what you are looking for. The default mode of dataflash is Mode 3, hence clock phase bit will be one. Hence the contents of the buffer will be altered from its previous state when this command is issued. This register contains communication mode selection bits, data order bit, clock phase bit. The higher nibble of this register contains baud rate generator scale factor.

Program one time programmable configuration register using opcode sequence. Out of these bytes, first 64 bytes are allocated as one time user programmable space. In order to lockdown particular sector of the device the Sector Lockdown Register must be written with proper value.

This register is used to configure interrupt levels of receive complete interrupt, transmit complete interrupt and data register empty interrupt. To program security register device ah45db642d be clocked with 4 byte opcode with correct sequence with asserting CS pin first.


This site uses cookies. We are compliant to the following standards: The device comes with another feature called sector lockdown mechanism.

The expertise we have in the electronic component industry allows us to work closely with the military and aerospace industry, printing and manufacturing, computers and electronics, the medical field, etc. We will keep data order at45db642c as zero as we want MSB of data word to be transmitted first.


In the current state of the market, quality concerns have become increasingly important. We guarantee the quality of our products, and we have the network to find the most hard-to-find components. Sector protection can be achieved in two ways either by software or by hardware. This bit is unused in master SPI mode. The program security register command uses SRAM buffer for processing.

To find out more, including how to control cookies, see here: The device contains specialized security register which can be used for purposes like unique device serialization or locked key storage. All the three modes have different opcodes and number of dummy bytes that are need to be sent to read data differ for all the three modes.

Those flags are as below: We have a dedicated training program in place for our staff to ensure that the components we receive from our suppliers pass specific quality controls in-house.
