Preliminary

Digital Read and Write

The ISD5216 chip allows writing of digital data as well as analog. Any address can be used for

either analog or digital storage, but not both at the same time.

The demo application shows the capability to read and write text into memory and also read the

raw data out of any memory cell.

The Address box at the top of the window is shared for all operations, type in a hex number

between 0 and FFFF to specify a 64 bit block. If no address is specified, the application is going

to use the current address pointer. For details about addressing, please refer to the datasheet.

Reading and Writing Strings

Erase: Pressing this button will erase one page of data (2048 bits), it is not possible to erase a

smaller number of bits.

Read Data: Reads a string of characters previously stored with the Write Data button.

Write Data: Writes a string to non-volatile digital memory (max 256 characters)

Reading Raw Data

The program allows reading of the raw data from any position in the array. Use the address box

at the top of the window or leave it blank for using the current address.

Type the number of 64 bit words to read (a decimal number) and press Read Raw Data to

retrieve the data.
