Advance Information
8-, 16-, 32-Words Linear Burst Mode with Wrap-
Around
The flash memory of the SST34WA32A3/32A4/3283/3284
device supports a synchronous read operation with a
Linear Burst mode of a pre-determined word length with
wrap-around. Groups of 8, 16, and 32 words can be read in
this way as defined in Table 3.
In 8, 16, and 32-words Linear Burst mode operation, the
starting address of the linear burst sequence is the address
written to the device. Each successive clock cycle
automatically increments the address counter until the top

Address Ranges
address of the group is reached. Once the top address is
reached, the address wraps back to the first address of the
selected group and continues incrementing from there.
An example of an 8-word linear Burst mode with Wrap-
Around is as follows: if the starting address in the 8-word
mode is 11H (8 words group start = 10H, group end =
17H), the address range to be read would be 10H-17H,
and the burst sequence would be 11H -12H -13H - 14H -
15H - 16H - 17H - 10H - and so on.
The RY/BY# pin will indicate when valid data is present on
the data bus.
