AT25010A/020A/040A [Preliminary]
3402A–SEEPR–10/3/03
The AT25010A/020A/040A is capable of an 8-byte PAGE WRITE operation. After each
byte of data is received, the three low order address bits are internally incremented by
one; the six high order bits of the address will remain constant. If more than 8 bytes of
data are transmitted, the address counter will roll over and the previously written data
will be overwritten. The AT25010A/020A/040A is automatically returned to the write dis-
able state at the completion of a WRITE cycle.
NOTE: If the WP pin is brought low or if the device is not Write enabled (WREN), the
device will ignore the Write instruction and will return to the standby state, when CS is
brought high. A new CS falling edge is required to re-initiate the serial communication.
