MB85RS2MTY(AEC-Q100 Compliant)

DS501-00061-3v1-E



FSSRD

The SSRD command reads data from special sector (a special region of 256 Byte in FeRAM). SSWR op-

code and arbitrary 24 bits address are input to SI followed by 8 bits dummy. The 16-bit upper address is

invalid. Then, 8-cycle clock is input to SCK. SO is output synchronously to the falling edge of SCK. While

reading, the SI value is invalid. When CS is risen, the SSRD command is completed, but keeps on reading

with automatic address increment which is enabled by continuously sending clocks to SCK in unit of 8 cycles

before CS rising. When it reaches the most significant address, roll over is not happen.

The data in special sector is stable between before and after reflow. Refer “ REFLOW CONDITIONS AND

FLOOR LIFE” for the reflow condition.
