The endurance rating in terms of cycles for the SST series Serial Flash family is 10,000 cycles.

The purpose of the Security ID feature in the SST series Serial Flash family is to offer a 256-bit Security ID (Sec ID) feature, which is divided into two parts - a factory-programmed 64-bit segment and a user-programmable 192-bit segment. The factory-programmed segment is programmed with a unique number by SST and cannot be changed, while the user-programmable segment is left unprogrammed for the customer to program as desired. The Security ID can be programmed using the Program SID command and locked using the Lockout SID command to prevent any future writes to it. The Security ID feature enhances security by providing a unique identifier for the device.

The maximum clock frequency for high-speed read operations of the SST series Serial Flash family is 80 MHz.
