2.2.2.8
New Features
The FS-S family introduces new features to Spansion SPI category memories:
 Single 1.8V power supply for core and I/O voltage.
 Configurable initial read latency (number of dummy cycles) for faster initial access time or higher clock rate
read commands
 Quad Peripheral Interface (QPI, 4-4-4) read mode in which all transfers are 4 bits wide, including
instructions
 JEDEC JESD216 standard, Serial Flash Discoverable Parameters (SFDP) that provide device feature and
configuration information.
 Evaluate Erase Status command to determine if the last erase operation on a sector completed
successfully. This command can be used to detect incomplete erase due to power loss or other causes.
This command can be helpful to Flash File System software in file system recovery after a power loss.
 Advanced Sector Protection (ASP) Permanent Protection. A bit is added to the ASP register to provide the
option to make protection of the Persistent Protection Bits (PPB) permanent. Also, when one of the two
ASP protection modes is selected, all OTP configuration bits in all registers are protected from further
programming so that all OTP configuration settings are made permanent. The OTP address space is not
protected by the selection of an ASP protection mode. The Freeze bit (CR1V[0]) may be used to protect the
OTP Address Space.
