Known Differences from Prior Generations
Error Reporting
Prior generation FL memories either do not have error status bits or do not set them if program or erase is attempted on a protected
sector. The FL-S family does have error reporting status bits for program and erase operations. These can be set when there is an
internal failure to program or erase or when there is an attempt to program or erase a protected sector. In either case the program or
erase operation did not complete as requested by the command.
Secure Silicon Region (OTP)
The size and format (address map) of the One Time Program area is different from prior generations. The method for protecting
each portion of the OTP area is different. For additional details see Secure Silicon Region (OTP) on page 59.
Configuration Register Freeze Bit
The configuration register Freeze bit CR1[0], locks the state of the Block Protection bits as in prior generations. In the FL-S family it
also locks the state of the configuration register TBPARM bit CR1[2], TBPROT bit CR1[5], and the Secure Silicon Region (OTP)
Sector Architecture
The FL127S has sixteen 4-kbyte sectors that may be located at the top or bottom of address space. Other members of the FL-S
Family and FL-P Family have thirty two 4-kbyte sectors that may be located at the top or bottom of address space.
These smaller parameter sectors may also be removed, leaving all sectors uniform in size, depending on the selected configuration
Sector Erase Commands
The command for erasing an 8-kbyte area (two 4-kbyte sectors) is not supported.
The command for erasing a 4-kbyte sector is supported only for use on the 4-kbyte parameter sectors at the top or bottom of the
device address space. The 4-kbyte erase command will only erase the parameter sectors.
The erase command for 64-kbyte sectors is supported when the configuration option for 4-kbyte parameter sectors with 64-kbyte
uniform sectors is used. The 64-kbyte erase command may be applied to erase a group of sixteen 4-kbyte sectors.
The erase command for a 256-kbyte sector replaces the 64-kbyte erase command when the configuration option for 256-kbyte
uniform sectors is used.
Deep Power Down
The Deep Power Down (DPD) function is not supported in FL-S family devices.
The legacy DPD (B9h) command code is instead used to enable legacy SPI memory controllers, that can issue the former DPD
command, to access a new bank address register. The bank address register allows SPI memory controllers that do not support
more than 24 bits of address, the ability to provide higher order address bits for commands, as needed to access the larger address
space of the 256-Mbit and 512-Mbit density FL-S devices. For additional information see Extended Address on page 48.
Hardware Reset
A separate hardware reset input is provided in packages with greater than 8 connections. In 8-connection packages, a new option is
provided to replace the HOLD# / IO3 input with an IO3 / RESET# input to allow for hardware reset in small packages.
