This section discusses the features and behaviors most relevant to host system software that interacts with
the S25FL512S memory device.
The S25FL512S device supports 32-bit addresses to enable higher density devices than allowed by previous
generation (legacy) SPI devices that supported only 24-bit addresses. A 24-bit byte resolution address can
access only 16 Mbytes (128 Mbits) of maximum density. A 32-bit byte resolution address allows direct
addressing of up to a 4 Gbytes (32 Gbits) of address space.
Legacy commands continue to support 24-bit addresses for backward software compatibility. Extended 32-bit
addresses are enabled in three ways:
 Bank address register — a software (command) loadable internal register that supplies the high order bits
 Extended address mode — a bank address register bit that changes all legacy commands to expect 32 bits
 New commands — that perform both legacy and new functions, which expect 32-bit address.
The default condition at power-up and after reset, is the Bank address register loaded with zeros and the
extended address mode set for 24-bit addresses. This enables legacy software compatible access to the first
128 Mbits of a device.
Many commands operate on the main flash memory array. Some commands operate on address spaces
separate from the main flash array. Each separate address space uses the full 32-bit address but may only
define a small portion of the available address space.
The main flash array is divided into erase units called sectors. The sectors are organized as uniform
256-kbyte sectors.
Note: This is a condensed table that uses a sector as a reference. There are address ranges that are not
explicitly listed. All 256 kB sectors have the pattern XXXX0000h-XXXXFFFFh.
The RDIDJ command (9Fh) reads information from a separate flash memory address space for device
identification (ID) and Common Flash Interface (CFI) information. See
Interface (ID-CFI) Address Map on page 124
The ID-CFI address space is programmed by Spansion and read-only for the host system.
