• Description: 64 Mbit SPI Serial Dual I/O Flash
• Manufacturer: SST [Silicon Storage Technology, Inc]

64 Mbit SPI Serial Dual I/O Flash
SST25VF064C
Enable-Hold (EHLD)
The 8-bit command, AAH, Enable-Hold instruction enables
the HOLD functionality of the RST#/HOLD# pin. CE# must
remain active low for the duration of the Enable-Hold
Read-ID (RDID)
The Read-ID instruction (RDID) identifies the device as
SST25VF064C and manufacturer as SST. The device
information can be read from executing an 8-bit command,
90H or ABH, followed by address bits A
Read-ID instruction, the manufacturer’s ID is located in
address 00000H and the device ID is located in address
00001H. Once the device is in Read-ID mode, the manu-
