Instruction
Instruction set: extended SPI protocol (page 2 of 2)
1) The Number of dummy clock cycles is configurable by user
2) Subsector erase instruction is only available in Bottom or Top parts
Read Identification (RDID)
The Read Identification (RDID) instruction allows to read the device identification data:
The manufacturer identification is assigned by JEDEC, and has the value 20h. The device
identification is assigned by the device manufacturer, and indicates the memory type in the
first byte (BAh), and the memory capacity of the device in the second byte (18h). The UID is
composed by 17 read only bytes, containing the length of the following data in the first byte
(set to 10h), 2 bytes of Extended Device ID (EDID) to identify the specific device
configuration (Top, Bottom or uniform architecture, Hold or Reset functionality), and 14
bytes of the optional Customized Factory Data (CFD) content. The CFD bytes can be
factory programmed with customers data upon their demand. If the customers do not make
requests, the devices are shipped with all the CFD bytes programmed to zero (00h).
Any Read Identification (RDID) instruction while an Erase or Program cycle is in progress, is
not decoded, and has no effect on the cycle that is in progress.
The device is first selected by driving Chip Select (S) Low. Then, the 8-bit instruction code
for the instruction is shifted in. After this, the 24-bit device identification, stored in the
memory, the 17 bytes of UID content will be shifted out on Serial Data output (DQ1). Each
bit is shifted out during the falling edge of Serial Clock (C).
The instruction sequence is shown in Figure 10.
The Read Identification (RDID) instruction is terminated by driving Chip Select (S) High at
any time during data output.
