Common Flash Memory Interface (CFI) Mode
Query Instruction and Common Flash memory Interface (CFI) Mode
Through Common Flash Interface (CFI) operations it is possible to access the operating
characteristics, structure and vendor specific information, such as identifying information, memory size,
byte/word configuration, operating voltages and timing information of this device. From the Read array
mode writing CFI Read instruction 98h to the address "55h"/"AAh" (Word/Byte, respectively), the
device will gain access to the CFI Query Mode. Once in the CFI mode data can be read using the
addresses given in Table 7-19 thru 7-22.
A reset instruction must be executed to exit CFI mode and the device will return to read array mode.
CFI mode: Identification Data Values (All Values in these tables are hexadecimal)
Description
Query-unique ASII string “QRY”
Primary vendor instruction set and control interface ID code
Address for primary algorithm extended query table
Alternate vendor instruction set and control interface ID code
Address for alternate algorithm extended query table
