ESMT  
(Preliminary)  
F25S04PA  
JEDEC Read-ID  
The JEDEC Read-ID instruction identifies the device as  
F25S04PA and the manufacturer as ESMT. The device  
information can be read from executing the 8-bit command, 9FH.  
Following the JEDEC Read-ID instruction, the 8-bit  
manufacturer’s ID, 8CH, is output from the device. After that, a  
16-bit device ID is shifted out on the SO pin. Byte1, 8CH,  
identifies the manufacturer as ESMT. Byte2, 20H, identifies the  
memory type as SPI Flash. Byte3, 13H, identifies the device as  
F25S04PA. The instruction sequence is shown in Figure 18.  
The JEDEC Read ID instruction is terminated by a low to high  
transition on CE at any time during data output. If no other  
command is issued after executing the JEDEC Read-ID  
instruction, issue a 00H (NOP) command before going into  
Standby Mode ( CE =VIH).
