JEDEC-ID Read (SPI Protocol)

Using traditional SPI protocol, the JEDEC-ID Read

instruction identifies the device as SST26VF032B/

032BA and the manufacturer as Microchip. To execute

a JECEC-ID operation the host drives CE# low then

sends the JEDEC-ID command cycle (9FH).

Immediately

following

the

command

cycle,

SST26VF032B/032BA output data on the falling edge

of the SCK signal. The data output stream is continu-

ous until terminated by a low-to-high transition on CE#.

The device outputs 3 bytes of data: manufacturer,

device type, and device ID, see Table 5-4. See

Figure 5-16 for instruction sequence.

Read Quad J-ID Read (SQI

Protocol)

The Read Quad J-ID Read instruction identifies the

device as SST26VF032B/032BA and manufacturer as

Microchip. To execute a Quad J-ID operation the host

drives CE# low and then sends the Quad J-ID com-

mand cycle (AFH). Each cycle is two nibbles (clocks)

long, most significant nibble first.

Immediately following the command cycle and one

dummy cycle, SST26VF032B/032BA output data on

the falling edge of the SCK signal. The data output

stream is continuous until terminated by a low-to-high

transition of CE#. The device outputs 3 bytes of data:

manufacturer, device type, and device ID, see

Table 5-4. See Figure 5-17 for instruction sequence.
