Instructions

Instructions are used to Read, Write (Erase and Program),

and configure the SST25VF010. The instruction bus cycles

are 8 bits each for commands (Op Code), data, and

addresses. Prior to executing any Byte-Program, Auto

Address Increment (AAI) programming, Sector-Erase,

Block-Erase, or Chip-Erase instructions, the Write-Enable

(WREN) instruction must be executed first. The complete

list of the instructions is provided in Table 6. All instructions

are synchronized off a high to low transition of CE#. Inputs

will be accepted on the rising edge of SCK starting with the

Data Sheet

most significant bit. CE# must be driven low before an

instruction is entered and must be driven high after the last

bit of the instruction has been shifted in (except for Read,

Read-ID and Read-Status-Register instructions). Any low

to high transition on CE#, before receiving the last bit of an

instruction bus cycle, will terminate the instruction in

progress and return the device to the standby mode.

Instruction commands (Op Code), addresses, and data are

all input from the most significant bit (MSB) first.

1. AMS = Most Significant Address

T6.0 1233

AMS = A16 for SST25VF010

Address bits above the most significant bit of each density can be VIL or VIH

2. One bus cycle is eight clock periods.

3. Operation: SIN = Serial In, SOUT = Serial Out

4. X = Dummy Input Cycles (VIL or VIH); - = Non-Applicable Cycles (Cycles are not necessary)

5. Sector addresses: use AMS-A12, remaining addresses can be VIL or VIH

6. Prior to any Byte-Program, AAI-Program, Sector-Erase, Block-Erase, or Chip-Erase operation, the Write-Enable (WREN) instruction

must be executed.

7. Block addresses for: use AMS-A15, remaining addresses can be VIL or VIH

8. To continue programming to the next sequential address location, enter the 8-bit command, AFH,

followed by the data to be programmed.

9. The Read-Status-Register is continuous with ongoing clock cycles until terminated by a low to high transition on CE#.

10. The Enable-Write-Status-Register (EWSR) instruction and the Write-Status-Register (WRSR) instruction must work in conjunction of

each other. The WRSR instruction must be executed immediately (very next bus cycle) after the EWSR instruction to make both

instructions effective.

11. Manufacturer’s ID is read with A0=0, and Device ID is read with A0=1. All other address bits are 00H. The Manufacturer’s and Device

ID output stream is continuous until terminated by a low to high transition on CE#

12. Device ID = 49H for SST25VF010
