Notes

1. See Table for description of bus operations.

2. All values are in hexadecimal.

3. Except for the following, all bus cycles are write cycle: read cycle, fourth through sixth cycles of the Autoselect commands, fourth cycle of the configuration register

verify and password verify commands, and any cycle reading at RD(0) and RD(1).

4. Data bits DQ15–DQ8 are don’t care in command sequences, except for RD, PD, WD, PWD, and PWD3-PWD0.

5. Entry commands are required to enter a specific mode to enable instructions only available within that mode.

6. If both the Persistent Protection Mode Locking Bit and the Password Protection Mode Locking Bit are set at the same time, the command operation aborts and returns

the device to the default Persistent Sector Protection Mode during 2nd bus cycle. Note that on all future devices, addresses equal 00h, but is currently 77h for the

WS512P only.

7. Exit command must be issued to reset the device into read mode; device may otherwise be placed in an unknown state.

8. “All PPB Erase” command pre-programs all PPBs before erasure to prevent over-erasure.

9. Entire two bus-cycle sequence must be entered for each portion of the password.

10. Full address range is required for reading password.

12.1 Common Flash Memory Interface

The Common Flash Interface (CFI) specification outlines device and host system software interrogation handshake, which allows

specific vendor-specified software algorithms to be used for entire families of devices. Software support can then be device-

independent, JEDEC ID-independent, and forward- and back-ward-compatible for the specified flash device families. Flash vendors

can standardize their existing interfaces for long-term compatibility.

This device enters the CFI Query mode when the system writes the CFI Query command, 98h, to address (BA)555h any time the

device is ready to read array data. The system can read CFI information at the addresses given in Tables – within that bank. All

reads outside of the CFI address range, within the bank, returns non-valid data. Reads from other banks are allowed, writes are not.

To terminate reading CFI data, the system must write the reset command.

The following is a C source code example of using the CFI Entry and Exit functions. Refer to the Cypress Low Level Driver User’s

Guide (available on www.Cypress.com) for general information on Cypress Flash memory software development guidelines.

/* Example: CFI Entry command */

*( (UINT16 *)bank_addr + 0x555 ) = 0x0098;

/* write CFI entry command

/* write cfi exit command

/* Example: CFI Exit command */

*( (UINT16 *)bank_addr + 0x000 ) = 0x00F0;

For further information, please refer to the CFI Specification (see JEDEC publications JEP137-A and JESD68.01). Please contact

your sales office for copies of these documents.
