NOTES:
1. X can be VIH or VIL for address or control pins except for RY/BY#, which is either VOL or VOH.
2. RY/BY# output is open drain. When the WSM is ready, Erase is suspended or the device is in deep power-down mode.
RY/BY# will be at VOH if it is tied to VCC through a resistor. RY/BY# at VOH is independent of OE# while a WSM operation
is in progress.
3. RP# at GND ± 0.2V ensures the lowest deep power-down current.
4. A0 and A1 at VIL provide device manufacturer codes in x8 and x16 modes respectively. A0 and A1 at VIH provide device ID
codes in x8 and x16 modes respectively. All other addresses are set to zero.
5. Commands for erase, data program, or lock-block operations can only be completed successfully when VPP = VPPH1 or
VPP = VPPH2.
6. While the WSM is running, RY/BY# in level-mode (default) stays at VOL until all operations are complete. RY/BY# goes to
VOH when the WSM is not busy or in erase suspend mode.
7. RY/BY# may be at VOL while the WSM is busy performing various operations (for example, a Status Register read during a
program operation).
8. The 28F016SV shares an identical device identifier (66A0H in word-wide mode, A0H in byte-wide mode) with the
28F016SA. See application note AP-393 28F016SV Compatibility with 28F016SA for software and hardware techniques to
differentiate between the 28F016SV and 28F016SA.
