Legend:
BA = Address of bank switching to autoselect mode, bypass
mode, or erase operation. Determined by PL127J: Amax:A20,
PL064J: Amax:A19, PL032J: Amax:A18.
PA = Program Address (Amax:A0). Addresses latch on falling
edge of WE# or CE# pulse, whichever happens later.
PD = Program Data (DQ15:DQ0) written to location PA. Data
latches on rising edge of WE# or CE# pulse, whichever happens
first.
RA = Read Address (Amax:A0).
RD = Read Data (DQ15:DQ0) from location RA.
SA = Sector Address (Amax:A12) for verifying (in autoselect
mode) or erasing.
WD = Write Data. See “Configuration Register” definition for
specific write data. Data latched on rising edge of WE#.
X = Don’t care
Notes:
1. See Table 1 for description of bus operations.
2. All values are in hexadecimal.
3. Shaded cells in table denote read cycles. All other cycles are
write operations.
4. During unlock and command cycles, when lower address bits
are 555 or 2AAh as shown in table, address bits higher than
A11 (except where BA is required) and data bits higher than
DQ7 are don’t cares.
5. No unlock or command cycles required when bank is reading
array data.
6. The Reset command is required to return to reading array
(or to erase-suspend-read mode if previously in Erase
Suspend) when bank is in autoselect mode, or if DQ5 goes
high (while bank is providing status information).
7. Fourth cycle of autoselect command sequence is a read
cycle. System must provide bank address to obtain
manufacturer ID or device ID information. See Autoselect
Command Sequence section for more information.
8. The data is C0h for factory and customer locked and 80h for
factory locked.
9. The data is 00h for an unprotected sector group and 01h for
a protected sector group.
10. Device ID must be read across cycles 4, 5, and 6. PL127J
(X0Eh = 2220h, X0Fh = 2200h),PL064J (X0Eh = 2202h,
X0Fh = 2201h), PL032J (X0Eh = 220Ah, X0Fh = 2201h).
11. System may read and program in non-erasing sectors, or
enter autoselect mode, when in Program/Erase Suspend
mode. Program/Erase Suspend command is valid only
during a sector erase operation, and requires bank address.
12. Program/Erase Resume command is valid only during Erase
Suspend mode, and requires bank address.
13. Command is valid when device is ready to read array data or
when device is in autoselect mode.
14. WP#/ACC must be at VID during the entire operation of
command.
15. Unlock Bypass Entry command is required prior to any
Unlock Bypass operation. Unlock Bypass Reset command is
required to return to the reading array.
