Legend:
X = Don’t care
RA = Address of the memory location to be read.
RW = Data read from location RA during read operation.
PA = Address of the memory location to be programmed.
Addresses are latched on the falling edge of the WE# pulse.
PW = Data to be programmed at location PA. Data is latched
on the rising edge of WE#.
SA = Address of the sector to be erased. Refer to Table 8 for
sector addresses.
Notes:
1. Write protect must not be enabled for proper operation of
all commands. No command required for reading array
data, and can thus be done with write protect enabled.
2. During word addressing, CEL# = 0, CEH# = 0, and
address is applied to Memory Device Pair 0 (S0 and S1).
On 4 Mbyte cards, address for Memory Device Pair 1 =
(Addr) + 200000h, and address is applied to Memory
Device Pair 1 (S2 and S3). For host-to-card address bit
connections, see Figure 2.
3. All values are in hexadecimal.
4. The last bus cycle in an autoselect command sequence is
a read operation.
5. Word = high byte + low byte.
6. Address bits = X = Don’t Care for all commands except for
Read Address (RA), Program Address (PA), and Sector
Address (SA).
7. The Erase Suspend command is valid only during a
sector erase operation. Refer to “Sector Erase Suspend”.
8. The Erase Resume command is valid only during the
Erase Suspend mode.
9. See Table 4 for bus operations.
