Legend:
RA = Address of the memory location to be read.
RD = 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 WEor CE pulse.
PD = Data to be programmed at location PA. Data is latched on the rising edge of WE or CE pulse.
SA = Address of the sector to be erased or verified. Address bits A18–A12 uniquely select any sector.
Notes:
1. All values are in hexadecimal.
2. See Tables 1 and 2 for description of bus operations.
3. The data is 00h for an unprotected sector and 01h for a protected sector. The complete bus address is composed of the sector
address on A18–A12 and 02h on A7–A0.
4. Read and program functions in non-erasing sectors are allowed in the Erase Suspend mode. The Erase Suspend command
is valid only during a sector erase operation.
5. The Erase Resume command is valid only during the Erase Suspend mode.
6. Unless otherwise noted, address bits A18–A11 = X = don’t care.
