Table 7.
Am29F800 Command Definitions
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 WE or 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. 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 group and 01H for a protected sector group. The complete bus address is
composed of the sector address (A18–A12), A1 = 1, and A0 = 0.
4. Read and program functions in non-erasing sectors are allowed in the Erase Suspend mode.
5. Address bits A18–A11 are don’t care for unlock and command cycles.
