Notes:

1. Address bit A15, A16, A17 and A18 = X = don¢t care for all address commands except for Program

address (PA) and sector address (SA).

2. Bus operations are defined in Table 4.

3. RA = Address of the memory location to be read. PA = Address of the memory location to be programmed.

Addresses are latched on the falling edge of WE. SA = Address of the sector to be erased. The combination

of A16, A17 and A18 will uniquely select the sector.

4. RD = Data from the selected address location (RA) during read operation. PD = Data to be programmed at the

selected memory location (PA). Data is latched at the falling edge of /WE.

5. Auto select command can be used to evaluate whether a block is protected or not by using at the fourth address 02H.

This is similar to placing A9 to High Voltage.

Auto Select Command

The BM29F040 contains two different procedures for the autoselect mode. One is the traditional

PROM programmer methodology (by taking Address pin A9 to VID) and the other is by writing the

Auto Select command sequence into the command register. Following the third bus cycle write

command, a read cycle from Address 00H retrieves the BMI manufacturer code ADH, and a read

cycle at 01H retrieves the device code of 40H. Scanning the sector addresses (A16, A17, A18) while

(A6, A1, A0) = (0, 1, 0) will produce a logical at device output DQ0 for a protected sector. See table 5

for more details.

To terminate this operation, it is necessary to write the read/ reset command to the command
